When peggy joe was born, her father deposited $2000 in a savings account in her name. at that time the bank was paying 6% interest compounded semiannually on saving accounts. after 10 years, the bank changed to an interest rate of 6% compounded quarterly. how much had the $2000 amounted to after 18 years when money was withdrawn for peggy to use to pay her college expenses?

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
