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

Add the mixed number
Tanzania [10]

Answer: 3 <em>7</em>/14 + 2 <em>12</em>/14 = 5 <em>19</em>/14

Step-by-step explanation:

Find the LCM of the denominator.

2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

7 = 7, 14, 21, 28, 35

3 1/2 = 3 7/14

2 6/7 = 2 12/14

<em>3 7/14 + 2 12/14 = 5 19/14</em>

<em></em>
