Answer: B. same distance

There is the same distance between the point on the preimage to the center of rotation and that of the distance from the corresponding point on the image to the center of rotation. There is change in the distance of the two.

Answer: B. same distance

Explanation:

The rotation consists on the angular motion of the points of the preimage.

Therefore, the center of rotation is fixed and each point is transported a number of degrees (counter-clockwise or clockwise), keeping fixed the distance from the center of rotation.

It is exactly like making a circle but you stop before completing the circle, when you have rotated the amount of degress (angle) desired.

Answer:

95%

Step-by-step explanation:

0.6 of 40 is 24, she bought 24 green balloons.

24 × 1.5 = 36, she bought 36 yellow balloons.

So we have

40 red

24 green

36 yellow

Then from the rest of the information, 2 red, 2 green, and 1 yellow balloon all popped.

We now have

38 red

22 green

35 yellow

for a total of:

95 balloons out of 100 original balloons, 95%

Two real solutions of tx^2+3x_7=0
Olegator [25]

The number of solutions of a quadratic equation

ax^2+bx+c=0

Depends on its discriminant

/Delta=b^2-4ac

If /Delta>0 there are two distinct solutions

If /Delta=0 there are two coincident solutions

If /Delta<0 there are no solutions.

We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:
