Find the linearization of the function f(x, y)=√(129−3x^2−2y^2) at the point (5, -5). L(x, y)= ?

Use the linear approximation to estimate the value of f(4.9,−4.9) = ?

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 33 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30 ∘c on monday, but decreased at a constant rate in the next 33 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.
