Joanna bought a car and after 5 years of payments, she paid $6,250. The initial loan for the car was $5,000. What was the interest rate on Joanna's loan for the 5 years? HELP ME PLS

5%

Step-by-step explanation:

6,250-5000

1,250

divide that by 5

you get 250

250/5000= 0.05

multiply that by 100 to get the percentage (interest rate)

so the answer is a 5% interest rate

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
