5th Grade student teacher: Needs ur help....
What fun activity could I use to to teach 5th grade students about the Constitution?

9th
6a+4 = -8 6a = -8-4 a = -12/6 a = -2

4th grade math
The sum of two numbers times a third number is equal to the sum of each added number times the third number. For example 4 * (6 + 3) = 4*6 + 4*3.

Calculus
Use the quotient law where you find the derivative of f(x)*g(x)-the derivative of g(x)*f(x) and the whole thing divided by g(x). (x+2)(x^3+x-2)' - (x+2)'(x^3+x-2) ---------------------------------- (x^3+x-2)^2 (x+2)(3x^2+1) - 1(x^3+x-2) --------------------------------...

Thank you so much for all the calculus help! I felt more prepared for the exam!

Calc again sorry
4) The graph of y = (x)/(1+25x^2) for x is greater than or equal to 0 has a horizontal tangent at x = what. So what I did was find the first derivative. I did the quotient rule and ended up with x50x - 1+25x^2 --------------- (1+25x^2)^2 I equated that with 0 but I don't k...

Calculus
How do you do this question. f(x) = (5x-1)/(2-3x), find f^(-1)(x). The answer is supposed to be (1+2x)/(5+3x). -------------------------------------- And can you please explain this one to me. Suppose that xy^(3)+2y^(2)+xy+2x^(3) = 0. Find the general expression for dy/dx. Als...

Don't you have to do implicit differentiation?

Thanks so much!

Find the line which passes through the point (0, 1/4) and is tangent to the curve y=x^3 at some point. So I found the derivative which is 3x^2. Let (a, a3) be the point of tangency. 3x^2 = (a3 - 1/4)/(a-0) I'm not sure how to solve for a. Yes, the point is (0,1/4) but it&#...

Calculus part 3 so sorry
y = e^2xsin3x Find the derivative. So I used the product rule and I got sin3x(e^2x)+cos^3x(e^2x). But the actual answer is sin3x(2e^2x)+cos^3x(3e^2x) Where the the 2 and 3 before the e come from?

Calculus Part 2
y = tan(sqrtx) Find dy/dx. So I found it and I got the answer as sec^2(sqrtx) but the answer is (sec^2(sqrtx))/2(sqrtx)...why? ---------------------------------- 2) Find the line which passes through the point (0, 1/4) and is tangent to the curve y=x^3 at some point. So I foun...

Calculus questions..really need help, please!
1) Find the value of the lim(x->0) ((sin5x/sin2x)-(sin3x-4x)). I have no idea where to start so if someone could start it off for me it would really help. 2) If f(x) = (2x-3)/(5x+4) then what's the inverse of f(x) So I replaced x with y x = (2y-3)/(5y-3) Now am I suppos...

Can someone explain the method of implicit differentiation to me. I know that we differentiation both sides of the equation with respect to x (I don't understand what they mean by with respect to x). And then y is a function of x...I don't understand what that means. F...
