The answer is 175.45

Surface area of a cone = πrs + πr2
Volume of a cone = 1/3πr2h.
The slant of a right circle cone can be figured out using the Pythagorean Theorem if you have the height and the radius.
Answers for volume problems should always be in cubic units.

Simplify the given expression:. <br> (12/8 t -5)2 =

ch4aika [34]

Answer:

3t-10

Step-by-step explanation:

$( \frac{12t}{8} - 5)2$

$= (\frac{12t}{8} - \frac{5 \times 8}{8} )2$

$= ( \frac{12t - 40}{8} )2$

$= ( \frac{2(12t - 8)}{8} )$

$= 3t - 10$

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.
