The length of CD is 12 units C’D’ is the image of CD under a dilation with a scale factor of n.Which of these are true?

Korvikt [17]

Answer: FIrst option, Fourth option and Fifth option.

Step-by-step explanation:

First it is important to know the definition of "Dilation".

A Dilation is defined as a transformation in which the Image (which is the figure obtained after the transformation) and the Pre-Image (this is the original figure, before the transformations) have the same shape, but their sizes are different.

If the length of CD is dilated with a scale factor of "n" and it is centered at the origin, the length C'D' will be:

$C'D'=nCD=(n)(12\ units)$

Therefore, knowing this, you can determine that:

1. If $n=\frac{3}{2}$ , you get:

$C'D'=(\frac{3}{2})(12\ units)=18\ units$

2. If $n=4$ , then the length of C'D' is:

$C'D'=(4)(12\ units)=48\ units$

3. If $n=8$ , then:

$C'D'=(8)(12\ units)=96\ units$

4. If $n=2$ , then, you get that the lenght of C'D' is:

$C'D'=(2)(12\ units)=24\ units$

5. If $n=\frac{3}{4}$ , the length of C'D' is the following:

$C'D'=(\frac{3}{4})(12\ units)=9\ units$

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r

NISA [10]

The exponential function y = 290 · 0.31ˣ reports a decay as its growth rate is less than 1 and greater than 0. Its percentage rate of decrease is equal to 69 %.

<h3>How to determine the behavior of an exponential function</h3>

Exponential functions are trascendental functions, these are, functions that cannot be described algebraically. The simplest form of exponential functions is shown below:

y = a · bˣ (1)

Where:

a - Initial value
b - Growth rate
x - Independent variable.
y - Dependent variable.

Please notice that this kind of exponential function reports a growth for b > 1 and decay for b < 1 and b > 0. According to the statement we have the function y = 290 · 0.31ˣ, then we conclude that the exponential function given reports a decay.

The percentage rate of decrease is determined by the following formula:

100 × (1-0.31) = 100 × 0.69 = 69 %

The percentage rate of decrease related to the exponential function is 69 %.
