x^2 + (π/2) x + π^2/16  = -1 + π^2/16

(x + (π/4))(x + (π/4)) = 1.4674

(x + (π/4))^2 = -0.38315

A circular pool measures 10 feet across. One cubic yard of concrete is to be used to create a circular border of uniform width around the pool. If the border is to have a depth of 3 inches, how wide will the border be?

I know that 1 cubic yard is 27 cubic feet.
I say let x = width of the border around the pool
I don't know where to go with this information.

A jumbo chocolate bar with rectangular shape measures 12 cm in length, 7 cm in width, and 3 cm in thickness. Due to escalating costs of cocoa, management decides to reduce the volume of the bar by 10%. To accomplish this reduction, management decides that the new bar should have the same 3 cm thickness, but the length and width of each should be reduced an equal number of centimeters. What should be the dimensions of the new candy bar?


This one through me into a loop.
I think this problem demands the use of the volume formula
V = length • width • height. The part about reducing the volume by 10% is confusing to me.

Can someone explain what is going on in this problem and set up the right equation for me to use?

if its symmetric about the y-axis then its even
if its symmetric about the origin then its odd

For A, I simply let x = 0 to find the y-intercept(s).
To find find x-intercept(s), I must let y = 0.


You say?


Part B


To test for symmetry with respect to the x-axis, I must replace y with with -y.


Let's see.


16(-y)^2 = 120x - 225


16y^2 = 120x - 225...I got the original equation.


Yes, it's symmetric with respect to the x-axis.


To test for symmetry with respect to the y-axis, I must let x be -x


16y^2 = 120(-x) - 225


16y^2 = -120x - 225


I say not symmetric with respect to the y-axis.


To test for symmetry with respect to the origin, I must let y be -y and x be -x.
