Find the slope of the line using the two points by plugging them into this formula: m = y2 - y1 / x2 - x1 where the two points are x1, y1 and x2, y2 and m is the slope.
Given:
There are given that the cos function:
Explanation:
To find the value, first, we need to use the half-angle formula:
So,
From the half-angle formula:
Then,
Since 105 degrees is the 2nd quadrant so cosine is negative
Then,
By the formula:
Then,
Put the value of cos210 degrees into the above function:
So,
Final answer:
Hence, the value of the cos(105) is shown below:
Answer:
go to the skating rink
Step-by-step explanation:
if multiply 5x 7 you get 35
If you add 35+15 you get 50 which is the amount of money you have. So if you chose the bowling ally you could bring 7 friends
but is you multiply 3x10 that equals 30
Add that by 20 and you get 50
let me know if its right
Answer:
No solution.
Explanation:
The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace f(x) with 0 and solve for x.
