Lets get started :)
Referring to the picture I have uploaded might help you
We have the same base, which in this case is x.
When multiplication occurs in the same base, we add the powers

↓ (I am going to perform the problem separately and then give the final answer as the power to x)

=

↓
x²

The power of a power should be performed by multiplying the powers together.
2 x

=


Your final answer will be the second option
Answer:

b) 
c) 628 feet
Step-by-step explanation:
We are given the following in question:
Diameter of Ferris Wheel = 200 feet
a) Distance around Ferris wheel
The distance around Ferris wheel is given by the circumference of Ferris wheel.
b) Formula to calculate circumference

where d is the diameter of he wheel.
c) Distance traveled in one rotation
This will be given by the circumference of the Ferris wheel.

Thus, the distance traveled in one rotation is 628 feet.
Step-by-step explanation:
in x ,y =0
in y ,x =0
i think its thik ok dont mind if its wrong
It is given that the bacteria in a colony doubles every 8 hours.
To find the population of bacteria 24 hours from now, we need to find the population of bacteria after every 8 hours.
The present population of the bacteria is 9315.
After 8 hours, the bacteria becomes double. So, the number of bacteria becomes 9315 x 2 = 18630.
Again after 8 hours, the bacteria becomes 18630 x 2 = 37260.
Again after 8 hours, the bacteria becomes 37260 x 2 = 74520.
Thus, after 24 hours from now, the population of the bacteria is 74520.
