Ten deer were introduced into a protected preserve. Their expected population doubles each year. Which function represents the s
Shalnov [3]

Answer:

y(t)= 10 (2)^t

Step-by-step explanation:

If t is the number of years given then the expected number can be found by

y(t)= 10 (2)^t

where t takes the value 0,1,2,3, and so on.

Putting t= 0

y(t)= 10 (2)^t

y(0)= 10 (2)^0

y(0)= 10   For the start the number of deer are 10.

Putting t= 1

y(t)= 10 (2)^t

y(1)= 10 (2)^1

y(1)= 20    After 1 year it has doubled to 20

Putting t= 2

y(t)= 10 (2)^t

y(2)= 10 (2)^2

y(2)= 40      After 2 years it has again doubled to 40

Putting t= 3

y(t)= 10 (2)^t

y(3)= 10 (2)^3

y(3)= 80   After 3 years it has again doubled to 80

Andy carried 1/2 gallon of water on a hike. He drank 2/3 of the water. How much water did he drink?
Contact [7]
So,

All we have to do is multiply the amount of water Andy carried by the fractional amount he drank.

1/2 * 2/3

This is pretty simple.  To halve TWO-thirds, just halve the numerator, since it's such a nice number.

Presto.  Half of two is one.

Therefore, 
1/2 * 2/3 = 1/3

Andy drank 1/3 gallons of water on his hike.  That's 5 1/3 cups of water.  I would estimate his hike to be about 3 miles.  Easy peasy.
