A.
-5 is less than 0 so it should be A.
7 and 8 the slope is what is multiplied by x. 9 make y by itself which gives y=3/4x-2. 3/4 is the slope because its multiplied by x. 10 make x by itself to get the x intercept. first subtract 4x. y-4x=-2. then subtract y by both sides.-4x=-2-y. then divide by NEGATIVE 4. after that you will get x intercept form
Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2
<h3>
Answer: choice B) counterclockwise rotation of 90 degrees around the origin</h3>
To go from figure Q to figure Q', we rotate one of two ways
* 270 degrees clockwise
* 90 degrees counterclockwise
Since "270 clockwise" isn't listed, this means "90 counterclockwise" is the only possibility.
It would remain the same (4/5). <span>Sin of the angle is unchanged regardless of the size; it is a ratio related only to the angle, not the size of the triangles.</span>
