average rate of change is just the slope from (0,f(0)) to (2,f(2))
basically, average rate of change=slope=
evalaute each
f(2)=4(2)^2=4(4)=16
f(0)=4(2)^0=4(1)=4
so average rate of change=
average rate of change is 6
It is simplified as much as it can go.
x⁴ - 8x² = 0
x⁴ - 8x² + 16 = 0 + 16
x⁴ - 4x² - 4x² + 16 = 16
x²(x²) - x²(4) - 4(x²) + 4(4) = 16
x²(x² - 4) - 4(x² - 4) = 16
(x² - 4)(x² - 4) = 16
(x² - 4)² = 16
The answer is B.
Answer:
30
Step-by-step explanation:
use Pythagoras theorem
hypothenuse of bottom triangle =√24^2+32^2 = 40
x =√50^2-40^2 = 30
