How would I go about finding the derivative of f(x)=ln(x)(7x-2)^3 first=ln(x) second= (7x-2)^3 Would I do first times the derivative of the second + second times the derivative of the first? If so, what is the derivative of lnx? I'm confused. Thanks for y...

I need to find the slope of the graph of the function at the given point. Function: f(theta)=4sin(theta)-(theta) Point: (0,0) I tried finding the derivative of the function at theta=0, but I got 0 for an answer. I checked the answer in the back of my book...

I need to find the integral: int:(x^2+2x+3)/(x^3+3x+9) dx I think I am supposed to use the rule: int:1/u du=ln|u|+C But I don't know what to do first. Thanks for your help! :-) Oh- and the answer the back of my book gives is (1/3)ln|x^3+3x^2+9x|+C

This is probably a really easy question, but I just don't know how to set it up. An object in equilibrium has three forces exerted on it. A 33 N force acts at 90 degrees from the x-axis and a 44 N force acts at 60 degrees. What are the magnitude and direc...

I suggest trying to repeat after someone that does have a spanish accent. Listen to spanish music for starters. It's fun and when you sing along your accent is improving! :-) Audiobooks are also a good idea. I'm sure you will get better in no time. Buena...

Try using PEMDAS to help you remember the order of operations. P-Parentheses E-Exponents M-Multiplication D-Division A-Addition S-Subtraction Do you have any parenthesis? No. Are there any exponents? No. Any Multiplication? Yes. Start there. -3*2x = -6x N...

So I would write the Vertical Asy answer... x=0+(pi)n correct? since 180=pi and it can be added "n" number of times please let me know if this is the correct notation thanks so much for your help --Corin

If nights=n and she sleeps 8 hrs for every n... then you would need to multiply 8 by the number of nights to find the total amount of sleep she got. So X total hours of sleep=8n or x=8n

Sorry in advance-- I don't know how to find the answer, but I'm willing to help all I can. First, rearrange the equation of the line to make it y=-3x-1. Since we need to find a line parallel to this one, we know it needs a slope of -3. y=-3x-1 y=mx+b m=sl...

Matter is any substance which has mass and takes up space. Since air meets these requirements, it is classified as matter. Though air may not seem to take up space, it really does. If you put a baloon full of air underwater in a tank, what happens to the...

First you have to realize that: square root 12x^3/5 and (12x^3/5)^1/2 are equal! :-) Taking the square root of a value is the same as taking the value to the 1/2 power Use this rearrangement to simplify: (12x^3/5)^1/2 Multipy the exponents... 12x^3/10 I'm...

Well for one thing, we know f(x) is equal to y. It is the original function. For f(x)=3x^2 -5 We want to find the y value when x=-4 So just plug in -4 for all the x's and get the y value. f(-4)=3(-4)^2-5 f(-4)=3(16)-5 f(-4)=48-5 f(-4)=43 f(-4)=43=the y va...

Alright. I think I might have gotten the answer. Write back and tell me if you think it's right. If you think I messed up, I'll keep trying. First use ln to rearrange the original: 4^(x+4)=5^(2x+5) ln4^(x+4)=ln5^(2x+5) Put the exponents in front because o...

Both sets of answers are correct. I only wonder if in the second one, you should have used the sq. root property. If you did it that way you would get the exact same answer. I just don't want you to get marked down for not following directions. here's how...

You're welcome. If you think about it, it makes since why you got the same answer. The way you did it was right, just not the method they were asking for. There is never just one way to do things in math. :-)

So the cars will reflect blue light, but since no blue light is being emitted, they won't look blue? Since yellow light is a combination of red and green light, no blue is involved. One will not be able to see the police cars??? Thank you for your help!!...

5. Is 81/2 in. by 10 5/8 in… Just to be clear- Also I thought 2 was 25, not 125-

Wait no I’m dumb, it was 125. 1. is 18:1 2. Is 125 3. Is 27 4. Is 8/4 = 24/12 5. Is 8 1/2 in. By 10 5/8 in. And 6. Is 20 ft. As for 7 and 8, I’m not sure… Just turn to Brainly for those.
