A shelf holds 12 books in a row. How many ways are there to choose five books so that no two adjacent books are chosen

Mathematics

Answer:

<u>792 ways</u>

Step-by-step explanation:

We can solve this using the combination formular

nCr= \frac{n!}{r!(n-r)!} where n represents the total number of objects/items, and r represents the number of items being chosen at a time.

Hence, in this case, n =  12, r = 5, which is = nCr= \frac{12!}{5!(12-5)!} = 792.

Therefore, there are 792 ways to choose five books so that no two adjacent books are chosen.

The functions f (theta) and g (theta) are sine functions, where f (0) equals g (0) equals 0.The amplitude of f (theta) is twice
777dan777 [17]
If period of f(\theta) is one-half the period of g(\theta) and
<span>g(\theta)  has a period of 2π, then T_{g} =2T_{f}=2 \pi and T_{f}= \pi.
</span>
To find the period of sine function f(\theta)=asin(b\theta+c) we use the rule T_{f}= \frac{2\pi}{b}.
<span /><span />
f is sine function where f (0)=0, then c=0; with period \pi, then f(\theta)=asin 2\theta, because T_{f}= \frac{2 \pi }{2} = \pi. 

To find a we consider the condition f( \frac{ \pi }{4} )=4, from where asin2* \frac{\pi}{4} =a*sin \frac{ \pi }{2} =a=4.

If the amplitude of f(\theta) is twice the amplitude of g(\theta) , then g(\theta) has a product factor twice smaller than f(\theta) and while period of g(\theta)<span> </span> is 2π and g(0)=0, we can write g(\theta)=2sin\theta.

Find the value of x needed to make the equation true.<br> 8x – 4 = 13x + 6
Kipish [7]

Answer:

x = -2

Step-by-step explanation:

<u><em>First, you need to subtract 8x from both sides:</em></u>

8x – 4 = 13x + 6

-8x         -8x

____________

-4 = 5x + 6

<em><u>Then, subtract 6 from both sides:</u></em>

-4 = 5x + 6

-6         - 6

________

-10 = 5x

<u><em>Lastly, divide both sides by 5:</em></u>

-10 = 5x

-2 = x
