The sum of 2 nonnegative numbers is 20. Find the numbers if:
a)if the product of one number and the square root of the other is to be as large as possible, and
b)if one number plus the square root of the other is to be as large as possible.

The sum of 2 nonnegative numbers is 20. Find the numbers if:
a)if the product of one number and the square root of the other is to be as large as possible, and
b)if one number plus the square root of the other is to be as large as possible.

Note * denotes multiplication
Let one number be x; therefore the other number is (20-x) as the sum of the two nonnegative numbers is 20

I have this differential equation.
y' = x^2*cos^2(y).
I don't know if it's a separable differential equation or a first order differential equation. Please show me the steps in how to solve it.
Thank you.

If you were to transform this PDE with the substitution S = Ke^x, where x is a variable and K a constant, what would be the resulting equation?

1. Rotate the coordinate axes x and y by the appropriate acute angle theta, so as to eliminate the cross product term (xy) from the equation x^2 + xy + y^2 - 6 = 0. State the value of theta, give the transformed equation in terms of the new rotated coordinates u and v, and identify the figure it represents.
2. Find cartesian

The techniques for solving linear equations and linear inequalities are similar, yet different. Explain and give an example of both a linear equation and a linear inequality that demonstrates this difference.

2. If x=1 and x=-8, then form a quadratic equation.
3. What type of solution do

Can I get some help for me to understand what is the difference between an equation and an expression? Can you solve for a variable in an expression? Could you explain. Can you solve for a variable in an equation? Can you explain this to me. Could you give me a phrase or sentence for me to understand?
