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:

a)

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.

What is the approximate value of log 12 if log 2 =0.301, log 3 =0.477, and log 6 = 0.778
lara31 [8.8K]

Answer:1.079

Step-by-step explanation:

We know that log a +log b = logab

Using this rule, we will find log12.

Log6 + log2= log12

.778 + .301 = 1.079

Robyn incorrectly solved a rational equation. Her work is shown. What error did she make?
ruslelena [56]

In the second step while distributing she made a mistake

It should have been

2x^2 -4x -6x +18 = 9x - 27

So answer should be

She did not use the distributive property correctly

This isn't something specific I need to know for school, I'm just curious. I know the most commonly used variables are x, y, and
andre [41]

Answer:

Any letter you want

Step-by-step explanation:

The letters used for variables don't matter. What matters is what the variables represent: their numerical value. Variables are just to help identify what needs solving. Other common variables are a, b, and c which are found frequently in trigonometry. To answer your question, there are no "next letters." You can use any letter you'd like as a variable because it holds the same numerical value. Basically, the whole alphabet is at your disposal.

31x + y2 - (xy)2<br> if x = 3 and y = -5
Lerok [7]

Answer:

113

Step-by-step explanation:

To find the result of the equation, you just have to apply the given information that x = 3 and y = -5 into the equation:

31x + y2 - (xy)2

= 31 * 3 + -5 * 2 - (3*-5) * 2

= 93 + -10 + 15 * 2

= 93 -10  + 30

= 83 + 30

= 113

Hope this help you :3
