Answer:
a quadratic function
Step-by-step explanation:
A quadratic function is a second-degree polynomialfunction, and when graphed is called a parabola.
To solve, you need to find the least common multiple of the denominator.
In this case, its 30.
3*9= 27/30
1*10 = 10/30
She walked 37/30 miles or 1 mile and 7/30th of a mile
Answer:
The hourly growth rate is of 4.43%.
The function showing the number of bacteria after t hours is 
Step-by-step explanation:
Equation of population growth:
The equation for the population after t hours is given by:

In which P(0) is the initial population and r is the growth rate, as a decimal.
The conditions are such that the number of bacteria is able to double every 16 hours.
This means that
. We use this to find r.



![\sqrt[16]{(1+r)^{16}} = \sqrt[16]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B16%5D%7B%281%2Br%29%5E%7B16%7D%7D%20%3D%20%5Csqrt%5B16%5D%7B2%7D)




The hourly growth rate is of 4.43%.
80 bacteria are placed in a petri dish.
This means that
.



The function showing the number of bacteria after t hours is 
Answer:
3.5 inches
Step-by-step explanation:
create a proportion:
inches / miles = inches / miles
let 'x' = distance in inches
<u>1/4</u> = <u> x </u>
18 252
18x = 252(1/4)
18x = 63
x = 63 / 18
x = 3.5
