Answer:
<h2>YES. These points are collinear.</h2>
Step-by-step explanation:
If three points are collinear, then the slopes are the same.
The formula of a slope:
For (0, -10) and (-3, -13):
For (-3, -13) and (2, -8):
We can check the last pair (0, -10) and (2, -8):
The answer is 225

Answer:
5 years
Step-by-step explanation:
The shorter tree is 5 ft shorter, but is growing 1 ft/year faster. It will make up the difference of 5 ft in (5 ft)/(1 ft/year) = 5 years.
The volume of a cone is 1/3 pi r^2 h. So by substitution, V = 1/3 of 80pi which simplifies to V=26.667pi, which when multiplied out, provides the answer V = 83.8 cubic meters.
