What is the median, first and third Interquartile, IQR, and range for 12,19,24,26,31,38,53?

If ad and bd are tangent to circle c, and ad= 13 and bd= 4x-3, then the value of x is 4 or 4.5

To solve this problem, we'll need to use some geometry and algebra.

Using the Pythagorean theorem, we can set up two equations:

OA² + AD² = OD² (for right triangle OAD)

OB² + BD² = OD² (for right triangle OBD)

In these equations, "OD" is the radius of the circle. We don't know this value yet, but we can express it in terms of "x" using the fact that "BD" = 4x-3.

Now, we can simplify these equations by substituting in the values we know. We get:

OA² + 13² = OD²

OB² + (4x-3)² = OD²

This means we can set up the equation:

OA = OB

Now we can substitute in the expressions we found for "OA" and "OB" earlier:

√(OD² - 13²) = √(OD² - (4x-3)²)

We can then square both sides to eliminate the square roots:

OD² - 13² = OD² - (4x-3)²

Simplifying this equation, we get:

169 = (4x-3)²

Taking the square root of both sides (and remembering to include the positive and negative solutions), we get:

4x-3 = ±13

Solving for "x," we get two possible values:

x = 4

x = 4.5

The required answer is CO2 emissions in 6 years = 583,500 metric tons.

Based on the information given, we know that Belmont is a growing industrial town and that every year the level of CO2 emissions from the town increases by 10%. If the town produced 330,000 metric tons of CO2 this year, we can use this information to calculate how much CO2 will be produced in 6 years.

To do this, we can use the formula:
CO2 emissions in 6 years = CO2 emissions this year x (1 + growth rate)^number of years

Compound interest means that interest is earned on prior interest in addition to the principal. Due to compounding, the total amount of debt grows exponentially, and its mathematical study led to the discovery of the number e. In practice, interest is most often calculated on a daily, monthly, or yearly basis, and its impact is influenced greatly by its compounding rate.

The rate of interest is equal to the interest amount paid or received over a particular period divided by the principal sum borrowed or lent.
In this case, the growth rate is 10% per year and the number of years is 6. So, plugging in the numbers we get:

CO2 emissions in 6 years = 330,000 x (1 + 0.1)^6
CO2 emissions in 6 years = 330,000 x 1.77
CO2 emissions in 6 years = 583,500 metric tons

Therefore, if the town continues to grow at the same rate, it will produce 583,500 metric tons of CO2 in 6 years. This is an increase of 253,500 metric tons from the current level of emissions.

To find the linearization L(x) of the function f(x) = 7cos(x) at a = 3.14159265359, we'll use the formula:

L(x) = f(a) + f'(a)(x - a)

where f'(x) is the derivative of f(x) with respect to x.

First, let's find the value of f(a) at a = 3.14159265359:

f(a) = 7cos(a)
f(3.14159265359) = 7cos(3.14159265359) ≈ -7

Next, let's find the value of f'(a) at a = 3.14159265359:

f'(x) = -7sin(x)
f'(a) = -7sin(a)
f'(3.14159265359) = -7sin(3.14159265359) ≈ 0

Now we have all the pieces we need to plug into the formula for L(x):

L(x) = f(a) + f'(a)(x - a)
L(x) = -7 + 0(x - 3.14159265359)
L(x) = -7

So the linearization of the function f(x) = 7cos(x) at a = 3.14159265359 is:

L(x) = -7

To find the linearization L(x) of the function f(x) = 7cos(x) at a specific point a, we'll use the formula:

L(x) = f(a) + f'(a)(x - a)

Given that a = 3.14159265359 (approximating π), first we need to find f(a) and f'(a).

1. f(a) = 7cos(a) = 7cos(3.14159265359) ≈ -7
2. To find f'(x), we take the derivative of f(x):
f'(x) = -7sin(x)

Now, we can find f'(a):
f'(a) = -7sin(3.14159265359) ≈ 0

Finally, we can plug these values into the linearization formula:
L(x) = -7 + 0(x - 3.14159265359)

Simplifying, we get:

L(x) = -7

The equations that have the same value of x as 3/5 (30 x - 15) = 72 are C, D, and E.

To solve for x in 3/5 (30 x - 15) = 72, we can first simplify the left side by distributing the 3/5:

3/5 (30 x - 15) = 18 x - 9

Now we can solve for x by setting the right side equal to 72:

18 x - 9 = 72

Adding 9 to both sides:

18 x = 81

Dividing by 18:

x = 4.5

So we know that option E is one of the correct answers.

To check which of the other options have the same value of x, we can substitute x = 4.5 into each equation and see if it simplifies to 72:

A. 18 x - 15 = 72

18(4.5) - 15 = 72

81 - 15 = 72 (not equivalent)

B. 50 x - 25 = 72

50(4.5) - 25 = 200 - 25 = 175 (not equivalent)

C. 18 x - 9 = 72

18(4.5) - 9 = 72 (equivalent)

D. 3 (6 x - 3) = 72

3(6(4.5) - 3) = 3(24) = 72 (equivalent)

Therefore, the equations that have the same value of x as 3/5 (30 x - 15) = 72 are C, D, and E.

650 adult tickets were sold.

Let's denote the number of adult tickets sold by A and the number of child tickets sold by C.

From the problem, we know that:

A + C = 1000 (the total number of tickets sold is 1000)

8.50A + 4.50C = 7100 (the total revenue from ticket sales is $7100)

We can use the first equation to solve for A in terms of C:

A = 1000 - C

Substituting this expression for A into the second equation, we get:

8.50(1000 - C) + 4.50C = 7100

Expanding and simplifying:

8500 - 8.50C + 4.50C = 7100

4C = 1400

C = 350

So 350 child tickets were sold. We can use the first equation to find the number of adult tickets sold:

A + 350 = 1000

The total area of the flag is the sum of the areas of the three stripes and the percentage of the flag that is gold is approximately 0.459%

Let's call this height "h".

We also know that the side lengths of the flag are in the ratio 2:3. This means that if the shortest side is 2x, then the longest side is 3x. Since the three stripes are of equal height, each one must be h/3 in height.

Now we can use this information to find the area of the gold-colored disk and the total area of the flag. The area of a circle is given by the formula A = πr^2, where r is the radius. Since the diameter is equal to the height of the center stripe (which is h/3), the radius of the disk is h/6. So the area of the disk is:

A_disk = π(h/6)^2 = πh^2/36

The total area of the flag is the sum of the areas of the three stripes. Since each stripe is h/3 in height and the shortest side is 2x, the area of each stripe is:

A_stripe = (2x)(h/3) = 2hx/3

So the total area of the flag is:

A_flag = 3(A_stripe) = 6hx

To find the percentage of the flag that is gold, we need to divide the area of the gold-colored disk by the total area of the flag and multiply by 100.

percentage = (A_disk / A_flag) x 100

Substituting our expressions for A_disk and A_flag, we get:

percentage = (πh^2/36) / (6hx) x 100

Simplifying, we can cancel out the factor of h and get:

percentage = (π/216)x100

So the percentage of the flag that is gold is approximately 0.459% (rounded to three decimal places).

where d is the total distance traveled (in miles). We can also use the formula:

d = r * t

where r is the speed of the helicopter (100 mph) and t is the time taken for the flight (3.8 hours). Substituting this into the first two equations, we get:

x = d * cos(558°)

y = d * sin(558°)

d = r * t = 100 * 3.8 = 380 miles (rounded to the nearest mile)

Substituting the values of d and the angle into the equations for x and y, we get:

x = 380 * cos(558°) ≈ -175.5 miles

y = 380 * sin(558°) ≈ 299.1 miles

Note that the negative sign for x indicates that the helicopter traveled west, not east. We can take the absolute value of x to get the distance traveled east:

|x| ≈ 175.5 miles

Therefore, the helicopter traveled approximately 175.5 miles east and 299.1 miles south.

F(x) and G(x) are polynomial functions in which the expression f(x) + g(x) is always a polynomial and f(x)/g(x) is sometimes a polynomial.

Let F(x) be a polynomial = 2x + 4

g(x) be a polynomial = 6x² + 12x

putting the value in the expression

f(x) + g(x) = 2x + 4 + 6x² + 12x

f(x) + g(x) = 6x² + 14x + 4

6x² + 14x + 4 is a polynomial

Now, putting the value in the equation

f(x)/g(x) = 2x + 4/6x² + 12x

Taking 3x common from 6x² + 12

We get 3x(3x+4)

f(x)/g(x) = 2x+4/3x(2x+4)

f(x)/g(x) = 1/3x

1/3x is not a polynomial

Hence, it sometimes a polynomial.
