If x is the mean proportional of 4 and 9, then x could be....._______?
choices:
a)4
b)3
c)6
d)36
didnt kno how to solve this, HOW do you solve this?-a:b:c
Here, b is the mean proportional. The fo
1/x=1/2+2/x
Please show steps!
Thanks!!(:-1/x=1/2+2/x
isolate x to get all x terms on one side
1/x - 2/x=1/2
combine like terms
-1/x=1/2
1/x=-1/2
cross multiply
-x=2
x=-2-1/x = 1/2 + 2/x

The height if a cone is decreeing at 3cm/s while its radius is increasing at 2cm/s . When the radius is 4cmand the height is 6cm , is the volume of the cone increasing or deceasing? At what rate is th
50 times 2 2/9 = 111.11
(the 2/9 is a fraction)
like I cant put that into a calculator. 50 times 2 is 100.
how do you times 50 and 2 2/9 to equal 111.11?-First convert the 2 2/9 to an improper fract
I never found this type of equations before. If someone could tell me how they are solved and hopefully even tell me whats the name of this type of equation so I can check it into google or something.
So Ive completely forgotten everything about conic sections since this last summer where I took Calc 1. This seems pretty easy and whatnot but heres the questions:
(x+3)^2/25 + y^2/12=1

Please help me find the sigma notation for any of the following expressions:
x/(1-x)
2*(cos(x^2))
ln(1-x)
1/(1+x)^2
Thank you!!-Assuming these series are to be centered at x = 0:

How would you find the x and y intercepts in 120 ≤ x + y ≤ 400 for example.-The x intercepts occur when y = 0.
That leaves 120 =
