Step-by-step explanation:
By Law of Indices, (a^m)^n = a^(mn).
Hence (h²)^(-3) = h^(-6) or 1/h⁶.
The general form for a parabolic dish is:
y=x^2/(4f), where f=focus' y coordinate when x=0
So if you are given the equation:
8y=x^2, you need only to rearrange it to the form y=x^2/(4f)
y=x^2/8
Since 8=4f, f=2 inches and the focal point of course (0,2)
500 - 125 = 375
72.50 × 6 = 435
435 - 375 = 60.
Divide the part (60) by the whole (500) then multiply by 100 to get the percent.
60 / 500 = .12
.12 × 100 = 12%
The correct answer is B
Answer:
A
Step-by-step explanation:
An educated guess because I really forgot how to do these
Answer:
yes it would be 1.25 because 1/4 is .25 and 1 is a whole number
