COLLEGE CALCULUS.
Use implicit differentiation to find the equation of the tangent line to the curve xy^3+xy=5 at the point (4,1) . The equation of this tangent line can be written in the form y = mx+b where m is:? and where b is:?

Chemistry
Perform the following calculations to the correct number of significant figures. (89.6-23.981)/0.0047

physics
F(along radius) = ma μmg=mv²/r μg=v²/r μgr=v² v²=(0.590)(9.80)(36.5) v ~= 14.5m/s

math
at the beginning of the week a particular stock sold for 29 3/8 per share. at the end of the same week it sold for 31 2/8. what was the amount of inctrease per share?

105 miles

Chemistry
All I know is that Marcus is wrong because solids don't have to become liquids before they become gas. That is what is the case with dry ice. It becomes a gas before it has the time to go to a liquid.

Calculus
For f(x)=lnx, construct tables, rounded to four decimals, near x=1, x=2, x=5, and x=10. Use tables to estimate f'(1), f'(2), f'(5) and f'(10). Then guess a general formula for f'(x).

Calc
Use a graph to estimate the limit: lim θ->0 (sin(5θ)/θ) Note: θ is measured in radians. All angles will be in radians in this class unless otherwise specified. I tried graphing it on my calculator but the limit I got is incorrect.

Calc
Sorry! That was a typo. It was as the limit approaches 4. I'm still confused on how to find the y intervals.
