An 80° angle should be used to shoot the weapon. If you want to precise then it would be an 80.5376° angle. Hope this helps!
Answer: x=6
Step-by-step explanation:
3(x-2)=12
3x-6=12
3x=18
x=6
The answer would be B, because in order for the function to have two values of x where the function value is the same, it must have a point in the function where it is a max or min. Because it has a max or min, at that point, the slope of the function is 0, meaning that B is the correct answer because B states that at that point that is a max or min, the slope of the function is 0.
We first complete the square.
y=-x^2+2x+1
y=-x^2+2x-1+1+1
y=-(x-1)^2+2
The maximum point is (1,2) since -1 in ( ) meant 1 unit to the right and +2 meant 2 units up.
The maximum point is (1,2) but the maximum value means the y value which is simply just 2.
Done!
