The correct answer is Choice D.
The equation y = kx is a proportional graph. It means that you multiply x by a number and you have k.
The point (0, 0) will always be on the graph, because no matter what K is, if you are multiplying by 0 for x, you will get 0 for y.
Using the exponential function, it is found that the oxygen level at 10 miles is of 59.87 ppm.
<h3>What is the exponential function for the oxygen levels?</h3>
The oxygen levels in ppm for an altitude of x miles at the Mount Everest is given by the following exponential function:
In this problem, the altitude is of x = 10 miles, hence the oxygen level in ppm is of:

Answer:
Total cost= $39
Step-by-step explanation:
Giving the following information:
At the theater, they sell a bag of popcorn for $5.50 and a drink for $3.75.
<u>First, we will establish the total cost formula:</u>
Total cost= 5.5p + 3.75d
p= number of bags of popcorn
d= number of drinks
<u>Now, for 3 bags and 6 drinks:</u>
Total cost= 5.5*3 + 3.75*6
Total cost= $39
