Answer:
C. The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.
Step-by-step explanation:
If t=3 or t=6 take the 3 and replace it for t. d(3)= 4.9(3)^2= 44.1 so with that answered you can now narrow the answer down to A. and C. so if we go back to the question the coin was dropped from the top of a building that then narrows it down to C.

Answer:
B. $10
Step-by-step explanation:
Using technology, the linear regression equation by fitting the data in the table is ŷ = 2.4x + 11. The predicted number of hits they will be recorded on day 15 is 47.
Using technology such as a regression calculator or excel ;
The regression equation which models the data is ;
- <em>Slope</em><em> </em><em>=</em><em> </em><em>2.4</em><em> </em><em>;</em><em> </em><em>intercept</em><em> </em><em>=</em><em> </em><em>11</em><em> </em>
<u>The</u><u> </u><u>number</u><u> </u><u>of</u><u> </u><u>hits</u><u> </u><u>recorded</u><u> </u><u>on</u><u> </u><u>day</u><u> </u><u>15</u><u> </u><u>:</u>
<u>Substitute x = 15 into the equation</u> :
ŷ = 2.4(15) + 11
ŷ = 47
Therefore, the predicted number of hits on day 15 is 47 hits.
