Question: solve for r: 6 ^ (2r) = 800
Answer: 1.87
Step-by-step explanation:
6 ^ (2r) = 800
log(6 ^ (2r)) = log(800)
2r log(6) = log(800)
r = log(800) / (2 log(6))
r = 1.86537641979
round
r = 1.87
log can be any logarithm function.
6^(2×1.86) = 784.734328546
6^(2×1.87) = 813.365367336
Answer:
d = 36 km
Step-by-step explanation:
Speed of Jim, v = 18 km/h
Time, t = 2 hours
We need to find the distance covered. We know that the speed of an object is equal to the distance covered by it divided by total time taken.

So, he will cover 36 km.
Well it would be 4 2/3 or 14/3
