Answer
I'll help with part a.
Convert revolutions per minute to revolutions per second. Next, convert from revolutions per second to radians per second. Finally, plug the numbers into the formula for angular velocity (this involves the diameter/radius value)
Answer:

Answer:
$21
Step-by-step explanation:
multiply 1.75 times 4, which is 7
then multiply 7 times 3, which is 21
Answer:
31.3
Step-by-step explanation:
Reference angle given = 56.1°
Hypotenuse = 56.1
Adjacent side = x = ?
We would apply CAH, which is:
Cos 56.1° = Adj/Hyp
Cos 56.1° = x/56.1
56.1 × Cos 56.1° = x
31.2895006 = x
x = 31.3 (approximated to the nearest tenth)
The mountain climber has travelled 75 feet below sea level while descending down a cliff.
Given:
- A mountain climber at sea level starts descending down a cliff.
- Her location can be represented by -75 ft.
To find:
The distance travelled by a mountain climber.
Solution
- Distance ascending above sea level is taken in a positive direction.
- Distance descending down sea level is taken in a negative direction.
- This negative and positive only represents the direction
The location of mountain climber after descending from cliff = -75 ft
The distance covered by the mountain climber = 75 ft
The mountain climber has travelled 75 feet below sea level while descending down a cliff.
