Answer: (A) 6.6 sec (B) 6.89 sec
<u>Step-by-step explanation:</u>
y = -16t² + 1700
1000 = -16t² + 1700
<u>-1700</u> <u> -1700 </u>
-700 = -16t²
<u> ÷-16 </u> <u>÷-16 </u>
43.75 = t²
√43.75 = √t²
6.6 = t
***********************************
y = -16t² + 1700
940 = -16t² + 1700
<u>-1700</u> <u> -1700 </u>
-760 = -16t²
<u> ÷-16 </u> <u>÷-16 </u>
47.5 = t²
√47.5 = √t²
6.89 = t

1st, 4th, 5th. hope this helped!
Answer:
Undefined.
Step-by-step explanation:
Slope = (y2 - y1)/(x2-x1)
Values of x are the same, so x2 - x1 = 0 - 0 = 0
Slope = (y2 - y1)/0
So, slope undefined.
For vertical line, slope is always undefined.
