Is the volume of a triangular prism one-third the volume of a rectangular prism with the same base area and height? ASAP!!!!!!!
alexira [117]
Yes because a triangles are is 1/3 b x h and a rectangles area is just b x h. The triangle would get smaller because it doesn’t have one corner, and the rectangle would keep a constant size.

Which represents the inverse of the function f(x) = 4x?
zhenek [66]

Answer:

h(x) = 1/4x

Step-by-step explanation:

To find the inverse, first we rewrite the function using y instead of f(x):

y = 4x

Next we switch x and y:

x = 4y

Solve for y by dividing both sides by 4:

x/4 = 4y/4

x/4 = y

1/4x = y

The area of a rectangle is expressed as x4 - 9y2. What are the possible dimensions of the rectangle?
AnnyKZ [126]

This is a stupid question.  The teacher who asked this needs to go back to school.

A = x⁴ - 9y²

That's going to be a number.  As long as it's positive we can choose any length for our rectangle L and we can compute the width by W=A/L.   So the correct answer is the dimensions are L by  (x⁴ - 9y²)/L.

They don't want the correct answer.  They want you to factor this expression.  We'll do it, but don't believe for a second this factoring somehow constrains the possible dimensions of some rectangle.

We use the difference of two squares, a²-b² = (a+b)(a-b)

A = x⁴ - 9y² = (x²)² - (3y)² = (x²+3y)(x²-3y)

Answer: x²+3y  by  x²-3y

Explain how you can use a straightedge and a compass to construct and angle that is both congruent and adjacent to a given angle
lisov135 [29]
Explain how you can use a straightedge and a compass to construct and angle that is both congruent and adjacent to a given angle?

Answer: for this you will simply have to use the straightedge to draw two parallel lines and then you draw a line that goes through them that is perpendicular. You then use the compass to measure the angles, they should be congruent and adjacent.

I hope it helps, Regards.
