Answer:

x ≈ 39.2°

Step-by-step explanation:

Given

324 = 1409 - 1400 cos x ( subtract 1409 from both sides )

-1085 = - 1400 cos x ( divide both sides by - 1400 )

0.775  = cos x, thus

x = cos^{-1} (0.775) ≈ 39.2° ( to 1 dec. place )

Find the partial derivatives of the function w=4r2+6s2+
lyudmila [28]
I'm taking the liberty of editing your function as follows:  <span>w=4r^2+6s^2, where I use " ^ " to indicate exponentiation.

The partial of w with respect to r is 8r.  That with respect to s is 12s.</span>
