and 8 white tiles. The tiles cost $0.50 per in.².
What is the total area of the tiles Kaylee needs
to buy?
A = ? in.²

Answer:

Given:

Area of the sector (A) = 104π/9 square inches

Central angle (θ) = 65 degrees

The formula for the area of a sector of a circle is:

A = (θ/360) * π * r^2

We can rearrange this formula to solve for the radius (r):

r^2 = (A * 360) / (θ * π)

Plugging in the given values:

r^2 = (104π/9 * 360) / (65 * π)

r^2 = (104 * 40) / 9

r^2 = 4160 / 9

r^2 ≈ 462.22

Taking the square root of both sides:

r ≈ √462.22

r ≈ 21.49

Therefore, the radius of the circle is approximately 21.49 inches.

Answer: 8 inches

The solution of the given quadratic equation -5 = -36 / m + m is,

 m = - 9 or  m = 4

The given equation is

-5 = -36 / m + m

After re arranging it we get,

m² + 5m - 36 = 0

This is nothing but quadratic equation,

Since we know that,

The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations. The quadratic equation has the following generic form:

ax² + bx + c = 0

So now we can write,

⇒ m² + 9m - 4m - 36 = 0

⇒ m(m + 9) - 4(m + 9) = 0

⇒ (m + 9)(m - 4) = 0

Therefore,

⇒ (m + 9) = 0 or (m - 4) = 0

⇒ m = - 9 or  m = 4

Thus,

The solution of the given expression is

m = - 9 or  m = 4

To calculate the mean, median, and mode, we first need to know what each of these terms represents. The mean, also known as the average, is the sum of all the values divided by the total number of values. To find the mean, add up all of the values and divide by the number of values. The median is the middle value in a set of data when it is arranged in order from least to greatest. The mode is the value that occurs most frequently in a set of data. Here's an example to illustrate these concepts:

Let's say we have a set of data consisting of the following values: 2, 5, 5, 7, 8, 10, 12. To find the mean, we add up all of the values and divide by the number of values. In this case, the sum of the values is 49 (2+5+5+7+8+10+12) and there are 7 values, so we divide 49 by 7 to get the mean, which is approximately 7. To find the median, we first need to arrange the data in order from least to greatest: 2, 5, 5, 7, 8, 10, 12. The middle value is 7, so that is the median. To find the mode, we look for the value that occurs most frequently. In this case, 5 occurs twice, which is more than any other value, so the mode is 5.
In conclusion, the mean, median, and mode are all measures of central tendency that can be used to describe a set of data. The mean is the average value, the median is the middle value, and the mode is the value that occurs most frequently. When calculating these measures, it is important to carefully consider the data and choose the appropriate method for finding each value.

Step-by-step explanation:

The video had played 104 frames when the time was equal to -3 2/5 seconds.

We can start by finding how many frames were played during the time that the timer did not start counting. Since the video plays 25 frames per second, the number of frames played during this time is 25 frames/second × several seconds = 190 frames.

Next, we need to convert the time of -3 2/5 seconds to frames. We can do this by multiplying the time by the frame rate of 25 frames/second:

-3 2/5 seconds × 25 frames/second = -86 frames

Note that the negative sign indicates that the timer is behind the actual playback time.

Finally, we add the number of frames played before the timer started counting to the number of frames that had played by the time the timer was at -3 2/5 seconds:

190 frames + (-86 frames) = 104 frames

The number of minutes spent higher than 38 meters above the ground on the Ferris wheel ride is approximately 1.0918 minutes.

To solve this problem, we need to determine the angular position of the Ferris wheel when it is 38 meters above the ground.

The Ferris wheel has a diameter of 50 meters, which means its radius is half of that, or 25 meters.

When the Ferris wheel is at its highest point, the radius and the height from the ground are aligned, forming a right triangle.

The height of this right triangle is the sum of the radius (25 meters) and the platform height (4 meters), which equals 29 meters.

To find the angle at which the Ferris wheel is 38 meters above the ground, we can use the inverse sine (arcsine) function.

The formula is:

θ = arcsin(h / r)

where θ is the angle in radians, h is the height above the ground (38 meters), and r is the radius of the Ferris wheel (25 meters).

θ = arcsin(38 / 29) ≈ 1.0918 radians

Now, we know the angle at which the Ferris wheel is 38 meters above the ground.

To calculate the time spent higher than 38 meters, we need to find the fraction of the total revolution that corresponds to this angle.

The Ferris wheel completes one full revolution in 2 minutes, which is equivalent to 2π radians.

Therefore, the fraction of the revolution corresponding to an angle of 1.0918 radians is:

Fraction = θ / (2π) ≈ 1.0918 / (2π)

Finally, we can calculate the time spent higher than 38 meters by multiplying the fraction of the revolution by the total time for one revolution:

Time = Fraction \(\times\) Total time per revolution = (1.0918 / (2π)) \(\times\) 2 minutes

Calculating this expression will give us the answer in minutes.

Answer:

To solve the equation sin 2x = 4cos 2x, we can use the trigonometric identity:

sin 2x = 2sin x cos x

cos 2x = cos^2 x - sin^2 x = 1 - 2sin^2 x

Substituting these identities into the equation, we get:

2sin x cos x = 4(1 - 2sin^2 x)

Expanding and simplifying, we get:

2sin x cos x = 4 - 8sin^2 x

Rearranging, we get:

8sin^2 x + 2sin x cos x - 4 = 0

We can factor the left-hand side of this equation:

(2sin x - 1)(4sin x + 4) = 0

Setting each factor equal to 0 and solving for sin x, we get:

2sin x - 1 = 0 or 4sin x + 4 = 0

sin x = 1/2 or sin x = -1

If sin x = 1/2, then x is a multiple of π/6, so the general solution in this case is:

x = π/6 + 2πn or x = 5π/6 + 2πn

Where n is an integer.

If sin x = -1, then x is a multiple of π plus an odd multiple of π/2, so the general solution in this case is:

x = π/2 + πn

Where n is an integer.

Therefore, the general solution for sin 2x = 4cos 2x is:

x = π/6 + 2πn or x = 5π/6 + 2πn or x = π/2 + πn

Where n is an integer.

Answer:

Justin keeps 3 marbles. Each friend gets 4 marbles.

Step-by-step explanation:

The volume generated by rotating the region about x = 3 is (54π/5).

First, we need to find the intersection points of the two curves:

y = 18 - \(x^2\)

y = \(x^2\)

Setting them equal, we get:

18 - \(x^2\) =\(x^2\)

Solving for x, we get:

x = ±3

So the region bounded by the curves is:

3 ≤ x ≤ -3

0 ≤ y ≤ \(x^2\)

To use the method of cylindrical shells, we will imagine the region being rotated about the line x = 3. This means that the axis of the cylindrical shells will be parallel to the y-axis. A typical shell will have a radius of x - 3 and a height of dy.

The volume of a typical shell can be found using the formula:

dV = 2πr h dy

where r = x - 3 and h = y. The factor of 2π comes from the fact that we are rotating the region around a vertical line.

Substituting in the values for r and h, we get:

dV = 2π(x - 3) y dy

To find the total volume, we need to integrate over the region:

V = ∫(from 0 to 9) 2π(x - 3) y dy dx

The limits of integration for x are from 0 to 3, since the curves are symmetric about the y-axis. The limits of integration for y are from 0 to \(x^2.\)

Performing the integration, we get:

V = ∫(from 0 to 3) ∫(from 0 to \(x^2\)) 2π(x - 3) y dy dx

V = ∫(from 0 to 3) π(x - 3) \(x^4\) dx

V = π ∫(from 0 to 3) (\(x^5 - 3x^4\)) dx

V = π [\((1/6)3^6 - (1/5)3^5\)]

V = (54π/5)

Therefore, the volume generated by rotating the region about x = 3 is (54π/5).

Step-by-step explanation:

Calculation of the Slope of a line

The information provided about the line is that the line passes through the points  (-8, 9) to (-4,6)

Therefore, the first step consists in computing the slope. The formula for the slope is:
\(m=\frac{y_2-y_1}{x_2-x_1}\)

Now, by plugging the corresponding numbers is , we get that the slope is:

\(m=\frac{y_2-y_1}{x_2-x_1}=\frac{6-9}{-4-(-8)} =\frac{6-9}{-4+8} =-\frac{3}{4}\)

So then, we find that the slope is \(m=-\frac{3}{4}\) and that the line passes through the point  \((-8,9)\).

Answer:

the three boxes should be filled with

Step-by-step explanation:

The general equation of the parabola in this problem is

y = a(x-h)^2 + k

vertex is at (-2, -20), => k=-20, h = 2

so the equation is

y = a(x+2)^2 - 20

To have y-intercept = -12, we set x = 0

-12 = a(0+2)^2 - 20

a(2^2) = 8

a = 2

therefore the equation of the parabola is

y = 2 (x+2)^2 -20 = 2x^2 + 8x - 12

the three boxes should be filled with

It has taken me 32 minutes to drive 48 km. If the total length of my journey is 146 km and I maintain the same speed,  then you can estimate that you will be driving for approximately 65.344 minutes longer to complete the remaining 98 km of your journey.

To estimate how much longer you will be driving for, we can use the concept of proportionality. We know that the time taken to drive 48 km is 32 minutes. Let's use this information to find the time it would take to drive 146 km.

We can set up a proportion to find the time:

(time taken for 48 km) / (48 km) = (time taken for 146 km) / (146 km)

Let's solve for the time taken for 146 km:

(time taken for 146 km) = (time taken for 48 km) * (146 km / 48 km)

Substituting the given values:

(time taken for 146 km) = 32 minutes * (146 km / 48 km)

Calculating the value:

(time taken for 146 km) ≈ 32 minutes * 3.042

(time taken for 146 km) ≈ 97.344 minutes

Therefore, it would take approximately 97.344 minutes to drive 146 km at the same speed.

To estimate how much longer you will be driving for, we can subtract the initial time of 32 minutes from the estimated time of 97.344 minutes:

Additional time = 97.344 minutes - 32 minutes

Additional time ≈ 65.344 minutes

The solution is the point (0, 1/6) y = 1/6

Given the equation y = (-3/4)x + 1/6, which represents a linear equation, there is no "system" of equations involved since there is only one equation.

In this case, the equation is in slope-intercept form (y = mx + b),

where m represents the slope (-3/4) and b represents the y-intercept (1/6).

The slope-intercept form allows us to determine various properties of the equation.

Since there is only one equation, the solution to this equation is a single point on the Cartesian plane.

Each pair of x and y values that satisfy the equation represents a solution.

For example, if we choose x = 0, we can substitute it into the equation to find the corresponding y value:

y = (-3/4)(0) + 1/6

y = 1/6

Therefore, the solution is the point (0, 1/6).

In summary, the given equation has a unique solution, represented by a single point on the Cartesian plane.

Any value of x plugged into the equation will yield a corresponding y value, resulting in a unique point that satisfies the equation.
