Answer 2

Answer:

Domain:  all real numbers x except x = -4

[tex]\textsf{End behaviour}: \quad f(x) \rightarrow - \infty \; \textsf{as} \; x \rightarrow -4^{-}, \;f(x) \rightarrow \infty \; \textsf{as} \; x \rightarrow -4^{+}[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=\dfrac{7}{x+4}[/tex]

The domain of a function is the set of all possible input values (x-values).

When the denominator of a rational function is zero, the function is undefined.

To find the value(s) of x for which the function is undefined, set the denominator to zero and solve for x:

[tex]\implies x+4=0[/tex]

[tex]\implies x+4-4=-4[/tex]

[tex]\implies x=-4[/tex]

Therefore, the domain of the given function is:

all real numbers x except x = -4

The vertical asymptote(s) of a rational function are the values of x for which the denominator is zero.

Therefore, there is a vertical asymptote at x = -4.

As x gets very close to x = -4 from the negative side, the function approaches -∞ because the denominator will be an extremely small negative number.

As x gets very close to x = -4 from the positive side, the function approaches ∞ because the denominator will be an extremely small positive number.

Therefore, the behaviour of the function near the excluded x-value is:

[tex]f(x) \rightarrow - \infty \; \textsf{as} \; x \rightarrow -4^{-}, \;f(x) \rightarrow \infty \; \textsf{as} \; x \rightarrow -4^{+}[/tex]

Which equation represents the line that passes through the point (5,7) and is parallel to the graph of y=2/3x-7?

Answers

The equation of a line that passes through point (5,7) and parallel to the graph of y = 2/3x - 7 is y = (2/3)x + 11/3

What is the equation of line that passes through the point (5,7) and is parallel to the line y = 2/3x - 7?

The point-slope formula is expressed as

y - y₁ = m( x - x₁ )

Where m is slope.

Given the equation of the graph  y = (2/3)x - 7

Using the slope intercept form where m is slope.

y = mx + b

y = (2/3)x - 7

Slope of the graph will be;

Slope m = 2/3

Next, find the line parallel to the graph and which passes through the point (5,7).

Using the point slope formula

y - y₁ = m( x - x₁ )

Plug in the slope and point.

y - 7 = (2/3)( x - 5 )

Solve for y

y - 7 = (2/3)x - 10/3

y = (2/3)x - 10/3 + 7

y = (2/3)x + 11/3

Therefore, the equation of line parallel to the graph is y = (2/3)x + 11/3.

The length of the building on the scale drawing is found as 16 centimeters.

Describe the term scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a specific widths is known as a scale factor (bigger or smaller).Scale factor ratios can be written as a colon, 1:2, or as a fraction, 12. A ratio calculates the difference between two values.However, that ratio isn't a scale factor, thus you could not build a ratio for left-handed pupils to all students.

For the given data in the question-

Dimensions of the building;

Height of 125 meter length of 80 meters.

Dimensions of the drawing of the building;

height is 25 centimetersLet the length be 'x'.

Thus, taking ratios of Height to length

125/80 = 25/x

On simplification;

x = 80 x 25 / 125

x = 16

Thus, the length of building on the scale drawing is found as 16 centimeters.

Write a quadratic function in standard form whose graph has a vertex of (2, 6) and passes through the point (4, 10) .

Answers

A quadratic function in standard form is of the form y = ax^2 + bx + c, where a, b, and c are constants. The vertex of the graph of a quadratic function is at the point (h, k), where h is the x-coordinate of the vertex and k is the y-coordinate of the vertex.

To write a quadratic function in standard form with a vertex of (2, 6) and that passes through the point (4, 10), we can first use the coordinates of the vertex to determine the values of h and k. We know that h = 2 and k = 6, so we can substitute these values into the formula for the vertex to find the value of a:

k = a(h^2) + bh + c
6 = a(2^2) + b(2) + c
6 = 4a + 2b + c

We can then use the coordinates of the point (4, 10) to find the value of b:

10 = a(4^2) + b(4) + c
10 = 16a + 4b + c

Solving the system of equations formed by these two equations, we find that a = -1, b = 6, and c = 4. Therefore, the quadratic function in standard form whose graph has a vertex of (2, 6) and passes through the point (4, 10) is y = -x^2 + 6x + 4.

Jocelyn estimate that a piece of wood measure 5.5 cm . If it actually measure 5.62 cm, what is the percent error of Jocelyn's estimate

Answers

The Jocelyn estimate's percent error is 2.181 centimeters..

What is percent error ?

Percent error calculates the difference between an estimate and a right number and expresses it as a percentage. Analysts can use this statistic to determine how big the mistake is in relation to the actual number. It is also referred to as % error and percentage error.

There are three steps to determining the % error:

1. Determine the error, which is the estimated value minus the actual value.

2. Multiply by the accurate value.

3. In order to create a percentage, multiply by 100.

Given information:

The size of a piece of wood (Exact value)= 5.5 cm

if it really does measure(Approximate value)=5.62 cm

percentage error={(approximate value-exact value)/exact value}×100

percentage error = ((5.62-5.5)/5.5)×100

percentage error = 2.181cm

Consequently, 2.181cm is the Jocelyn estimate's percent error.

in groups of 10, he has 3 left over. When he
arranges them in groups of 9, he has 5 left
over. If he arranges them in groups of 8, how
many will he have left over?

Answers

Answer:

117$.

Step-by-step explanation:

Let $x$ represent the number of cards in Wei Jing's collection. We are given that $70 \leq x \leq 150$. We are also given that $x \equiv 3 \pmod{10}$ and $x \equiv 5 \pmod{9}$. Since $x \equiv 3 \pmod{10}$, $x - 3$ is divisible by 10. Since $x \equiv 5 \pmod{9}$, $x - 5$ is divisible by 9. The least common multiple of 10 and 9 is $90$, so $(x - 3) - 90$ is divisible by 90 and $(x - 5) - 90$ is divisible by 90. Adding these equations gives us $2x - 98$ is divisible by 90. Dividing both sides by 2 gives us $x - 49$ is divisible by 45. Since $70 \leq x \leq 150$, the only solution for $x$ is $x = 117$.

The measure of the exterior angle is 60°.

What is the Exterior Angle Theorem?

If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.

If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.

We have,

interior angles:

∠ABC = z + 10

∠BAC = 4z

Exterior angle:

∠ACB = z + 50

Exterior Angle Theorem:

The measure of exterior angle = Sum of two opposite interior angles’ measure.

According to the Exterior Angle property of a triangle theorem, the sum of measures of ∠ABC and ∠BAC would be equal to the exterior angle ∠ACB.

∴ ∠ABC + ∠BAC =  ∠ACB

  z + 10 + 4z = z + 50

5z = z + 40

z = 40/4

∴  z = 10

so, the value of the z is 10.

exterior angle:

∠ACB = 10 + 50 =60

Work out the bearing of C from A

Answers

The bearing of C from A is 60° South.

How does one calculate bearing from A to B?

The bearing from A to B can be determined using interior angle if the bearing from B to A is known. Use the fact that angles in a full turn add up to 360° to determine the bearing of A to B, then subtract the bearing of B to A from 180° to determine the missing interior angle. For instance, B is 050° from A in terms of bearing.

When AN elongates the angle will be 180°

Then the angle between A and C:

35° + 85° + x = 180°

120° + x = 180°

x = 180° - 120°

x = 60°

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, A linear equation y = (1/3)x + 2.

Now to graph the equation we'll simply put some arbitrary values of x which will correspond to some values of y and plot them then we'll join them with a straightedge.

When x = 3, y = 3 ⇒ (3, 3).

When x = - 3, y = 1 ⇒( -3, 1).

What is the approximate perimeter of this triangle?

Answers

Answer:

163.6 in

---------------------------

Given:

a = 56 in,m∠A = 55°.

Find the missing sides:

56/b = tan 55° ⇒ b = 56 / tan 55° = 39.21 in,56/c = sin 55° ⇒ c = 56 / sin 55° = 68.36 in.

Perimeter is:

56 + 68.36 + 39.21 = 163.57 ≈ 163.6 in

a) A discrete random variable is a variable that can take only a countable number of distinct values, such as 0, 1, 2, 3, 4, and so on.

b) Examples of discrete random variables are the number of children in a family, the number of people who go to the cinema on Friday nights, etc.

c) E(x) = 1/p

Discrete Random Variable:

A discrete random variable can be defined as a type of variable whose value depends on the numerical outcome of some random phenomenon. Also called a random variable. Discrete random variables are always easily countable integers. A probability mass function is used to describe the probability distribution of a discrete random variable.

Discrete random variables are used to quantify the results of random experiments. A discrete random variable takes on an infinite number of possible outcomes. In general, discrete random variables can be counted as 0, 1, 2, 3, 4, ...

Geometric Distribution :

The geometric variate is the variate that specifies the number of consecutive failures before the first success in Bernoulli trials. The probability of success of a Bernoulli trial is given by p and the probability of failure is 1 - p.

The Geometric Random Variable can be written as X ~ G(p).

The probability mass function is P(X = x) = (1  - p)ˣ⁻¹ p

An SRS of 20 third grade children is selected in Chicago and each is given a test to measure their reading ability. We are interested in a 90% confidence interval for the population mean score. In the sample, the mean score is 64 points, and the standard deviation is 12 points. The margin of error associated with the confidence interval is
O 4.64 points.
O 5.62 points.
O 2.68 points.

Answers

The margin or error associated with the confidence interval is 5.62 points

The sample size of the third grade children = 20

The confidence interval for the population mean score  = 90%

The mean score = 64 points

The standard deviation = 12 points

The degree of freedom = The sample size - 1

= 20 - 1

= 19

The critical value of t at degree of freedom 19 = ±2.093

The margin error = Critical value of t × [tex]\frac{s}{\sqrt{n} }[/tex]

Substitute the values in the equations

The margin error = 2.093 × [tex]\frac{12}{\sqrt{20} }[/tex]

= 2.093 × 2.68

= 5.62 points

Therefore, the margin error is 5.62 points

David says that a triangle with side measures 9 cm, 12 cm, and 17 cm is a right triangle. Susie says it is not. Who is correct? Explain
your reasoning.
12 cm
17 cm
9 cm

Answers

Answer: Susie is correct.

Step-by-step explanation:

Susie is correct, because the Pythagorean theorem does not work on this triangle. Since the Pythagorean theorem only works on right triangles, we can conclude that Susie is correct, and that this triangle is NOT a right triangle.

a²+b² = c²

a = 9

b = 12

c = 17

9² + 12² = 17²

==> 81 + 144 = 289

==> 225 = 289, This is not true

Therefore this triangle is not a right triangle.
