pentagon [3]3 years ago
5 0

Answer:

D

Step-by-step explanation:

Triangle BDC is a right triangle (If you dont understand I can explain in depth).  Since it's a right triangle, we can use the pythagorean theorem to find the length of BD.  The pythagorean theorem states that the length of the smaller legs squared = the longest side squared.  So we can set up the equation 9^{2}+x^{2}=15^{2} where x is the length of the missing side (BD).  If we were to solve for x, (I think you should know how to do this but if not I can explain), you get 12

Lesechka [4]

Solution

- The number of possible outcomes in the sample space is simply gotten by multiplying out all the events together.

- There are 3 possible days: Tuesday, Wednesday, or Thursday. Thus, there are 3 possible outcomes.

- There are 3 possible times: 3PM, 4PM, or 5PM. Thus, there are 3 possible outcomes again.

- There are also 9 possible classrooms available meaning another 9 possible outcomes.

- Thus, the total possible outcomes in the sample space is

3\times3\times9=81\text{ possible outcomes}

An investment of $7,650 at the rate of 5% and is compounded quarterly. What is the investment at the end of 9 years?
ankoles [38]

Answer:

FV = P(1 + r/t)^nt; where P is the initial investment, r is the rate, t is the number of accumulation in a year, n is the number of years.

FV = 7650(1 + 0.05/4)^(9 x 4) = 7650(1 + 0.0125)^36 = 7650(1.0125)^36 = 7650(1.564) = $11,964.17
