Question 298125: write the equation of the parabola in standard form. find the coordinates of points corresponding to P and Q.
*i do not really know how to explain this question but here is my work if it helps. my teacher marked it wrong and i do not know what i did wrong.
f(x)= -3x^2 - 1x - 1
P' = (-2, 3)
Q'= (-1, 0)
*my teacher circled my answer for Q. i'm confused.

Question 298215: Suppose to want to reserve a rectangular region in a large room and you have 32 ft. of masking tape. Let’s investigate how much area you can reserve with 32 ft. of masking tape and how this area changes with different lengths of sides for the rectangular region.
1) Take a guess on the dimensions of the region that would give the largest area.
2) Find the values for the table below. The column labels of base, height, and area represent the values of the base height and area of the rectangular region. Use as many different values of bases and heights as you can, but have the perimeter or the rectangular region be 32ft. The table could not be put on here but it kind of looks like this:
Base Height Area
Someone please help! Thank you!

Question 298365: A rocket is scheduled to lift off from a stage 2ft. off the ground at an initial velocity of 80ft. per sec. How long is the rocket in the air? Use 32 ft/sec as the acceleration rate of gravity(G). What will be the maximum height of the rocket? The converted formula for the height of an object propelled unto the air is h=-16t squared +vt+h sub zero... I think I have height as being 2ft, velocity is 80ft per sec h sub zero is 2ft? I'm so confused! Help! Please! Thank you, Natalie
