Efficiency = (output)/(input).
This could also be written as
efficiency= output/(output+losses)
or
eff=(input-losses)/input

The answer is B.

For an expression to be a polynomial term, any variables in the expression must have whole number powers.

-3/x isn’t a polynomial term because the variable is in the denominator.

Looking at the data it looks like a line. So the answer will be in y+mx+b format.

Knowing it is a line eliminates answers b and c.
looking at options a is says it starts at about .1 when x is zero. We can see this looks pretty close as the left-most dot is below 1 already.

The slope on a is 1/2--> increasing 1 vertically for every 2 horizontally. The pattern mostly follows that rule.

Therefore a (y=1/2x+.1) would be the correct answer

A^2 + B^2 = C^2
7^2 + B^2 = 25^2
49 + B^2 = 625
-49 -49
B^2 = 576
Square root both sides
B = 24
