If f(x) = 5x + 40, what is f(x) when x= -5

Yuliya22 [10]

All we need to do is substitute and solve:

f(-5) = 5(-5) + 40

f(-5) = -25 + 40

f(-5) = 15

Best of Luck!

Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15

Solution:

The function that models the yield is:

$f(x) = -x^2 + 20x + 75$

The average rate of change of f(x) from x = a to x = b is given by the formula:

$\text{ average rate of change }=\frac{f(b)-f(a)}{b-a}$

Find and interpret the average rate of change from year 5 to year 15

$f(5) = -(5)^2 + 20(5) + 75\\\\f(5) = -25 + 100 + 75\\\\f(5) = 150$

$f(15) = - (15)^2 + 20(15) + 75\\\\f(15) = -225 + 300 + 75\\\\f(15) = 150$

Thus average rate of change:

$\text {average rate of change}=\frac{f(15)-f(5)}{15-5}$

$\text {average rate of change}=\frac{150-150}{10}=0$

Thus Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15.

HELP ME it's almost due find the length of the diagonals of rectangle QRST

Westkost [7]

Answer:

11.since diagonal are equal of rectangle

QS=RT

4x+6=6x-4

6+4=6x-4x

2x=10

x=10/2

x=5

now

diagonal :4x+6=4*5+6=26

12.

again

QS=RT

9x+12=11x-10

12+10=11x-9x

2x=22

x=11

now

diagonal=9*11+12=99+12=111

Answer:

the answer is 40.1 cm

Step-by-step explanation:

$\cos( \alpha ) = adjacent \div hypotenuse$

The adjacent in the triangle is 23cm and the Alpha is 55 degrees, so just insert the formula to find the adjacent which is x .
