Answer:
A) ![f(x)=0.2(x+2)(x-5)](https://tex.z-dn.net/?f=f%28x%29%3D0.2%28x%2B2%29%28x-5%29)
Step-by-step explanation:
The graph has x-intercepts at
and
, so our factors for the polynomial will be
and
. This means we can rule out options B and D.
Our graph also has a y-intercept of
when
, so if we let
and
, we can find the multiplier:
![f(x)=a(x+2)(x-5)\\-2=a(0+2)(0-5)\\-2=a(2)(-5)\\-2=-10a\\\frac{1}{5}=a\\0.2=a](https://tex.z-dn.net/?f=f%28x%29%3Da%28x%2B2%29%28x-5%29%5C%5C-2%3Da%280%2B2%29%280-5%29%5C%5C-2%3Da%282%29%28-5%29%5C%5C-2%3D-10a%5C%5C%5Cfrac%7B1%7D%7B5%7D%3Da%5C%5C0.2%3Da)
Thus, the correct equation is A) ![f(x)=0.2(x+2)(x-5)](https://tex.z-dn.net/?f=f%28x%29%3D0.2%28x%2B2%29%28x-5%29)
< 1 and < 2 are vertical angles...because they are opposite angles made by two intersecting lines
< 3 and < 4 are adjacent....because they have a common side and a common vertex
Answer:
To find the area of the rectangular sides, use the formula A = lw
To find the area of the triangular faces, use the formula A = 1/2bh,
Step-by-step explanation:
1st formula where A = area, l = length, and h = height.
2nd formula where A = area, b = base, and h = height.
