A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rat

Yuki888 [10]

A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rate.

from the given table

when x=0 , y=20

when x= 1 , y = 30

We use this information to find exponential growth equation

General form of exponential growth is

$y=a(b)^x$

WE plug in the given values and find out value of a and b

when x=0 , y=20

$20=a(b)^0$

20 = a

Now we find out b

when x= 1 , y = 30

$30=20(b)^1$

divide both sides by 20

$\frac{3}{2} = b$

So exponential function becomes

$y=20(\frac{3}{2})^x$

Now we find the insect population at the end of week 11

We plug in 11 for x

$y=20(\frac{3}{2})^x$

$y=20(\frac{3}{2})^11= 1729.951171875$

Round the answer to nearest whole number

1730 is the insect population at the end of week 11

You begin with $90 in your savings account and your friend begins

Colt1911 [192]

Answer:

F(f) = 15t + 35 represents the total amount of savings your friend would make in t weeks.

F(d) = 10t + 90 represents the total amount of saving you, darian, would make in t weeks.

When you graph the equations, plugging in different values for t, you can see that the graphs intersect at (11,200). This means that at 11 weeks, both you and your friend have the same amount of money saved up, $200. They will not have the same amount of money in 10 weeks.
