Find an equation of the plane tangent to the following surface at the given point.z equals tangent Superscript negative 1 Baseli

Sergeeva-Olga [200]

Let f(x, y, z) = z - arctan(x y). Compute the gradient of f at the point (0, 3, 0):

∇ f(x, y, z) = (-y / (1 + x²y²), -x / (1 + x²y²), 1)

∇ f (0, 3, 0) = (-3, 0, 1)

This vector is orthogonal to the surface z = f(x, y). Then the equation of the tangent plane is

∇ f (0, 3, 0) • (x, y - 3, z) = 0

(-3, 0, 1) • (x, y - 3, z) = 0

-3x + z = 0

z = 3x

Answer:

See Below

Step-by-step explanation:

There are two runners that run at different average speeds, let these be Ra (runner a) and Rb (runner b). We also have two differnt distances that can be ran, let Leg A La and Leg b Lb. We get the equation bellow:

$Total time = L_a/R_1 + L_b/R_2$

Mickey = 35km/h

Minnie = 25km/h

Leg A = 30

Leg B = 20

Since Mickey is the fastes, he should run the section with the longest distance:

$Total time = L_a/R_1 + L_b/R_2\\Total time = 30_k_m/35_k_m_/_h + 20_k_m/25_k_m_/_h\\Total time = (30/35)_h + (28/35)_h\\Total time = (58/35)_h$
