Answer:
Step-by-step explanation:
so when the height is zero, that's when the rocket hits the ground. The equation will have two zeros, but one would be for a negative time, or before the rocket is launched. so we only one the one after the rocket is launched.
use the quadratic formula to solve for x ( which is time)
-124 +- sqrt [ 
- 4*(-16)*(127) ] / 2 (-16)
-124 +- sqrt [15376 + 8128 ] / -32
-124 +- sqrt [23504 ] / -32
-124 +- 153.310 / -32
if we take the positive part it will become the negative time so skip that one try the negative part 1st
-124 - 153.310 / -32
-277.310 / -32
8.6659 seconds to hit the ground. ( time of flight) aka TOF
8.67 seconds ( rounded to nearest 100th)
Answer:
B.) IH = IJ = 3 and JK = HK = StartRoot 29 EndRoot, and IH ≠ JK and IJ ≠ HK.
Step-by-step explanation:
Answer:
no it is not an integer
Step-by-step explanation:
nope.
Integers are whole numbers that are not fractions.
this is not the case in -22.96 as the decimal 0.96 constitutes the faction component of the number

Answer:
x = 4
Step-by-step explanation:
2(4x + 3) = 10x - 2
2 × 4x + 2 × 3 = 10x - 2
8x + 6 = 10x - 2
8x - 10x = - 6 - 2
- 2x = - 8
2x = 8
x = 8/2
x = 4
