Answer:

Step-by-step explanation:

According to the problem, the population is expected to grow by 11% yearly. So, the equation that best model this scenario is the last option.

We can get this answer just by observing the coefficient of the variable, it has to indicate more than 1 or 100%, that's why it cannot bet 0.11x, because that shows a decrease.

So, an increase of 11%, would be 100% + 11%, which is 111% or 1.11.

Therefore, the right answer is the last option: y = 13,000(1.11)x

Step-by-step explanation:

Put the given numbers into the given formula and do the arithmetic.

(a) The temperature of sample 1 is ...

y = (100 -24)e^(-0.12·20) + 24 ≈ 30.9

___

(b) The temperature of sample 2 is ...

y = (100 -4)e^(-0.12·10) +4 ≈ 32.9

The function f(x) is a cubic function and the zeros of f(x) are -3, -2, and 1. The y-intercept of f(x) is -24. Write the equatio

Serga [27]

Answer:

f(x) = 4x³+16x²+4x-24

Step-by-step explanation:

Factors are (x+3)(x+2)(x-1)

(x+3)(x²+2x-x-2)

(x+3)(x²+x-2)

x³+x²-2x+3x²+3x-6

x³+4x²+x-6

This could have been the function but the intetcept is 6 here.

So we'll take a miltiple of this one such that the intercept becomes-24

-24/-6 = 4

That multiple is 4

f(x) = 4(x³+4x²+x-6)

f(x) = 4x³+16x²+4x-24
