Answer:

• Mean Slope = -7

• c=0.5

Explanation:

Given the function:

Part A

We want to find the mean slope on the interval [-6, 7].

First, evaluate f(7) and f(-6):

Next, substitute these values into the formula for the mean slope.

The mean slope of the function over the interval [-6,7] is -7.

Part B

Given the function, f(x):

Its derivative, f'(x) will be:

Replace c for x:

Equate f'(c) to the mean slope obtained in part a.

Solve for c:

The value of c that satisfies the mean value theorem is 0.5.

Considering the Set A and B given, Applying inclusion - exclusion principle the number of elements common to both Sets is 10

This is a counting techniques that ensures that elements are not counted twice

It is achieved by the formula:

(A ∪ B) = n(A) + n(B) - n(A ∩ B)  

The information from the question include the following

Set A contains 48 elements

Set B contains 16 elements

The total number elements in either Set A or Set B is 54

Applying inclusion - exclusion principle gives the formula

Set A + Set B - ( Set A ∩ Set B ) = Set A ∪ Set B

substituting the values gives

48 + 16 - ( Set A ∩ Set B ) = 54

48 + 16 - 54 = ( Set A ∩ Set B )

10 = ( Set A ∩ Set B )

( Set A ∩ Set B ) = elements Sets A and B have in common

Therefore the number of the elements common to Sets A and B  is 10

Answer C

Tara needs to sell 20 scarves to break even.

The break-even point is the sales level that the seller must attain to make the total revenue equal to the total costs (fixed and variable).

There is no profit or loss at the break-even point (either in units or dollar values).

Selling price per unit = $18

Product cost per unit = $4

Contribution margin per unit = $14

Fixed cost per month = $280

Estimated production and sales units per month = 80 scarves

Break-even sales units = fixed costs/contribution margin per unit

= 20 ($280/$14)

Check:

Total revenue at 20 units = $360 (20 x $18)

Total costs at 20 units = $360 ($280 + $4 x 20)

Thus, for Tara to break even, she needs to sell 20 scarves per month.

Answer:

They are parallel to each other

Explanation:

Two lines are parallel if they have the same slope.

Additionally, in an equation with the following form:

y = mx + b

The number m beside the x, is the slope

So, in this case, both equations have a 3 besides the x, then, they are parallels

Answer:

(f o g)(x) = 8x³ + 2x - 6

(g o f)(x) = 2x³ + 2x - 12

Step-by-step explanation:

f(x) = x³ + x - 6; g(x) = 2x

(f o g)(x) = f(g(x))

f(g(x)) = (2x)³ + (2x) - 6

f(g(x)) = 8x³ + 2x - 6

(g o f) = g(f(x))

g(f(x)) = 2(x³ + x - 6)

g(f(x)) = 2x³ + 2x - 12

After 15 weeks Milo's weight is 39 pounds.

According to the question,

We have the following information:

Weight of Milo = 11 pounds

Milo gained weight at the rate of 2 pounds per week.

So, we have the following progression:

11, 13, 15, ....

Now, we will subtract the previous term from the next term to check whether it is an arithmetic progression or not.

15-13 = 2

13-11 = 2

So, it is an A.P.

We know that following formula is used to find the nth term:

an = a+(n-1)d where a is the first term, n is the number of term and d is the common difference

We have weight of Milo as 39 pounds.

11+(n-1)2 = 39

11+2n-2 = 29

2n+9 = 39

2n = 39-9

2n = 30

n = 30/2

n = 15

Hence, it will take 15 weeks to reach Milo's weight at 39 pounds.

To answer this question, we need to use the next formula for simple interest:

Where:

FV is the future value we need to find (in this case).

PV is the present value, that is, $400 (in this case).

i is the interest rate. In this case, we have 8% (0.08).

n is the number of periods (n = 3, in this case).

Then, we have:

That is, the FV is $496. Therefore, the simple interest is $(496-400 = 96).

Thus, the amount of simple interest that $400 would earn at 8% per year by the end of 3 years is $96 (option A).

In other words, the result can be obtained also if we have is $400 * (0.08)*3 = $96.

Here, we want to get the measure of the angle marked AWL

The measure of this angle is simply half the measure of the big arc WHA

Mathematically, we have the measure of the angle as:

Apply trigonometric functions:

Cos a = adjacent side / hypotenuse

Where:

a = angle = 59°

adjacent side = 34

Hypotenuse = x

Replacing:

Cos 59 = 34 / x

Solve for x:

x = 34 / cos 59

x = 66
