Urgent help needed plz.

There are 6 letters in the word "autumn" so
6! = 6*5*4*3*2*1 = 720
represents the number of ways to arrange the letters (order matters)

Note how there are two letter "u"s here which can't be told apart. If we could tell them apart, then the answer would be 720. However, we can't tell them apart. So we're doubly counting things. To undo this, we divide by 2

720/2 = 360

------------------------------------------------

Final Answer: 360

Which angle has a tangent and cosine that are both negative? a. 110° b. 180° c. 210° d. 340°

Veronika [31]

<h3>110 degrees has tangent and cosine that are both negative</h3>

Solution:

We have to find the angle that has a tangent and cosine that are both negative

Option A)

$110^{\circ}$

$tan\ 110^{\circ} = -2.7474^{\circ}$

$cos\ 110^{\circ} = -0.3420^{\circ}$

Thus 110 degrees has tangent and cosine that are both negative

Option B)

$180^{\circ}\\tan\ 180^{\circ} = 0\\\\cos\ 180^{\circ} = -1$

Thus, 180 degrees does not have tangent and cosine that are both negative

Option C)

$210^{\circ}\\\\tan\ 210^{\circ}=0.5773^{\circ}\\\\\cos\ 210^{\circ} = -0.8660^{\circ}$

Thus, 210 degrees does not have tangent and cosine that are both negative

Option D)

$340^{\circ}\\\\tan\ 340^{\circ} = -0.3639\\\\cos\ 340^{\circ} = 0.9396$

Thus, 340 degrees does not have tangent and cosine that are both negative

An expression that uses variables to state a rule is a ______

nikdorinn [45]

Formula

An expression that uses variables to state a rule is a formula

<h2>Explanation:</h2>

An expression that uses variables to state a rule is a formula. It's important to know that formulas uses the equals sign (=) and includes two or more variables. Formulas gives us information that we express symbolically. For example, the well known formula for the volume of a sphere is defined as:

$V=\frac{4}{3} \pi r^3 \\ \\ \\ Where: \\ \\ V:Volume \ of \ the \ sphere \\ \\ r:Radius \ of \ the \ sphere$

So in this formula we have a relationship between the volume of a sphere and its radius, so if we have information about the radius of it we can easily calculate the volume of it.
