A scientist needs to make 2 liters of saline solution (salt water), in which the salt level must be at 15% concentration (meaning 15% of the water is salt). Unfortunately, the scientist only has two types of saline solution in his possession. He has saline solution with a 10% concentration level and saline solution with a 35% concentration level. How much of each type of saline solution should the scientist mix together to achieve 2 liters of saline solution at a concentration level of 15%?

Let xx represent the amount 10% saline solution and let yy represent the amount of 35% saline solution.

To find the extreme values of a function f(x. y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x, y)=xy

This figure consists of a rectangle and semicircle. what is the perimeter of this figure use 3.14 for pi 60.84m 72.84m 79.68m 98.52m

Aline passes through the point (–7, 5) and has a slope of 1/2 which is another point that the line passes through?
