Her home was 2 km 691 m from the store. (5 km = 5000m --> 5000-2309)
For this case we have the following function:

We can rewrite the function to identify the zeros of it.
When rewriting the function factoring we have:

Therefore, the zeros of the function are:

Thus, the graph that contains intersections on the x axis in the points mentioned, will be the graph of the function.
Answer:
See attached image.
Answer:
12,600mg per 21 days
Step-by-step explanation:
200mg three times a day → (200mg)(3) = 600mg per a day
21 days → (21)(600mg) = 12,600mg per 21 days
2x+7x=747
9x=747
x=83
83(2) = 166
83(7) = 581
Answer:
The of depression between the cliff and the boat is 48.74 degrees.
Step-by-step explanation:
We have,
Height of the cliff is 200 foot
Distance of boat from the cliff is 175 feet
It is required to find the angle of depression between the cliff and the boat.
Here, 200 foot is perpendicular distance and 175 is base.
Using trigonometry :

So, the of depression between the cliff and the boat is 48.74 degrees.
