Answer:

-12w^3 + 30w.

Step-by-step explanation:

–6w(2w^2 - 5) Using the distributive law:

= -6w* 2w^2 - 6w*-5

= -12w^3 + 30w.

taki has her back to a wall. she starts to walk straight forward. she stops and turns 133° to the right and walks back in this d

Nikitich [7]

I'd like to assume that the triangle is a right triangle and you solve for x so...

133 + c = 180 (supplementary property to find one angle of triangle)
c = 47

x = 180 - 90 - 47 (int. angles of triangle = 180)
= 90 - 47
= 43

Therefore, x is 43 degrees

Suppose a tub has the shape of an elliptical paraboloid given by z = ax2+by2 (where a, b are some positive constants). If a marb

Umnica [9.8K]

Answer:

It would roll in this direction.

$\nu = (-a/\sqrt{a^2+b^2},-b/\sqrt{a^2+b^2})$

Step-by-step explanation:

It would roll to the direction of maximum decrease, which is the -1 times the direction of maximum increase, which is given by the gradient of the function.

Since

$z = ax^2 + by^2$

For this case, the gradient of your function would be

$\nabla z = (2ax , 2by)$

And -1 times the gradient of your function would be

$-\nabla z = (-2ax , -2by)\\$

Then, at

$(1,1,a+b),\\x = 1 \\y = 1$

So it would go towards

$v = (-2a,-2b)$

The magnitud of that vector is

$|v| = 2\sqrt{a^2+b^2}$

and to conclude it would roll in this direction.

$\nu = (-a/\sqrt{a^2+b^2},-b/\sqrt{a^2+b^2})$

Find the area of a regular decagon with perimeter 100 units. Show all work.

Slav-nsk [51]

A regular polygon has ten (10) equal sides ( since it is regular).
We are given with the perimeter value which is 100 units and the perimeter formula is P = 10a
Solving for a (the side measurement), we have:
100 = 10a
a= 100/10
a =10

We can now proceed in solving the area and the formula is shown below:
Area = 5/2 a√ (5+2√5)
Area = 5/2 * 10√(5+2√5)
Area = 76.94 square units

The answer is 96.94 square units.
