13. The table represents some points of a linear function.
RUDIKE [14]

Answer:

y=-4x-18

Step-by-step explanation:

To find the slope of the function, you need two points in order, the first point having its x and y coordinates labeled as x1 and y1, and the second point having its coordinates labeled as x2 and y2. then, use the equation for slope, which is m=(y2-y1)/(x2-x1), and plug in the numbers. You should get m=(-10+2)/(-2+4)= -8/2= -4.

Then, use the slope and a point on the graph, and plug it into point slope form, which is y-y1=m(x-x1). No matter what point you use, you should get the same thing. I used the point (-2, -4). Using this point, the steps to arrange the equation in slope intercept form is: y+2=-4(x+4)=> y+2=-4x-16 => y=-4x-18.

A diagonal of a square is 36 feet long. What is the area of the square?
Rzqust [24]
So you can you the Pythagorean theorem to solve this problem.

if each side of the square is a certain length x, then the square is made up of two right triangles.

the sides adjacent to the right angle are length x while the hypoteneus is the diagonal whcih measures 36 feet.

a^2 + b^2 = c^2

x^2 + x^2 = 36^2

2x^2 = 1296

x^2 = 648

x = 25.456

area of a square = x^2 = 648 ft^2

HELP ASAP 20 points Question 12 Multiple Choice Worth 1 points)
ryzh [129]

Answer:

<h2>x = 61.6°</h2>

Step-by-step explanation:

To find the angle of depression we use cosine

cos∅ = adjacent / hypotenuse

37.4 is the hypotenuse

17.8 is the adjacent

\cos(x)  =  \frac{17.8}{37.4}  \\  \\ x =   { \cos( }^{ - 1}  \frac{17.8}{37.4} ) \\  \\ x = 61.6

Hope this helps you
