Cos(arcsin(u)) = √(1 - u²)
_____
You want cos(α) where sin(α) = u.
You know that
cos(α)² + sin(α)² = 1
cos(α)² = 1 - sin(α)² = 1 - u²
cos(α) = √(1 - u²)

Answer:
28 baskets
Step-by-step explanation:
Total Shots = 100
Backboard and miss = 2/5 of total
That is:

Rim and miss = 32% of total
That is:
32% = 32/100 = 0.32
0.32 * 100 = 32 shots
So, miss = 40 + 32 = 72
The rest, she makes, so left:
100 - 72 = 28 shots
Alicia makes 28 baskets (from 100)
Answer:
Step-by-step explanation:
0.25 = 25/100=1/4
1 mile is equal to 5280 feet
Add 900 to it:
5280 + 900 = 6180
6180 is less than 6200, so 1 mile and 900 feet is less than 6200 feet.
