Answer:
Complex numbers often use the letter i (that is, they often have imaginary elements) while real numbers don't have any imaginary elements. Below are some examples:
Step-by-step explanation:
1+2i is an example of a complex number.
3a - 4b is an example of a real number.
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:
1.5
Step-by-step explanation:
Find the series of the graph. This is where the graph crosses the x axis. They are x = -5, -2, and 0.
Factored: y = x(x+2)(x+5)
8 minutes has 8*60 or 480 seconds. If we divide 3000 meters by 480 seconds, we get an average speed of 6.25 m/s.
Answer is D.
