Question 20 (2 points Karl owes $7,464 on a credit card with a 20.4% interest rate compounded monthly. What is the monthly payment he should make in order to
pay off this debt in 12 months, assuming he does not charge any more purchases with the card? (2 points)

42.4

step-by-step explanation:

convert to decimal

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
