Answer:
$315
Step-by-step explanation:
You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.

<em>I = interest amount</em>
<em>P = principal amount</em>
<em>r = interest rate (decimal form)</em>
<em>t = time</em>
<em />
Now we can plug in the values into the equation:


This means that Rachel earned $315 worth of interest in the 15 year period.

Answer:
Hi, so if I remember correctly, you find both parts of the figure using the area formula for each shape and then add them together. Then if you have correct math you should have your answer.
Step-by-step explanation:
1. Take 4 times 11 because you use base times height- that should be 44
2. Then take one half times 14 times 8( one half times the base times the height)
3. Add both of the answers of 1 and 2 and that should be the answer
The product is -12 for this problem
For P(t) = 920*1.06^(2t), the current population is 920, the percentage growth rate is 6% semiannually, and the population in 4 years will be 920*1.06^8 = 1466.
Selection B is appropriate.
_____
The 2 in the exponent means the growth factor 1.06 is applied twice for each increment of t, that is, twice in 1 year (semiannually).
