59.99 - 59.99 x saving rate = 42.89
with saving rate = r%
59.99 - 59.99 x r% = 42.89
so 59,99 ( 1 - r%) = 42.89
1 - r% = 42.89 : 59.99
1 - r% = 0,7150
r% = 1 - 0,7150
r = 28,5%
Answer:
Step-by-step explanation:
Given
The above triangle
First, we calculate the length LM using Pythagoras theorem.
Collect like terms
Take positive square root
Solving (a): Sin L
Simplify
Solving (b): tan N
Simplify
Solving (c): cos L
This calculated as:
Simplify
Solving (d): sin N
This is calculated using:
If
Then:
So:
Since V = (4/3) * pi * R^3
If R is halved, V' will reduce by a ratio of (1/2)^3 = 1/8
So V' = (1/8)V
