4 0

Answer:

B(x, y) = (-2, -2)

Step-by-step explanation:

Given: AB: AC (m₁: m₂) = 1 : 2, A (x₁, y₁) = (-5, 2) and B(x₂, y₂) = (4, -10)

To find: Coordinates of B (x, y)

Using section formula:

Therefore Coordinates of B (x, y) is (-2, -2).

I have 15a but I need 15b and 14
Naily [24]
14. For a prism, the volume is given by
.. V = Bh . . . . . . . . where B is the area of the base, and h is the height of the prism

For a pyramid, the volume is given by
.. V = (1/3)*Bh . . . . where B is the area of the base, and h is the height of the pyramid

The volume is proportional to the area of the base. If the dimensions of the base decrease linearly to zero at the height of the geometry as they do for pyramids and cones, then the volume formula includes a factor of 1/3.


15b. The volume of a pyramid is 1/3 that of a prism with the same base area and height.

Find the Lateral area of a square pyramid with a slant height of 22m and a base length of 8m
Kay [80]

Answer: 352 m^{2}

Step-by-step explanation:

To find the Lateral area of a square pyramid , we will follow the three steps below:

1. Find the perimeter of the base

2. Multiply the perimeter by the slant height

3. Divide the result above by 2

That is :

The lateral surface area of a regular pyramid is lateral area = perimeter of base x slant height of pyramid) ÷ 2.

Applying the formula above:

1. The base is a square , therefore the perimeter of a square is 4L , That is

Perimeter = 4(8)

Perimeter = 32m

2. Perimeter x slant height  , that is

32 x 22 = 704m

3. Dividing the result by 2 , we have :

704/2 = 352

Therefore , the Lateral area of the pyramid is 352 m^{2}

The volume V of a sphere with radius R is given by formula V=4/3 x 3.14 x r^3
Olin [163]
36(3.14) = 4/3 x 3.14 x r^3
113.04 = 4.187(r^3)
113.04/4.187 = r^3
26.997 = r^3
3√26.997 = r
r = ~3

Check: 3^3(\pi)(4/3) = 27(3.14)(4/3) = 113.04
