Answer:

y=7x-47

Step-by-step explanation:

(8, 9) = (x_1,y_1) \\ m = 7 \\ y  - y_1 = m(x - x _1) \\ y - 9 = 7(x - 8)

y - 9 = 7x - 56 \\ y = 7x - 56 + 9 \\ y = 7x - 47

AleksAgata [21]

Answer:

50.2

Step-by-step explanation:

ut =  \sqrt{ {6}^{2}  +  {5}^{2} }   \\  \sqrt{36 + 25}  \\  \sqrt{61 }  \\ using \: cosine \: rule \\ cos \: u =  \frac{ {5}^{2} + 61 - 36 }{2 \times 5 \times  \sqrt{61} }  \\  \\  =  \frac{25 + 61 - 36}{78}  \\  \\  = \frac{50}{78 }  \\  \cos \: u = 0.64 \\ m \:u = 50.2

A block of wood is 2.5 feet long, 0.5 feet wide, and 0.25 feet tall. It weighs 16.5 pounds.
AysviL [449]

Answer:

Density = 52.8 pound per cubic feet.

Step-by-step explanation:

Given the following data;

Length = 2.5 feet

Width = 0.5 feet

Height = 0.25 feet

Mass = 16.5 pound

To find the density of the wood;

First of all, we would determine the volume of the wood.

Volume = length * width * height

Volume = 2.5 * 0.5 * 0.25

Volume = 0.3125 cubic feet

Next, we find the density;

Mathematically, density is given by the formula;

Density = mass/volume

Substituting into the formula, we have;

Density = 16.5/0.3125

Density = 52.8 pound per cubic feet.
