Given:
There are given that the zeroes and degrees of the polynomial:
Explanation:
From the concept of a polynomial:
A polynomial has a as zero if and only if (x -a) is a factor of the polynomial.
Then,
From the given polynomial:
Then,
Final answer:
Hence, the polynomial is shown below:
Answer:
18
Step-by-step explanation:
3+9=12
12/2=6
6x3=18
BTS is sooooo trash .....
Cos(17pi/8)
cos(17π/8)
But π radians = 180°
17π/8 radians = (17/8) * 180 = 382.5
But this is more than 360°, so we have the basic angle by subtracting 360°
382.5 - 360 = 22.5
cos(17π/8) = Cos22.5
Recall double angle formula for cos.
cos2θ = 2cos²θ - 1
Therefore
cos(2*22.5) = 2cos²(22.5) - 1
cos45 = 2cos²(22.5) - 1
(√2)/2 = 2cos²(22.5) - 1
2cos²(22.5) - 1 = (√2)/2
2cos²(22.5) = (√2)/2 + 1
2cos²(22.5) = (2 + √2) / 2
cos²(22.5) = (2 + √2) / 4
cos22.5 = √( (2 + √2)/4) ................(note)
cos22.5 = √(2 + √2) / 2
Option (a) seems like the closest, comparing to (note) above.
Answer:
Okay lets start with the easy part's so we know that it is certain to scorer more then 0 and its likely scoring 30 points and same for 50 points or less and its very unlikey to score more then 100 points
I'm pretty sure thats right
