Hello!

You can solve this algebraically

7w < -42

Divide both sides by 7

w < -6

The answer is any number less than -6 or w < -6

Hope this helps!

Answer: -16/65

Step-by-step explanation:

Drawing the right triangle (as attached) gives us that \arctan \left(\frac{12}{5} \right)=\arcsin \left(\frac{12}{13} \right)

Also, -\arcsin \left(-\frac{3}{5} \right)=\arcsin \left(\frac{3}{5} \right)

This means our original expression is equal to:

\cos \left[\arcsin \left(\frac{12}{13} \right)+\arcsin \left(\frac{3}{5} \right) \right]

Using the cosine addition formula, which states \cos(a+b)=\cos a \cos b-\sin a \sin b, we get this itself is equal to:

\cos \left(\arcsin \left(\frac{12}{13} \right) \right)\cos \left(\arcsin \left(\frac{3}{5} \right)\right)-\sin \left(\arcsin \left(\frac{12}{13} \right) \right)\sin \left(\arcsin \left(\frac{3}{5} \right)\right)

Since \sin^{2} \theta+\cos^{2} \theta=1, we know that:

\sin^{2} \left(\arcsin \left(\frac{12}{13} \right)\right)+\cos^{2} \left(\arcsin \left(\frac{12}{13} \right)\right)=1\\\\\frac{144}{169} +\cos^{2} \left(\arcsin \left(\frac{12}{13} \right)\right)=1\\\\cos^{2} \left(\arcsin \left(\frac{12}{13} \right)\right)=\frac{25}{169}\\\\cos \left(\arcsin \left(\frac{12}{13} \right)\right)=\frac{5}{13}

Similarly, cos(arcsin(3/5))=4/5.

This means the given expression is equal to:

\left(\frac{5}{13} \right) \left(\frac{4}{5} \right)-\left(\frac{12}{13} \right) \left(\frac{3}{5} \right)\\\\\frac{20}{65}-\frac{36}{65}=\boxed{-\frac{16}{65}}

What kind of sequence is this?<br> 36, 144, 432, -864, ..
jenyasd209 [6]

Answer:

<h3> A Geometric sequence with common ratio 3</h3>

Step-by-step explanation:

A sequence of number is called Geometric sequence if the first number is being multiplied with a constant to get the rest of the numbers

ratio between 2 adjacent numbers in a sequence will be a constant and is called common ratio.

in the given sequence the ratio between any pair of adjacent numbers is 3.

∵ this is a geometric sequence with common ratio 3

Hello!

A heptagon has 7 sides

You divide the perimeter by the amount of sides

560 / 7 = 80

Each side is 80 centimeters

The answer is 80cm
