Answer: $\bold{a_n=120\bigg(\dfrac{1}{3}\bigg)^{n-1}}$

<u>Step-by-step explanation:</u>

$\text{A geometric sequence is represented by:}\ a_n = a_1 (r)^{n-1}\\\text{where}\ a_1\ \text{is the first term, r is the common ratio, and n is the term}$

$\text{In the given sequence,}\ a_1=120\ \text{and r} = \dfrac{40}{120}=\dfrac{1}{3}$

$\rightarrow \ a_n=120\bigg(\dfrac{1}{3}\bigg)^{n-1}$

Julia was creating similar triangles in the coordinate plane. The first triangle had a rise of 3 and a run of 10. The second tri

valina [46]

Yes julia is correct the run of the scond similar triangle will be b2=25.

<h3>What are simlilar traingles?</h3>

The similar triangle are those whose three sides or one angle or two sides or two angles one side are equal.

In the given:

Height of first triangle h=3

Base of first traingle =10

Height of second triangle =7.5

The base of second triangle b2 = ?

From the triangle similarity

$\dfrac{h_1}{b_1}=\dfrac{h_2}{b_2}$

$\dfrac{3}{10}=\dfrac{7.5}{b_2}$

$b_2=\dfrac{7.5\times 10}{3}$

$b_2=25$

Thus julia is correct the run of the scond similar triangle will be b2=25.

Suppose we want to choose colors, without replacement, from the colors red, blue, green, and purple.

DerKrebs [107]

The number of ways when the choice is not relevant is 4

<h3>How to determine the number of ways?</h3>

The number of colors are:

Colors, n = 4

The color to choose are:

r = 3

<u>Relevant choice</u>

When the choice is relevant, we have:

$Ways = ^nP_r$

This gives

$Ways = ^4P_3$

Evaluate

Ways = 24

Hence, the number of ways when the choice is relevant is 24

<u>Not relevant choice</u>

When the choice is not relevant, we have:

$Ways = ^nC_r$

This gives

$Ways = ^4C_3$

Evaluate

Ways = 4

Hence, the number of ways when the choice is not relevant is 4

Answer:

C. –x + 8y = 56

Step-by-step explanation:

Write in standard form.

x − 8 y = − 56

This is a linear function in the slope - intercept form:

y = m x + b and we need a standard form:

a x + b y = c

y = 1/8 x + 7 / * 8 ( we will multiply both sides of equation by 8 )

8 y = x + 56

- x + 8 y = 56 / * ( - 1 )

x - 8 y = - 56

The equation is y = 1/8x + 7

Standard form equation is Ax + By = C, where A > = 0.

First eliminate the fractions by multiplying the equation by 8

8y = x + 56

Subtract x from each side

-x + 8y = 56

SInce x coeficient can't be negative multiply the equation by negative one.

x - 8y = -56
