Answer:
what is the question
Step-by-step explanation:
Wow - that is an unusual calculation. You'll need a formula for the monthly payment of a monthly annuity, and it is located here:
http://www.1728.org/annuity3.htm (see formula 2)
You'll find THAT page and THIS page very helpful:
http://www.1728.org/annuitym.htm
rate = rate / 1,200
rate =
<span>
<span>
<span>
0.005166666667
</span>
</span>
</span>
n= number of months = 5 * 12 = 60
monthly amount = [Total] / ([(1 + rate)^(n+1) -1] / [rate]) -1
monthly amount =
55,000 / [[( 1<span>.005166666667)^</span>(61)-1] / 1<span>.005166666667] -1
</span>
monthly amount = 55,000 / [[<span><span>1.3693761617</span> -1</span>] / .005166666667]-1
monthly amount = 55,000 / [[.3693761617] / .005166666667]-1
monthly amount = 55,000 /
((<span>

</span></span></span>monthly amount = 55,000 / (<span>

<span><span><span>monthly amount = 780.2286062293

OR 780.23 (rounded)
Yes, it's just that "simple". LOL
It’s answer D.
A trinomial is a polynomial with 3 term, and D is the only one with 3 terms :)
Answer:
The first derivative of 
is 
.
Step-by-step explanation:
We proceed to find the first derivative of by explicit differentiation and rule of chain:
The first derivative of is .
She drove 2 hours at 35 miles per hour for a total of 35 * 2 = 70 miles.
She drove 3 hours at 48 miles per hour for a total of 48 * 3 = 144 miles.
Her total miles were: 70 + 144 = 214.
Her total driving time was 3 + 2 = 5 hours.
Divide her total miles by total time for her average speed:
214 / 5 = 42.8 miles per hour average speed.
Not sure if you need to round the answer or not.
