Answer:
a. The amplitude should be 2.
The period should be 2\pi.
b. maximum value occurs in (0,1) at x = 0
minimum value occurs in (pi,-1) at x = pi

Answer:
I am only in like 5th grade, but I'll do my best to answer this.
Step-by-step explanation:
Volume of a cylinder: πr^2h where "r" is the radius and "h" is the height
π * 4^2 because since the width is 8, half of that is the radius
π * 4^2 * 8 because you still have to multiply that by the height to find the full space inside
= π * 4^2 * 8
V ≈ 402.12 (rounded to two decimals)
It is basically 22 x 4 or the other way around 4 x 24 of which equals: 88
Answer:
Step-by-step explanation
Givens
Given Length: 3x - 8
Width: 7x
Area: 7x * (3x - 8) Remove the brackets
Area: 21x^2 - 56x
Now double the length
New Length = 2 * old length
old length = 3x - 8
New Length = 2(3x - 8) Remove the brackets
New Length = 6x - 16
The width remains as 7x
Area = New Length * width
Area = (6x - 16)*7x Remove the brackets
Area = 42x^2 - 112x
Observe
42x^2 is twice as big as 21x^2
-112x is twice as small as 56x
So the area has changed by a factor 2
