Martha has $10,000 saved and wants to attend a college with a current tuition of $10,000 a year. She will graduate from high school in five years. Roughly how much more will Martha need to save for one-year’s tuition to account for an annual rate of inflation of 3%? A. $1,590.00

B. $1,255.00

C. $300.00

D. $3,000.00

A: 1,590.00

Step-by-step explanation:

We can use the simple interest rate equation for this problem: p(1 + r)^t

Step 1: Replace the variables with the amounts given

10000(1 + 0.03)^5

Step 2: Solve/Plug in calc

You will get 1590.00

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
