Find an equation for the surface consisting of all points p for which the distance from p to the y-axis is half the distance from p to the xz-plane. sketch or briefly describe the surface

Let P (x,y,z) be the point in xyz plane such that the distance from p to the y axis is twice the distance from p to the xz- plane  i.e,

If d1= 2d2 ………………..(1)

But D1=√X²+Z²

d2=y

substitute d1and d2 in (1), we have  

√x²+z²= 2y

X²+y²-4y²=0

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
