Answer:

The term 27p represents the total cost in dollars of pants

The term 13(p+4) represents the total cost in dollars of shirts

The expression 27p+13(p+4) represents the overall cost in dollars of the shirts and pants Christ buys

Step-by-step explanation:

Disclaimer: if the owner can include the options, I can give a better answer.

We know each pair of pants is $27. Since each pair of pants costs $27, we can say the total cost in dollars of pants is equal to 27*P. For each pair of pants Chris buys, he buys 4 shirts. P+4 is the total number of shirts Chris will buy. The price of these shirts in dollars is $13. So we can assume the total cost in dollars of shirts will be 13(P+4). The total expression is the total amount in dollars Chris spends.

Number of shoes needed to wrap around the equator = 7.57 x10⁷

The length of a size 7 shoe = 1.4 x 10-¹ m

The circumference of the Earth around the equator =  1.06 x 10^7 m

We know that here, the circumference around the equator will be equal to the number of shoes times the length of each shoe.

So to find the number of shoes, we should divide the circumference of the Earth by the length of one shoe.

Hence, number of shoes end-to-end needed to wrap around the equator = 1.06 x 10⁷ / 1.4 x 10-¹

             = 7.57 x10⁷

One of the boards is 30 inches long and the other board is 12 inches longer so it has to be 42 inches long. The sum of the lengths of the two boards is 72 cm and one of the boards is 12 inches longer than the other.

Here,

A board is 72 cm in length and must be cut so that one piece is 12 cm longer than the other piece .

We have to find the leg of each piece.

What is Length, Width and height?

The length, width and  height of an object are the different dimensions in linear units. length is the longest side of a shape, width is the shorter side, and height is the vertical dimension of the shape.

Now,

If you're going to cut the 72 inch board into two pieces, you can call one of the pieces x units long.

And, since the other piece is 12 inches longer than your first piece, its length is x + 12.

And, when you place these two pieces back together, their lengths should add up to be 72 inches.

You can write this last statement about adding the two pieces together to get a 72 inch piece

In equation form as:

x + (x+12) = 72

2x + 12 = 72

To solve this begin by subtracting 12 from both sides;

2x = 60

Now just divide both sides by 2 to find that:

x = 30

So, one of the boards is 30 inches long and the other board is 12 inches longer so it has to be 42 inches long. The sum of the lengths of the two boards is 72 cm and one of the boards is 12 inches longer than the other.

The range of the function is x∈[(-8 ,16)]

It is required to find the  range.

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given:

Since f(x) = -2x + 4  is linear, its limit values correspond to the limits imposed by the domain (in this case x∈[(-6 ,6)]

By put the value of x in the given function we get,

f(-6) = -2(-6) + 4

        =12+4

         =16

f(6) = -2*6 + 4

       =-12+4

        =-8

So the range is -8<x<16.

Therefore, the range of the function is x∈[(-8 ,16)]

Derivatives are essential for solving calculus and differential equation problems then the derivative of this function is [tex]$f^{\prime}(x)=k$[/tex]

The rate of change of a function with respect to a variable in Mathematics. Derivatives are essential for solving calculus and differential equation problems.

Given a traditional unbent position, f(x) = kx + d, where k is the pitch and (0, d) is the y-intercept.

a) Consider our position at two distinct points first:

f(x) = kx + d

f(x + h) = k(x + h) + d = kx + kh + d

Evaluate the derivative, then

[tex]$\lim h \rightarrow x \frac{f(x+h)-f(x)}{h}[/tex]

substitute the values in the above equation, we get

[tex]$&=\lim h \rightarrow x \frac{(k x+k h+d)-(k x+d)}{h} \\[/tex]

simplifying the above equation, we get

[tex]$&=\lim h \rightarrow x \frac{k h}{h} \\[/tex]

[tex]&=\lim h \rightarrow x k \\[/tex]

= k

Therefore, the derivative of this function is [tex]$f^{\prime}(x)=k$[/tex]

Answer:

5.14 minutes

Step-by-step explanation:

4 pages / 7 minutes = 0.57 minutes per page

0.57 minutes/pg * 9 pages = 5.14 minutes

7) (x, TU, TB) = (4, 8, 13)

9) (x, RS, MN) = (8, 41, 41)

11) (AB, BC, AC) = (42, 42, 84)

In this question we have three cases of colinear line segments, each of them can be solved by using definitions from Euclidean geometry and algebraic handling:

Case 7 - TU = 2 · x, UB = 3 · x + 1, TB = 21

TB = TU + UB

21 = 2 · x + 3 · x + 1

21 = 5 · x + 1

5 · x = 20

x = 4

Then, the lengths of each line segment are:

TB = 21

TU = 2 · 4

TU = 8

UB = 3 · 4 + 1

UB = 13

The solutions are (x, TU, TB) = (4, 8, 13).

Case 9 - RS = 3 · x + 17, MN = 7 · x - 15

RS = MN

3 · x + 17 = 7 · x  - 15

4 · x = 32

x = 8

And the lengths of each line segment are:

RS = MN = 41

The solutions are (x, RS, MN) = (8, 41, 41).

Case 11 - AB = 2 · x - 8, BC = x + 17

AB + BC = AC

AB = BC

2 · x - 8 = x + 17

x = 25

And the lengths of each line segment are:

AB = 2 · 25 - 8

AB = 42

BC = AB

BC = 42

AC = 42 + 42

AC = 84

The solutions are (AB, BC, AC) = (42, 42, 84).

Step-by-step explanation:

The area of the region enclosed by the curves y = 7sin x and y = sin(7x) , 0 < x < π is 13.7 square units.

Given the equation of the curves:

y = 7sin x and y = sin(7x)

Now, we have to find the area between the curves .

Area between y = 7sin x and y = sin(7x) ,

   A = ∫[7sin(x) - sin(7x)]dx

⇒ A = [-7cos(x) + 1/7 cos(7x)]

⇒ A = [-7cos + 1/7 cos(7)] - [-7cos(0) + 1/7 cos(0)]

Since cos(π) = -1  ;  cos(7) = -1  ; cos(0) = 1

⇒A = [-7(-1) + 1/7 * (-1)] - [-7 * 1 + 1/7 * 1]

⇒A = 7- 1/7 + 7 - 1/7

Answer:

A)  |x - 1200| = 22

B)  x = 1222,  x = 1178

C)  Minimum = $1,178

    Maximum = $1,222

Step-by-step explanation:

Define the variable:

Given information:

If the artist plans to sell $300 of prints each week, then she plans to sell approx $1200 of prints each month, since there are approximately 4 weeks in each month.

If she is within $22 of her goal, this month then:

⇒ |x - 1200| = 22

To solve an equation containing an absolute value, set the contents of the absolute value equal to both the positive and negative value of the number on the other side of the equation, then solve both equations:

Equation 1

⇒ x - 1200 = 22

⇒ x - 1200 + 1200 = 22 + 1200

⇒ x = 1222

Equation 2

⇒ x - 1200 = -22

⇒ x - 1200 + 1200 = -22 + 1200

⇒ x = 1178
