Answer:
6.5 seconds
Step-by-step explanation:
Ok so the equation you gave is -16T^2 + 676 in the comments which is what I'll be using for this problem. The problem is really just asking you to find the zeroes of the equation excluding any negative solutions since that doesn't really represent anything in this context since T is time.
So the first step is to set the equation equal to 0
.
Subtract 676 from both equations.

Divide both sides by -16

Take the square root of both sides

Ignore the negative and take only the positive solution, since in this context it doesn't make much sense. So after 6.5 seconds the height is 0, meaning it hits the ground after 6.5 seconds.
Answer:
C
Step-by-step explanation:
the mode is the value or values that occur most often in the data set
here 5, 12, 150 all occur 3 times
the mode is then 5, 12, 150
that is there are 3 modes for this data set
15
i think not sure sorry if i got it wrong but ya
To answer this you will need to write the ratio of difference in the tides over the amount of time that goes by.
1. 3.21 ft - 0.20 ft= 3.01 ft change.
2. 3.01 change over 6 5/12 hr.
3. Divide these to find the lapse rate per hour. This is about 0.47 ft per hour.
