C. 10. Petra has $7.75 in quarters and dimes. Which relation models this relation?
a. 15Q+ 25D= 7.75
10Q + 35D= 7.75
b. 28Q+8D = 7.75
d. 25Q+ 15D - 7.75
lotion is nonlinear

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
