Net income

Answers

Answer 1

The company's price-earnings ratio for a company that reported net income of $275,270 with $20,390 for preferred dividends and 36,000 shares of common stock, is 16.79.

What is the price-earnings ratio?

The price-earnings ratio represents the per-dollar amount that an investor can expect to invest in a company in order to receive $1 of that company's net earnings.

The price-earnings (P/E) ratio is also referred to as the price multiple.

The price-earnings (P/E) ratio compares the market price with the earnings per share.

Net income = $275,270

Preferred Dividends = $20,390

Net income available to Common Stockholders = $254,880 ($275,270 - $20,390)

Number of common stock outstanding = 36,000 shares

Market price per share of common stock = $118.87

Earnings per share (Common Stock) = $7.08 ($254,880/36,000)

Price-earnings ratio = Market price per share/Earnings per share

= 16.79 ($118.87/$7.08).

Allan painted the circular patch on his driveway. He used the formula below to calculate the area of the circular patch. The diameter of the circular patch was 20 meters. What was the area of the patch? Assume pi=3.14

Answers

Answer: 314 square meters

Step-by-step explanation:

The formula for the area of a circle is given by A = πr^2, where r is the radius of the circle. Since the diameter of the circular patch is given as 20 meters, the radius would be half of that or 10 meters.

So, using the formula, we can calculate the area of the circular patch as follows:

A = πr^2

A = π(10)^2

A = 3.14(100)

A = 314 square meters

Therefore, the area of the circular patch is 314 square meters.

A water cooler springs a leak and empties in 2 minutes. The graph below shows the rate at which water leaks from the cooler as a function of time.

Answers

The amount of water that was in the cooler before it started leaking was 6 gallons.

Describe Integration?

Integration is a mathematical process that involves finding the integral of a function. It is the reverse operation of differentiation, which involves finding the derivative of a function. The integral of a function is a measure of the area under the curve of the function, between two given limits of integration.

The graph shows the rate at which water leaks from the cooler as a function of time, which means that the y-axis represents the rate of leakage in gallons per minute (gal/min), and the x-axis represents the time in minutes.

Since we know that the cooler emptied in 2 minutes, we can integrate the leakage rate over the time interval [0, 2] to find the total amount of water that leaked out:

Total amount of water leaked = ∫[0,2] leakage rate(t) dt

The leakage rate is given by the graph, which consists of a straight line connecting two points: (0,6) and (2,0). We can express this line as a linear equation in slope-intercept form:

leakage rate(t) = mt + b

where m is the slope of the line and b is the y-intercept. To find the slope, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0,6) and (x2, y2) = (2,0). Plugging in the values, we get:

m = (0 - 6) / (2 - 0) = -3

So the equation of the line is:

leakage rate(t) = -3t + 6

Now we can integrate this equation over the time interval [0, 2] to get the total amount of water leaked:

Total amount of water leaked = ∫[0,2] (-3t + 6) dt

= [-3t²/2 + 6t] from 0 to 2

= (-3(2)²/2 + 6(2)) - (-3(0)²/2 + 6(0))

= (6 - 0) - (0 - 0)

= 6 gallons

Therefore, the amount of water that was in the cooler before it started leaking was 6 gallons.

The complete question is :

6. Deepa's age is three times that of her brother Devan. After 2 years Deepa's age would
be two times that of Devan. How old are they now?

Answers

Answer:

Devan's age = 2 years.

Deepa's age = 6 years.

Step-by-step explanation:

Framing and solving algebraic equation:

Present age:      

 Let the present age of Devan = x

             Present age of Deepa = 3x

After 2 years:

                     Age of Devan = x + 2

                     Age of Deepa = 3x + 2

     Deepa's age = 2* Devan's age

          3x + 2        = 2 *(x + 2)

                3x + 2  = 2x + 2*2    {Use distributive property}

               3x + 2   = 2x + 4

  Subtract '2' from both sides,

                           3x = 2x + 4 - 2

                           3x = 2x + 2

Subtract '2x' from both sides,

                   3x  - 2x = 2

                             x = 2

Devan's age = 2 years.

Deepa's age = 3*2

                      = 6 years  

Answer:

Deepa is currently 6 years old
Devan is currently 2 years old.

Step by step explanation:

Let's assume that Devan's current age is x years.

According to the problem, Deepa's age is three times that of Devan's age, which means Deepa's current age is 3x years.

After 2 years,

Devan's age will be x + 2 years,

and

Deepa's age will be 3x + 2 years.

The problem states that Deepa's age after 2 years will be twice Devan's age after 2 years.

So, we can write the equation:

3x + 2 = 2(x + 2)

Solving for x, we get:

3x + 2 = 2x + 4

x = 2

Therefore, Devan's current age is 2 years.

Using this, we can find Deepa's current age, which is three times Devan's age:

Deepa's current age = 3x = 3(2) = 6 years

So, Deepa is currently 6 years old and Devan is currently 2 years old.

Answers

(a) T is one-to-one if and only if T carries linearly independent subsets of V onto linearly independent subsets of W.

(b) If T is one-to-one, then S is linearly independent if and only if T(S) is linearly independent.

(c) If β is a basis for V and T is one-to-one and onto, then T(β) is a basis for W.

(a) Assume T is one-to-one. Let S be a linearly independent subset of V, and suppose T(S) is linearly dependent. Then there exist distinct vectors s1, s2, ..., sn in S such that T(s1), T(s2), ..., T(sn) are linearly dependent. This means that there exist scalars c1, c2, ..., cn, not all zero, such that c1T(s1) + c2T(s2) + ... + cnT(sn) = 0. Since T is linear, we have T(c1s1 + c2s2 + ... + cnsn) = 0. But since T is one-to-one, this implies that c1s1 + c2s2 + ... + cnsn = 0, contradicting the assumption that S is linearly independent. Hence, T(S) must be linearly independent.

Conversely, assume that T carries linearly independent subsets of V onto linearly independent subsets of W. Let v1 and v2 be distinct vectors in V, and suppose T(v1) = T(v2). Then {v1, v2} is linearly dependent, which implies that there exist scalars c1 and c2, not both zero, such that c1v1 + c2v2 = 0. Applying T to both sides yields c1T(v1) + c2T(v2) = 0, which implies that T(v1) and T(v2) are linearly dependent. This contradicts the assumption that T carries linearly independent subsets of V onto linearly independent subsets of W. Hence, T must be one-to-one.

(b) Assume T is one-to-one and let S be a subset of V. Suppose S is linearly independent and that T(S) is linearly dependent. Then there exist distinct vectors s1, s2, ..., sn in S such that T(s1), T(s2), ..., T(sn) are linearly dependent. This means that there exist scalars c1, c2, ..., cn, not all zero, such that c1T(s1) + c2T(s2) + ... + cnT(sn) = 0. Since T is linear, we have T(c1s1 + c2s2 + ... + cnsn) = 0. But since T is one-to-one, this implies that c1s1 + c2s2 + ... + cnsn = 0, contradicting the assumption that S is linearly independent. Hence, T(S) must be linearly independent.

Conversely, assume that T(S) is linearly independent whenever S is a linearly independent subset of V. Let v1 and v2 be distinct vectors in V, and suppose T(v1) = T(v2). Then {v1, v2} is linearly dependent, which implies that there exist scalars c1 and c2, not both zero, such that c1v1 + c2v2 = 0. Since {v1, v2} is linearly dependent, we have either v1 = 0 or v2 = 0. Without loss of generality, assume v1 = 0. Then T(v1) = 0 = T(v2), and hence T({v1, v2}) = {0} is linearly dependent. This contradicts the assumption that T carries linearly independent subsets of V onto linearly independent subsets of W. Hence, S must be linearly independent.

(c) First, we will show that T(β) spans W. Let w be an arbitrary vector in W. Since T is onto, there exists some vector v in V such that T(v) = w. Since β is a basis for V, there exist scalars c1, c2, ..., cn such that v = c1v1 + c2v2 + ... + cnvn. Applying T to both sides, we have w = T(v) = T(c1v1 + c2v2 + ... + cnvn) = c1T(v1) + c2T(v2) + ... + cnT(vn), which implies that T(β) spans W.

Next, we will show that T(β) is linearly independent. Suppose there exist scalars c1, c2, ..., cn such that c1T(v1) + c2T(v2) + ... + cnT(vn) = 0. Applying T to both sides, we have T(c1v1 + c2v2 + ... + cnvn) = 0. But since T is one-to-one, this implies that c1v1 + c2v2 + ... + cnvn = 0, which implies that c1 = c2 = ... = cn = 0, since β is a basis for V. Hence, T(β) is linearly independent.

Since T(β) spans W and is linearly independent, it is a basis for W. Therefore, if β is a basis for V and T is one-to-one and onto, then T(β) is a basis for W.

Parameterizing a surface over a rectangle Parameterizing the surface z = x²+2y² over the rectangular region R defined by -3 ≤ x ≤ 3, −1 ≤ y ≤ 1 are falls under the range of R.

Let's start by expressing x and y as functions of u and v. Since x varies between -3 and 3 over R, we can use the following parameterization for x:

x = u

where u varies between -3 and 3. Similarly, since y varies between -1 and 1 over R, we can use the following parameterization for y:

y = v

where v varies between -1 and 1.

Next, we can use these parameterizations for x and y to express z as a function of u and v. Substituting x = u and y = v into the equation z = x² + 2y², we get:

z = u² + 2v²

So, the parameterization of the surface z = x² + 2y² over the rectangular region R is given by:

x = u, y = v, z = u² + 2v²

where -3 ≤ u ≤ 3 and -1 ≤ v ≤ 1.

A fair coin is tossed five times. Explain why the probability of getting exactly three heads is 0.3125.​

Answers

The value of the probability is 0.3125 and this is proved by the calulations below

How to explain the value of the probability

The probability of getting exactly 3 heads in 5 coin tosses can be calculated by multiplying the probability of one specific combination of 3 heads and 2 tails by the number of possible combinations.

The probability of one specific combination, for example HHTTT, is (1/2)^5 = 1/32, because each toss has a 1/2 chance of being a head or a tail.

There are 5C3 = 10 possible combinations of 3 heads and 2 tails in 5 tosses.

For example: HHTTT, HTHTT, HTTHT, HTHHT, TTHHH, etc.

Therefore, the probability of getting exactly 3 heads is:

Probability = 10 * (1/32)

Probability = 10/32

Probability = 0.3125.

What is triangle?

A triangle is a three-sided polygon, which is a closed two-dimensional shape with straight sides. In a triangle, the three sides connect three vertices, or corners, and the angles formed by these sides are called the interior angles of the triangle. The sum of the interior angles of a triangle is always 180 degrees. Triangles can be classified by their side lengths and angle measurements. For example, an equilateral triangle has three sides of equal length, and all of its angles are 60 degrees; an isosceles triangle has two sides of equal length, and its base angles are also equal; a scalene triangle has three sides of different lengths, and all of its angles are also different. Triangles are a fundamental shape in mathematics and geometry, and they have numerous applications in fields such as architecture, engineering, physics, and more.

Given by the question.

Based on the given information, we can start by drawing a diagram of triangle ABC and the segments AH, BJ, CI, CJ, and BI as described.

Since CG = BG, we can draw the perpendicular bisector of side AC passing through point G, which will intersect side AB at its midpoint M.

Now, we can see that triangle CGB is isosceles with CG = BG, so the perpendicular bisector of side CB also passes through point G. This means that G is the circumcenter of triangle ABC, and therefore, the distance from G to any vertex of the triangle is equal to the radius of the circumcircle.

Next, we can use the fact that AJ and BJ are congruent to draw the altitude from point J to side AB, which we will call JN. Similarly, we can draw the altitude from point I to side BC, which we will call IM.

Since AJ and BJ are congruent, the altitude JN will also be the perpendicular bisector of side AB, so it will pass through point M. Similarly, the altitude IM will pass through point G, which is the circumcenter of triangle ABC.

Now, we can use the Pythagorean theorem to find the lengths of JN and IM in terms of the given lengths:

[tex]JN^{2}= AJ^{2} -AN^{2} \\ = ( AH+HN)^{2} - AN^{2} \\=AH^{2} +2AH*HN+HN^{2}-AN^{2} \\[/tex]

[tex]IM^{2}= CI^{2} -CM^{2} \\=( CG-GM)^{2} -CM^{2} \\CG^{2}-2CG*GM+GM^{2} -CM^{2}[/tex]

Since CG = BG and GM = BM (since M is the midpoint of AB), we can simplify the expression for IM^2 as follows:

[tex]IM^{2}[/tex] = [tex]BG^{2}[/tex] - 2BG * BM + [tex]BM^{2}[/tex] - [tex]CM^{2}[/tex]

= [tex]BG^{2}[/tex] - [tex]BM^{2}[/tex] - [tex]CM^{2}[/tex]

Now, we can use the fact that BJ and CI intersect at point K to find the length of KJ:

KJ = BJ - BJ * (CK/CI)

= BJ * (1 - CK/CI)

= BJ * (1 - BM/CM)

To find BM/CM, we can use the fact that triangle BCI is isosceles with BI = CI, so the altitude IM is also a median of the triangle. This means that CM = 2/3 * BI. Similarly, we can find BJ in terms of JN using the fact that triangle ABJ is isosceles with AJ = BJ:

BJ = 2 * JN

Substituting these expressions into the equation for KJ, we get:

KJ = 2 * JN * (1 - 2/3 * BI/CM)

Now, we just need to find BI/CM in terms of the given lengths. Using the fact that triangle BCI is isosceles with BI = CI, we can find BI in terms of CG:

BI = CG - CI

Substituting this expression into the equation for [tex]IM^{2}[/tex]and simplifying, we get:

[tex]IM^{2}[/tex] =[tex]BG^{2}[/tex] - CG * CI

let z=a+bi/a-bi where a and b are real numbers. prove that z^2+1/2z is a real number.

Answers

Answer:

Step-by-step explanation:

To prove that z^2 + 1/2z is a real number, we need to show that the imaginary part of z^2 + 1/2z is equal to zero.

We know that z = (a+bi)/(a-bi)

Multiplying the numerator and denominator by the complex conjugate of the denominator, we get

z = (a+bi)(a+bi)/(a-bi)(a+bi)

z = (a^2 + 2abi - b^2)/(a^2 + b^2)

Expanding z^2, we get:

z^2 = [(a^2 + 2abi - b^2)/(a^2 + b^2)]^2

z^2 = (a^4 + 2a^2b^2 + b^4 - 2a^2b^2 + 4a^2bi - 4b^2i)/(a^4 + 2a^2b^2 + b^4)

Simplifying, we get:

z^2 = (a^4 - b^4 + 2a^2bi)/(a^4 + 2a^2b^2 + b^4)

Now, let's compute z^2 + 1/2z:

z^2 + 1/2z = (a^4 - b^4 + 2a^2bi)/(a^4 + 2a^2b^2 + b^4) + 1/2[(a+bi)/(a-bi)]

To simplify this expression, we need to find a common denominator:

z^2 + 1/2z = (2a^5 - 2a^3b^2 + 3a^4b - 3ab^4 - 2b^5 + 3a^3bi + 3ab^3i)/(2(a^4 + 2a^2b^2 + b^4))

We can see that the imaginary part of z^2 + 1/2z is (3a^3b - 3ab^3)/(2(a^4 + 2a^2b^2 + b^4))

However, we know that a and b are real numbers, so the imaginary part of z^2 + 1/2z is zero.

Therefore, z^2 + 1/2z is a real number.

△CDE∼△PQR. CD=9 m, EC=15 m, PQ=15 m. What is the length of RP?

Answers

Answer:

RP = 25

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{RP}{EC}[/tex] = [tex]\frac{PQ}{CD}[/tex] ( substitute values )

[tex]\frac{RP}{15}[/tex] = [tex]\frac{15}{9}[/tex] ( cross- multiply )

9 RP = 15 × 15 = 225 ( divide both sides by 9 )

RP = 25

If a drug has a concentration of 5.315 mg per 3.743 mL, how many mL are needed to give 4.719 gram of the drug? Round to 1 decimal.

Answers

Answer:

888.4 mL.

Step-by-step explanation:

To solve this problem, we can use the following formula:

Amount of drug (in mg) = concentration (in mg/mL) × volume (in mL)

We are given the concentration of the drug as 5.315 mg per 3.743 mL. To find the volume of the drug needed to give 4.719 g, we need to rearrange the formula to solve for volume:

Volume (in mL) = amount of drug (in mg) ÷ concentration (in mg/mL)

First, we need to convert 4.719 g to mg by multiplying by 1000:

4.719 g × 1000 mg/g = 4719 mg

Now we can substitute the given concentration and the calculated amount of drug into the formula and solve for volume:

Volume (in mL) = 4719 mg ÷ 5.315 mg/mL

Volume (in mL) ≈ 888.5 mL

Therefore, approximately 888.5 mL of the drug are needed to give 4.719 g. Rounded to 1 decimal, the answer is 888.4 mL.

Answers

Roberto needs 4 square yards of fabric to make his costume.

What is improper fraction?

A fraction that has the numerator higher than or equal to the denominator is said to be inappropriate. For instance, the fraction 7/3 is incorrect since 7 is bigger than 3. Mixed numbers, which combine a whole number and a correct fraction, can be created from improper fractions.

Given that, piece of fabric that is 2 2/3 yards long and 1 1/2 yard wide.

Convert the length from a mixed number to an improper fraction:

2 2/3 = (2 x 3 + 2)/3 = 8/3

1 1/2 = 3/2

The area of the rectangle is:

Area = Length x Width

Substituting the values we have:

Area = (8/3) x (3/2) = 4

Hence, Roberto needs 4 square yards of fabric to make his costume.

What is the average rate of change between
the points (17, 5) and (19, --1)?

Answers

The average rate of change between the points (17, 5) and (19, -1) is -3.

What is the average rate of change?

If we have a given function y = f(x) with two known points (a, f(a)) and (b, f(b)), then the average rate of change in that interval [a, b] is:

R = ( f(b) - f(a))/(b - a)

Here we have the two points (17, 5) and (19, -1)

So we have:

a = 17 and f(a) = 5

b = 19 and f(b) = -1

Replacing that in the formula for the average rate of change we will get:

R = (-1 - 5)/(19 - 17)

R = -6/2

R = -3

The average rate of change is -3
