I think task 1 is B
Hope this helps
Don't forget to rate and thanks me
No (3,4) is not a solution to y=4x - 9 this is because if you place those co-ordinates in the equation it will be formed as this
4 = 4x3 -9
4x3 = 12
12- 9 = 3. not 4
therefore if you switch the co-ordiantes and do (4,3) instead of (3,4)
59.346
V = pi * r^2 * h
V = 3.14 * 3^2 * 2.1
V = 3.14 * 9 *2.1
V = 3.14 * 18.9
V = 59.346
The answer is 20 degrees
(We know that the angle is 40 because opposite angles are the same)
I hope this helps! :)
