Answer : $757
explanation: 57.75 + 9.50 = 67.25
67.25/757
Answer:
.
Step-by-step explanation:
Given:

We need to find 
Solution:
First we will find the value of
.
Now taking
on both side we get;

Now we will find the
.
= 
Now we will find
we get;

Hence
.
13)
there are 2π radians in 1 revolution, and there are 60 seconds in 1 minute, so keeping that in mind, then,

14)


15)
what is the radians per seconds "w" in revolutions per minute? just another conversion like in 13)
cos(6x) = 0
cos⁻¹[cos(6x)] = cos⁻¹(0)
6x = 90
6 6
x = 15°
x = ¹/₁₂π radians
cos(6x) = 0
<span>cos⁻¹[cos(6x)] = cos⁻¹(0)
</span> 6x = 270
6 6
x = 45
x = ¹/₄π radians
cos(6x) = 0
<span>cos⁻¹[cos(6x)] = cos⁻¹(0)
</span> 6x = 450
6 6
x = 75
x = ⁵/₁₂π radians
