D'(p) = -8p + 160
<span>-8p + 160 = 0 </span>
<span>-8p = -160 </span>
<span>p = 20 </span>
<span>~~~ </span>
<span>B) Number of drills sold when p = 20 is </span>
<span>D(20) = [ -4(20)^2 + 160(20) - 270 ] = 1,130 drills </span>
I think this is right, i tried.
Answer:
(m-5) (n-4)
Step-by-step explanation:
mn - 4m - 5n + 20
We will factor by grouping
mn -5n -4m +20
Factor an n out of the first 2 terms and a -4 out of the last 2 terms
n (m-5) -4(m-5)
Now factor out a m-5
(m-5) (n-4)
The answer is c. 16.70% This is based on the posts I've read online regarding this problem. No solution was given.
These are the amounts you have to consider:
List price of new car - 21,450
Sales tax rate: 6.88% - 21,450 x 6.88% = 1,475.76
vehicle registration fee - 1,089
documentation fee - 124
loan term - 3 years, paid monthly. so, 36 months
interest rate - 12.28% compounded monthly.
2004 Dodge Neon value - 6,591
trade in value - 6,591 x 80% = 5,272.80
No mention of down payment so the possible amount to be financed is: 24,138.76
The value of the traded car is only considered after the financing has been paid off.
Answer:
2.6
Step-by-step explanation:
Make this an equation. 5x-4=9. Add 4 to both sides. 5x=13. Divide both sides by 5. x=2.6. So the number is 2.6.
-2/11x=4
11(-2/11x) =4*11
-2x=44
-2x/-2=44/-2
X=-22
