TanA equals opp/hyp so 12/15 or 4/5
Answer:
- payment: $413.93
- total repaid: $74,507.40
- interest: $22,507.40
Step-by-step explanation:
(a) The monthly payment A on principal P at monthly rate r for n months can be computed using ...
A = Pr/(1 -(1+r)^-n)
For P=$52000, r = .051/12 = 0.00425, n = 12*15 = 180, the payment is ...
A = $52000·0.00425/(1 -1.00425^-180) ≈ $413.93
(b) The total of 180 payments is ...
180 · $413.93 = $74,507.40
(c) The difference from the principal is the interest paid:
$74,507.40 -52,000 = $22,507.40
Answer:
( 3 , 25.5 )
Step-by-step explanation:
1. Plug in the equation of y into the first equation
2. Solve for x by merging together like terms from both sides
3. plug in x into the y equation
G(x) is the result of moving f(x) vertically up from -3 to 1
so k = 1 -(-3) = 4
