Enter your answer as ordered pair(s). If there are multiple answers, separate them with a comma.

ps. the answer would look something like: (-4+/-squa55,0)(-4-squ55,0)

Does anyone know of a website where I can graph parametric equations with TWO variables? I can only find sites that allow me to graph simple one-variable equations. Specifically, I want to graph the following:

x = V cos(24.09) sin u
y = V cos (24.09) cos u
z = V sin (24.09)

0 < u < 360
0 < V

(And no, my graphing calculator does not support this)

2. A clothing store sells a shirt costing $20 for $33 and a jacket costing $60 for $93. If the markup policy of the store for items costing over $10 is assumed to be linear, write an equation that expresses retail price R in terms of cost C (wholesale price) What does the store pay for a suit that retails for $240.

10 pts to the best answer. please show me how i got 173 and 1/3 = x + b for one equation for the first ? and 120 =x + b for another equation to #1. and my equation to the second one is y = 3/4 X + 6 and 1/3. Am I going in the right direction.

A silo has a cylindrical main section and a hemispherical roof. If the height of the main sectio is 10m, what should the radius be in order that the volume of the silo(including the part inside the roof section) is 2000 m cube.?

2. The height, length, and width of a small box are consecutive integers with the height being the smallest of the three dimensions. If the length and width are increased by 1 cm each and the height is doubled, then the volume is increased by 120cm cube. Find the dimensions of the original small box.
