The population P of a small town, measured in hundreds, is modeled by the inverse of the function P−1(t) = 10ln(50t − 1000), whe

AleksandrR [38]

Using the inverse function, it is found that the equation is:

$P(t) = \frac{e^{0.1t}}{50} + 20$

It's initial value is 20.

---------------------------

We want to find the inverse of:

$y = P^{-1}(t) = 10\ln{50t - 1000}$

To do this, we exchange y and t, and isolate y.

Then:

$10\ln{50y - 1000} = t$

$\ln{50y - 1000} = \frac{t}{10}$

$e^{\ln{50y - 1000}} = e^{0.1t}$

$50y - 1000 = e^{0.1t}$

$50y = e^{0.1t} + 1000$

$y = \frac{e^{0.1t} + 1000}{50}$

$y = \frac{e^{0.1t}}{50} + \frac{1000}{50}$

$P(t) = \frac{e^{0.1t}}{50} + 20$

It's initial value is:

$P(0) = \frac{e^{0.1(0)}}{50} + 20 = 0.02 + 20 = 20.02$

Rounding, 20.

Which equations are true?

Vlad [161]

Answer:

Step-by-step explanation:

1)4.5m+4.7=20m+47

4.5m-20m=47-4.7

-15.5m=42.2

m=-2.72

2)14+21w=7(2+3w)

41+21w=14+21w

21w-21w=14-41

3)49r+35=7(7r+35)

49r+35=49r+245

49r-49r=245-35

4)9(8h-3)=72h-27

72h-27=72h-27

72h-72h=-27+27

5)5.2+5.3t=10+15t

5.3t-15t=10-5.2

-9.7t=4.8

t=4.8/-9.7

t=0.49

6)6f+3.111=18f-33

6f-18f=-33-3.111

-12f=-36.111

f=-36.111/-12

f=3.01

jake is getting a new phone! he buys the service is $50 per month. write the funtion that would represent on how much jake sends

I am Lyosha [343]

Since x=months,

50x=y

Where x is the number of months times the monthly charge. Y is just the output, or end value.

I hope this helps!
