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.
What type of question is this
Answer:
The width is 10 inches
Step-by-step explanation:
Perimeter = 2(Length + Breadth)
Length(L) = 3B + 5
Perimeter = 70
70 = 2(3B + 5)
70 = 6B + 10
70 - 10 = 6B
60 = 6B
60/6 = B
B = 10 inches
Answer:
213 points
The y-intercept is how many points Jackson already scored, and the slope is how many points he is scoring every game.
Step-by-step explanation:
Jackson earns 28 points per game, so after 6 games, he earns 168 points (just multiply 6 by 28). He already scored 45 points, so if you add them together, he scored a total of 213 points.
The y-intercept is 45, what he already scored, and the slope is 28, how many points he scores per game.
