Answer:
h = 10sin(π15t)+35
Step-by-step explanation:
The height of the blade as a function f time can be written in the following way:
h = Asin(xt) + B, where:
B represets the initial height of the blade above the ground.
A represents the amplitud of length of the blade.
x represents the period.
The initial height is 35 ft, therefore, B = 35ft.
The amplotud of lenth of the blade is 10ft, therefore A = 10.
The period is two rotations every minute, therefore the period should be 60/4 = 15. Then x = 15π
Finally the equation that can be used to model h is:
h = 10sin(π15t)+35
Answer:
D. none of the above.

<h2>
Hello!</h2>
The answer is:
The correct option is
a) 
<h2>
Why?</h2>
Since a right triangle is formed, we can calculate the resultant force using the Pythagorean Theorem which states that:

Where,
c, is the hypothenuse.
a, is one triangle leg.
b, is the other triangle leg.
So, we are given the information:


So, calculating the resultant force (hypothenuse), we have:

Hence, the expression that would find the result velocity is:
a) [tex]Resultant=\sqrt{22^{2} +4^{2} }[/tex]

The length of the ladder nearest hundredth of a foot is 23 feet.
We have given that,
An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 20 feet up.
The ladder makes an angle of
the ground.
<h3>
What is the sin ratio?</h3>

Therefore we get,



Therefore, The length of the ladder nearest hundredth of a foot is 23 feet.
