Suppose you are climbing a hill whose shape is given by the equation z = 1300 − 0.005x2 − 0.01y2, where x, y, and z are measured

Lisa [10]

Answer:

a) "ascend"

Step-by-step explanation:

The equation is $z = 1300-0.005x^2-0.01y^2$

This question is asking for the value of the directional derivative in the direction of -j [since south that's y negative]

So, this is the negative of partial derivative of y. Thus we have:

$z = 1300-0.005x^2-0.01y^2\\z_y=-0.02y$

Now we are at (100,120,1106), we take y value of 120 and put it in the partial:

$z_y=-0.02y\\z_y=-0.02(120)\\z_y=-2.4$

We take the negative, that is -(-2.4) = 2.4

Since this is positive, we can say the hill is sloping upward at this point, so you will start to ascend.

If z varies directly with the product of x and y(z=k x y) , then z is said to vary jointly with x and y .

Dafna1 [17]

The value of z varies jointly with w and y.

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of constant of variation

let k be the constant of proportion

When a quantity varies directly with others, then we have a relation, y = kx

Given relation is z = kxy —-- 1

Also x varies directly with w i.e. x = k'w, where k' is constant of variation for x and w

Using in equation 1, we have,

z = k(k'w)y

z = kk'wy

z = Kwy, where K is constant of variation i.e. K = kk'

It shows that z varies directly with w and y.

Hence, z varies jointly with w and y.
