Answer:

128.00

Step-by-step explanation:

4.50 × 13 = 58.50

6.75 × 9 = 60.75

58.50 + 60.75 = 119.25

119.25 ≈ 128.00

A researcher determines that the number of bacteria increase at a rate modeled by =25*2^x. What is the growth rate?
dolphi86 [110]

Answer:

100%

Step-by-step explanation:

An exponential equation with a growth rate can be expressed as: f(x)=A(1+r)^x where r is a positive number, and represents the growth rate.

In this case since the base of the exponent equals 2, that means r=1, since 1+1=2. This means it has a growth rate of 100%, which makes sense, since the base is 2, meaning it doubles or increases by 100% every time x increases by 1.

cestrela7 [59]

Answer:

19600

Step-by-step explanation:

For every year the profit increases by 40% so to figure out the profit from 2017 to 2018 you do 10,000*1.4 to and get 14,000. To get 2019's profit you do the same process, but use 2018's profit of 14,000 instead of 2017's profit to get 19,600.
