Answer:
see below
Step-by-step explanation:
The radius is 1/2 of the diameter
r = 1/2 d
r = 1/2(4) = 2 inches
The circumference is given by
C = 2 * pi * r
C = 2 * pi * 2
C = 4 pi inches
Using 3.14 as an approximation for pi
C = 12.56 inches
Answer:
see below
Step-by-step explanation:
The coefficients are 19Cr for r from 0 to 19, as shown in the first and last choices. The sum of the powers of the factors is 19, as shown in the first and last choices. The only difference between the first and last choices is the order of terms in the sum. Both have the same total, and both are equivalent expansions of the given expression.
If you prefer the higher powers of m to appear first, then the last choice is appropriate.
The time of takeoff of this hovercraft would be 0 seconds, as if you were starting a timer. So, if you plug in 0 for x (unit for seconds) in your equation, it will look like this:
h(0) = -3(0 - 3)² + 108
Parenthesis first
h(0) = -3(-3)² + 108
Exponents next
h(0) = -3(9) + 108
Multiplication
h(0) = -27 + 108
Combine like terms
h(0) = 81: The height of the hovercraft at the time of takeoff is 81 meters!
Hope this helps :)
