Answer:
Step-by-step explanation:
<u>Simplify, rationalize the denominator</u>
- √2/(3 + √5) =
- √2(3 - √5)/(3 + √5) (3 - √5) =
- (3√2 - √10)/(3² - 5) =
- (3√2 - √10)/4
Answer:
Step-by-step explanation:
A. "a pair of pants originally priced at &40$ and a shirt originally priced at $45. He pays $55"—correct

D. "a pair of pants for sale price of $40.60. The pair of pants was originally priced at $58."—correct
(1-0.30)$58 = $40.60
Answer:
w(0) = 1
Step-by-step explanation:
If w(0) is true, replace all x in the equation with 0 and then solve
w(0) = 5^2(0) + 1
w(0) = 25(0) + 1
w(0) = 0+1
w(0) = 1
Answer:
The balance after the payment is $1263.84.
Step-by-step explanation:
The formula for amount after compound interest is

Where, P is principal, r is rate of interest, n is number of time interest compounded in a period, number of periods.
According to the given information,
P=1455.69
r=0.128
n=365
t=45
Put these values in the above formula,


The amount after compound interest is $1478.84. Add late fee chages $35 in this amount and subtract the payment of $250. So, the balance amount after payment is

Therefore the balance after the payment is $1263.84.
