Answer
m = 10
Step-by-step explanation:
Formula:
m = (y2 - y1) / (x2 - x1) => plug in points
(-3,-5) and (2,-5)
Answer:
1/35
Step-by-step explanation:
1/3 of 10 (of means multiply)
1/3 times 10 is 10/3
1/7 of 8/12=2/21
2/21 divided by 10/3
use keep change flip
2/21 divided by 10/3 equals 2/21* 3/10
1/35 is the answer
Remember that c is the initial height. Since we the rocket is in a 99-foot cliff, c=99. Also, we know that the velocity of the rocket is 122 ft/s; therefore v=122
Lets replace the values into the the vertical motion formula to get:

Notice that the rocket hits the ground at the bottom of the cliff, which means that the final height is 99-foot bellow its original position; therefore, our final height will be h=-99
Lets replace this into our equation to get:


Now we can apply the quadratic formula

where a=-16, b=122, and c=198


or


or


or

Since the time can't be negative, we can conclude that the rocket hits the ground after 9 seconds.
The descriminant is b^2-4ac so for 26 it would be -5^2 - 4 (1) (7). The quadratic formula is -B plus or minus the square root of b squared minus 4ac over 2a
