36.9
Step-by-step explanation:
Answer:
,
Step-by-step explanation:
Note I'm using a, instead of theta to represent angles.
To convert rectangular to polar, apply these formulas
Note : Rectangular coordinates are the coordinates you were learning since elementary school or middle school.
The first number is x, and the second is y.
So
Since our y coordinate is negative and x coordinate is Positve , on the unit circle, the angle must be in the fourth quadrant.
So the angle must be in between
So our answer is
(6, 11pi/6).
Because it gives you a number that is close to the answer and if it is close to your number like for instance, the actual answer is 10 then if you get 5 as your estimate that's close.
F(x)=x²+2x-1 and g(x)=2x-4 <span>2f(x)-3g(x)=?
</span>2f(x)=2*(x²+2x-1)=2x²+4x-2
3g(x)=3(2x-4)=6x-12
2f(x)-3g(x)=(2x²+4x-2) - (6x-12)= 2x²+4x-2 - 6x+12 =2x²-2x +10
<em>2f(x)-3g(x) = 2x²-2x +10</em>
