Answer:

I know for the fact that it's the first one but I don't know the other answer

Step-by-step explanation:

An equation of a graph is y=mx+b and the B is the y-intercept which is -2 since the line is on top of -2. mx is the rise/run of -2 which is -3/2

Hope this helps, but I don't which other equation represents the graph.

Answer:

Volume of rectangular prism in scientific notation is $2.574\cdot10^{6}$ cubic centimeters and in standard form $2574000\text{cm}^{3}$ .

Step-by-step explanation:

Since we know that volume of a rectangular prism is length*breadth*height.

Sides of our rectangular prism are given in scientific notation as $\text{length}=1.8*10^{2},$ $\text{width}=1.3*10^{2}$ and $\text{height}=1.1*10^{2}$ .

Let us substitute our values in volume formula,

$\text{ Volume of rectangular prism}=1.8\cdot 10^{2}\cdot 1.3\cdot 10^{2}\cdot 1.1\cdot 10^{2}$

Upon using exponent product property we will get,

$\text{ Volume of rectangular prism}=1.8\cdot1.3\cdot 1.1\cdot 10^{(2+2+2)}$

$\text{ Volume of rectangular prism}=2.574\cdot10^{6}\text{cm}^{3}$

Now let us convert our volume in standard form as,

$\text{ Volume of rectangular prism}=2.574\cdot1000000\text{cm}^{3}$

$\text{ Volume of rectangular prism}=2574000\text{cm}^{3}$

Therefore, volume of rectangular prism in scientific notation is $2.574\cdot10^{6}$ cubic centimeters and in standard form $2574000\text{cm}^{3}$ .

A regular decagon has 10 equal sides. An apothem is a perpendicular bisector to the side. This means 2 equal right triangle are formed on each side (20 equal right triangles) or 10 equal isosceles triangles.

Using the 10 equal isosceles triangles and A = .5(base)(height)
Base is a side and height is apothem
Area of regular decagon = 10 × .5 × 8 × 12.3 = 492.0 yd²

Answer: 492.0 yd²
