Determine whether each infinite geometric series diverges or converges. The series converges.

If the series converges, state the sum. 1+ 1/4 + 1/16 + . . . .

The sum of the infinite series is 4/3

What is the sum of the infinite series?

Given:

[tex]a(\text{ the first term })=1\\\\r=\frac{a_{2} }{a_{1} } =\frac{1/4}{1} =\frac{1}{4}\\[/tex]

Since   [tex]\vert r \vert < 1[/tex] , the  infinite series converges.  

The sum of infinite geometric series is:

[tex]S_\infty=\frac{a}{1-r} ; -1 < r < 1\\\\S_\infty=\frac{1}{1-\frac{1}{4}}=\frac{4}{3}[/tex]

The sum of the infinite series is 4/3

Correct answer is A. Amal owes Bella  x 3(-2.5)

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Answer:

Step-by-step explanation:

For both graphs to be parallel, the value of a = -1/2.

If two graphs are parallel, their equation expressed in slope-intercept form y = mx + b, will have the same value of m which is the slope of the graphs.

Given, 4 = 3x + 6y, rewrite both equations in slope-intercept form:

4 = 3x + 6y

-3x + 4 = 6y

-3x/6 + 4/6 = 6y/6

-1/2x + 2/3 = y

y = -1/2x + 2/3 [slope (m) = -1/2]

This means that for both graphs to be parallel, the value of a = -1/2.

Ilhan's average speed in the race is 11.03 miles per hour.

The average speed is a scalar measure of the total distance divided by the total time.

The average speed shows an object's displacement rate from one point to another.

Speed measures the rate of fastness, while the average speed shows the average rate of fastness of an object in movement.

The average speed is measured in magnitude without direction as a scalar quantity.

Beginning time for the race = 7:22 am

Ending time for the race = 8:07 pm

Time used = 12hours 45 minutes or 12.75 hours (8:07 pm - 7:22 am)

Swimming 2.4 miles

Cycling 112 miles

Running 26.2 mile

Total distance = 140.6 miles

Average speed = Distance/Time

= 11.03 miles per hour (140.6/12.75)

The expression for the height is given as 3V/pir³

A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the ape-x or vertex.

The formula for calculating the volume of a cone is expressed according to the equation;

V = 1/3pir³h

We are to make h the subject of the formula;

V = 1/3pir³h

Cross multiply

3V = pir³h

Divide both sides by pir³

3V/pir³ = pir³h/pir³

3V/pir³ = h

Answer: 82

Step-by-step explanation:

The missing second term of the given arithmetic sequence is: 2.5.

A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

given: -3, __, 8 is an arithmetic sequence, where a₁ = -3 and a₃ = 8

Now, as [tex]a_n=a_1+(n-1)d[/tex], for the nth term of an arithmetic sequence,

For n = 3, a₃ = -3 + (3 - 1)d

=> 8 = -3 + 2d

=> 11/2 = d

=> d = 5.5

Hence, a₂ will be given as n = 2, in the above formula

=> a₂ = -3 + (2 - 1) (5.5)

=> a₂ = -3 + 5.5

=> a₂ = 2.5

Hence, The missing second term of the given arithmetic sequence is: 2.5.

Step-by-step explanation:

Rate x Time = jobs

Mr. Comb's rate is 1 field in 5 hours or 1/5.

Mr. Ramset's rate is 1 fiend in 4.5 hours.

If we take the time and rate that it takes Mr. Comb's to mow one field and add it to the time and rate that it takes Mr. Ramset's to move one field  we can find out how long it takes them to mow one field together

RT + RT = 1 (job)

1/5T + 1/4.5T = 1  We need a common denominator.  I just multiplied 5 x 4.5  for get 22.5  Rewrite 1/5 and 1/4.5 with a common denominator or 22.5 we get the equivalent fractions that we can add together.

4.5/ 22.5T + 5/22.5T = 1  Add the fractions together

9.5/22.5T = 1  We want to solve for T, so we will multiply both sides of the equation by 22.5/9.5

9.5/22.5(22.5/9.5)T= 1 22.5/9.5

T = 22.5/9.5  When I divide these, I get 2 35/95 hours.  I need to change the fraction part of an hour to minutes.  I will use the unit multiplies 60 minutes/ 1 hour.

35hours/95 (60 minutes/1 Hour) = 22.10526331579.  I need to round this to the nearest minutes which will be 22 minutes.

The Jon's age is 35 years.

We are given the product of ages of both the persons. Also, we are given Jon's age = j years and Laura's age = (j + 3) years. So, representing the given information in mathematical expression form -

j × (j + 3) = 1330

Performing multiplication on Left Hand Side of the equation to find the value of j

j² + 3j = 1330

Shifting 1330 to Left Hand Side of the equation to find the value of j

j² + 3j - 1330 = 0

Solving the mentioned quadratic equation by factorization -

j² + 38j - 35j - 1330 = 0

Further solving the quadratic equation -

j (j + 38) -35 (j + 38) = 0

(j + 38) (j - 35) = 0

j = 35, -38

The length and width of the rectangle is 46 feet and 10 feet respectively.

Let the length of the rectangle be x and the width of the rectangle be y.

Now, the length of the rectangle is 4 less than 5 times its width.

Therefore,

x = 5y - 4

The perimeter of a rectangle is given as two times the sum of its length and breadth.

Perimeter = 2( length + breadth)

P = 2( x + y)

Now, the perimeter of the rectangle is 112 square feet.

Therefore,

112 = 2( 5y - 4 + y)

( 112 /2) = 5y - 4 + y

6y - 4 = 56

6y = 56 + 4

6y = 60

y = ( 60 / 6)

y = 10

Now,

x = 5y - 4

x = 5 × 10 - 4

x = 50 - 4

x = 46

So, the length of the rectangle is x = 46 feet and the breadth of the rectangle is y = 10 feet.

There are 210 ways to write 5 of the letters of the word ALGORITHM in a row if the 2 two letters must be TH

Given data

the word ALGORITHM

the first two letters must be TH

ALGORITHM has 9 letters and order of writing the letters is important, so we use Permutation to solve this

The 2 letters TH are fixed and this reduces the number of letters in the word from 9 to 7. Also, the the first two being fixed reduces the letters arrangement to be 3.

This means that we have the arrangement as follows:

7P3

= 7! / ( 7 - 3 )!

= 7! / 4!

= 7 * 6 * 5 * 4! / 4!

= 7 * 6 * 5
