as the product of 90 degrees and 20 degrees
30x60=1800
90x20=1800
Y=mx+b
m=slope
b=yintercept
given
y=-2x+3 and
y=-4x-1
first equation is slope -2 and yintercept 3
second is slope -4 and yintercept -1
3rd option
Step One: Find 25% of 48.
Step Two: Subtract that number from 48.
48 * 0.25 = 12
48 - 12 = 36

Answer:
$32.10
Step-by-step explanation:
The amount to be accumulated in 15 years is the future value of the sinking fund, hence, using the future value formula below, we can determine the required weekly payment as appropriate:
Future value=weekly payment*(1+r)^n-1/r
Future value=$35,000
weekly payment is the unknown
r=weekly interest rate=4.25%/52=0.08173077%
( I use 8 decimal places in order to achieve accuracy)
n=number of weekly payments in 15 years=15*52=780
35000=weekly payment*(1+0.08173077%
)^780-1/0.08173077%
35000=weekly payment*(1.89125311
-1)/0.000817308
35000=weekly payment*0.89125311
/0.000817308
weekly payment=35,000*0.000817308
/0.89125311
weekly payment=$32.10
0.5-0.24.....hmm...1/4 is half of 1/2....so what could you estimate?
