Answer:
14
Step-by-step explanation:
you can simplify it by turning a²+b²/a-b
into
(a-b)²+2ab / a-b
eliminate the fraction
a-b +2ab
a=-1
b=-5
-1-(-5)+2*-1*-5
-1+5+10 = 14

Answer:
Step-by-step explanation:
Eek! Let's give this a go. Things we know:
acceleration of Bond in free fall is -9.8 m/s/s
velocity of the truck is 25 m/s
displacement Bond will travel when he jumps is -10 m
What we are looking for is the time it will take him to hit the top of the truck, knowing that the truck can travel from one pole to the next in 1 second.
Our displacement equation is
Δx = v₀t + 1/2at²
Filling in we have

Simplifying we get

This is a quadratic that needs to be solved however you personally solve quadratics. When you do that, you find that the times it will take Bond to drop that displacement is either -.37 seconds or 5.47 seconds. Many things in physics can be negative, like velocity and acceleration, but time NEVER will be. So it takes Bond 5.5 seconds to drop to the roof of the moving truck. That means that he needs to jump when the truck is between the 5th and the 6th poles away from him.
Good luck with this!
Cheers!
Answer:
Step-by-step explanation:
You could talk about how how or low it goes.
For instance: if the graph was going very high then suddenly low you could say that it was going very high until it suddenly dropped.
