Write an equation of the ellipse with focus at (0,+-9) and vertices at (0,+-13)
The major axis is along the y-axis
We need to find " b" = √[a^2 − c^2] = √ [ 13^2 − 9^2] = √ [169 − 81] = √88
So.... the equation is
y^2 / a^2 + x^2 / b^2 = 1
y^2 / 169 + x^2 / 88 = 1

Step-by-step explanation:
\boldsymbol{\mathbf{4 ounces water we need to add.}}
An after shave lotion contains 45% of ethyl alcohol
i.e 100% - 45% = 65% nonalcoholic
As mentioned, we have 8 ounces of fluid and that contains 45% of ethyl alcohol.
i.e
We need fluid which 70% nonalcoholic.
i.e 100 - 70 = 30% of alcohol.
Then there is already 3.6 ounces of alcohol in fluid.
As required, Let consider 3.6 ounce is 30% of alcohol.
70% must be other liquid.
That is equal to =
=
= 8.4 Ounces Of other liquid.
Then total ounces of the lotion is
= 3.6 + 8.4
= 12 ounces.
Water required to add is,
= 12 - 8
=
