1. 0.5x+3.5
Slope: 0.5
y-intercept: (0,3.5)
x: (-7,0)
y: (0,3.5)
Answer:
It is true, because the cosine function has a period of 2π
Step-by-step explanation:
Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:
Taking as , is equal to
The equation is true!
<u>Note:</u> The cos function is even function
Hence, the equation is true, because the cosine function has a period of 2π, NOT because the cosine function is ODD, which it is not!!
Answer:
5 seats
Step-by-step explanation:
if I'm getting the right idea, the seats are NOT enough
since the number of arrangement of 10 people in a row is
10! = 3628800 which is a lot larger than 30240.
---------------------------------------------------------------------------------------
Let number of seats be
10PX = 30240
= 30240
(10-X)! =
(10-X)! = 120
(10-X)! = 5!
10-X = 5
X = 5
