5. The two figures are scaled copies of each other.

The quadrilaterals are similar and are related by a scale factor, taken from

a specific location, that maps the points on one figure to the other.

a. The scale factor that takes Figure 1 to Figure 2, is 3

b. The scale factor that takes Figure 2 to Figure 1 is \dfrac{1}{3}

Reasons:

From the question, we have that Figure 1 is a scaled copy of Figure 2, therefore;

Let ABCD represent Figure 1, we have;

ABCD ~ PQRS

Length of \overline{AD} = √(2² + 3²) = √(13)

Length of \overline{PS} = √(6² + 9²) = √(117) = √(9 × 13) = 3·√(13)

Therefore;

a. The scale factor that takes Figure 1 to Figure 2, SF₁₂, is therefore;

SF_{12} =  \mathbf{\dfrac{\overline{PS}}{\overline{AD}}}

Which gives;

SF_{12} = \dfrac{3 \cdot \sqrt{13} }{\sqrt{13} } = 3

The scale factor that takes Figure 1 to Figure 2, SF₁₂ = <u>3</u>

(<em>3 times the lengths of Figure 1 gives the lengths on Figure 2</em>)

b. The scale factor that takes Figure 2 to Figure 1, SF₂₁, is given as follows;

SF_{21} = \mathbf{\dfrac{\overline{AD}}{\overline{PS}}}

Which give;

SF_{21} = \dfrac{\sqrt{13} }{3 \cdot \sqrt{13} } =  \mathbf{\dfrac{1}{3}}

The scale factor that takes Figure 2 to Figure 1, SF₂₁ is \underline{\dfrac{1}{3}}

If I deposit $100,000 in a retirement account that gives 8 % paid annually, what will be balance after 25 years?
Zinaida [17]

Answer:

$300,000

Step-by-step explanation:

To find 8% of 100,000 all you need to do is multiply 100,000 by .08.

100,000 (.08) = 8,000

The 8,000 accounts for one year, so now you have to multiply 8,000 by 25.

8,000 (25) = 200,000

Now add the initial amount to the additional 200,00 that will be paid to the retirement account.

100,000 + 200,000 = 300,000

The answer is $300,000.
