Answer:
A) 5 units
Step-by-step explanation:
ABC is a 30-69-90 degree triangle whose sides, respectively, are in the ratio of 1 : : 2
so if the hypotenuse is 10, the side opposite the 30° angle is half of that, or 5
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.
