Consider the volume of a rectangular pyramid, one whose base is not square. Does changing one of the three variables (length, wi
user100 [1]

Let

L------> the length of the base of the pyramid

W-----> the width of the base of the pyramid

H-----> the height of the pyramid

V------> Volume of a rectangular pyramid


we know that

V=(1/3)*[L*W]*H

so

the three variables are going to have the same influence on the volume


example

case a) let's change the variable L (we reduce the variable by half)

L=(1/2)*L

the new volume is equal to

V new=(1/3)*[(L/2)*W]*H-----> V new=(1/2)*V

the new volume is half the original volume


case b) let's change the variable W (we reduce the variable by half)

W=(1/2)*W

the new volume is equal to

V new=(1/3)*[(W/2)*L]*H-----> V new=(1/2)*V

the new volume is half the original volume


case c) let's change the variable H (we reduce the variable by half)

H=(1/2)*H

the new volume is equal to

V new=(1/3)*[L*W]*H/2-----> V new=(1/2)*V

the new volume is half the original volume


therefore


the answer is

the three variables have the same influence on the volume

How do I find x in this triangle?
Scilla [17]
Since the total degree of a triangle is 180, subtract 44 from 180 = 136. Divide it by two, and you get 68. I believe this is correct but don't take my word for it. Good luck!

I need help To find gradient and y-intercept...
suter [353]

Answer:

a) the gradient of the linear graph is: \mathbf{\frac{-1}{3} }

b) the y-intercept of linear graph is -1

Step-by-step explanation:

a) Find the gradient of the linear graph.

The formula used to find gradient is same as slope

Gradient=\frac{Change \ in \ y \ coordinate}{Change \ in \ x \ coordinate}\\or\\Gradient=\frac{y_2-y_1}{x_2-x_1}

Take any 2 points from the graph.

I will take: (-3,0) and (0,-1)

Putting values in formula and finding gradient

Gradient=\frac{y_2-y_1}{x_2-x_1}  \\Gradient=\frac{-1-0}{0-(-3)} \\Gradient=\frac{-1}{3}

So, the gradient of the linear graph is: \mathbf{\frac{-1}{3} }

b) Find the y-intercept of linear graph

The y-intercept of linear graph is the value of y at the point where the line crosses the y axis.

So, in the given graph, that point is -1

So, the y-intercept of linear graph is -1
