Answer:
3.9 or less
Step-by-step explanation:
This is because 4 times 7 is equal to 28, so it has to be less than that!
So at the end of the third year, it would be 800 x^3 + 600x^2? And he doesn't work the third summer? Then 800x^3 + 600x^2 = 1650 x = 1.0657758228... so he needs an interest rate of 6.57758.... % compounded annually.
Distance Keith ran = 26 miles
Time it took
= 3 hours 2 minutes = [(3 * 60) + 2] minutes = (180 + 2) minutes = 182 minutes
Hence,
Speed (Rate) =

miles per minute
Hence,
Time taken to complete 1 mile
=

= 7 minutes
Hence, the answer is B.
sin A=Perpendicular/ Hypotenuse
sin A = 7/15
A= arcsin(7/15)
= 27,82 degree
Answer is option (B)
