Find the point B on AC such that the ratio of AB to BC is 2:3
Virty [35]

Answer:

B(4, - 3 )

Step-by-step explanation:

We have A(2, - 7) and C(7, 3 )

Using the section formula to calculate the coordinates of B

x_{B} = \frac{3(2)+2(7)}{2+3} = \frac{6+14}{5} = \frac{20}{5} = 4

y_{B} = \frac{3(-7)+2(3)}{2+3} = \frac{-21+6}{5} = \frac{-15}{5} = - 3

Hence B(4, - 3 )

A cylinder has a height of 12 inches and a radius of 1.5 inches. What is its voulme? Round your answer to the nearest tenth. Use
Lerok [7]

Answer:

It's volume is of 84.78 cubic inches.

Step-by-step explanation:

Volume of a cylinder:

The volume of a cylinder with radius r and height h is given by:

V = \pi r^2h

A cylinder has a height of 12 inches and a radius of 1.5 inches.

This means that h = 12, r = 1.5

What is its volume?

V = \pi r^2h = 3.14(1.5)^2(12) = 84.78

It's volume is of 84.78 cubic inches.
