Question:

Find the scale factor of trapezoid [tex]\mathrm{Q}\mathrm{R}\mathrm{S}\mathrm{T}[/tex] if it is dilated to [tex]\mathrm{Q}^{'} \mathrm{R}^{'} \mathrm{S}^{'} \mathrm{T}^{'}[/tex].

Type your result in the empty box provided below.

Answer:

The scale factor is 2

Step-by-step explanation:

Given

See attachment for plots

Required

Determine the scale factor

Using QR and Q'R' as points of reference.

From the attached plot, we have:

[tex]QR = 4\ units[/tex]

[tex]Q'R' = 8\ units[/tex]

The scale factor (k) from [tex]\mathrm{Q}\mathrm{R}\mathrm{S}\mathrm{T}[/tex] to [tex]\mathrm{Q}^{'} \mathrm{R}^{'} \mathrm{S}^{'} \mathrm{T}^{'}[/tex]. is:

[tex]k = \frac{Q'R'}{QR}[/tex]

[tex]k = \frac{8\ units}{4\ units}[/tex]

[tex]k =2[/tex]

A coat has an original price of $48.99. Gloria wants to calculate the final cost of the coat including the 7% sales tax. She could use the expression 0.07 (48.99) + 48.99 to determine the final cost. Which other express could she also use to determine the final cost?

(0.07) ($48.99)
(1.07) ($48.99)
(1.93) ($48.99)
(0.93) ($48.99)

Answers

Answer (1.07)(48.99)
Ex
Since the first expression was
(0.07 x 48.99) + 48.99
Then multiply 0.07 by 48.99 =3.4293 + 48.99 = 52.4193

Try

1.(0.07)(48.99) =3.4293

2.(1.07)(48.99)=52.4193

3.(1.93)(48.99)= 94.5507

4.(0.93)(48.99)= 45.5607


The equation 2 was the only one that had the Sam answer as 52.4193

The 5th term in a geometric sequence is 120. The 7th term is 30. What are the possible values of the 6th term of the sequence.

Answers

Answer:

± 60

Step-by-step explanation:

aₙ = a₁ * rⁿ⁻¹

a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶     (1)

a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴     (2)

(1)/(2): 30/120 = 1/4 = r²

r = ± 1/2   or ± 0.5

a₁ = a₇/r⁶ = 30/0.5⁶ = 1920

a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60

The possible values of the 6th term of the sequence ± 60.

The 5th term in a geometric sequence is 120.

The 7th term is 30

We have to determine the 6th term of the sequence.

What is the formula for the nth term of the sequence?

[tex]a_n = a* r^n[/tex]

a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶  ......   (1)

a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴   ...  (2)

(1)/(2): 30/120 = 1/4 = r²

r = ± 1/2   or ± 0.5

a₁ = a₇/r⁶ = 30/0.5⁶ = 1920

a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60.
