For the billing period from 4/5 to 5/4, Mary's credit card carried the following balances Dates Balance
4/5-4/10 $300.00
4/11-4/19 $420.00
4/20-5/4 $600.00
*What is the average daily balance for the billing period?
*Assume the credit car has an APR of 21.90%. How much is the finance charge for the billing period? Round answer to two digits after the decimal point.
*What will be the new balance on 5/5?

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

answer:   2 multiplied by x =24

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
