Answer:
Step-by-step explanation:
For each right-angled triangle:
Because
we have an equation
multiplying both sides by x, we get
dividing both sides by 0.4 and
using calculator, we divide 12 by 0.4
and finally x=30

Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 1, 4 ] , then
f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36
f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then
average rate of change = =
=
= - 6
