A scientist uses the equation shown below to predict the future population of a species. In the equation, y represents the estimated population and trepresents the number of years.
y=150•4^t

Which number is closest to the value of y when t=3/2

Answer 1

1200 i think

Explanation:

i used a calculator since its hard for me to do mental math

question 2

(sorry i replied late i was doing some of my school work)

so you make A be equal to 5000 since you want to know when his account will be that much money sooo

5000 = 2000(1.07t)

you divide 2000 from both sides

5000/2000 = 1.07t

5/2 = 1.07t

now you have to isolate t to solve for it

soo divide 1.07 to both sides

5/2 / 1.07 = t

t is equal to about 2.34 or 2 years (depends on what it tells you to round to) in the calc t is 2.336448598

so in maybe 2 years he'll have 5000 dollars
