I have two bottles of chemicals. I know that one bottle is Copper (II) Sulfide, and the other is Copper (II) Sulfate Pentahydrate. One bottle contains blue crystals and the other bottle contains black crystals. Problem is, the bottles aren't labeled, so the question is how do I determine...
I was hoping someone could check my work for me.
Question:
A satellite is in circular orbit 600 km above the Earth's surface, where the free-fall acceleration is 8.21 m/s^2. Take the radius of the earth as 6400 km. Determine the speed of the satellite and the time required to complete one...
I am doing another lab report on motion. For this lab we used a motion detector connected to a computer to collect and display data about an object in motion. The question that I am having trouble with is how does the computer calculate velocity and acceleration based on the position data...
I'm writing a lab report and came to the following conclusion, I was hoping someone might be able to verify it for me.
The average velocity during the time interval [A,B] will be equal to the instantaneous velocity at the time (A+B)/2 if the acceleration during the time interval [A,B] is a...
I've come to a few assumtions that my text hasn't covered yet, and I was hoping someone could confirm these for me or let me know where I might be missing something.
Assuming f is an odd function and a > 0 and b > 0 and a < b:
If f'(x) > 0 on (a,b), then f'(x) < 0 on (-b,-a).
If f''(x)...
According to my text 7(x^3+4x)^6(3x^2+4) simplifies to:
7x^6(x^2+4)^6(3x^2+4)
But it seems to me it should simplify to:
7x(x^2+4)^6(3x^2+4)
What am I missing here?

This shouldn't be too hard but I'm stuck, brain is getting fried.
lim [(1+2x-x^3)-(1+2(1)-(1)^3)]/(x-1)
x->1
have gotten this far and I'm stuck:
lim (-x^3+2x-1)/(x-1)
x->1
Any help is appreciated, thx.
