Sally deposits 4000 in a certificate of deposit that pays 6.94% simple interest. what is her balance after one year?

4277.6

Step-by-step explanation:

Hello, I can help you with this

Step one

find the profit using a simple rule of three

if

4000 ⇔ 100%

then, how much(x) is 6.94?

x        ⇔ 6.94%

the relation is

the profit is 277.6

hence, her balance after one year is the initial amount plus interest earned

balance= 4000+277.6

balance= 4277.6

I hope it helps, Have a great day

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

the answer is 375 miles
