Find the exact value of each trigonometric function for the given angle θ.

irina [24]

Answer:

[rad] 2.41

Step-by-step explanation:

Since it gave you the point and the angle to find, you simply just have to solve for the inverse of cot. Remember cot is the opposite of tan, so cot is cos/sin. In that case, we plug into the calc (in radians):

cot^-1(-√5/2)

And we should get 2.41 as our answer!

Combine the following expressions:

melisa1 [442]

ANSWER

$(4n - 1)\sqrt{3 n} + 3\sqrt{n}$

EXPLANATION

The given expression is

$\sqrt{48 {n}^{3} } + \sqrt{9n} - \sqrt{3n}$

We remove the perfect squares under the radical sign.

$\sqrt{16 {n}^{2} \times3 n} + \sqrt{9n} - \sqrt{3n}$

We can now take square root of the perfect squares and simplify them further.

$\sqrt{16 {n}^{2}} \times \sqrt{3 n} + \sqrt{9} \times \sqrt{n} - \sqrt{3n}$

This simplifies to:

$4n\sqrt{3 n} + 3\sqrt{n} - \sqrt{3n}$

This further simplifies to:

$(4n - 1)\sqrt{3 n} + 3\sqrt{n}$

Pedro has 3 boxes of 6 markers. Rafael has 5 boxes of 5 markers. One of the friends arranges all his markers into 2 equal groups

Komok [63]

Answer:

see below

Step-by-step explanation:

Pedro has 3 boxes of 6 markers.

3*6 = 18 markers

We can divide this by 2 because this is even

18/2 = 9

There are 9 in each group

Rafael has 5 boxes of 5 markers

5*5 = 25

We cannot divide this by 2 because this is odd
