<h3>Answer: Choice C</h3>

===========================================

Explanation:

Point P is the center of dilation. So it does not move for any dilation applied as long as its stays as the center of course.

The scale factor 4/3 = 1.33 approx means that point A's distance from P will be scaled 1.33 times larger. In other words

(A'P)/(AP) = 4/3 = 1.33

Points B' and C' are also further away than their counterparts, with relation to the center point P.

All of this means the image triangle A'B'C' is larger compared to its preimage triangle ABC.

What results is what you see in diagram C

-------------------

Side notes:

  • Diagram A is not correct because point B hasn't moved when it should have.
  • Diagram B is not correct because the image triangle is smaller when it should be larger compared to its preimage
  • Diagram D is not correct because B hasn't moved

ioda

Answer:

Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%.

Step-by-step explanation:

Given that Elena receives $ 131 per year in simple interest from three investments totaling $ 3000, and part is invested at 3%, part at 4% and part at 5%, and there is $ 1000 more invested at 5% than at 4%, to find the amount invested at each rate, the following calculations must be performed:

1500 x 0.05 + 500 x 0.04 + 1000 x 0.03 = 75 + 20 + 30 = 125

1600 x 0.05 + 600 x 0.04 + 800 x 0.03 = 80 + 24 + 24 = 128

1700 x 0.05 + 700 x 0.04 + 600 x 0.03 = 85 + 28 + 18 = 131

Therefore, Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%

astronomers measure large distances in light years one light year is the distance that light can travel in one year or approxima
sveticcg [70]
What you can do in this case is the following rule of three to find the result:
 1 light year ---> 5.88 * 10 ^ 12 miles
 3.2 * 10 ^ 2 light year ---> x
 Clearing x we have:
 x = ((3.2 * 10 ^ 2) / (1)) * (5.88 * 10 ^ 12)
 x = 1.88 * 10 ^ 15 miles
 answer:
 In scientific notation, approximately it is 1.88 * 10 ^ 15 miles
