Let f(x)=100/-10+e^-0.1x

what is f(−11)?

For f(-11) replace x with -11 and solve:

f(-11) = 100 / -10 +e^-0.1(-11)

f(-11) = 100 / -10 +e^1.1

f(-11) = -14.3

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
