(f-g)(x)=f(x)-g(x)
(f-g)(144)=f(144)-g(144)

f(144)=√144+12=12+12=24
g(144)=2√144=2(12)=24

(f-g)(144)=24-24=0

Lin's sister has a checking account. If the account balance ever falls below zero, the bank charges her a fee of $5.95 per day.

VladimirAG [237]

Answer: No, the bank will not keep charging her the $5.95 after the deposit is made.

Step-by-step explanation:

Today, Lin's sister's balance is -$2.67

She gets charged $5.95 per day.

There are 14 days until she can charge some money in the bank account, so the bank will charge $5.92 14 times

So her balance after 14 days will be:

Balance = -$2.67 - $5.95*14 = -$85.97

When she charges the $430 in the account, her balance will be:

Balance = -$85.97 + $430 = $344.03

So now she has a positive balance, which means that the bank does not charge her anymore.

Answer:

5. tan(25) = 12/x

x · tan(25) = 12

x = 12/tan(25)

= 25.734

≈ 25.73

6. tan(52) = x/3.4

x = 3.4tan(52)

= 4.352

≈ 4.4
