URGENT The life expectancies (in years) for men and women in the U. S. can be given by the following models:

Women: L=0.13t+77.7L=0.13t+77.7

Men: L=0.24t+69.6L=0.24t+69.6

where tt is the number of years since 1980.

A.) How many years after 1980 do these models predict that the life expectancies of men and women will be the same?


years after 1980 (Round to the nearest tenth of a year.)

B.) Use your rounded answer in part (A) to find the age at which the life expectancies will be the same.


years old. (Round to the nearest tenth.)

the exponential expression to find the value of the cd, in dollars, after t years will be:  

step-by-step explanation:

formula of compound interest:   , where final value after years,   initial value, rate of interest in decimal and number of compounding in a year.

oliver plans to purchase a $1,500 certificate of deposit (cd) at his bank. that means,  

the cd will earn 2.3% interest, compounded semi-annually.

so,   and  

now, plugging these values into the above formula, we will

(rounded to the nearest ten-thousandth)

so, the exponential expression to find the value of the cd, in dollars, after t years will be:
