Answer:

Step-by-step explanation:

Average rate of change for a given function is given by

$\frac{f(b)-f(a)}{b-a}$

For our question a is -1 and b is 2.

Now since points (-1,-1) and (2,5) are on the graph given it means

f(-1)=-1 and f(2)= 5

So using the formula and given values we get

Average rate of change = $\frac{f(2)-f(-1)}{2-(-1)}$

= $\frac{5-(-1)}{2-(-1)}$

= $\frac{6}{3}$

Average rate of change = 2

olchik [2.2K]

Answer:

x = 5

Step-by-step explanation:

=(-5-√-75)/2=(-5-5i√ 3 )/2= -2.5000-4.3301i

x =(-5+√-75)/2=(-5+5i√ 3 )/2= -2.5000+4.3301i

x = 5

Click on the graph below to create a quadrilateral with vertices at the following points. (-4,9), (-8,9), (-9,7), (-9, 4)

Shalnov [3]

Given (-4,9) (-8,9),(-9,7,(-9,4)

...

To Find : plot the point and draw quadrilateral

Solution:

(-4,9)

go 4 left of origin and then go 9 up

(-8,9)

go 8 left of origin and then go 8 up

(-9,7)

go 9 left of origin and then go 7 up

(-9,4)

go 9 left of origin and then go join (-4,9) with (-8,9) and (-9,4) 4 up

join (-9,7) with (-8,9) and (-9,4)

Quadrilateral is constructed

Malika bought 7 new pairs of shoes. Each pair of shoes cost the same amount and was discounted by $21.75.

ikadub [295]

Multiply the amount of the discount by pairs of shoes:

21.75 x 7 = 152.25

Add that to the total she spent:

152.25 + 654.50 = 806.75

Divide the total by pairs of shoes:

806.75/7 = $115.25

The answer is C. $115.25

He cost, in millions of dollars, of building a three-story high school in new york state was estimated to be c(x) = 2.1 + 0.12x

ratelena [41]

Given cost function is

c(x) = $2.1 + 0.12x - 0.0001x^2$ (20 ≤ x ≤ 400)

where x is the number of thousands of square feet

total revenue will be $0.2 million dollars per thousand square feet

Revenue is 0.2 millions per thousand square feet. we know x is the number of thousand of square feet

So R(x) = 0.2x

We know Profit = Revenue - Cost

P(x) = R(x) - C(x)

$P(x) = 0.2x - (2.1 + 0.12x - 0.0001x^2)$

$P(x) = 0.2x - 2.1 - 0.12x + 0.0001x^2)$

combine like terms

$P(x) =-2.1 + 0.08x + 0.0001x^2$

Profit function is

$P(x) =0.0001x^2 + 0.08x - 2.1$

Which of the following is the solution set of -21xl <-8

Norma-Jean [14]

Answer:

$x\:>\:4$ or $x\:$

Step-by-step explanation:

The given absolute value inequality is $-2|x|\:$

Divide both sides of the inequality by -2 and reverse the inequality sign:

$|x|\:>\:4$

By the definition of the absolute value function;

Either $x\:>\:4$ or $-x\:>\:4$

Divide through the rightmost inequality by -1 and reverse the sign.

This implies that:

$x\:>\:4$ or $x\:$
