Find the maximum rate of change of f at the given point and the direction in which it occurs. f(x, y) = 5 sin(xy), (0, 2) maximu

Ahat [919]

Answer with Step-by-step explanation:

We are given that

$f(x,y)=5 sinxy$

Point=(x,y)=(0,2)

We have to find the maximum rate of change of f at given point.

$f_x(x,y)=5ycos(xy)$

$f_x(0,2)=5(2)cos0=10$

$f_y(x,y)=5xcosxy$

$f_y(0,2)=5(0)cos0=0$

$\Delta f(0,2)=f_x(0,2)+f_y(0,2)=10i+0j$

Maximum rate of change of f at point (0,2)= $\mid \Delta f(0,2)\mid=\sqrt{x^2+y^2}$

Where x=Coefficient of i

y=Coefficient of j

By using the formula

Maximum rate of change of f at point (0,2)= $\sqrt{(10)^2+0}=10$

Direction of maximum rate of change of f= $\Delta\har{f}=\frac{\Delta f(0,2)}{\mid\Delta f(0,2)\mid}=\frac{10i}{10}=i$

Cas walks 3/5 miles in 24 min at a steady pace, how long does it take him to walk 2 miles?

san4es73 [151]

Your answer is 80 mins, or an hour and 20 mins. You simply turn that fraction to a decimal by diving 3 with 5. This should turn out to be 0.6. Then you multiply the 24 mins with the 2 miles and it turns out to be 48. After this, you divide 48 by 0.6 and you get 80.

Yo solve....14√x+15 = 71

user100 [1]

Answer:

plug in 16 for x

14√x+15 = 71

14√x+15-15 = 71-15 = 56

14√x/14 = 56/14 = 4

√x^2 = 4^2 = 16
