The surface of a mountain is modeled by the equation h(x, y) = 5000 - 0.001x² - 0.004y². A mountain climber is at the point (500, 300, 4390). In what direction should the climber move in order to ascend at the greatest rate?

Answers

Answer:

i-2.4j

Step-by-step explanation:

Given that,

The surface of a mountain is modeled by the equation as follows :

h(x,y)=5000 -0.001x^2-0.004y^2

A mountain climber is at the point (500, 300, 4390).

We need to find the direction in which he should move in order to ascend at the greatest rate.

To find direction, first finding the gradient of h as follows :

\nabla h(x,y)=-0.002xi-0.008yj

Now put x = 500 and y = 300

So,

\nabla h(x,y)=-0.002(500)i-0.008(300)j\n\n\nabla h(x,y)=i-2.4j

The direction of the climber is i-2.4j

This is so easy but i can find this in the internet but what i wanna know is what goes in the Missing blank 50 take away ? equals 20

Answers

50 minus 30 is 20.
You could subtract 20 from 50 to see what you would get, and then just plug it in to double check.
