What is the surface area of the square pyramid represented by the net? 9 m Enter your answer in the box 6 m 9m 6 m 9 m m 9 m​
Darya [45]

Answer:

144

Step-by-step explanation:

On this shape we are going to splt up the 4 triangles for the square to make it simple.

So, firstly, plug is the h an w of one of the triangles into the formula for the area of a triangle which is hxw/2

H=9

W=6

9x6/2=27

Then multiply the area of the triangle, 27, to get the total area of all 4 triangles (since they all have the same measurements)

27x4=108

108 is the area of all 4 triangles

Next, just put the l and w into the equation for the area of a square which is lxw

L=6

W=6

6x6=36

36 is the area of the square

Lastly, just add the areas of the triangles and the square together

108+36=144

144 is the total area/surface area, of the pyramid

How do I make a formula for a line if they only give me the intercept and the slope
Eddi Din [679]
Well what you want is y = mx + b
m = slope
b = intercept for y
with that just substitute in the slope and the intercept, but leave the x and y as it is. So later on you can put in a x coordinate and get the y coordinate through that, hope this helps!

7. Write the slope-intercept form of the equation of the line graphed below.​
Stels [109]

Answer:

The answer to your question is y = \frac{-1}{2} x - 1

Step-by-step explanation:

Process

1.- Get to points of the line

    A (-2, 0)

    B (0, -1)

2.- Find the slope of the line

Slope = m = \frac{y2 - y1}{x2 - x1}

Substitution

             m = \frac{-1 - 0}{0 + 2} = \frac{-1}{2}

3.- Find the equation of the line

              y - y1 = m(x - x1)

Substitution

              y - 0 = -1/2(x + 2)

Simplification

                   y = -1/2x - 1
