The graph is discont. at x = -2 and again at x = 1.
Answer:
284/3 πx³
Step-by-step explanation:
Volume of a cylinder is expressed as shown:
V = πr²h
r is the radius of the cylinder
r = diameter/2
r = 8x/2
r = 4x
Height of the cylinder = 6x
Volume of the roll with out the hole
V = π(4x)²(6x)
V = 16x²π(6x)
V = 96πx³
The hole in the middle will be a solid sphere with diameter 2x (radius will be x)
Volume of the hole = 4/3πr³
Volume if the hole = 4/3πx³
Volume of the toilet paper roll = volume of the roll without a hole - volume of the hole
= 96πx³ - 4/3πx³
= (96-4/3)πx³
= 284/3 πx³
The maximum amount of miles that can be driven is A) 220 miles.
Angles R and O are congruent. In similar triangles, corresponding angles are congruent. O and R are both the last angle in their triangles making them corresponding.
Here, formula: 5h²
Coefficient = 5
