• ### Volume of Solid rotating calc question, am i doing it right?

Can someone tell me if Im doing this right?

So for part a, i think the answer would be the integral of (2-8-x^2)^2 - (2-x^2)^2 times pi from -2 to 2.

Im not sure how to do b or c so can someone explain that part?

• ### Calc question?

Write the three different ways we could find the EXACT area under 𝑓(𝑥) = 𝑒^𝑥^3 on any interval [a,b].

I tried working on it and the only way I could figure out was was the integral way. I didn't know there were more so can someone help?

What is a word you would use to describe Bianca's marriage to Lucentio and why? Do they seem like they have a "companionate" marriage? Why or why not? Be as specific as possible in your explanations, using textual details/quotation to back up your points.

What is a word you would use to describe Katherine and Petruchio's marriage in these acts and why? Do you think the two end up having a "companionate" marriage or not? Be as specific as possible in your explanations, using textual details/quotation to back up your points.

ive been working on this problem for two hours and have one attempt left can someone please help??

• ### calc question?

can someone walk me through this? thanks

The region bounded by the given curves is rotated about the specified axis. Find the volume V of the resulting solid by any method.

y = −x2 + 17x − 72, y = 0; about the y−axis

Find the volume V of the solid obtained by rotating the region bounded by the graphs of the given expressions about the specified line.

y = 27x^3, y = 0, x = 1; about x = 2

i got 571pi/7 and 90337pi/7 for both tries and they were both wrong. Can someone explain to me how to do this?

A certain chemical reaction releases 423.kJ of heat energy per mole of reactant consumed. Suppose some moles of the reactant are put into a calorimeter (a device for measuring heat flow). It takes 2.79J of heat energy to raise the temperature of this calorimeter by 1°C. Now the reaction is run until all the reactant is gone, and the temperature of the calorimeter is found to rise by 12.9°C. How would you calculate the number of moles of reactant that were consumed?

Set the math up. But don't do any of it. Just leave your answer as a math expression.

Calculate the mass of diphosphorus pentoxide P2O5 that contains a million ×1.00106 phosphorus atoms.

Be sure your answer has a unit symbol if necessary, and round it to 3 significant digits.
