Answer:
3875 feet above sea level
Step-by-step explanation: First, you would subtract 4,500 from 7,000 because you're going down. Then, since you're going up, you would add 1,375.
7,000- 4,500 = 2,500
2,500+ 1,375 = 3875
a) 1.3652
b) 1.3906
Step-by-step explanation:
a) log5 9 = log5 3² = 2log5 3 = 2(0.6826) = 1.3652
b) log5 75/8 = log5 75 - log5 8 = log5 3×25 - log5 8=
log5 3 + log5 5² - log5 8 = 0.6826 + 2 - 1.2920 = 0.6826 + 0.708 = 1.3906
