Independent variable on x-axis (value you can choose)
dependent variable on y-axis (corresponding value for the value you have chosen)
You can the hours and the distance traveled is a function of those hours.
also, I'd go in increments of 5. More accurate than increments of 15. The answer is D! <span><span>

Answer:
XY = 23.3 ft
Step-by-step explanation:
It helps if you can draw yourself a picture.
You are given right triangle with the adjacent side of the 9° angle and you are looking for the hypotenuse.
The cos of an angle = adjacent side/hypotnuse
Let h = XY
Then cos 9 = 23/h
h cos 9 = 23
h = 23/cos 9
h = 23.3 ft.
Answer:
0.205177 mi
Step-by-step explanation:
Step 1: Find conversions
12 in = 1 ft
5280 ft = 1 mi
Step 2: Use Dimensional Analysis
0.205177 mi
#3)A=L x W
11 7\8=L=4 3\4 x W
11 7\8-4 3\4=w
7 1\8=w
w=
#4)120 x 1.75=210
answer=D

Answer:
The size of the sample after four hours is of 3158 bacteria.
Step-by-step explanation:
The population after t hours can be modeled by the continuous exponential growth model, which is:
In which P(0) is the initial population and r is the growth rate paremeter.
A growth rate parameter of 17% per hour.
This means that
Suppose also that a sample culture of 1600 is obtained from this population.
This means that
Find the size of the sample after four hours.
This is P(4).
Rounding to the nearest integer
The size of the sample after four hours is of 3158 bacteria.
