Answer:
x cannot be -4,-3, or 13
x can be anything else
Step-by-step explanation:
There are infinitely many values x can take where the relation above will be a function.
For it to be a function, you just need to make sure each x is only assigned one y value.
So x couldn't be -4 because it would by assigned to y=2 and y=0.
x couldn't be -3 because it would be assigned to y=1 and y=0.
x couldn't be 13 because it would be assigned to y=5 and y=0.
So as long as x is not chosen to be -4,-3, or 13 your relation here is a function.
Angle 2 = 120° (C)
Both angle 2 and angle 8 should add up to 180°. If you subtract 60° from 180°, you would have 120°.
I would approach this question by changing the equations from polar to cartesian form. Do you know how to do that?
0.224 is the answer to this question.
Answer:
Step-by-step explanation:
First, you would have to make it so that T is on one side and everything else is on the other. You would end up with this:
T=1.04+5.60
Solve. You should get to this:
T=6.64
