Answer:
R = 5% per year
Step-by-step explanation:
Solving for rate r as a decimal
r = n[(A/P)^1/nt - 1]
r = 4 × [(4,835.71/3,092.00)^1/(4)(9) - 1]
r = 0.05
Then convert r to R as a percentage
R = r * 100
R = 0.05 * 100
R = 5%/year
Summary:
The interest rate required to get a total amount of $4,835.71 from compound interest on a principal of $3,092.00 compounded 4 times per year over 9 years is 5% per year.
Answer:
Its A
Step-by-step explanation:
Because it is. i took the test :)
1 g/mL ---------- 8.3454 lbs
1.09 g/mL ------ lbs
Ibs = 1.09 x 8.3454 / 1
Ibs = 9.09 / 1
= 9.09 Ibs
hope this heps!
There are three things you have to know:
- A function is convex when its second derivative

- A function is concave when it second derivative

- The derivative of a power,
, is 
So, the first derivative is

and the second derivative is

This implies that the second derivative of a parabola is constant, and of course that 2 doesn't change the sign of
.
This took me a while but I'm pretty sure the answer is

I had to review perpendicular bisectors but yeah it has to do with the midpoint and point slope formula
