Have a look at the image attachment. I've added the points A, B, C, D such that
A = base of the diving board pole, or location of the pool deck
B = the location 1.6 meters directly above point A
C = location of the person's eyes
D = diving board location
The goal is to find the length of segment AD
We are given
AB = 1.6
BC = 3.67
what we want to find is
BD = x
Due to the fact we have similar right triangles ABC and CBD, we can form the proportion below and solve for x
AB/BC = BC/BD
1.6/3.67 = 3.67/x
1.6*x = 3.67*3.67
1.6*x = 13.4689
1.6*x/1.6 = 13.4689/1.6
x = 8.4180625
So BD is 8.4180625 meters
Use this to find the length of AD
AD = AB + BD
AD = 1.6 + 8.4180625
AD = 10.0180625
which rounds to
10.0 meters when rounding to the nearest tenth (one decimal place)

Answer: choice D) 10.0 m
Expanding ln(3x) is simple using the rules for logarithms. Because you can seperate ln(3x) as ln(3*x), that means that you can further expand it to ln(3)+ln(x). Review these logarithm rules to help you expand more logarithms!
6 cups can be served.
REASONING:
You would add 12 and 36 to get 48. In one cup, there are 8 ounces. Divide 48 by 8 to get 6 cups.
Hope this helps!
