in 1-3 sentences, explain how we know that the the volume of a pyramid is V=1/3Bh

Answers

Answer:

The formula for finding the volume of a pyramid is V= lwh/3. Taking this into consideration, the length times the width times the height must be one, so we put that over three.

Step-by-step explanation:

The formula for the volume of a pyramid V=1/3Bh can be derived by dividing the pyramid into three identical triangular prisms, each with height h and base area B, and then calculating the total volume of the three prisms.

What is volume?

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
The volume of a pyramid can be derived by considering that a pyramid is made up of a series of triangular cross-sections stacked on top of each other. The area of each triangular cross-section (the base) is given by the formula B = 1/2bh, where b is the base length and h is the height of the triangle. By multiplying the base area B by the height h of the pyramid and then dividing by 3 (to account for the triangular shape), we get the formula V = 1/3Bh for the volume of a pyramid.

Write each Quadratic function in standard form. The 2 picture is my notes to help with the answer.

Answers

Answer:

33) 4x² + 8x + 1

35) -2x² + 36x - 147

         

Step-by-step explanation:

#33: f(x) = 4(x+1) ² - 3

f(x) = 4(x+1) ² - 3

First Step: Multiply (x+1) (x+1)

(x + 1)² or (x+1)(x+1) is a one real double.

A one real double means that there is only one real solution

(x + 1) (x + 1) = x² + 2x + 1

Second Step: Multiply x² + 2x by 4

4(x² + 2x + 1) = 4x² + 8x + 4

Final Step: Put -3 in the Quadratic Function and do -3 + 4 to get your constant

4x² + 8x - 3 + 4

= 4x² + 8x + 1

#35: f(x) = -2(x - 9) ² + 15

First Step: Multiply (x - 9) (x - 9)

Remember, (x - 9) ² or (x - 9) · (x - 9) is a one real double, meaning that there is only one real solution.

(x - 9) (x - 9) = x² - 18x + 81

Second Step: Multiply by -2

-2 (x² - 18x + 81) = -2x² + 36x - 162

Final Step: Add the constant by 15 in the equation. (Hint: the constant is -162)

-2x² + 36x - 162 + 15

= -2x² + 36x - 147

This is how you convert the function into standard form. Hope this helps.
