Answer:

a = 1

Step-by-step explanation:

First, you subtract 6 from both sides and you end up with a² = 1. Since one cannot be squared or square rooted, a = 1. I hope this helps!

Answer:

x = 8.3

y = 20.3

Step-by-step explanation:

$21-\frac{2}{3} = 20\frac{1}{3}$ or $20.3$

$9-\frac{2}{3} = 8\frac{1}{3}$ or $8.3$

A farmer is constructing a rectangular pen with one additional fence across its width. Find the maximum area that can be enclose

konstantin123 [22]

The maximum area of the pen is the highest area the pen can have

The maximum area is 16200 square yards

Let the dimension be x and y.

So, the perimeter is given as:

$\mathbf{P = 360}$

Because it has one additional fence, the perimeter is calculated as:

$\mathbf{2x + y = 360}$

Make y the subject

$\mathbf{y = 360 - 2x}$

The area is calculated as:

$\mathbf{A = xy}$

Substitute $\mathbf{y = 360 - 2x}$

$\mathbf{A = x(360 -2x)}$

Expand

$\mathbf{A = 360x -2x^2}$

Differentiate

$\mathbf{A' = 360 -4x}$

Set to 0

$\mathbf{360 -4x = 0}$

Rewrite as:

$\mathbf{4x = 360}$

Divide both sides by 4

$\mathbf{x = 90}$

Substitute 90 for x in $\mathbf{A = 360x -2x^2}$

$\mathbf{A = 360 \times 90 - 2 \times 90^2}$

$\mathbf{A = 16200}$

Hence, the maximum area is 16200 square yards

Let(-8,3) be a point on the terminal side of theta . Find the exact values of sin theta ,csc theta , and cot theta sin theta = c

Marizza181 [45]

When we draw the terminal side in a Cartesian plane, this side is located at quadrant 1. We have to solve angle theta in order to obtain the trigonometric functions. First, we solve the angle in the triangle formed of the terminal side.

tan alpha = 3/8
alpha = 20.56°
theta = 180° - 20.56° = 159.44°

<span>sin theta =0.35
csc theta =2.85
<span>cot theta = -8/3</span></span>
