Is it like y=1/8-8 . How did you get 125

Math
Which slope would be steeper : 8 or 1/8

Physics
ok so i see what i did wrong and got a value of 2276308.355 J

Physics
A roller coaster is at the top of a 98.2 m hill and has a mass of 1831.0 kg. It is traveling at a velocity of 23.7 m/s. What is the coaster car's TOTAL energy? I took the eg=1/2mv^2 and plugged in (1831)(9.8)(98.2) and got 1762081.16 I then took the ek= 1/2mv^2 and plugged...

I dont know where to begin with this one because I dont recall my teacher giving us a formula for it. A baby carriage is sitting at the top of a hill that is 22.1 m high. The carriage with the baby weighs 15.8 N. What is the Ep for the carriage and baby in relation to the bott...

Physics
well my teacher does not require that and when we went over problems similar to this, it was expanded out the way i have it now.

Physics
I just wanna check if i am right. A car is traveling with a velocity of 42.3 m/s and has a mass of 2183.0 kg. Find the Ek of the car. i used the ek=1/2mv^2 and plugged everything in to get a total of 1953010.035 J .. is that right?

Calculus
Use the table of values to estimate ⌠6 ⎮ f(x)⋅dx ⌡0 Use three sub intervals and the (a) left endpoints, (b) right endpoints, and (c) midpoints. If f is an increasing function, how does each estimate compare with the actual value? Explain your reasoning....

Calculus
Give an example of a function that is integrable on the interval [-1,1], but not continuous on [-1,1].
