what is the final amount of 17.50 that is put into a saving account with 4 annual interest rate compounded yearly for 25 years?

1 answer:

6 0

To find the total amount, you will use the formula for finding compounded interest. This means you will be paid interest on top of the interest you have earned each year.

A = P(1 + r)^nt
P stands for the principal.
r is the interest rate when compounded annually
nt is the number of years

A = 17.50(1 + 0.04)^25
A = $46.65

This person would have $46.65 after 25 years.

Initial value problems dy/dx+2y=3. Y(0)=1

Pavel [41]

The initial value equation is $y = \frac 12(3 - e^{-2x})$

<h3>How to solve the initial value?</h3>

The equation is given as:

$\frac{dy}{dx} +2y = 3$

Where

Y(0) = 1

Subtract 2y from both sides in the equation

$\frac{dy}{dx} = -2y + 3$

Rewrite as:

$\frac{dy}{-2y + 3} = dx$

Integrate both sides of the equation

$-\frac 12\ln|-2y + 3| = x + C_o$

Multiply through by -2

$\ln|-2y + 3| = -2x + C_1$

Take the exponent of both sides

$-2y + 3 = Ce^{-2x$

Next, we solve for C under the initial condition Y(0) = 1.

This gives

$-2(1) + 3 = Ce^{-2 * 0$

Evaluate

-2 + 3 = C

Solve for C

C = 1

Substitute C = 1 in $-2y + 3 = Ce^{-2x$

$-2y + 3 = e^{-2x$

Next, we solve for y

$y = \frac 12(3 - e^{-2x})$

Hence, the initial value equation is $y = \frac 12(3 - e^{-2x})$

Answer:

Molly's Z score for LSAT

z-score=-2

Molly's Z score for MCAT

z-score=2

Step-by-step explanation:

z-score for LSAT

Molly's score=120

mean=150

Standard deviation=15

z-score= (Molly LSAT score-mean)/standard deviation

z=120-150/15=-30/15=-2

z-score for MCAT

Molly's score=52

mean=40

Standard deviation=6

z-score= (Molly MCAT score-mean)/standard deviation

z=52-40/6=12/6=2
