Okay, the first step to answering this probelm is finding the slope of this line. 
The equation for slope is 
y₂-y₁
-------
x₂-x₁
Plug the points in 
-2 - 0       -2              1
------- = --------- = -  ------- (negative 1/5) 
10 - 0       10             5
 Now we will use the point slope equation 
y - y₁ = m(x- x₁)
Lets use the point (10,-2)
Plug in the x,y, and your new slope- then simplify 
y +2 = -1/5(x -10)
y + 2 = -1/5x + 2
y = -1/5x 

That's your final equation!

What is the volume of this triangular prism?
Liula [17]

Answer:

5676.16 cm^3

Step-by-step explanation:

The volume of any prism is given by the formula ...

V = Bh

where B is the area of one of the parallel bases and h is the perpendicular distance between them. Here, the base is a triangle, so its area will be ...

B = 1/2·bh

where the b and h in this formula are the base and height of the triangle, 28 cm and 22.4 cm.

Then the volume is ...

V = (1/2·(28 cm)(22.4 cm))·(18.1 cm) = 5676.16 cm^3

_____

You will note that this is half the product of the three dimensions, so is half the volume of a cuboid with those dimensions. Perhaps you can see that if you took another such prism and placed the faces having the largest area against each other, you would have a cuboid of the dimensions shown.

aleksandrvk [35]

Answer:

16 units

Step-by-step explanation:

period = length of an interval that contains exactly one copy of the repeating pattern, so from one peak to another peak.
