Answer:
Step-by-step explanation:
The equation of the form

has radius r.
Now your equation is

Hence its radius is 
3 1/8 is the answer because 5x5=25 divided by 3 and you get roughly 24 with one left over so you put the one left over in a fraction hence 1/8.
have a nice day!
Answer: 2598.8
Solution:
Step one: 49•12.80 = 627.2 (the amount that people under 16 payed)
Step two: 155-49=106 (the amount of people over 16)
Step three: 106•18.60=1971.6 (the amount of money that people over 16 payed)
Step four: 627.2+1971.6=2598.8 (the total amount of collected money from tickets)
Step-by-step explanation:
1/(1 - p + p²) - 1/(1 + p + p²) - 2p/(1 - p² + p⁴) =
[ (1 + p + p²)-(1 - p + p²)/(1 - p + p²)(1 + p + p²) ] - 2p/(1 - p² + p⁴) =
2p/(1 + p + p² - p - p² - p³ + p² + p³ + p⁴) - 2p/(1 - p² + p⁴) =
2p/(1 + p² + p⁴) - 2p/(1 - p² + p⁴) =
[ 2p(1 - p² + p⁴) - 2p( 1 + p² + p⁴) ]/(1 + p² + p⁴)(1 - p² + p⁴) =
(2p - 2p³ + 2p⁵ - 2p - 2p³- 2p⁵) / (1 - p² + p⁴ + p² - p⁴ + p⁶ + p⁴ - p⁶ + p⁸) =
-4p³ / (1 + p⁴ + p⁸)
