The given function is
<span>f(x) = (x)(2x + 5)
and this should describe a situation with an output of area in square feet.
A rectangular plot with the length 5 feet longer than twice the width has an area that is equal to
</span>f(x) = (x)(2x + 5)
Answer:
x = 21
Step-by-step explanation:
3x = 16 * 4 = 64
x = 64/3
x = 21
The given question is on trigonometry which requires the application of required <em>function</em> so as to determine the <em>value known</em>. So that the <u>length</u> of the guy wire is 67.0 feet.
<em>Trigonometry </em>is an aspect of mathematics that requires the application of some <u>functions</u> to determine the <em>value</em> of an unknown quantity.
Let the <u>length</u> of the guy wire be represented by l, and the angle that the guy wire makes with the <u>stake</u> be θ. So that applying the appropriate trigonometric function to determine the <em>value</em> of θ, we have:
Tan θ = 
= 
Tan θ = 2.75
θ =
2.75
= 70.0169
θ = 
Considering triangle formed by the <u>tower</u> and the <u>stake</u> to determine the value of l, we have;
Cos θ = 
Cos
= 
l = 
= 
l = 67.2515
l = 67 feet
The <u>length</u> of the guy wire is 67 feet.
