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.

What is 2/5% of 820?<br><br> 1.8<br><br> 2.05<br><br> 2.88<br><br> 3.28
Margarita [4]

Answer:

D) 3.28

Step-by-step explanation:

820/x=100/2.5

(820/x)*x=(100/2.5)*x       - we multiply both sides of the equation by x

820=40*x       - we divide both sides of the equation by (40) to get x

820/40=x

20.5=x

x=20.5

now we have:

2.5% of 820=20.5

last month Dory biked 11 times as many miles as Carly. Together they biked a total of 156 miles.How many miles did Dory bike las
matrenka [14]
Dory = 11 x Carly

Together => d + c = 156

11c + c = 156

12c = 156
C = 156 : 12
C = 13
Carly biked 13 miles

Dory = 11 x c = 11 x 13 = 143 miles

Prove
143 + 13 = 156 miles together
