A particle is traveling along a straight line, and its distance from the original is given by the equation:

s(t)=t^3 +12t^2 +36t + 4
where t is greater than or equal to 0.

a. What is the average velocity of the particle on the interval [3, 6] ?

b. Find c in [3, 6] so the velocity at c is equal to the average velocity you found in the pervious question.

c.When is the particle's acceleration positive? negative?

d. When is the particle speeding up? slowing down?

CAN YOU PLEASE PROVIDE WORK so i understand how to do it myself next time?! thanksss a bunch!

T(x,y) = (x^2, y)
Using the fact that T(u + v) = T(u) + T(v) must hold for it to be a linear operator, I reasoned that this transformation is not a linear operator. However, I would like confirmation on this simply because my prof is horrible and I do not know if I applied the property correctly.

My teacher help me with this math question but he didn't have enough time to explain it please help me

it's about substitution

y= x-8
y= -1/3x-4

x-8= -1/3x-4

1/3x= -4+8

this is the part I don't understand. Out of nowhere he got
4/3x = 4
can you please explain to me how my teacher got this? Thanks

4x^2 + 9y^2 - 8x + 36y + 4 = 0
I know I have to move the 4 over
4x^2 + 9y^2 - 8x + 36y = -4
And then factor:
4(x^2 - 2x) + 9(y^2 + 4y) = -4
and find (-2/2)^2 & (4/2)^2 = 1 & 4 (add to left side and 4 & 36 to the right).

Where do I go from here and how to I find the center, foci, major & minor axis?

I really appreciate ANY help.
Thank you very much and Merry Christmas!

So I was trying to use the derivative of y=3x^2, which is y'=6x. Plug x=2 into that so the slope at x=2 is 12. I actually have no clue if that's right or not. Anyway, I'm pretty clueless after that anyway... thanks for the help in advance.

The bottom and top of a box are rectangles twice as long as they are wide. Find the volume of the box if it is 4 ft high and has a total surface area of 220 ft^2. Which equation can you use to solve this problem?


4w^2 + 8w = 220

4w^2 –16w = 220

4w^2 + 24w = 220

4w^2 –24w = 220
