The function f(x)=125(0.9)x models the population of a species of fly in millions after x years.
deff fn [24]

Answer: (B) 3 times as fast

<u>Step-by-step explanation:</u>

rate of change is the "slope" between the given interval.

f(x) = 125(.9)ˣ

f(1) = 125(.9)¹

    = 112.5

f(5) = 125(.9)⁵

     = 73.8

\dfrac{f(5) - f(1)}{5 - 1} = \dfrac{73.8-112.5}{5-1} = -\dfrac{38.7}{4} = -9.675

********************

f(11) = 125(.9)¹¹

       = 39.2

f(15) = 125(.9)¹⁵

       = 25.7

\dfrac{f(15) - f(11)}{15 - 11} = \dfrac{39.2-25.7}{15-11} = -\dfrac{13.5}{4} = -3.375

********************

The rate of change from years 1 to 5 is approximately 3 times the rate of change from years 11 to 15.

What is the distributive property of 24+40
Scorpion4ik [409]
(20+40)+4

So basically the easiest way to remember is for example:
Normal: 69+45
Distributive property: (60+40)+9+5
———————————————————
So if you have 24 you need to distribute the numbers to make them into tens. That’s how you get 4.
———————————————————
I didn’t explain it very well but hope it helped a little bit.

strojnjashka [21]

Answer:

b = 2x²

Step-by-step explanation:

Let the number of bacteria = x

Every hour, the number of bacteria doubles itself, = x * x = x²

But the bacteria started with 2g,

The number of bacteria present is equal to

2 * x² = 2x².

At every hour, the growth of the bacteria is at 2x²
