Answer:
- 3
Step-by-step explanation:
![f(x) = 2 {x}^{3} - 6x + 1 \\ plugging \: x = - 2 \\ f( - 2) = 2( { - 2})^{3} - 6( - 2)+ 1 \\ = 2 \times ( - 8) + 12 + 1 \\ = - 16 + 13 \\ = - 3 \\ f( - 2) = - 3](https://tex.z-dn.net/?f=f%28x%29%20%3D%202%20%7Bx%7D%5E%7B3%7D%20%20-%206x%20%2B%201%20%5C%5C%20plugging%20%5C%3A%20x%20%3D%20%20-%202%20%5C%5C%20f%28%20-%202%29%20%3D%202%28%20%7B%20-%202%7D%29%5E%7B3%7D%20%20-%206%28%20-%202%29%2B%201%20%20%5C%5C%20%20%3D%202%20%5Ctimes%20%28%20-%208%29%20%2B%2012%20%2B%201%20%5C%5C%20%20%3D%20%20-%2016%20%2B%2013%20%5C%5C%20%20%3D%20%20-%203%20%5C%5C%20f%28%20-%202%29%20%3D%20%20-%203)
Answer:
<h2>231in^3</h2>
Step-by-step explanation:
We know that the volume of a sphere/globe is given as
V=4
/3πr^3
but the circumference is expressed as
C=2πr
solving for r given that C=24
24=2*3.142r
24=6.284r
r=24/6.284
r=3.8in
put r=3.6 in the expression for volume we have
V=4
/3π(3.8)^3
V=4
/3π(55
V=(220.59*3.142)/3
V=693.12/3
V=231in^3
The volume of the globe is 231in^3
If the original angle is x degrees then its supplement is 180 - x degrees.
we have the equation:-
180 - x = 3x + 20
160 = 4x
x = 40
The original angle is 40 degrees and its supplement is 140 degrees
