Answer:
Step-by-step explanation:
In order to find out how long it takes for the rocket to hit the ground, we only need set that position equation equal to 0 (that's how high something is off the ground when it is sitting ON the ground) and factor to solve for t:
Factor that however you are factoring in class to get
t = -3.1 seconds and t = 25.9 seconds.
Since time can NEVER be negative, it takes the rocket approximately 26 seconds to hit the ground.
Answer:
x=3
Step-by-step explanation:
for 17.
we have that x=8 as one solution
then we have
x-8=0
so we know that
so we divide and get that
and we can factor it as
so the other solutions are
x-3 =0
x = 3
this is a normal division
Answer:28
Step-by-step explanation: in this case n=4, so you would plug in 4 into the equation: 5(4)+8 which equals 8
Answer:
25/36
Step-by-step explanation:
(2^-1 + 3^-1)^2
➡
➡
(1/2 + 1/3)^2
➡
(5/6)^2 = 25/36
Answer:
340.65
Step-by-step explanation: Add 84.79+44.75+18.66=148.2
