Use a calculator to help solve the problem.
The life expectancy of white females can be estimated by using the function
= 78.5(1.001)x,
where x is the current age. Find the life expectancy of a white female who is currently 50 years old. Give the answer to the nearest tenth.
L = ______ yr
Replace x with 50 and then multiply 78.5 x 1.001 x 50 to get your answer.
Thank you, big help!
your formula makes no sense at all
according to your formula the life expectancy of this woman would be
78.5(1.001)(50) = 1946 years
was it
L = 78.5(1.001)^x ??
then L = 78.5(1.001)^50 = 82.5
that makes more sense
Reiny is right, this formula can't be right. Raising it to the power of x makes more sense.
To find the life expectancy of a white female who is currently 50 years old using the given function L = 78.5(1.001)^x, where x is the current age:
1. Substitute the current age, 50, into the equation.
L = 78.5(1.001)^50
2. Use a calculator to evaluate the expression.
L ≈ 78.5(1.001)^50 ≈ 78.5(1.05135) ≈ 82.854675
3. Round the answer to the nearest tenth.
L ≈ 82.9 years
Therefore, the life expectancy of a white female who is currently 50 years old is approximately 82.9 years.
