Answer:
18z 2+17z+4
Step-by-step explanation:
it hard try to give more point
The basic angle for 1/2 is 60°, and cosines are negative in the first and third quadrant.
So, you take 180° - 60° = 120° to get the angle in the first quadrant, and 180° + 60° = 240° to get the angle in the third quadrant.
Since only 120° is an option, the answer is
B.

Answer:
A. b2 – 4ac = 0
Step-by-step explanation:
Hey user☺☺
Option a is correct
Because the graph has only one solution.
As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.
Hope this will help☺☺
Answer:
7 1/17 shifts
Step-by-step explanation:
That would be 7 1/2 divided by 1 1/16
= 15/2 / 17/16
= 15/2 * 16/17
= 15 * 8 / 17
= 120/17
= 7 1/17 shifts
