Answer:
$152,419.36
Step-by-step explanation:
The future value of an ordinary annuity is given by the formula ...
FV = P((1 +r/12)^(12t) -1)/(r/12)
where P is the monthly payment, r is the annual interest rate, and t is the number of years.
<h3>Annuity value</h3>For P = 350, r = 0.021, and t = 27 (years to retirement age), the value is ...
FV = 350((1 +0.021/12)^324 -1)/(0.021/12) ≈ $152,419.36
The value of Jolene's retirement account when she turns 60 will be $152,419.36.

Answer:
Step-by-step explanation:
Paraboloid z = 6 + 2x^2 + 2y^2 ----- ( 1 )
plane z = 12
equation 1 becomes
12 = 6 + 2( x^2 + y^2 )
hence : ( x^2 + y^2 ) = 3
This shows that the solid lies under the parabolic and above the disk 0 : x^2 + y^2 ≤ 3
attached below is the remaining part of the solution
We can write this as two equations. Call Mr. Anders' age A and Kate's age K:
Then solve for A in the second equation:
Substitute this into the first equation:
Then solve for A in the second equation:
