The equation on number 3 is showing that Henry hikes 0.5 miles per hour, with x = number of hours. The graph shows that Clark hikes 15 miles in 10 hours, or 1.5 miles per hour. Clark is faster because of the reasons listed above.

Problem 4 is strange because it has a different value from x = 1 to x = 4 than it does for x = 5 and above, but my best guess would be a piecewise function:
If x < or equal to 4, 15x. If x > 4, 10 × (x - 4) + 60.

Problem 5 is much simpler: because x goes up 16 every time y goes up 6, 6/16 × x or (6/16)x.

1. Two students conducted similar experiments. The results of their experiments are
padilas [110]

Answer: D. Replicate the experiment to see whose results are more reliable.

Step-by-step explanation:

The experiments are similar, then we should expect to see similar results.

Now, we know that they get different results, let's analyze the options:

A) With the given information we can not conclude which is the incorrect experiment, then this is discarded.

B) We can not really determine that both students are in correct only knowing the experiment and the results, so this is also discarded.

C) You can not assume things.

D) This is the correct option, an experiment must be repeatable. This means that, with the same conditions, the result must be always the same.

Then we can replicate both experiments and see if the results are the same as before to determine if the results are reliable.

Which equation is represented by the graph below?
denpristay [2]

Answer:

D

Step-by-step explanation:

I assume that for C and D, you meant e^x.

Since the function is defined at 0, eliminate A and B (since ln 0 is undefined)

Between C and D, we know that when x=0, e^x = 1. Since the y intercept of the graph is -3, this means the equation is y = e^x - 4.
