Answer:

The equation is y=-3x-2

Step-by-step explanation:

The first we need to know is the equation of a line, and it is y=mx+b

where the m is the slope and b is the interception to the y axis

With the information in the question the slope is -3 and the equation thats equal to m. and the y intercept of -2 thats equal to the b value

then y=-3x-2

Samuel plans to install a fence around the perimeter of his yard. His yard is shaped like a square and has an area of 40,000 squ
NISA [10]

Answer:

$450

Step-by-step explanation:

The area of the square is 40,000 square feet so the square's side length is 20 (√40,000).

The company charges $2.50 per foot, and the perimeter is 80 (20*4), so the  cost is $400 ($2.50 * 8).

Add on the $50 installation fee and the total cost is $450 ($400 + $50).

Find side x , give your answer 1 decimal place <br>​
Vladimir [108]

<u>Given</u>:

Let A denote the angle of the given triangle which measures ∠A = 81°

Let B denote the angle which measures ∠B = 40°

The length of the side a = x.

The length of the side b = 7 cm.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the law of sine formula.

Applying the law of sine, we have;

\frac{sin \ A}{a}=\frac{sin \ B}{b}

Substituting the values, we have;

\frac{sin \ 81^{\circ}}{x}=\frac{sin \ 40^{\circ}}{7}

Simplifying, we get;

\frac{0.988}{x}=\frac{0.643}{7}

Cross multiplying, we have;

0.988 \times 7=0.643 x

     6.916=0.643x

       10.8=x

Thus, the length of the side x is 10.8 cm.
