Answer:
The domain is (-2,-1,) This relation is not a function because there are repeating x-values.
Step-by-step explanation:
The domain are the list of x values and x values are the first number in a given point. Ex: (0,9) x-value is 0
Answer:
what is the question
Step-by-step explanation:
Answer:
2x3y4(3)
7
=
6
/7 x3y4
Step-by-step explanation:
The answer is 6.6 because it’s the only number between 6.5 and 6.7 so 6.6 is your answer
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
