Answer: The Ferris wheel’s speed in feet per hour.
Step-by-step explanation:
The volume of the cylinder is between 5 and 6 gallons.
<h3>What is the volume of the cylinder?</h3>
A cylinder is a three-dimensional shape that is made up of a prism with a circular base.
Volume of a cylinder = nr^2h
Where:
- h = height
- n = 22/7
- r = radius
22/7 x 28 x (15^2) = 19,800 cubic centimeters
First convert the volume to liters = 19,800 / 1000 = 19.8
Now convert to gallons = 19.8 / 3.785 = 5.23 gallons

Answer:
D. 10 miles
Step-by-step explanation:
As you know 2 inches=5miles so if you add 2 more inches that is equal to 5 miles you will have to add 5 and 5 which equal 10 miles.

Answer:
x = {nπ -π/4, (4nπ -π)/16}
Step-by-step explanation:
It can be helpful to make use of the identities for angle sums and differences to rewrite the sum:
cos(3x) +sin(5x) = cos(4x -x) +sin(4x +x)
= cos(4x)cos(x) +sin(4x)sin(x) +sin(4x)cos(x) +cos(4x)sin(x)
= sin(x)(sin(4x) +cos(4x)) +cos(x)(sin(4x) +cos(4x))
= (sin(x) +cos(x))·(sin(4x) +cos(4x))
Each of the sums in this product is of the same form, so each can be simplified using the identity ...
sin(x) +cos(x) = √2·sin(x +π/4)
Then the given equation can be rewritten as ...
cos(3x) +sin(5x) = 0
2·sin(x +π/4)·sin(4x +π/4) = 0
Of course sin(x) = 0 for x = n·π, so these factors are zero when ...
sin(x +π/4) = 0 ⇒ x = nπ -π/4
sin(4x +π/4) = 0 ⇒ x = (nπ -π/4)/4 = (4nπ -π)/16
The solutions are ...
x ∈ {(n-1)π/4, (4n-1)π/16} . . . . . for any integer n
