Yes because the y intercept would be a different value for the new equation unless it is zero

Suppose that P is the point on the unit circle obtained by rotating the initial ray counterclockwise through 330 degrees. Find t

Flauer [41]

Answer:

Reference angle will be 30°

sin(330°) will be equal to $\frac{-1}{2}$

cos(330°) will be equal to 0.866

Step-by-step explanation:

We have given angle is 330°

As the angle $330^{\circ}$ is in forth quadrant

We know that in forth quadrant the reference angle is given by

Reference angle $=360-angle$

As the angle is 330°

So the reference angle will be $=360-330=30^{\circ}$

Now we have to find the value of

sin(330°) $=sin(2\pi -30)=-sin(30)=\frac{-1}{2}$

And now $cos(330^{\circ})=cos(2\pi -30)=cos30=0.866$

I need help on 11 plz I need a slot of help

Galina-37 [17]

mean = (sum of values) / (number of values)

we know mean is 13 and we are given 8 values. The ninth value is the missing x:

13 = ((sum of 8 values) + x)/9

13 = (12+10+15+12+13+15+11+15+x)/9

13*9 = 103+x

x = 14

The missing value is 14. There are 14 pillows in the last box.
