Answer:
Step-by-step explanation: x+ y+z=19 ...(1)
2x+6y+z=12 ...(2)
3x+8y+z=-14 ...(3)
(2)-(1) gives
x+5y =-7 ...(4)
(3)-(1) gives
2x+7y= -33 ...(5)
multiply (4) by 2
2x+10y=-14 ...(6)
(6)-(5) gives
3y=19
y=19/3
x+95/3=-7
x=7+95/3=(21+95)/3=116/3
from (1)
116/3+19/3+z=19
(116+19)/3+z=19
135/3+z=19
45+z=19
z=19-45=-26
Since t is the time after it dropped and h0 is the initial height, just substitute the things already given to you in the question
h = 1,200 - 16(2)²
h = 1,136
Therefore, the height of it then would be 1,136 feet above the ground
Answer: 3 x 6 + 5
or

Answer:
2√10
Step-by-step explanation:
Given the coordinates (-6, 2) and (0,0)
We are to find the distance between the coordinates. Using the distance formula;
d = √(x2-x1)²+(y2-y1)²
d = √(0-2)²+(0+6)²
d = √(-2)²+(6)²
d = √4+36
d = √40
d = √4*10
d = 2√10
Hence the required distance is 2√10
