Answer:
C.) Y= 5/8x + 1 1/2
Step-by-step explanation:
To write the equation of a line, calculate the slope between points (4,4) and (-4,-1). After, substitute the slope and a point into the point slope form.
Substitute m = 5/8 and the point (4,4) into the point slope form.
<u>End behavior: </u>
The parent function is: f(x) = x³, which starts (from the left side) at -∞ and ends (on the right side) at +∞.
<u>Zeroes:</u>
f(x) = x³ + 2x² - 8x
0 = x³ + 2x² - 8x
0 = x(x² + 2x - 8)
0 = x(x + 4)(x - 2)
0 = x 0 = x + 4 0 = x - 2
x = 0 x = -4 x = 2
<u>Intervals:</u>
Put the zeroes in order: -4, 0, 2
since f(x) is increasing from the left then the interval from -4 to 0 is positive and the interval from 0 to 2 is negative.

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.
