Naomi's parents want to have $50,000 saved for her college education. if they invest $20,000 today and earn 7% interest compounded annually, about how long will it take them to save the $50,000?

13.543 years ( approx )

Step-by-step explanation:

Here, the principal amount = 20,000

Annual rate of interest = 7 %

Let the amount will be $ 50,000 after t years,

The total compounded amount after t years = $ 50000

By taking log on both sides,

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

17   x 256=4352

sorry if this is wrong, i'm new.
