Does the series converge or diverge? If it converges, what is the sum? Show your work

Answers

Answer 1

The series is a convergence series and the sum of the series is -8/3

The type of the series

The series is given as:

[tex]\sum\limits^{\infty}_{n = 1} -4(-\frac 12)^{n-1}[/tex]

The above series has the following properties:

First term; a = -4Common ratio, r = -1/2

Start by calculating the absolute value of the common ratio

Absolute value = |-1/2|

This gives

Absolute value = 1/2

The above value is less than 1.

It means that the series converges.

The sum of the series

This is calculated using:

[tex]S_{\infty} = \frac{a}{1 -r}[/tex]

So, we have:

[tex]S_{\infty} = \frac{-4}{1 + \frac 12}[/tex]

Evaluate the sum

[tex]S_{\infty} = \frac{-4}{\frac 32}[/tex]

Evaluate the quotient

[tex]S_{\infty} = \frac{-8}{3}[/tex]

Hence, the sum of the series is -8/3

Solve the inequality.

−13x+10>17
Which inequality represents the solutions to this inequality?
a) x<7x<7

b) x>−21x>−21

c) x<−21x<−21

d) x>7x>7

Answers

The solution to inequality is less than the negative of 21. Then the correct option is C.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given below.

−(1/3)x + 10 > 17

Then the solution to the inequality will be

−(1/3)x + 10 > 17

−(1/3)x > 17− 10

−(1/3)x > 7

When the sign is changed then the equality sign also changed.

(1/3)x < −7

x < − 21

The value of x is less than the negative of 21.

Thus, the correct option is C.

Answers

The measure of the angle m1 is 110 degrees

How to determine the measure of angle m1?

The measures of the arcs are given as:

Arc 1 = 130

Arc 2 = 90

The measure of the angle is calculated using:

Angle = 0.5 * (Arc 1 + Arc 2)

So, we have:

Angle = 0.5 * (130 + 90)

Evaluate

Angle = 110

Hence, the measure of angle m1 is 110 degrees

You move left 5 units. You end at (-1, 5). Where did you start?

Answers

Answer:

(4,5)

Step-by-step explanation:

Hello!

If you move 5 units to the left, you change the x-value in (x, y) by -5.

Let the original x-value be x:

x - 5 = -1x = 4

The original x-value is 4. Since you didn't change the y-value (up/down), you can keep the same y-value for the coordinate.

The original point was at (4,5)

Answer:

You started at (4, 5)

Step-by-step explanation:

The first number of coordinate pair is x. you started at the right and THEN moved the the left, as stated in the question. So -1 + 5 is 4.
So you started at (4, 5)

The pythagorean theorem is a²+b²=c²

Given this, we will plug in our numbers like this: 9²+10²=c²

9²+10²=181, but we have to find the square root of that.

c²=√181=13.45, or 13.5

Step-by-step explanation:

We have a right triangle which allows us to use the Pythagorean Theorem

The function f(x) is shown on the graph.

On a coordinate plane, a curved line with 3 arcs, labeled f of x, crosses the x-axis at (negative 2, 0), (negative 1, 0), (1, 0), and (3, 0), and the y-axis at (0, negative 6).

What is f(0)?

0 only
–6 only
–2, –1, 1, and 3 only
–6, –2, –1, 1, and 3 only

Answers

By using the description of the graph, we conclude that f(0) = -6 only.

The correct option is the second one.

What is f(0)?

Here we want to know the value of the function when evaluated in 0. Remember that the points on the graph of the function are of the form:

(x, f(x)).

Now, in the description of the graph you say:

"... and the y-axis at (0, negative 6)."

So we know that the graph passes through (0, -6), which means that when evaluated in 0, the function is equal to -6.

So the correct option is the second one: –6 only

Circle the first line.

His mistake was: He substituted y from 2nd equation in 1st equation incorrectly. There is a minus sign before y and it wasn't taken into the account.

The correct steps are:

2x - y = 18

2x - (4x + 2) = 18

2x - 4x - 2 = 18

-2x - 2 = 18

-2x = 20

x = -10

y = 4x + 2

y = 4(-10) + 2

To find the rate of change, we will use the formula;

Rate of change = (y2 - y1)/(x2 - x1)

From the given table, we can solve for the rate of change by picking two consecutive points to get;

Rate of change = (9.6 - 8.2)/(2 - 0)

Rate of change = 1.4/2

Rate of change = 0.7
