Answer:
25% = 25/100 = .25
25% of 130 = .25(130) = $32.50
$32.50
if thats what you were saying
Step-by-step explanation:
Answer:
-9ab + 8a + 2
Step-by-step explanation:
Combine like terms and distribute the negative
We are given that x is the arclength from P(1,0) to T(3/4,4/5). In the case of a unit circle, the arclength from P(1,0) to a point T on a unit circle is equal to the radian angle that we rotate from the positive x axis up to T(3/4,4/5). So x is some radian angle. We don't actually have to solve for x, but you can find it using arctan (.8/.75) = 0.8176 radians or about 46°
Then we are told to add π to this x. If you add a rotation of π to a point on a circle, you are rotating that point by 180°. A 180° rotation about the origin is the same as a reflection about the origin. Recall that the transformation for a 180° rotation is (x,y) -> (-x, -y).
Therefore it should be T ' (-3/5, -4/5).
