Step-by-step explanation:
Answer:
C. You have to multiply both powers to simplify.
The rate of change is x2. So, since it's forty, it became 80 because 40x2=80!
Good luck for a good grade!
Answer:
23.5
Step-by-step explanation:
First the shaded area is 28 but there is a triangle so we have to solve the area of the triangle. (formula for triangle: B x H x 1/2) 3 times 3=9 divided by 2=4.5
28-4.5=23.5
Answer:
1792
Step-by-step explanation:
given,
f (n) = 4 f (n - 1)
here,
f(2) = 4 f ( 2-1)
= 4 f ( 1 )
= 4. 7
= 28
then,
f(3) = 4 f ( 3-1)
= 4 f ( 2)
= 4. 28
= 112
again,
f (4) = 4 f ( 4-1)
= 4 f ( 3)
= 4.112
=448
at last,
f ( 5) = 4 f ( 5-1)
= 4 f ( 4)
= 4. 448
= 1792
