Therefore, the matching is as follows: Option 1: Not given and Option 2: Not linear and Option 3: Not quadratic and Option -1: Not exponential.

Given the function 10.17[3]+[1+31(-0.1)][2.99] and we are required to find its value.

The options provided are 1, 3, 2, -1.

To find the value of the function, we can substitute the values and simplify the expression as follows:

10.17[3] + [1+ 31(-0.1)][2.99] = 30.51 + (1 + (-3.1))(2.99) = 30.51 + (-9.5) = 21.01

Therefore, the value of the given function is 21.01.

Now, to match the given functions to the options provided:

Option 1: The given function is a constant function. It has the same output for every input. It can be represented in the form f(x) = k. The value of k is not given here. Therefore, we cannot compare this with the given function.

Option 2: The given function is a linear function. It can be represented in the form f(x) = mx + c, where m and c are constants. This function has a constant rate of change. The given function is not a linear function.

Option 3: The given function is a quadratic function. It can be represented in the form f(x) = ax² + bx + c, where a, b, and c are constants. This function has a parabolic shape.

The given function is not a quadratic function.

Option -1: The given function is an exponential function. It can be represented in the form f(x) = ab^x, where a and b are constants. The given function is not an exponential function.

Therefore, the matching is as follows:

Option 1: Not given

Option 2: Not linear

Option 3: Not quadratic

Answer:

no

Step-by-step explanation:

linear means straight line.

The scale factor used for scaling the actual rectangular pool was 4/15 and the length of the scaled rectangle is 9.6 feet.

Suppose the initial measurement of a figure was x units.

And let the figure is scaled and new measurement is of y units.

Since the scaling is done by multiplication of some constant, that constant is called scale factor. Let that constant be 's'.

Then we have:

\(s \times x = y\\s = \dfrac{y}{x}\)

Thus, scale factor is the ratio of the new measurement to the old measurement.

For this case, we're specified that:

Dimensions of the original pool = 24 feet wide by 36 feet long

The scaled rectangle's dimension: 6.4 feet width and L feet length (we assume the length be L units).

So, in scale drawing, 24 feet was converted to 6.4 feet. Let the scale factor be 's', then:

\(6.4 = s \times 24\\\\s = \dfrac{6.4}{24} = \dfrac{4}{15}\)

Thus, since length is also scaled by same factor(as the whole figure is scaled by constant scale factor assumingly), we get:

Scaled length = s times original length

\(L = \dfrac{4}{15} \times 36 = 9.6 \: \rm feet\)

Thus, the scale factor used for scaling the actual rectangular pool was 4/15 and the length of the scaled rectangle is 9.6 feet.

The corresponding points (x, y) for the given parameter values t = -2, -1, 0, 1, 2 are:

(-ln(33), 11), (ln(9), 8), (0, 9), (ln(17), 10), (ln(33), 7).

To find the corresponding points (x, y) for the given parameter values, we substitute the values of t into the given parametric equations:

For t = -2:

x = ln(8(-2)^2 + 1) = ln(33)

y = -2 + 9 = 7

So, the point is (ln(33), 7).

For t = -1:

x = ln(8(-1)^2 + 1) = ln(9)

y = -1 + 9 = 8

So, the point is (ln(9), 8).

For t = 0:

x = ln(8(0)^2 + 1) = ln(1) = 0

y = 0 + 9 = 9

So, the point is (0, 9).

For t = 1:

x = ln(8(1)^2 + 1) = ln(17)

y = 1 + 9 = 10

So, the point is (ln(17), 10).

For t = 2:

x = ln(8(2)^2 + 1) = ln(33)

y = 2 + 9 = 11

So, the point is (-ln(33), 11).

Therefore, the corresponding points (x, y) for the given parameter values t = -2, -1, 0, 1, 2 are:

(-ln(33), 11), (ln(9), 8), (0, 9), (ln(17), 10), (ln(33), 7).

that it is difficult to determine an exact percentage of flights that are expected to meet the 20 minute "time to carousel" as it can vary depending on factors such as airport size, number of passengers, and baggage handling procedures. However, according to the Department of Transportation, the average wait time for baggage retrieval at major airports in the United States is around 30 minutes.

In explanation, the time it takes for baggage to reach the carousel after a flight lands is affected by several factors. These include the size of the airport, the number of passengers on the flight, the efficiency of baggage handlers, and any delays or issues that may occur during the transportation of the luggage from the plane to the carousel.

Step-by-step explanation:

The "d" format specifier is used to denote a signed decimal integer in various programming languages and formatting systems.

When used in format strings or printf-style functions, the "d" specifier indicates that the corresponding argument should be formatted as a signed decimal integer. It allows for the representation of both positive and negative whole numbers, including zero.

For example, in C programming, the printf function can be used with the "%d" format specifier to display a signed decimal integer value. Similarly, in other languages such as Python, the "{:d}" format specifier can be used with the format() function or string interpolation to represent a signed decimal integer.

Using the "d" specifier ensures that the output is formatted as a base-10 representation of a signed integer, taking into account the sign of the number.

The radius of the tires can be determined by using the formula for the circumference of a circle, which is given by \( C = 2\pi r \), where \( C \) is the circumference and \( r \) is the radius.

In this problem, we are given that the car travels \( 3.5 \) miles and the tires make 2000 revolutions. To find the radius of the tires, we need to convert the distance traveled into the circumference of the tires.

Since the circumference of the tires is equal to the distance traveled, we can write:

\( C = 3.5 \) miles

Now, we need to convert the distance from miles to inches because the radius needs to be in inches. We know that 1 mile is equal to 5280 feet, and 1 foot is equal to 12 inches. So, we can use these conversion factors to convert the distance:

\( C = 3.5 \) miles = \( 3.5 \times 5280 \) feet = \( 3.5 \times 5280 \times 12 \) inches

Next, we can divide the circumference by the number of revolutions to find the distance traveled per revolution:

\( \text{Distance per revolution} = \frac{{C}}{{\text{Number of revolutions}}} \)

\( \text{Distance per revolution} = \frac{{3.5 \times 5280 \times 12}}{{2000}} \) inches

Finally, since the distance per revolution is equal to the circumference of the tires, we can use the formula for the circumference to find the radius:

\( \text{Circumference} = 2\pi r \)

\( \frac{{3.5 \times 5280 \times 12}}{{2000}} = 2\pi r \)

Now, we can solve for the radius:

\( r = \frac{{\frac{{3.5 \times 5280 \times 12}}{{2000}}}}{{2\pi}} \) inches

Calculating this expression will give us the radius of the tires in inches.

The price per T-shirt should be at least $15 to achieve a profit of $250.

To calculate the price per T-shirt that will yield a profit of at least $250, we need to consider the cost of production, the desired profit, and the number of shirts to be sold.

Given that the cost to make each T-shirt is $10, and we want to sell 50 shirts, the total cost of production would be 10 * 50 = $500.

Now, let's calculate the minimum revenue needed to achieve a profit of $250. We add the desired profit to the total cost of production: $500 + $250 = $750.

Finally, to determine the price per T-shirt, we divide the total revenue by the number of shirts: $750 ÷ 50 = $15.

Therefore, to make a profit of at least $250, the price per T-shirt should be set at $15.

By selling each T-shirt for $15, the total revenue would be $15 * 50 = $750. From this revenue, we subtract the total production cost of $500 to calculate the profit, which amounts to $750 - $500 = $250. Thus, by charging $15 per T-shirt, the desired profit of $250 is achieved.
