Answer:
A
Step-by-step explanation:
1. Get 15% of 870:
First, get 10 percent of 870, which is 87, then half that, which is 43.5
Get the 87 and add the 43.5 on it, to get the full 15%, you end up with $130.5, which is the monthly payment.
(Only problem is that im pretty sure you put an extra 0, because if you just wrote 87 dollar's then you would've got 13.05, the actual answer, but if you add an extra 0 then you end up with 130$, just to let you know.)
F(x) = 9x²<span> - 5x + 2
</span>f(-2) = 9(-2)² - 5(-2) + 2
<span>f(-2) = 36 + 10 + 2
</span><span>f(-2) = 48</span>
The slope of the line is 7/4
Previous crime rate = c incidents per 1,000 people
Reduction in crime rate after batman brought the joker to justice = 12%
Hence, new crime rate (per 1,000 people) would be = c - 12%×c
⇒ New crime rate (per 1,000 people) would be = c - 0.12×c
⇒ New crime rate (per 1,000 people) would be = 0.88×c
Hence, now the crime rate is 0.88×c per 1,000 people.
The answer Is 3.482 × 10^9
