The radius of the circle is 36 centimetres.

The circumference of the circle is  75.36 centimetres.

Let's find the radius of the circle with 20 degrees arc and length of 4π centimetres.

Length of an arc = ∅ / 360 × 2πr

where

Therefore,

Length of an arc  = 20 / 360 × 2 × π × r

4π = 40πr / 360

4π = 1 / 9 πr

cross multiply

πr = 36π

divide both sides by π

r = 36 centimetres

radius = 36 centimetres

b.

The equilateral triangle is inscribed in the circle. Therefore, the circumference of the circle can be found as follows:

The radius of the circle can be found using trigonometric ratios as follows:

The radius is an angle bisector. Hence,

sin 30 = opposite / hypotenuse

0.5 = 6 / r

cross multiply

r = 6 / 0.5

r = 12 centimetres

Lets' find the circumference,

circumference of the circle = 2πr

circumference of the circle = 2 × π × 12

circumference of the circle = 24 × 3.14

circumference of the circle = 75.36 cm

The virus will thus increase from 160 to 600 in around 10 days.

A virus is a submicroscopic infectious agent that only reproduces inside of an organism's live cells.

We can resolve this issue using a proportion. Let x be the period of time needed for the virus to multiply from 160 to 600. Then: (240 - 160) / 18 = (600 - 160) / x

This equation may be written as

80/18 = 440/x.

Cross-multiplying:

80x = 18 * 440

80 divided by both sides yields x = 9.9

We obtain x = 10 by rounding to the next full value.

Therefore, The virus will thus increase from 160 to 600 in around 10 days.

The electricity cost for the Val's AC to run for a summer month of 30 days is $84.

Given that,

Val's whole-house central air conditioner uses 4,000 watts when running.

Val runs the AC 7 hours per summer day.

Electricity costs (10 cents)/(1 kilowatt-hour).

Total electricity used for the whole house = 4000 watts = 4 kilowatts

Number of hours that the AC runs = 7 hours

Cost of electricity = (10 cents)/(1 kilowatt-hour).

Cost of electricity for 4 kilowatts for 1 hour = 10 × 4 = 40 cents

Cost of electricity for 4 kilowatts for 7 hours = 40 × 7 = 280 cents

                                                                                       = $2.80

Cost of electricity for a summer month of 30 days = $2.80 × 30

                                                                                   = $84

Hence the total cost for the electricity is $84.

The factor form of the given expression is [tex]x^2 - 14 - 4x = (x - 4)(x - 14).[/tex]

To factor the expression x^2 - 14 - 4x, we can use the technique of grouping.

First, we can rearrange the terms as:

x^2 - 4x - 14

Next, we can factor out a common factor of x from the first two terms:

x(x - 4) - 14

Then, we can factor out a negative 1 from the last two terms:

x(x - 4) - 1(14)

Finally, we can write the expression as the product of two binomials:

(x - 4)(x - 14)

Therefore, the factored form of x^2 - 14 - 4x is (x - 4)(x - 14).

There is only one way for the doctor to visit all seven patients exactly once.

A combination is a way of selecting items from a larger set, where the order of the items is not important. In this problem, we need to select seven patients out of a larger set of seven patients, so we can use the formula for the number of combinations of n items taken r at a time:

C(n,r) = n! / (r!(n-r)!)

where n is the total number of items, r is the number of items to be selected, and the exclamation mark represents the factorial function.

In this case, we need to find the number of combinations of 7 patients taken 7 at a time, which can be written as:

C(7,7) = 7! / (7!(7-7)!) = 7! / (7!0!) = 1

The order in which she visits the patients does not matter since each patient is visited only once.

The equation |x| = 9 has two solutions: x = 9 and x = -9. The shaded region includes all points to the left of -9 and all points to the right of 9.

The equation is given as follows:

|x| = 9

The equation |x| = 9 has two solutions: x = 9 and x = -9.

To check these solutions, we can substitute them back into the original equation and see if they satisfy it:

|x| = 9

|9| = 9 --> True

|-9| = 9 --> True

Therefore, the solutions x = 9 and x = -9 are both valid.

To graph the solution(s), we can draw a number line and mark the points x = 9 and x = -9 with closed circles (since the absolute value of x is equal to 9 at those points).

We can then shade the parts of the number line where the absolute value of x is greater than or equal to 9.

This includes all points to the right of 9 and all points to the left of -9.

[tex]\large\textrm{There are two solutions: 9 and -9.}[/tex]

Further explanation

If we have the absolute value of x, that means x could be positive or negative.

This means that, in |x| = 9, x could be 9 or -9.

 Plug the answers into the original equation.

You should get a true statement.

because the absolute value of 9 is 9 so that's a solution

the absolute value of -9 is also 9 so that's also a solution

therefore, the solutions are 9 and -9.

The jet can fly a distance of 192,000 miles in a day, assuming it can maintain a speed of 8 x 10³ miles per hour for 24 hours.

There are 24 hours in a day, so the distance the jet can fly in a day is:

Distance = Speed x Time

where Time is the duration of the flight.

If we assume that the jet can fly continuously for 24 hours without refueling or stopping, then the time of the flight is 24 hours.

Therefore, we have:

Distance = Speed x Time

=8 x 10³ miles/hour x (24 hours)

= 192,000 miles

The number of sides of a polygon that has 18 triangles would be 20 sides.

To determine the number of sides in a polygon consisting of 18 triangles, we can calculate the sum of the interior angles. Each triangle has total interior angle sum of 180 degrees, and since there are 18 triangles, the sum of those angles would be 18 multiplied by 180, which comes to 3, 240 degrees.

Applying the given formula for calculating the interior angles of a polygon, we obtain that (n - 2) multiplied by 180 stands for the sum of all angles within it, with n being the number of sides.

Hence, rearranging the equation gives n :

n = (sum of interior angles ÷ 180) + 2

n = (3240 ÷ 180) + 2 = 20

The cost price of the article, which is sold for Rs. 150 at a gain but if sold for Rs. 135 would have resulted in a loss equal to 50% of the original gain, is Rs. 127.50.

The cost price is the difference between the selling price and the profit or gain.

The difference is determined by subtraction.

Selling price of the article = Rs. 150

Loss if sold at Rs. 135 = 50% of the original gain

Original gain = Rs. 15 (Rs. 150 - Rs. 135)

50% of the original gain = Rs. 7.50 (Rs. 15 x 50%)

Cost price of the article = Rs. 127.50 (Rs. 135 - Rs. 7.50)

In the given system of linear equations we get,

3x - y = 4, 6x - 2y = 8 has no solution.

y = -4x - 5, y = -4x + 1 has infinitely many solutions.

- 3x + y = 7, 2x - 4y = -8 has exactly one solution.

System of linear equations can have one solution or infinitely many solution or no solution based on their form.

If two lines are parallel to each other (that is, both linear equations have same slope) then the system of linear equations has no solutions.

A system of linear equation with infinitely many solutions has both the sides of equations equal.

When a system of linear equation has exactly one value of the variables which makes the equations satisfy is said to have one solution.

Here the system of linear equations are as,

3x - y = 4

6x - 2y = 8

The two equations of the system of linear equations are parallel to each other and hence has no solution.

y = -4x - 5

y = -4x + 1

The two equations of the system of linear equations has both the sides equal to each other and hence has infinitely many solutions.

- 3x + y = 7

2x - 4y = -8

The two equations of the system of linear equations has exactly one value of x and y which satisfies the conditions and hence has one solution.

Step-by-step explanation:

To determine the minimum area of the piece of fabric Jonna needs, we need to calculate the diameter of the circle after adding 2 inches to the radius.

The radius of the pillow is half its diameter, which is 15/2 = 7.5 inches.

When Jonna adds 2 inches to the radius, the new radius becomes 7.5 + 2 = 9.5 inches.

The diameter of the circle with the new radius is 2 x 9.5 = 19 inches.

Therefore, Jonna needs to cut a circular piece of fabric with a diameter of 19 inches.

To calculate the minimum area of the fabric, we need to use the formula for the area of a circle:

Area = π x (radius)^2

The radius is 9.5 inches, so:

Area = π x (9.5)^2

Area = π x 90.25

Area ≈ 283.77 square inches

Therefore, Jonna needs a piece of fabric with a minimum area of approximately 283.77 square inches.
