<h3>Given</h3>

Future value of an investment at 4.75% compounded weekly is $25,000

<h3>Find</h3>

The present value of the investment, to the nearest dollar

<h3>Solution</h3>

The multiplier is (1 + .0475/52)^(52·5) ≈ 1.2679375, so the amount required is found from

... 1.2679375×present value = 25,000

... present value = 25,000/1.2679375 ≈ 19,717

$19,717 needs to be placed in the account now.

_____

When an annual interest rate r is compounded n times per year, the annual multiplier is (1 +r/n)^n. Here, we have n=52 (weeks per year). The multiplier is applied 5 times (raised to the 5th power) to obtain the result of a 5-year investment.

Solve the equation for y. Identify the slope and y- intercept. Then graph the equation. 2y-3x=10
Shkiper50 [21]

Answer:

y=3/2x+5

The slope is 3/2 and the y-intercept is 5

Step-by-step explanation:

Solving for y will give us the slope and y-intercept

Isolate y

2y/2=10+3x/2

y=5+3/2x

The slope is 3/2 and the y-intercept is 5

Graph it by graphing (0,5) and using the slope (up 3 over 2) to put other points

krek1111 [17]

Answer:

x = 3/4 or x = 0.75

Step-by-step explanation:

y=2x²-3x+4

y'=4x-3 = 0

x = 3/4 .... answer

or

x = - b/2a    ...y=ax²+bx+c

x = - (-3)/(2*2) = 3/4
