Because Zion has the sink of a half sphere
Answer: C. Mode
Step-by-step explanation:
Qualitative data applies to observable data such as reoccurring patterns (mode)
Quantitative data applies to numbers and numerical calculations (Mean, Median)
Answer:
90 in
Step-by-step explanation:
15 x 6 = 90 in
This is because
6 x 12 hrs = 3 days
Answer:
So first you know automatically that either side of the line is 180 degrees. So 180-155 would get you 25 degrees so you now know that y=5. we know that it is also a right angle therefore you divide 65 (x-90) by 13 and you get that x is also equal to five
Step-by-step explanation:
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
