Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
y=-16x^2+129x+119
y=−16x
2
+129x+119
Try looking at this steps, I hope this helps!
Answer:
The expression is: 100 -a - 2b
Step-by-step explanation:
One piece of length a and two pieces of length b, i.e., (2 times b) are a total length of (a + 2b). We are asked to express the remaining part of the wire, originally 100 cm long, so that must be 100 minus the total pieces cut out:
100 - ( a + 2b ) = 100 -a -2b
I didnt have room for 7 so ill just write it here
20O-12x<60
-12x<-140
X>11.6666..or 11 2/3
