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

A person walks 1/3 mile in 1/9 hour. At what speed is the person walking in miles per hour?
ki77a [65]
Speed (v) could be determined using this following formula
v = distance ÷ time

plug in the numbers
v = \frac{1}{3} : \frac{1}{9}
v = \frac{1}{3} \times \frac{9}{1}
v = 9/3
v = 3

The speed is 3 miles per hour

oee [108]

Answer:

245

Step-by-step explanation:

$49.00 times 5 is 245. The 5 came from the question because it says a normal work week has 5 days so you would multiply $49.00 by 5

Write a paragraph proof.
worty [1.4K]
It is given that line segment BC is congruent to line segment EC and that line segment AC is congruent to DC. Because of the vertical angles theorem, angle BCA is equal to angle DCE. Therefore, triangles CBA AND DEC are congruent by SAS. Using CPCTC, BA is equal to ED.
