Identify the volume of a regular triangular pyramid with base edge length 14 ft and height 9 ft.

Answers

Answer:

The volume is 588 ft³

Step-by-step explanation:

[tex]v = a {}^{2} \frac{h}{3} = 14 {}^{2} \times \frac{9}{3} = 588[/tex]

Answer:

254.6 ft3 F

Step-by-step explanation:

To find the volume of the pyramid, first calculate the area of the base.

As the pyramid is the regular triangular pyramid, the base is an equilateral triangle.

To find the area of the equilateral triangle, calculate the length of the height.

Since the triangle is equilateral, each angle in the triangle equals 60°.

The height forms a 30°- 60°- 90° triangle. One leg of this triangle is equal to half of the side of the large triangle, or 7 ft. The other leg of the triangle is equal to 73‾√ ft by the 30°- 60°- 90° Triangle Theorem.

Therefore, the length of the height of the triangle is 73‾√ ft.

To find the area of the base of the pyramid, B, use the formula for the area of a triangle, B=12bh.

Substitute 14 for b and 73‾√ for h.

B=12⋅14⋅73‾√

Simplify.

B=493‾√ ft2

To find the volume of the pyramid, use the formula for the volume of a pyramid, V=13Bh.

Substitute 493‾√ for B and 9 for h.

V=13⋅493‾√⋅9

Simplify.

V=1473‾√

Use a calculator to approximate.

V≈254.6 ft3

Therefore, the volume of the regular triangular pyramid is about 254.6 ft3.

The midpoint of a segment is 19,5) and one of the endpoints is (13,81 What are the coordinates of the otherendpoint

Answers

Answer:

[tex](25,-71)[/tex]

Step-by-step explanation:

Given

[tex](x,y) = (19,5)[/tex] --- midpoint

[tex](x_1,y_1) = (13,81)[/tex] --- end 1

Required

The other endpoint

Using midpoint formula, we have:

[tex](x,y) = 0.5 * [x_1 + x_2, y_1 + y_2][/tex]

So, we have:

[tex](19,5) = 0.5 * [13 + x_2, 81 + y_2][/tex]

Multiply both sides by 2

[tex]2 * (19,5) = 2 * 0.5 * [13 + x_2, 81 + y_2][/tex]

[tex](38,10) = [13 + x_2, 81 + y_2][/tex]

By comparison:

[tex]x_2 + 13 = 38[/tex] and [tex]y_2 + 81 = 10[/tex]

So:

[tex]x_2 = 38 - 13[/tex]

[tex]x_2 = 25[/tex]

and

[tex]y_2 = 10 - 81[/tex]

[tex]y_2 = - 71[/tex]

Henc, the other endpoint is:

[tex](25,-71)[/tex]

1. Explain why it makes sense to call the following expression a “perfect
square." *
x2 + 20x + 100

Answers

Answer:

because all sides are equal

The expression is a perfect square of (x+10)².

What is perfect square?

A perfect square is a number that can be expressed as the product of an integer by itself or as the second exponent of an integer.

For example, 25 is a perfect square because it is the product of integer 5 by itself, 5 × 5 = 25.

Given that the expression, x² + 20x + 100,

So, writing the expression as expanded form,

x·x + 2·10·x + 10·10

x² + 2·10·x + 10²

We see it is in the form of a² + 2ab + b²,

We know that, a² + 2ab + b² = (a+b)²

So,

x² + 2·10·x + 10² = (x+10)²

Hence the expression is a perfect square of (x+10)².
