Step-by-step explanation:
Only three terms luckily:
8*(1/4)^0 + 8*(1/4)^1 + 8*(1/4)^2 =
8*(1 + 1/4 + 1/16) = 21/2, answer D.
Answer:
5m-50
Step-by-step explanation:
Let Diego current age be x,
Given that Diego’s current age is five times Martina’s age ten years ago
Martina current age = m years
10 years ago Martina's age = m-10
Hence we have
x = 5(m-10) = 5m-50
So we find that Diego's current age can be expressed in terms of m as
Deigo's current age= 5m-50
Verify:
Deigo current age = 5m-50
Hence Martina age 10 years ago = 5m-50 divided by 5 = m-10
Martina current age = m-10+10 = m
Verified.
Answer:
t = [0.493,4.2]
Step-by-step explanation:
The height of the rocket straight up into the air is given by :
We need to find the interval the rocket be at least 43 feet above the ground.
So, the required interval during which the rocket is at least 43 feet above the ground is [0.493,4.2].
