Answer:
Step-by-step explanation:
Factor constant terms:
Divide both sides by -2:
Expand trigonometric functions using the fact:
So:
Factor sin(x) and constant terms and multiply both sides by -1:
Split into two equations:
For (1)
Add 1 to both sides and divide both sides by 8:
Take the inverse cosine of both sides:
For (2)
Simply take the inverse sine of both sides
Therefore, the solutions are given by:
You just need to find the circumference (the outside of the wheel) and then multiply that by how many times it turned
circumference is d* pi so your diameter 19/2 times pi (22/7) is about 29.86 ft
times that by 133 and you get exactly 3971 feet
Answer:
15 scarves
Step-by-step explanation:
CROSS MULTIPLICATION METHOD
5 YARDS = x
⅓ YARDS = 1 scarves
⅓x = 5
x = 5×3
x = 15
It’s about 13.925. I rounded up
