what is the amount of heat lost in KJ for 50 ml of water going from 70.0 degrees C to 1.0 degrees?

physics
An automobile starts from rest and accelerates to a final velocity in two stages along a straight road. Each stage occupies the same amount of time. In stage 1, the magnitude of the car's acceleration is 3.5 m/s2. The magnitude of the car's velocity at the end of stage...

algebra
How do you find any x-intercepts and y-intercepts. If no x-intercepts exist, state this. g(x)=2x^2+3x-1

Chemistry II
What is the vapor pressure of benzene at 23◦C (about room tempera- ture)? The normal boiling point of benzene is 80◦C and its molar heat of vaporization is 30.8 kJ/mol.

WHAT IS A PUZZLE

So the funtion is: x^2(x - 7)(x + 3 - 5i)(x - 3 + 5i) For it to have rational coefficients, you must get rid of the -3 + 5i term. Therefore the remaining zero is: 3 - 5i so your answer would be (C)

math
solve the system of equation by graphing then classify the system as consistent or inconsistent and as dependent or independent 8x-4y=-20 4y-8x=-20

math
you know you are right i did forget to change the symbol sorry so the answer is x>40 or x >-40 because negative and negative is negative i'm i right.

math
Solve -0.6x < -24 x=-40 the solution is {x|<-40} do it have it right!!!
