if the intrest earned on a account after 2 years is $15, how much would it be after 10 year? Why?
The amount after 10 years with a principal of $100 and interest rate of 7% compounded annually would be $196.72.
The term "amount" refers to the quantity or total of something. It is a general term used to describe the measure or magnitude of a particular quantity. The specific context in which "amount" is used determines what it is referring to.
For example:
In finance and accounting, "amount" often refers to a monetary value or sum of money. It can represent the total of a bill, an invoice, a balance, or a transaction.
In mathematics, "amount" can be used to describe the result of a calculation or the value of a quantity. For instance, the amount of money in a bank account after a series of deposits and withdrawals.
In everyday language, "amount" can refer to a general quantity or measure of something, such as the amount of food in a recipe, the amount of time spent on a task, or the amount of rainfall in a particular area.
Given that the interest earned on an account after two years is $15. We need to find out how much it would be after 10 years, assuming the interest rate is constant over time.
The formula for compound interest is given by [tex]A= P(1+\frac{r}{n} )^{nt}[/tex]
Where,
A = final amount,
P = principal amount,
r = annual interest rate (as a decimal),
n = number of times the interest is compounded per year, and t = time in years.
Substituting the given values in the formula, we get A = P (1 + r/n)^(nt)
Since we are not given the principal amount, we can assume it to be any value. Let us assume the principal amount to be $100 for simplicity. Therefore, P = $100After two years, the interest earned is $15.
Therefore, the final amount after two years would be $100 + $15 = $115.t = 2 years
[tex]A= P(1+\frac{r}{n} )^{nt}[/tex]
115 = 100(1 + r/1)²
115/100 = (1 + r)²
1.15 = (1 + r)²
Taking square root on both sides, we get1.07 = 1 + rr = 0.07. Thus, the annual interest rate is 7%.
Now, substituting the given values in the formula, [tex]A= P(1+\frac{r}{n} )^{nt}[/tex]
We get, A = 100(1 + 0.07/1)¹⁰ˣ¹
A = $196.72
Therefore, the amount after 10 years with a principal of $100 and interest rate of 7% compounded annually would be $196.72.

A man sets out to travel from A to C via B. From A he travels 8km on a bearing N30°E to B. From B, he travels a further 6km due East. Calculate how far C is (i) North of A (ii) east of A?
He travels: (i) C is 4 km north of A. (ii) C is 6 km east of A.
How to Calculate how far C is (i) North of A (ii) east of A(i) North of A:
The northward component from A to B is 8 km on a bearing of N30°E. To find the northward distance, we can use trigonometry. Since the bearing is N30°E, we can split it into two right-angled triangles: one facing north and one facing east.
In the northward triangle:
Opposite side = 8 km * sin(30°)
Opposite side = 8 km * 0.5
Opposite side = 4 km
Therefore, C is 4 km north of A.
(ii) East of A:
The eastward component from B to C is 6 km due East. Since this distance is directly east, it does not change the eastward position of C relative to A. Therefore, C is 6 km east of A.

Julia writes 2 fractions with the same denominator that have numerators 8 and 2 . What could the denomination be if the sum is less than 1.?Equal to 1? Greater than 1?
If the sum of the fractions is less than 1, the denominator could be any number greater than 10. If the sum is equal to 1, the denominator must be 10. If the sum is greater than 1, the denominator must be less than 10.
To find a denominator that satisfies the given conditions, we can consider the fractions with numerators 8 and 2. If the sum of these fractions is less than 1, the denominator could be any number greater than 10. If the sum is equal to 1, the denominator must be 10. If the sum is greater than 1, the denominator must be less than 10.
To determine the possible denominators that satisfy the conditions, we need to consider the given numerators of 8 and 2. Since the fractions have the same denominator, let's denote it as 'd'. The fractions can be written as 8/d and 2/d.
If the sum of these fractions is less than 1, we have:
8/d + 2/d < 1
Combining the fractions, we get:
(8 + 2)/d < 1
Simplifying, we have:
10/d < 1
To satisfy this inequality, the denominator 'd' can be any number greater than 10. For example, if we choose d = 11, the fractions become 8/11 and 2/11, and their sum is 10/11, which is less than 1.
If the sum of the fractions is equal to 1, we have:
8/d + 2/d = 1
Combining the fractions, we get:
10/d = 1
Solving for 'd', we find that the denominator must be 10. For example, if we choose d = 10, the fractions become 8/10 and 2/10, and their sum is 10/10, which is equal to 1.
If the sum of the fractions is greater than 1, we have:
8/d + 2/d > 1
Combining the fractions, we get:
10/d > 1
To satisfy this inequality, the denominator 'd' must be less than 10. For example, if we choose d = 9, the fractions become 8/9 and 2/9, and their sum is 10/9, which is greater than 1.
In summary, if the sum of the fractions is less than 1, the denominator could be any number greater than 10. If the sum is equal to 1, the denominator must be 10. If the sum is greater than 1, the denominator must be less than 10.

What is the quotient of (x3 – 3x2 5x – 3) ÷ (x – 1)?.
The quotient of (x³ – 3x² + 5x – 3) ÷ (x – 1) can be found by using long division. First, we place the dividend, which is x³ – 3x² + 5x – 3, inside the division symbol. Then, we divide the first term of the dividend, which is x³, by the divisor, which is x – 1. This gives us x² as our first term of the quotient.
We then multiply x² by the divisor, which gives us x³ – x². We subtract this from the dividend to get -2x² + 5x – 3.We then bring down the next term of the dividend, which is 0x² + 5x. We repeat the process of dividing, multiplying, subtracting, and bringing down until we reach the end of the dividend. This gives us the quotient as x² + 2x + 5 and a remainder of 2x – 3.We have a polynomial division, x³ – 3x² + 5x – 3 ÷ x – 1. Using polynomial division, we can find the quotient and remainder when dividing one polynomial by another. Let's go through the process of polynomial division step-by-step:
We will first divide the x³ by x, which gives us x². We will then multiply x² by the divisor x – 1, which gives us x³ – x². We will subtract this from the original polynomial, x³ – 3x² + 5x – 3 – (x³ – x²) = -2x² + 5x – 3.Next, we will divide -2x² by x, which gives us -2x. We will then multiply -2x by the divisor x – 1, which gives us -2x² + 2x. We will subtract this from the polynomial we obtained in the previous step, -2x² + 5x – 3 – (-2x² + 2x) = 3x – 3.Finally, we will divide 3x by x, which gives us 3. We will then multiply 3 by the divisor x – 1, which gives us 3x – 3. We will subtract this from the polynomial we obtained in the previous step, 3x – 3 – (3x – 3) = 0.Remember that the quotient of a polynomial division is the polynomial that we obtain after performing all the steps of polynomial division. Therefore, the quotient in this case is x² – 2x + 3. The remainder is 0, which means that the polynomial x³ – 3x² + 5x – 3 is evenly divisible by x – 1.
To conclude, the quotient of (x³ – 3x² + 5x – 3) ÷ (x – 1) is x² – 2x + 3. The remainder is 0, which means that the polynomial x³ – 3x² + 5x – 3 is evenly divisible by x – 1.

The given equation is I = -2OD where I is the intensity of light, O is the aperture of the lens and D is the distance between the lens and the object. This equation is known as the Inverse Square Law of Light.
The equation states that the intensity of light decreases as the square of the distance between the object and the ens increases. This means that if we double the distance between the object and the lens, the intensity of light becomes 1/4th of its original value.Similarly, if we triple the distance between the object and the lens, the intensity of light becomes 1/9th of its original value. This law is applicable to all types of light sources, including natural light sources like the sun and artificial light sources like bulbs.One practical application of this law is in photography. If a photographer wants to capture an image of a subject that is far away, they need to use a lens with a larger aperture to let in more light. This will ensure that the image is bright and clear even when the distance between the subject and the camera is large.Similarly, if a photographer wants to capture an image of a subject that is close to the camera, they need to use a lens with a smaller aperture to reduce the amount of light that enters the camera. This will prevent the image from being overexposed and washed out.Overall, the Inverse Square Law of Light is an important principle that governs the behavior of light in various applications, including photography, cinematography, and physics.For such more question on Square Law

e = 1200 and a whale is 3/4 of this weight so:
1200 / 4 = 400 which means 1/4 of the weight is 400
Multiply by 4 and get the total weight of 1600
w = 1600
g = 1600(1/8)
g = 200
200 is 5/6 of the weight of 12 deer so each 1/6 is 40
multiply 6 * 40

A coin is tossed 25 times. The result is that there are 9 "heads" and 16 "tails". Consider the model that the number of "heads" follows a binomial distribution with the size equal to 25 and the probability of success equal to 0.5. That is, the probability of k
The probability of k "heads" is given by:P (k) = C(25, k) (0.5)^(k) (0.5)^(25-k)where C(25, k) = 25!/[k!(25-k)!].The result of a coin being tossed 25 times shows 9 "heads" and 16 "tails."
The probability of having 9 "heads" in 25 coin tosses is given by:P(9) = C(25, 9) (0.5)^(9) (0.5)^(25-9) = 0.097.While the probability of having 16 "tails" in 25 coin tosses is given by:P(16) = C(25, 16) (0.5)^(16) (0.5)^(25-16) = 0.098.Both the probabilities, P(9) and P(16), are nearly the same.
This means that the occurrence of 9 "heads" and 16 "tails" is equally likely. Therefore, it is not at all surprising to get 9 "heads" and 16 "tails" in 25 coin tosses, even if the coin is unbiased.

Tommy walks 2 miles to school each morning. During his walk he sees billboards every 1/5 of a mile. How many billboards does he see each morning?
Tommy walks 2 miles to school each morning, and he sees a billboard every 1/5 of a mile.
To find out how many billboards he sees, we can divide the total distance he walks (2 miles) by the distance between each billboard (1/5 of a mile).
Number of billboards = Total distance / Distance between billboards
= 2 miles / (1/5 mile)
= 2 miles * (5/1)
= 10 billboards
Therefore, Tommy sees 10 billboards each morning.

A total of 500 voters are randomly selected in a certain precinct and asked whether they plan to vote for the Democratic incumbent or the Republican challenger. Of the 500 surveyed, 305 said they would vote for the Democratic incumbent. Using the 0. 99 level of confidence, what are the confidence limits for the proportion that plan to vote for the Democratic incumbent
The confidence limits for the proportion of voters planning to vote for the Democratic incumbent are approximately 0.558 and 0.662.
We have,
To find the confidence limits for the proportion of voters planning to vote for the Democratic incumbent, we can use the formula for a confidence interval for a proportion.
Given:
Sample size (n) = 500
Number of respondents voting for the Democratic incumbent (x) = 305
Confidence level (1 - α) = 0.99
First, we calculate the sample proportion (p-hat):
p-hat = x / n = 305 / 500 = 0.61
Next, we calculate the standard error (SE) of the proportion:
SE = √((p-hat x (1 - p-hat)) / n)
= √((0.61 x (1 - 0.61)) / 500)
= 0.020
Using the z-score corresponding to a 0.99 confidence level, which is approximately 2.576, we can calculate the margin of error (ME):
ME = z x SE = 2.576 x 0.020 = 0.052
Finally, we can calculate the confidence interval:
Confidence Interval = p-hat ± ME
Confidence Interval = 0.61 ± 0.052
Therefore,
The confidence limits for the proportion of voters planning to vote for the Democratic incumbent are approximately 0.558 and 0.662.

If G is the incenter of AABC, find each measure.
Therefore, the measures of the angles AGB, BGC, and AGC are given by:$$m\angle AGB=\frac{180^\circ}{\pi}\cdot \arctan\frac{z}{x+y+z}$$$$m\angle BGC=\frac{180^\circ}{\pi}\cdot \arctan\frac{y}{z}$$$$m\angle AGC=\frac{180^\circ}{\pi}\cdot \arctan\frac{x}{z}$$Thus, the solution is obtained.
Given that G is the incenter of the triangle AABC.The incenter of a triangle is the intersection point of the angle bisectors of the triangle's three angles.We have to find the measure of the angles AGB, BGC, and AGC.
Solution:Let us consider the figure below: [asy]
pair A,B,C,I; A=(-6,-3); B=(4,-3); C=(0,6); draw(A--B--C--A); I=incenter(A,B,C); draw(incircle(A,B,C)); draw(A--I--B); draw(I--C); dot(A); dot(B); dot(C); dot(I); label("$A$",A,WSW); label("$B$",B,ERS); label("$C$",C,N); label("$G$",I,NW); label("$a$",(B+C)/2,E); label("$b$",(A+C)/2,NW); label("$c$",(A+B)/2,SW); label("$x$",(I+B)/2,W); label("$y$",(I+C)/2,NE); label("$z$",(A+I)/2,NW); [/asy]
We can use the angle bisector theorem to determine the measure of the angles AGB, BGC, and AGC.Let $AB=c$, $AC=b$, and $BC=a$. Let $x$, $y$, and $z$ be the lengths of the line segments as shown in the figure above.
By the angle bisector theorem, we know that:$$\frac{AG}{BG}=\frac{b}{a}$$$$\frac{BG}{CG}=\frac{c}{b}$$$$\frac{CG}{AG}=\frac{a}{c}$$
Multiplying these three equations, we get:$$\frac{AG}{BG}\cdot \frac{BG}{CG}\cdot \frac{CG}{AG}=\frac{b}{a}\cdot \frac{c}{b}\cdot \frac{a}{c}=1$$
Thus, we have:$$\frac{x}{z}\cdot \frac{z}{y}\cdot \frac{y}{x}=1$$$$\Rightarrow \frac{x}{y}=\frac{z}{x+y+z}$$
Therefore:$$m\angle AGB=\frac{180^\circ}{\pi}\cdot \arctan\frac{x}{y}=\frac{180^\circ}{\pi}\cdot \arctan\frac{z}{x+y+z}$$
Similarly, we can show that:$$m\angle BGC=\frac{180^\circ}{\pi}\cdot \arctan\frac{y}{z}$$$$m\angle AGC=\frac{180^\circ}{\pi}\cdot \arctan\frac{x}{z}$$.

If x food calories is equivalent to k kilojoules, what represents the relationship between x and k?
If x is doubled, then k will also be doubled.
If x food calories is equivalent to k kilojoules, then the relationship between x and k can be represented by the conversion factor. The conversion factor used to convert food calories to kilojoules is 4.184. This means that one food calorie is equal to 4.184 kilojoules. The relationship between x and k can be expressed mathematically as: kJ = x kcal × 4.184 The conversion factor can also be used in the opposite direction, that is, to convert kilojoules to food calories.
In this case, the relationship between x and k would be expressed as: x kcal = kJ ÷ 4.184In both cases, the relationship between x and k is a direct proportionality, meaning that as the value of x increases, the value of k also increases. Therefore, if x is doubled, then k will also be doubled.

Right triangle, the hypotenuse is the longest side and is opposite the right angle. The length of the hypotenuse of the right triangle is approximately 31.6 in.
In a right triangle, the hypotenuse is the longest side and is opposite the right angle. To find the length of the hypotenuse, we can use the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the two legs.
Let's denote the length of the legs as a = 18 in and b = 26 in. The Pythagorean theorem can be written as:
c^2 = a^2 + b^2
Substituting the values, we have:
c^2 = 18^2 + 26^2
= 324 + 676
= 1000
Taking the square root of both sides, we find:
c = √1000
≈ 31.6
Therefore, the length of the hypotenuse is approximately 31.6 in, rounded to the nearest tenth.
