The correct model of the height of rocket above water is;
h(t) = -16t² + 96t + 112
Answer:
time to reach max height = 3 seconds
h_max = 256 ft
Time to hit the water = 7 seconds
Step-by-step explanation:
We are given height of water above rocket;
h(t) = -16t² + 96t + 112
From labeling quadratic equations, we know that from the equation given, we have;
a = -16 and b = 96 and c = 112
To find the time to reach maximum height, we will use the vertex formula which is; -b/2a
t_max = -96/(2 × -16)
t_max = 3 seconds
Thus, maximum height will be at t = 3 secs
Thus;
h_max = h(3) = -16(3)² + 96(3) + 112
h_max = -144 + 288 + 112
h_max = 256 ft
Time for it to hit the water means that height is zero.
Thus;
-16t² + 96t + 112 = 0
From online quadratic formula, we have;
t = 7 seconds
Answer:
-3.03
Step-by-step explanation:
12.95 - 15.98 = -3.03
Hope that helps!
Easy! Multiply 100 by 2 and get 200. Then subtract 900 by 2, and get 700. Then you divide 700 by 2 (because there are only 2 sides left!) and BAMMMMMM there’s your answer
The answer is c hope this helps
Answer:
Step-by-step explanation:
If Asia woke up by 5:45am and her bus regularly arrives at 6:15 am, the the total amount of time Asia needs to finish up to meet the bus is time within this interval of time i.e 30mintes.
Total time taken to dress up:
Time taken to throw an outfit = 5minutes
Time taken to do her hair and make up = 2(5) = 10 minutes
Time to walk to bus stop = 5+8 = 13minutes(8 minutes longer)
Total time she took to finish up and get to the bus = 5+10+13 = 28 minutes
Since the time used by Asia is less than the 30 minutes expected of her hence she will meet the bus
