it's C Alan because the 7s were the times he ride the roller-coaster 7s are close to 8s.
Answer:
0 ≤ x ≤ 10
Step-by-step explanation:
The function representing the spread of virus is:
![f(x)=20(2)^{x}](https://tex.z-dn.net/?f=f%28x%29%3D20%282%29%5E%7Bx%7D)
Where x represents the number of hours after 1:00 pm
So, at 1:00 pm "x" will be equal to 0. So the domain will start from x = 0
According to the given statement, the virus spreads from 1:00 pm to 11:00 pm. So, the number of hours starting from 1:00 pm and ending on 11:00 pm will be the Domain. 11:00 pm means 10 hours after 1:00 pm i.e. x = 10
So, the domains starts at x = 0 and ends at x = 10. Therefore, the correct answer is 0 ≤ x ≤ 10
Answer:(x,y)⇒(x-5,y+7)
0'⇒(-4,2),
P'(-2,3)
Q'(2,4)
R'(0,5)
(x,y)⇒(-x,-y)
O'((1,-5)⇒O''(-1,5)
P'(-2,3)⇒P''(2,-3)
Q'(2,4)⇒Q''(-2,-4)
R'(0,5)⇒R''(0,-5)

The radius of a sphere hides inside its absolute roundness. A sphere's radius is the length from the sphere's center to any point on its surface. The radius is an identifying trait, and from it other measurements of the sphere can be calculated, including its circumference, surface area and volume. The formula to determine the volume of a sphere is 4/3π multiplied by r, the radius, cubed, where π, or pi, is a nonterminating and nonrepeating mathematical constant commonly rounded off to 3.1416. Since we know the volume, we can plug in the other numbers to solve for the radius, r.
Multiply the volume by 3. For example, suppose the volume of the sphere is 100 cubic units. Multiplying that amount by 3 equals 300.
Divide this figure by 4π. In this example, dividing 300 by 4π gives a quotient of 23.873.
