Rectangle A′B′C′D′ is the image of rectangle ABCD after a dilation.

The scale factor of the dilation from ABCD to A′B′C′D′ is 3.

Explanation:

  • In the smaller rectangle, ABCD the length of the rectangle is 4 - 1 = 3 units, while the width of the rectangle is 5 - 1 = 4 units. For the larger rectangle, A′B′C′D′ the rectangle's length is 12 - 3 = 9 units and the rectangle's width is 15 - 3 = 12 units.
  • To determine the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it can either be the rectangle's length or width.                                                                    So the scale factor = \frac{lengthafterdilation}{lengthbeforedilation}  = \frac{9}{3} = 3.                                                             While the scale factor for width = \frac{widthafterdilation}{widthbeforedilation} = \frac{12}{4} = 3.
  • So the rectangle ABCD is dilated by a scale factor of 3 to produce rectangle A′B′C′D′.

Evaluate the limit. lim n > [infinity] 9n^3 +5n - 2n/ 2n^3
expeople1 [14]

Answer:

The value of the limit is \frac{9}{2}

Step-by-step explanation:

When we are working with limits in which the variable goes to infinity, we only take the highest order factor of the numerator and of the denominator.

So we have

$\lim_{t \to +\infty} \frac{9n^{3}}{2n^{3}}$

We can simplify the cubes.

$\lim_{t \to +\infty} \frac{9}{2}$

The limit of a constant is the proper constant.

So the value of the limit is \frac{9}{2}

Find the length of the missing side. Give your answer in the simplest radical form.
taurus [48]

Answer:

x = 2\sqrt{5}

Step-by-step explanation:

Use Pythagorean theorem,

Hypotenuse² = base² + altitude²

x² = (√8)² + 4²

  =  8 + 16

  = 20

x = √20 = \sqrt{2*2*5} = 2\sqrt{5}

x = 2\sqrt{5}
