Used Integration by parts; u=ln(3x-1), du=3/(3x-1) dx, dv=dx, v=x. I used the formula uv - Integral v du. I got past the long division, but I think you have to do it again? I did, and am stuck simplifying.

A car traveling at 7.0m/s accelerates 2.5m/s to reach a speed of 12.0m/s. How long does it take for this acceleration to occur?





my answer was 2.06
I divided the accelerations by the speed but I'm not sure if that was the right equation

I am very interested in chemistry and I am in AP Chemistry this year (senior in high school). I will be going off to college next year, hopefully Ohio State University, and I'm wondering if I should major in Chemistry or Chemical Engineering. So, I have a few questions.

• Which major would pay more?
• Which major would have better job opportunities right out of college?
• How do both majors differ?

Thanks for your time and input.

f(x)=(x+1)(x-2)(x-3)

I tried using the product rule with (x+1)(x-2) and getting that derivative and using the product rule again with (x-3). But im not getting a right answer.

determine if the each of the following is true of microtubules, microfilaments, or intermediate filaments.

Involved in cell transport.

I'm stuck on whether to choose microfilaments or microtubules.
I know microtubules can create cilia or flagellum, which does involve with cell transport. And microfilaments can "crawl"

Why dont we just quit the BSing around if you are not gonna be civilized like the rest of the world and all you want to do is destroy and create carnage then were just gonna have to drop a bomb and say goodbye. We have the technology right now to take over our soloar system. Not a problem. Lets quit fighting. start holding hands, giving each other big hugs and start taking care of business.

The drawing shows a baggage carousel at an airport. Your suitcase has not slid all the way down the slope and is going around at a constant speed on a circle (r = 11.8 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel is 0.760, and the angle in the drawing is 36.6°. How much time is required for your suitcase to go around once?

In a math problem, I had to simplify by combining terms. My questions was (3y+1)(-2)+y
In the end I got the wrong answer. I want to know:
(why) can I multiply the coefficient, 3, with -2 to get -6, even though -2 isn't followed by a y?
Please explain, I'm so confused.
