6 0

Answer:

Step-by-step explanation:

Solution for cosx=-3/2 equation:

cos((3*pi)/5)*cos((3*pi)/20) = 0

(60*x^3)/(60*x^5) = 0

cos((3*pi)/5)*cos((3*pi)/20) = 0

cos((3*x)/5)*cos((3*x)/20) = 0

1.5/100 = 0

Sonbull [250]

Answer: 13n + 20

Step-by-step explanation:

The cost of each book is $13. That means that if you end up buying "n" books, cost would be:

= Cost of each book * number of books

= 13 * n

= 13n

You would also get charged a flat rate for shipping of $20 which would be added to the above cost to bring a total of:

= 13n + 20

Points A and B lie on a circle with radius 1, and arc AB ⌢ has a length of <img src="https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20%

Murrr4er [49]

Answer:

0.167

EXPLANATION:

To figure out the answer to this question, you'll first need to know the formula for finding the circumference of a circle.

The circumference, C, of a circle is C=2πr, where r is the radius of the circle. For the given circle with a radius of 1, the circumference is C=2(π)(1), or C=2π.

To find what fraction of the circumference the length of AB⌢ is, divide the length of the arc by the circumference, which gives $\frac{\pi }{3}$ ÷ $2\pi$ .

This division can be represented by $\frac{\pi }{3}$ × $\frac{1}{2}$ $\pi =\frac{1}{6}$

can also be rewritten as 0.166 or 0.167.
