Answer:
51 cm
Step-by-step explanation:
perimeter = 2 * length + 2 * width
226 = 2 * 62 + 2 * width
226 = 124 + 2 * width
226 - 124 = 2 * width
102 = 2 * width
102/2 = width
51 = width
The x-intercept is present where y = 0
2x + 5y - 10 = 0
2x - 10 = -5y
2x - 10 = -5(0)
2x = 10
x = 5
The y-intercept is present where x = 0
2x + 5y = 10
2x + 5y - 10 = 0
5y - 10 = -2(0)
5y = 10
y = 2
Answer:
f(-2) = 1/9
Step-by-step explanation:
Plug in -2 to x in the equation:
f(x) = 3^x
f(-2) = 3^(-2)
Solve. Note that if there is a negative in the power, you must flip the "fraction" and set it over 1. The answer itself does not become negative:
f(-2) = 1/(3^2)
f(-2) = 1/(9)
f(-2) = 1/9 is your answer.

The answer is D. You just move 10 units down from point F.
