Answer:
666 ft
Step-by-step explanation:
The circumference of the wheel is given by the formula ...
C = 2πr
For a radius of 106 ft, the circumference is ...
C = 2(3.14)(106 ft) = 665.68 ft
Sabrina traveled about 666 feet in one revolution.

Answer:
1430 m
Step-by-step explanation:
1 km = 1000 m
3000 cm = 30 m
1000 + 400 + 30 = 1430
Answer:

Step-by-step explanation:
In this problem we have a exponential function of the form

where
x is the time in hours
y is the numbers of bacteria
a is the initial value
b is the base
r is the rate of growth
b=(1+r)
we have that

For x=8, y=3,300
substitute in the exponential function

solve for b

![b=\sqrt[8]{1.1}](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B8%5D%7B1.1%7D)

Find the value of r

The equation is equal to

For x=12 hours
substitute the value of x in the equation
