The reason is because 1 ft = 12 in, (1 ft)2 = (12 in)2 = 144 in2.

Answer:

? = 16

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan ? = opp side / adj

tan ? = 13 / 46

Taking the inverse tan of each side

tan ^ -1 ( tan ? ) = tan ^-1 ( 13/46)

? = 15.78075

To the nearest degree

? = 16

Answer:

Let x be the number of miles Clara put on her car in June.

We are given that Clara put 860 miles on her car in May, so we can write:

Number of miles Clara put on her car in June = 2(860) - 28 (since she put 28 less than twice the number of miles on her car than she did in May)

Simplifying this expression, we get:

Number of miles Clara put on her car in June = 1,692

Therefore, Clara put 1,692 miles on her car in June.

Answer:    increase 96.74%

Step-by-step explanation:

860 x 2 - 28 = 1692

1692 = 860 = 1.9674

( 1.9674 - 1 ) x 100 % = 96.74 %

By the Comparison Test, the series Σ f(n)(2m^3 - 1) also converges, regardless of the rule for f.

The given series is Σ f(n)(2m^3 - 1), n = 1 to infinity. To show that it converges, we can use the Comparison Test.

Consider the series Σ |f(n)(2m^3 - 1)|. Since 0 < f(x) for all x, we have |f(n)| = f(n). Thus, the series becomes Σ f(n)(2m^3).

Now, let's compare this series to Σ 2m^3. Since f(n) > 0 for all n, we know that f(n)(2m^3) ≤ 2m^3 for all n. Thus, Σ f(n)(2m^3) ≤ Σ 2m^3.

The series Σ 2m^3 is a convergent p-series with p = 3 (since 3 > 1). Therefore, by the Comparison Test, the series Σ f(n)(2m^3 - 1) also converges, regardless of the rule for f.

Step-by-step explanation:

avg rate of change = \(\frac{f(b)-f(a)}{b-a}\)

\(\frac{f(3)-f(-1)}{3-(-1)}\)

1. find your y-values.

we are given the x values from the interval [-1,3]. Plug each into the equation to get the y-value of the coordinates.

\(f(-1)=4(-1)^2+3(-1)-4\\f(-1)=4(1)-3-4\\f(-1)=-3\\\)

Answer:

$600

Step-by-step explanation:

We know

2/5 = $240

1/5 = $120

5/5 - 2/5 = 3/5

So, we need to find the 3/5 missing

1/5 = $120

3/5 = $360

So, we add both numbers to find the trip cost

240 + 360 = $600

So, the trip costs $600

In an orthic triangle, triangle AEF, triangle BFD, and triangle CDE are each similar to triangle ABC.

An orthic triangle is formed by constructing perpendiculars from the vertices of a given triangle to the opposite sides. In this case, we have triangle ABC, and by constructing perpendiculars from the vertices A, B, and C to the opposite sides, we obtain triangle AEF, triangle BFD, and triangle CDE.

To show that triangle AEF, triangle BFD, and triangle CDE are each similar to triangle ABC, we need to demonstrate that their corresponding angles are congruent and their corresponding sides are proportional.

Since triangle ABC and its orthic triangles share the same vertices, their corresponding angles are congruent. The perpendiculars drawn from the vertices of triangle ABC to the opposite sides create right angles, ensuring that the corresponding angles in the orthic triangles are also right angles.

Regarding the sides, the perpendiculars from the vertices of triangle ABC divide the sides into segments. By the properties of perpendicular lines, these segments form similar triangles with triangle ABC. Therefore, the corresponding sides of triangle AEF, triangle BFD, and triangle CDE are proportional to the sides of triangle ABC.

By establishing congruent angles and proportional sides, we can conclude that triangle AEF, triangle BFD, and triangle CDE are each similar to triangle ABC.

The  variable x represent the length of rectangle.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Perimeter= 64 units

let the length be x.

So, width = x - 3

So, Perimeter of rectangle = 2 ( l + w)

64 = 2( x+ x -3)

32 = 2x -3

29= 2x

x= 29/2

\(4x^2 - 38x + 34 = 0\) ; This is a quadratic equation that can be solved using the quadratic formula. Once we solve for x, we can find the width of the border.

Let's assume that the width of the border around the text is x inches. Then the dimensions of the rectangle including the border will be:

Length = 11 inches

Width = 8 inches

The dimensions of the rectangle containing only the text will be:

Length = 11 - 2x inches (because there are two borders, one on each side)

Width = 8 - 2x inches (because there are two borders, one at the top and one at the bottom)

The area of the rectangle containing only the text will be:

Area = (11 - 2x) × (8 - 2x)

We know that the area of the rectangle containing only the text is 54 square inches. So we can set up the equation:

(11 - 2x) × (8 - 2x) = 54

Expanding the left-hand side of the equation, we get:

\(88 - 38x + 4x^2 = 54\)

Rearranging and simplifying, we get:

\(4x^2 - 38x + 34 = 0\)

This is a quadratic equation that can be solved using the quadratic formula. Once we solve for x, we can find the width of the border.

The class that lost the most pencils overall based on the data displayed is D. Mr. Johnson's class; it has a wide spread in the data

The answer is Mr. Johnson's class. The median is the middle value in a set of data. In Mr. Johnson's class, the median is 11 pencils. This means that half of the students in his class lost 11 or fewer pencils, and half of the students lost 11 or more pencils.

In Mr. Simpson's class, the median is 14.5 pencils. This means that half of the students in his class lost 14.5 or fewer pencils, and half of the students lost 14.5 or more pencils.

Since the median for Mr. Johnson's class is lower than the median for Mr. Simpson's class, we can conclude that Mr. Johnson's class lost more pencils overall.

The given question is incomplete and lacks specific information or context. It mentions a mathematics portion of a test and a score requirement of 25 or higher, assuming the test scores are normally distributed. However, there is no clear question or task stated. To provide a comprehensive answer, it is necessary to have a specific question or prompt related to the given information.

Without a specific question or task, it is difficult to provide a detailed explanation or analysis. However, based on the limited information provided, it seems that the question might be asking for the probability or percentage of students scoring 25 or higher on the mathematics portion of the test, assuming a normal distribution of test scores. To calculate this probability, additional information is needed, such as the mean and standard deviation of the test scores or a z-score table.

Using the mean and standard deviation, one could calculate the z-score for a score of 25 and then determine the corresponding probability from the z-score table. The z-score represents the number of standard deviations a particular score is from the mean. By looking up the z-score in the table, one can find the corresponding probability or percentage.

However, since the question lacks specific information or context, it is not possible to provide a more detailed or accurate answer.

The x - intercept  of g(h(x)) is, 1/9.

What are linear functions?

Two separate but related concepts are referred to as linear functions in mathematics: A polynomial function of degree 0 or 1 is referred to as a linear function in calculus and related fields if its graph is a straight line.

Let g(x) and h(x) are linear functions.

We have to find the x - intercept of g(h(x)).

Let g(x) and h(x) are linear functions so

g(x) = ax + d and g(x) = cx + e

g(-6) = a(-6) + d

   -11 = -6a + d                   ..(1)

g(-4) = a(-4) + d

   -7 = -4a + d                   ..(2)

Subtract equation (1) and (2)

-11 - (-7) = -6a + d - (-4a + d)

  -1 + 7 = -6a + d + 4a - d

       6 = -2a

       a = -3

Plug a = -3 in equation (1)

11 = -6(-3) + d

11 = 18 + d

d = 11 - 18

d = -7

⇒ g(x) = -3x - 7

Now h(x) = cx + e

h(-6) = c(-6) + e

16 = -6c + e                     ..(3)

h(-4) = c(-4) + e

10 = -4c + e               ..(4)

Subtract question (3) and (4)

16 - 10 = -6c + e - (-4c + e)

       6 = -6c + e + 4c - e

       6 = -2c

       c = -3

Plug c = -3 in equation (3)

16 = -6(-3) + e

16 = 18 + e

e = 16 - 18

e = -2

⇒ h(x) = -3x - 2

Now,

g(h(x)) = -3(h(x) - 7

           = -3(-3x - 2) - 7

           = 9x + 6 - 7

           = 9x - 1

      9x = 1

        x = 1/9

Therefore, the x - intercept of g(h(x)) is 1/9.
