Mrs. Stevens wants to have $18,000 in the bank in 3 years. If she deposits $9500 today at 4% compounded quarterly for 3 years, how much additional money will she need to add after three years to her investment to make her balance $18000? a. $8356.79 c. $7295.16 b. $0 d. $10,704.84

7,295.16

Step-by-step explanation:

A=p(1+i/m)^mn

A=9,500×(1+0.04÷4)^(4×3)

A=10,704.84

The balance she needs

18,000−10,704.84

=7,295.16

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
