Answer:
APY = (1 +r/n)^n -1
Step-by-step explanation:
Each period the principal is multiplied by 1 plus the periodic rate: 1 + r/n. For n periods in a year, the effective multiplier is (1 +r/n)^n. The value after this multiplication includes the principal, so to find the interest, we need to subtract the principal. The effective rate is ...
APY = (1 +r/n)^n -1

You didn't ask, but the effective rates for the accounts shown are given in the attachment. The formula bar shows the formula used, and the highlighted cell shows the highest APY.
(I find a spreadsheet is a simple way to do repetitive calculations with minimal chance of error.)
Answer:
7/8
Step-by-step explanation:
well first when you put them together like 3/8 and 7/9 you have to simplfy first. You have to cross simplify 3 and 3. Since they are the saem both turn into one. Now you mulitpy. 7 times 1 is 7 and 8 times one is 8. 7/8
The answer is 810,000. since 387,789 + 387,789 + 34,000 = 809,578. round that to the nearest 10,000. That gives you 810,000.
Answer:
<h2>D) The graph would shift 5 units up.</h2>
Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x - n) - shift the graph n units to the right
f(x + n) - shift the graph n units to the left
------------------------------------------------------------------
We have f(x) = x² - 8
f(x) = x² - 8 <em>add 5 to both sides</em>
f(x) + 5 = x² - 3
Therefore your answer is D)
Similar figures are two different figures of different sizes, but have the same shape
