Answer:
<h2><u><em>
5</em></u></h2>
Step-by-step explanation:
X * 3^2 +2 = 47
X * 9 + 2 = 47
9X = 47 - 2
9x = 45
x = 45 : 9
X = 5
It rounds to zero! lmk if you need anything else
A = P(1+i/n)^nt
A = Total amount paid
P = Principal amount
i = Annual interest
n = number of payments per year
t = time in years
Substituting the values given,
A = 1800(1+0.032/52)^52*10 = $2,478.59
Interest paid = A - P = 2478.59-1800 = $678.59
Second answer is correct.
Answer: C) -7r^2 + 12r - 8
Step-by-step explanation: Simplify the expression.
Hope this helps you out! ☺
I assume that you know Pythagorean theorem, a squared plus b squared equals c squared. There is another part to this where if a squared plus b squared equals c squared exactly then the triangle is right. If a squared plus b squared is greater than c squared than the triangle would be acute. And the opposite for obtuse, I hope this helps!
