A line graph is a type of chart used to show information that changes over time.

The line graph is given below.

A line graph or line plot or a line chart is a graph that uses lines to connect individual data points. It displays quantitative values over a specified time interval.

We have,

2 | x + 2 | ≤ 14

We have to substitute x = 1,2,3,4,5,..... such that it is less than or equal to 14.

      x           1     2     3     4     5        

2 | x + 2 |     6    8     10   12    14

Since we need 2 | x + 2 | to be less than or equal to 14 we can take the x values up to 5 only.

Now,

We will plot the line graph and it is given below.

Thus the line graph is given below.

Answer:

To answer this question, we need to understand the basic concepts of profit and loss in business transactions. Profit or loss is always calculated on the cost price of an item. If the selling price is more than the cost price, it's a profit. If the selling price is less than the cost price, it's a loss.

In this case, Dhurba sells a book for Rs. 483 and incurs a loss of 8%. This means that Rs. 483 is 92% of the cost price (since 100% - 8% = 92%). We can represent this relationship mathematically as:

483 = 0.92 * Cost Price

To find the cost price, we divide both sides of the equation by 0.92:

Cost Price = 483 / 0.92

After performing this calculation, we find that the cost price of the book is approximately Rs. 525.

So, the cost price of the book is Rs. 525.

Now, to find out at what price Dhurba should sell the book to gain a profit of 4%, we need to calculate what is 104% of the cost price (since 100% + 4% = 104%). We can represent this relationship mathematically as:

Selling Price = 1.04 * Cost Price

Substituting the value of Cost Price that we calculated earlier:

Selling Price = 1.04 * 525

After performing this calculation, we find that to gain a profit of 4%, Dhurba should sell the book for approximately Rs. 546.

So, to gain a profit of 4%, Dhurba should sell the book for Rs. 546.

Answer:

Rs 546

Step-by-step explanation:

Solution Given:

Selling price = Rs. 483

Loss = 8%

We can use the formula to find the cost price:

Cost price = Selling price+loss % of cost price

Cost price- loss % of cost price=Selling price

Cost price(1-8%)=483

Cost price*0.92=483

Cost price=483/0.92

Cost price = Rs 525

Therefore the cost price is Rs 525.

Cost price = Rs. 525

Gain = 4%

We can use the formula to find the new selling price:

Selling price = cost price+ gain% of cost price

Selling price=525+4% *525

Selling price =Rs 546

Therefore, the cost price of the book is Rs. 525 and the selling price to gain 4% is Rs. 546.

Step-by-step explanation:

Given expression:

\(\implies \dfrac{2y-1}{y^2+4y}-\dfrac{y-2}{y^2+2y-8}\)

Factor the denominators of both fractions:

\(\implies \dfrac{2y-1}{y(y+4)}-\dfrac{y-2}{y^2+4y-2y-8}\)

\(\implies \dfrac{2y-1}{y(y+4)}-\dfrac{y-2}{y(y+4)-2(y+4)}\)

\(\implies \dfrac{2y-1}{y(y+4)}-\dfrac{y-2}{(y-2)(y+4)}\)

Cancel the common factor (y - 2) of the right fraction:

\(\implies \dfrac{2y-1}{y(y+4)}-\dfrac{1}{(y+4)}\)

Adjust the fractions based on the LCM of y(y + 4):

\(\implies \dfrac{2y-1}{y(y+4)}-\dfrac{y}{y(y+4)}\)

\(\textsf{Apply the fraction rule} \quad \dfrac{a}{c}-\dfrac{b}{c}=\dfrac{a-b}{c}:\)

\(\implies \dfrac{2y-1-y}{y(y+4)}\)

Using continuous compounding, the principal investment was $1310

What is compound interest?

Compound interest is the interest earned on both the principal amount and the accumulated interest from previous periods.

We can use the formula for continuous compounding to solve this problem:

A = P\(e^{rt}\)

where A is the amount of money in the account after t years, P is the principal investment, r is the annual interest rate, and e is Euler's number (approximately 2.71828).

We know that Bob invested his money at an interest rate of 2% for 9 years and that the final amount in the account was $1568.35. Substituting these values into the formula, we get:

1568.35 = P\(e^{0.02*9}\)

1568.35 = P\(e^{0.18}\)

P = 1568.35 / \(e^{0.18}\)

P = 1568.35 / 1.197

P ≈ $1309.99

Therefore, the principal investment was $1309.99 approximately $1310.

The resulting graph is a circle with center at (-3,-1) and radius 3.

The graph of the equation (x+3)²+(y+1)²=9

is a circle with center at (-3,-1) and radius 3. The equation of a circle with center (a,b) and radius r is given by the equation (x-a)² + (y-b)² = r². By comparing the given equation with the standard equation of a circle, we can easily see that the center of the circle is (-3,-1) and the radius is 3. To graph a circle, we need to first plot the center of the circle, which is (-3,-1) in this case. Next, we need to mark the radius of the circle, which is 3 units. We can do this by measuring 3 units from the center in any direction and marking the point. Since the radius of the circle is the same in all directions, we can repeat this process for other directions to get points on the circumference of the circle. We can use a compass to make this process easier. After plotting a sufficient number of points, we can draw a smooth curve passing through all the points to obtain the graph of the circle.

The percentage of the can that is not occupied by tennis balls is approximately 80.14%.

We have,

The volume of the can = The volume of the cylinder - The volume of the three tennis balls.

The volume of the cylinder.

V(cylinder) = πr²h

where r is the radius and h is the height of the cylinder.

Since the can holds three tennis balls snugly, the height of the cylinder is equal to three times the diameter of a tennis ball.

= 3 × 2(3.5 cm)

= 21 cm.

V(cylinder)

= π (3.5 cm)² (21 cm)

= 2709.38 cm³

The volume of one tennis ball.

V (ball) = (4/3)πr³

where r is the radius of the tennis ball. Thus,

V(ball) = (4/3)π(3.5 cm)³ = 179.594 cm³

The total volume of the three tennis balls is:

V(3balls) = 3 V(ball)

= 3(4/3) π (3.5 cm)³

= 538.782 cm³

The volume of the can not be occupied by tennis balls.

V(not occupied) = V(cylinder) - V(3 balls)

= 2709.38 - 538.782

= 2170.598 cm³

The percentage of the can that is not occupied by tennis balls.

percentage = (V(not occupied / V(cylinder)) × 100%

= (2170.598 cm^3/2709.38 cm^3) × 100%

= 80.14%

Therefore,

The percentage of the can that is not occupied by tennis balls is approximately 80.14%.

bTo determine the percent of the original price you end up paying after the discounts, we can calculate the final price as a percentage of the original price.

Let's assume the original price of an item is $100.

The first discount reduces the price by 50%, so the price after the first discount is 50% of the original price, which is $100 * 0.5 = $50.

The second discount of 45% is applied to the price after the first discount. The price after the second discount is 45% of $50, which is $50 * 0.45 = $22.50.

Therefore, the final price you end up paying after both discounts is $22.50.\

To find the percent of the original price you end up paying, we divide the final price by the original price and multiply by 100:

Percent of original price = (final price / original price) * 100

In this case, the final price is $22.50 and the original price is $100:

Percent of original price = ($22.50 / $100) * 100

                       = 0.225 * 100

                       = 22.5%

Therefore, you end up paying 22.5% of the original price after the discounts.

It's important to note that the percent of the original price you end up paying will depend on the original price of the item. The calculations above were based on the assumption that the original price was $100. If the original price is different, the resulting percentage will vary accordingly.

Answer:

x = 150°

Step-by-step explanation:

From the picture attached,

Segment AC and segment BC are the tangents to circle O.

By the property of angle between tangent and the radius of a circle,

"Angle between the radius and tangent drawn to the circle is 90°"

m(∠OAC) = m(∠OBC) = 90°

Sum of opposite angles of the quadrilateral OBCA is 180°,

m(∠OAC) + m(∠OBC) = 180°

Therefore, quadrilateral OBCA is a cyclic quadrilateral.

By the same property of cyclic quadrilateral,

m(∠AOB) + m(∠ACB) = 180°

x° + 30° = 180°

x = 180 - 30

x = 150°

Answer:

x =23

Step-by-step explanation:

ok first, the full degree of a straight line is 180°

subtract 38° out of 180°

180-38= 142

so 6x+4= 142°

subtract 4 from both sides of the equation

6x +4 -4= 142-4

6x=138

divide 6 from 6x and 138

x=23

Therefore, the painting should be placed 5/4 feet on each side of the wall.

In the given problem, a 5-foot wide painting should be centered on a 15-foot wide wall. We can determine the length of each side of the painting by subtracting x from each side of the wall.

Therefore, the left side of the equation can be written as:

\(15 - x - 5 - x\)

The physical situation given is that the painting is to be centered on the wall. This means that each side of the wall will have the same amount of space as the painting.

Therefore, the length of each side of the painting can be determined by subtracting x from each side of the wall. The total width of the wall is 15 feet, and the painting is 5 feet wide.

Therefore, the total length of the space on each side of the painting is 5 + x.To find the value of x, we can equate the length of each side of the painting. Therefore, the equation can be written as:

\(15 -x - 5 - x = 5 + x + x\)

Simplifying the equation, we get:

\(10 - 2x = 2x + 5\)

Solving for x, we get:

\(4x = 5x = \frac{5}{4}\)
