Answer:

3rd choice

a rotation of 90° counterclockwise about the origin and a translation down 1 unit

Step-by-step explanation:

This is just asking you what operations you need to perform to get figure N from figure M. Such a set of operations is called a transformation.

In this case we see that to get figure N we have to rotate figure M 90° in a counterclockwise direction. That would be the first transformation

From the choices you can eliminate the first two choices which deal only with clockwise rotation

Translation transformation is one where the figure is shifted horizontally or vertically

All we have to do is figure out if, after 90° counterclockwise rotation of M whether it was shifted 1 unit up or 1 unit down

Look at the point (-3, 1) in figure M.

When a figure is rotated 90° counterclockwise, each if its original coordinates (x, y) become new coordinates (-y, x)

In other words the coordinates are interchanged in the transformed figure and the sign of the new x-coordinate is changed from the original y value

So (-3, 1) should become (-1, -3)

But in figure N, that point has become (-1, -4) which is (-1, -3-1). This indicates the figure has been shifted down which corresponds to a translation down by 1 unit

Answer: 3rd choice

a rotation of 90° counterclockwise about the origin and a translation down 1 unit

The two images I have attached may help you understand better. First one is just the rotation of M. Second one is the rotated figure shifted down which results in figure N

The probability of the 6th order being the order with the free appetizer is 0.0417 (approx).

The probability of an event occurring is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out. The outcome of an event may be known to us or unknown to us. When this happens, we say that there is a chance that the event will happen or not. In general, probability has many wonderful uses in games, in business to make forecasts based on likelihood, and in this emerging branch of artificial intelligence.

The probability of getting a free appetizer is 1/18.

The probability of not getting a free appetizer is 17/18.

If the restaurant gives away an appetizer on the 6th order, then there must have been 5 orders before the 6th one that had no free appetizer, followed by the one with the free appetizer.

[tex]P (X = 6) = P(N N N N N F)[/tex]

= 17/18 x 17/18 x 17/18 x 17/18 x 17/18 x 1/18

The minimum number of hours you will have cruise control on is 1.83 hour(s) and the maximum is 2.83 hour(s).

To find the minimum and maximum numbers of hours you will have cruise control on, you need to calculate the distance you will travel with cruise control on and divide it by your speed.

The minimum distance you will travel with cruise control on is

140 miles - 30 miles = 110 miles.

The maximum distance you will travel with cruise control on is

140 miles + 30 miles = 170 miles.

To convert these distances into hours, you will divide them by your speed of 60 miles per hour.

Minimum hours: 110 miles / 60 mph = 1.83 hours

Maximum hours: 170 miles / 60 mph = 2.83 hours

Eleri wants to be fit for the adventure holiday and to achieve that she runs 2 laps of a running track. Each lap is 400m and she thinks she has run 1km in total. To determine if Eleri is correct, we must first understand the basic units of measurement for distance and how they relate to one another.

A lap of a running track is a distance of 400m. The prefix "kilo" in the unit "kilometer" represents 1000. Therefore, a kilometer is equal to 1000 meters. To convert meters to kilometers, we divide the number of meters by 1000. To convert kilometers to meters, we multiply the number of kilometers by 1000.

To determine the total distance Eleri ran, we must multiply the number of laps by the distance of each lap. 2 laps x 400m per lap = 800m. This is the total distance Eleri ran in meters.

To determine if Eleri ran 1km, we must convert 800m to kilometers. Therefore, to convert meters to kilometers, we divide 800 by 1000. 800m / 1000 = 0.8km.

Therefore, Eleri did not run 1km, she ran 0.8km.

To further demonstrate the accuracy of our calculation, we can use dimensional analysis by using the conversion factor of 1000m = 1km.

800m / (1000m/1km) = 0.8km

This confirms that Eleri ran 0.8km, not 1km.

In conclusion, Eleri is not correct in her assumption that she ran 1km. She actually ran 0.8km which is 800 meters. This was determined by understanding the basic units of measurement for distance, converting the distance from meters to kilometers, and using dimensional analysis to verify our calculations.

Answer:

Step-by-step explanation:

no she is not correct she only ran 0.8 km

The exponential function y = 0.5(34)t has the form y = a*b^t, where a is the initial amount and b is the rate of decay. In this case, a = 0.5 and b = 34.

To find the rate of decay as a percent, we need to find the decimal form of b and then convert it to a percent. To find the decimal form, we need to take the square root of b = 34.

√34 = 5.83

To convert this decimal to a percent, we need to multiply it by 100.

5.83 * 100 = 583%

Therefore, the rate of decay is 583%.

Now we can use these values to evaluate the function when t = 3.

y = 0.5(34)^3

y = 0.5(363)

y = 181.5

So when t = 3, the value of y is 181.5, rounded to the nearest tenth.

Note that the initial amount a = 0.5, the rate of decay r = 583% and the function at t = 3 is 181.5.

There are 5 integer values of M that satisfy the given inequality.

An integer is a whole number, which means it is a number that can be written without a fractional or decimal component. Integers include positive numbers (e.g. 1, 2, 3), negative numbers (e.g. -1, -2, -3), and zero.

They are also often represented using the symbol "Z". Integers are a subset of the set of real numbers.

If M/20 is strictly between 1/3 and 3/5, then we have the following inequalities:

1/3 < M/20 < 3/5

To solve this, we can multiply both sides of the inequality by 20 to get rid of the denominator on the left side:

6 < M < 12

This tells us that M is an integer that lies strictly between 6 and 12 (i.e., 6 < M < 12), and the integers between 6 and 12 are 7, 8, 9, 10, and 11. Therefore there are 5 integer values of M that satisfy the inequality.

The function is decreasing in the interval (-∞,-3/2) and (3/2, ∞) and increasing in the interval (-3/2, 3/2).

What is a function?

A function is a mathematical relation between a set of inputs (often called independent variables, or the domain) and a set of outputs (often called dependent variables, or the range). A function assigns exactly one output for each input. It can be represented by an equation, such as y = f(x), where x is the input and y is the output.

To find the interval(s) in which the function is increasing and decreasing, we can first find the critical points of the function by setting the derivative equal to 0 and solving for x.

The derivative of y = |2x² + x - 6| is not a defined function, it is not differentiable, it is a piece-wise defined function, it has a break at x = -3/2

Hence, the function is decreasing in the interval (-∞,-3/2) and (3/2, ∞) and increasing in the interval (-3/2, 3/2).

Use the concept of prism defined as:

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat sides, and identical bases.

Without bases, the prism's faces are parallelograms or rectangles. And any n-sided polygon, whether a triangle, square, rectangle, or other, might serve as the prism's basis.

Given that,

The dimension of the rectangular prism = 2yd x 10yd x 5yd

Since we know that,

Dimension of prism = length x breadth x height

length x breadth x height =  2yd x 10yd x 5yd

Therefore,

Length = 2 yd

Breadth = 10 yd

Height = 5 yd

Now if dimension doubled the,

The dimension of the new prism = 4yd x 20yd x 10yd

Then,

Length 'l' = 4 yd

Breadth 'b'= 20 yd

Height 'h' = 10 yd

Since we know that,

The surface area of a rectangular prism is,

A=2(bl+hl+hb)

Substitute the values,

A = 2(20x4 +10x4 + 10x20)

A = 640 square units.

Answer: The average rate of change over the interval 12 < x < 30 is -4/3

Step-by-step explanation:

The average rate of change over an interval is defined as the change in the output (f(x)) divided by the change in the input (x) over that interval. In this case, the interval is 12 < x < 30. To find the average rate of change, we need to evaluate the function at the endpoints of the interval and subtract the value at the start point from the value at the end point, and divide that by the change in x.

Given the table:

f(30) = 16 and f(12) = 40

The average rate of change over the interval 12 < x < 30 is:

(f(30) - f(12)) / (30 - 12) = (16 - 40) / 18 = -24/18 = -4/3

So the average rate of change over the interval 12 < x < 30 is -4/3

It's worth noting that this is only the average rate of change, and the function may have different rates of change at different points within the interval 12 < x < 30.

Answer:

y = x + 11

Step-by-step explanation:

the equation of a straight line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, 14 ) and (x₂, y₂ ) = (9, 20 )

m = [tex]\frac{20-14}{9-3}[/tex] = [tex]\frac{6}{6}[/tex] = 1 , then

y = x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (3, 14 )

14 = 3 + c ⇒ c = 14 - 3 = 11

y = x + 11 ← equation of line

A line passes through points (3,14) and (9,20), linear function rule in terms of x and y for this line is y = x + 11

A linear function in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula: m = (y2 - y1) / (x2 - x1). Plugging in the point values from the problem, we get:m = (20 - 14) / (9 - 3) = 6/6 = 1

The y-intercept  be found by plugging in any one of the point values and the slope into the equation y = mx + b and solving for b. Using the point (3,14), we get:

14 = 1*3 + b

b = 11So the linear function in terms of x and y is:

y = x + 11

A linear function is a type of mathematical function that, when graphed, defines a straight line. It is defined by the equation y = mx + b, where x and y are variables, m is the line's slope, and b is the y-intercept (the point where the line crosses the y-axis). The slope (m) of the line represents its steepness, and the y-intercept (b) represents the point at which the line intersects the y-axis.
