16.935 I got a question on a test hope this helps):
Answer:
Therefore the angle of intersection is
Step-by-step explanation:
Angle at the intersection point of two carve is the angle of the tangents at that point.
Given,
and
To find the tangent of a carve , we have to differentiate the carve.
The tangent at (0,0,0) is [ since the intersection point is (0,0,0)]
[ putting t= 0]
Again,
The tangent at (0,0,0) is
[ putting t= 0]
If θ is angle between tangent, then
Therefore the angle of intersection is .
350 / 28 = 12.5 gallons, so 13 gallons needed
13 X 2.5 = $32.50
What are the conclusions?
I would assume that even though both hot chocolate and coffee increased and decreased at the same time, they are not a correlation since one doesn’t cause the other to increase/decrease
Answer:
first box is parallel
Second box perpendicular
Third box neither
Fourth box neither
Fifth box perpendicular
Sixth box is parallel
Why? Slopes of parallel lines are the same. Slopes of perpendicular lines are opposite reciprocals. (Example slope=1/2 a perpendicular line would be -2/1). Neither is just a when it’s not either parallel or perpendicular.
Hope this helps
