Given the series:

[tex]1-\frac{1}{3}+\frac{1}{9}-...[/tex]

State if the series is convergent or divergent and if convergent, find its sum.

The sequence of terms forms a geometric pattern. Each term is found by multiplying the previous term by a constant number (the common ratio).

Let's find the value of the common ratio by dividing any two successive terms, for example:

[tex]r=\frac{-\frac{1}{3}}{1}=-\frac{1}{3}[/tex]

The common ratio is greater than -1 and less than 1, so the series is convergent.

Now we find the sum of the infinite series by using the formula:

[tex]S=\frac{t_1}{1-r}[/tex]

Where t1 is the first term, that is, t1 = 1.

Substituting:

[tex]S=\frac{1}{1-\left(-\frac{1}{3}\right)}[/tex]

Now we add the numbers to the denominator:

[tex]S=\frac{1}{1+\frac{1}{3}}[/tex]

We have a sum of an integer and a fraction:

[tex]1+\frac{1}{3}[/tex]

To add these numbers, we must get them to have the same denominator, thus:

[tex]1+\frac{1}{3}=\frac{3}{3}+\frac{1}{3}=\frac{4}{3}[/tex]

Operating:

[tex]S=\frac{1}{\frac{4}{3}}[/tex]

To divide by a fraction, we multiply by its reciprocal:

[tex]S=1\cdot\frac{3}{4}=\frac{3}{4}[/tex]

What does the y-intercept mean in this situation?
For every additional mile the cab travels, the total fee increases by $10.00.
For every additional mile the cab travels, the total fee increases by $1.50.
When the cab travels 0 miles, the total fee will be $1.50.
When the cab travels 0 miles, the total fee will be $10.00.

Answers

The y-intercept of the total fee paid by Tyrell on his trip to Chicago when the cab travels 0 miles, the total fee will be $10.00.

What is the y-intercept?

The total fee paid by Tyrell is made up of a fixed cost and a variable cost. The fixed fee is the fee that is incurred regardless of the miles travelled. The variable fee is the fee that changes with the distance travelled.

The total fee paid can be modelled as a linear function. A linear function is a single variable that is raised to the power of one.

Total fee = fixed fee + variable fee

Variable fee = (change in total fee ) / (change in total miles)

(17.50 - 13) / (5 - 2)

4.50 / 3 = 1.50

Fixed fee = $13 - (1.50 x 2)

$13 - 3 = $10

The fixed fee, $10 is equivalent to the y-intercept.

An elevator ascends at a rate of 29.6 feet per second. If a building is 1,450 feet tall,
about how long would it take for the elevator to travel from the ground floor to the roof?
OA. 0.49 minute
O B. 0.82 minute
OC. 4.9 minutes
OD. 8.2 minutes

Answers

Elevator will take 0.82 minute for travel from the ground floor to the roof. (Option B is correct).

rate by an elevator ascends = 29.6 feet per second

height of the  building = 1,450 feet

Time to travel from the ground floor to the roof is calculated as :

we use rate formula.

i.e

rate = distance/ time

time = distance/rate

time = 1450/ (29.6 feet/sec )

time = 1450/29.6

       = 48.98sec

as we know

60 second = 1mint

1 second = 1/60 minutes

therefore,

 time = (48.98 / 60) minutes

time = 0.8163

time = 0.812 minutes

Elevator will take 0.82 minute for travel from the ground floor to the roof. (Option B is correct).

A prism with a volume of 3125 ft³ is scaled down to a volume of 200 ft³.What is the scale factor?

Answers

3) In general, a dilation is an enlargement of the sides of a shape, even if it is a 3D shape.

Furthermore, the volume of a prism is given by the formula

[tex]V=A_{\text{base}}\cdot h=l\cdot w\cdot h[/tex]

Then,

[tex]V_{\text{new}}=3l\cdot3w\cdot3w=3^3(l\cdot w\cdot h)=27V_{initial}[/tex]

Therefore,

[tex]\Rightarrow V_{\text{new}}=27\cdot(270)=7290[/tex]

The answer to part 3) is 7290 m^3

4) Due to similar reasoning, in general, the area of a shape is given by

[tex]A=l\cdot w[/tex]

If we apply a dilation to that area,

[tex]\Rightarrow A_{\text{new}}=kl\cdot kw=k^2A_{original}[/tex]

Where k is the dilation factor.

Thus, in our case,

[tex]\begin{gathered} \Rightarrow A_{\text{new}}=(54)^2\cdot8=23328 \\ \text{and} \\ h_{\text{new}}=54\cdot6=324 \end{gathered}[/tex]

Therefore,

[tex]\Rightarrow V_{\text{new}}=A_{\text{new}}\cdot h_{\text{new}}=23328\cdot324=7558272[/tex]

The answer to part 4) is 7558272 cm^3

5) From the answer to question 3)

[tex]V_{\text{new}}=k^3\cdot V_{original}_{}[/tex]

Thus,

[tex]\begin{gathered} \Rightarrow3125=k^3\cdot200 \\ \Rightarrow k^3=\frac{3125}{200}=\frac{125}{8} \\ \Rightarrow k=\frac{5}{2}=2.5 \\ \Rightarrow k=2.5 \end{gathered}[/tex]

First, we need to find the sample space for two dice. Since each dice has 6 faces, the sample space is

which consist in 36 elements.

Part A.

In this case, we need to find the combinations where the sum of the 2 dice is even. The combinations are:

for instance, in the upper left corner, the sum is 1+1=2, which is an even number and similarly for the other cases.

As we can note, there are 18 possible combinations. Then, the probability is

[tex]P(\text{ even sum)=}\frac{18}{36}=\frac{1}{2}[/tex]

Part B.

In this case, we need to find the possible combinations where the sum of the 2 dices is greater than 7. The possible combinations are:

Since there are 15 possible combinations, the probability is given by

[tex]P(\text{ Sum greater than 7)=}\frac{15}{36}[/tex]

Part C.

This case is the intersection of the two cases from above. The possible combinations are:

Since there are 9 possible combinations, the probability is

[tex]P(\text{Even sum and sum greater than 7)=}\frac{9}{36}=\frac{1}{4}[/tex]

Part D.

We need to find the possible combinations where the sum is even or the sum is greater than 7. Then, this case is the union of case A and B. Then the possible combinations are:

Since there are 18+6=24 combinations, the probability is

The mark up percentage was %.

Answers

The percentage of the dealer markup from the original price will be; 1.24 %

What is the percentage of the total value?

Suppose the value of which a thing is expressed in percentage is "a Suppose the percent that considered thing is of "a" is b%. Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part into 100 parts; then we multiply it by b so that we collect b items per 100 items(that is exactly what b percent means).

Given that the original price of a gold, watch was $500. And the dealer sells this item for $620.

Then the percentage of the dealer markup from the original price will be;

The change = amount/ original  x 100%

= 620/ 500  x 100%

2             $408            $400         Jessica earns more

3             $416             $400         Jessica earns more

Step-by-step explanation:

At simple interest, the amount of interest is the same each year

First year: Since compounding takes place only at the end of the year, both of them earn the same amount of interest

Interest earned = 20,000 x 0.02 = $400

Same for both boxes for first year

Both of their deposits will increase by $400 to $20,400

For second year
Jessica's interest is calculated on 20,400 = 20,400 x 0.02 = $408
Her deposit value at the end of year 2 = 20, 400 + 408 = $20,808

Tom's interest is calculated on the original deposit since it is simple interest. So in year 2, Tom still makes $400.

In year 2 Jessica earns more interest than Tom
Jessica: $408
Tom : $400

For third year, Jessica's interest is calculated on her deposit value of 20,800 = 20,800 x 0.02 = $416

Tom's interest for 3rd year is the same as for the previous years = $400

So in third year, Jessica earns more

Explanation:

First, we need to draw the triangle to identify the hypotenuse, so using the points P(-2, 5), Q(5, 2), and R(8, 9), we get:

Therefore, the hypotenuse is side PR.

Then, the midpoint of a segment that goes from (x1, y1) to (x2, y2) is

[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

So, replacing (x1, y1) = P(-2, 5) and (x2, y2) = R(8, 9), we get that the midpoint of the hypotenuse is

For a discontinuous function ,maximun value is found by replacing every region for the values x ,y

So then for x≤2. and y≤1 and f(x,y) = x +y

theres a maximum value but no minimum ( because is minus infinite). The maximum value for this area is

x+y = 2+1= 3

Now for area y ≥-2x -3

rearrange the equation as y+2x ≥ -3

is the equation of a plane , the plane or area that goes over the straight line y= -2x-3.

So now replace y = -2x-3 in the function f(x,y) = x+y

then f(x,y)= x -2x-3 = -x-3

Now the third region is y≥ 2x -3

this is the area over a line with slope positive equal to 2

now replacing again for this area we find

f(x,y) = x+y = 2x-3 +x = 3x -3

because x≤2. So then replace x by 2 in f(x,y) to find the maximum value

f(x,y) in 2nd region is f(x,y) = -x-3= -2-3= -5

f(x,y) in 3rd region is f(x,y) = 3x -3= 3•2 -3= 3

Answers

We know that

• The ball is dropped from 1600 meters high.

,

• Each time it bounces 3/4 of its original height.

This situation creates a geometric sequence where the reason is 3/4. To find the first three terms of this sequence, we just have to multiply each term with 3/4. We know that the first term is 1600.

[tex]1600\cdot\frac{3}{4}=\frac{4800}{4}=1200[/tex]

The second term is 1200 meters.

[tex]1200\cdot\frac{3}{4}=\frac{3600}{4}=900[/tex]

The third term is 900.

To find an equation, we have to use the geometric sequence formula-

[tex]a_n=a_1\cdot r^{n-1}[/tex]

Replacing the information we have the equation that represents the situation of this problem.

[tex]a_n=1600\cdot(\frac{3}{4})^{n-1}[/tex]

At last, the height after 4 bounces is

[tex]900\cdot\frac{3}{4}=\frac{2700}{4}=675[/tex]

The height of the third bounce is 675 meters.

Answers

Answer:

38.26% prefer comedies

If 350 people are asked, 134 people will prefer comedies

Explanation:

First, we need to find the percentage of people that prefer comedy. Taking into account the table, 44 people prefer comedy from the 115 people in total.

So, the percentage of students that prefer comedy is calculated as

44/115 x 100% = 0.3826 x 100% = 38.26%

Then, if 350 are asked about their favorite movie genres, the number of people that will prefer comedies is equal to 350 people times the percentage calculated before, so

350 x 38.26% = 350 x 0.3826 = 133.9 = 134

Therefore, 134 people will prefer comedies.

a. The linear equation that models the price-sales relationship is: y = -500x + 5000

b. daily sales: $1,250.

How to Write a Linear Equation that Models a Relation?

To write the linear equation for a relationship, find the unit rate/slope (m) and the starting value/y-intercept, then substitute the values into y = mx + b.

a. Using two points from the problem, (6, 2000) and (8, 1000), find the unit rate (m):

Unit rate (m) = change in y / change in x = (2000 - 1000)/(6 - 8)

Unit rate (m) = 1000/-2

Unit rate (m) = -500

Find the y-intercept (b) by substituting m = -500 and (x, y) = (6, 2000) into y = mx + b:

2000 = -500(6) + b

2000 = -3000 + b

2000 + 3000 = -3000 + b + 3000

5000 = b

b = 5000

To write the linear equation, substitute m = -500 and b = 5000 into y = mx + b:

y = -500x + 5000

b. Substitute x = 7.5 into y = -500x + 5000:

y = -500(7.5) + 5000

y = -3750 + 5000

y = 1,250

The daily sales would be $1,250.
