Answer:

The rate of change for the given function is 6.

Step-by-step explanation:

Given function is:

y = x^2+3x-2

The interval on which we have to find the rate of change is:

1≤x≤2

Here

a = 1

b = 2

We have to find the values of function on both points

Putting 1 in place of input (x)

y_a= (1)^2+3(1)-2\\= 1+3-2\\=2

Putting x = 2

y_b = (2)^2+3(2)-2\\= 4+6-2\\=8

The rate of change is calculated by using the following formula

Rate\ of\ change = \frac{y_b-y_a}{b-a}\\=\frac{8-2}{2-1}\\= \frac{6}{1}\\=6

Hence,

The rate of change for the given function is 6.

If x2 = 60, what is the value of x?
MArishka [77]

Answer:

x = ±2sqrt(15)

Step-by-step explanation:

x^2 = 60

Take the square root of each side

sqrt(x^2) = ±sqrt(60)

x = ±sqrt(60)

x = ±sqrt(4 *15)

x = ±2sqrt(15)

How long can the run be made?
defon

Answer:

L=15\ m

Step-by-step explanation:

we know that

The perimeter of rectangle is equal to

P=2L+2W

In this problem we have

P=42\ m

W=6\ m

substitute in the formula and solve for L

42=2L+2(6)

simplify

21=L+(6)

L=21-6=15\ m
