Step-by-step explanation:

When \(0<a<1\), the parabola horizontally expands, so \(a=0.25\) matches with the rightmost graph.

When \(a>1\), the parabola horizontally shrinks, so \(a=4\) matches with the leftmost graph

Last, but not least, \(a=1\) matches with the middlemost graph since the parabola is not affected.

The length of the rectangle is 7 cm and the width is 5 cm.

The whole distance covered by the rectangle's borders or its sides is known as its perimeter. As we know the rectangle will have 4 sides then the perimeter of the rectangle will be equal to the total of its four sides. And the unit will be in meters, centimeters, inches, feet, etc.        

The formula for the Perimeter of the rectangle is given by

Here we have

The length of a rectangle is 2cm greater than the width of the rectangle

And perimeter of the rectangle = 24 cm

Let x be the width of the rectangle

From the given data,

Length of the rectangle = (x + 2) cm  

As we know Perimeter of rectangle = 2(Length+width)

=> Perimeter of rectangle = 2(x+2 + x) = 2(2x +2)

From the given data,

Perimeter of rectangle =  24cm

=> 2(2x +2) = 24 cm

=> (2x +2) = 12     [ Divided by 2 into both sides ]

=>  2x = 12 - 2

=>  2x = 10

=>   x = 5         [ divided by 2 into both sides ]  

Length of rectangle, (x+2) = 5 + 2 = 7 cm

Therefore,

The length of the rectangle is 7 cm and the width is 5 cm.

The total amount of money earned by Nora salary over the 21 years is approximately $1,848,000.

To find the total amount of money earned by Nora over 21 years, we need to calculate the salary for each year and then sum them up.

In the first year, Nora's salary is $40,000.

In the second year, her salary will be increased by 3%, so it will be:

$40,000 + 3% of $40,000 = $40,000 + $1,200 = $41,200.

In the third year, her salary will again increase by 3%, so it will be:

$41,200 + 3% of $41,200 = $41,200 + $1,236 = $42,436.

We can continue this process for each year, adding 3% of the previous year's salary to calculate the next year's salary.

To calculate the total amount of money earned over the 21 years, we need to sum up the salaries for each year. Here's the calculation:

Total = $40,000 + $41,200 + $42,436 + ... (21 terms)

To simplify the calculation, we can use the formula for the sum of an arithmetic series:

Total = (n/2) * (2a + (n - 1)d)

where:

n = number of terms (21 in this case)

a = first term ($40,000)

d = common difference (3% of the previous year's salary)

Plugging in the values:

Total = (21/2) * [2(40,000) + (21 - 1)(0.03)(40,000)]

Simplifying further:

Total = (21/2) * [80,000 + 20(0.03)(40,000)]

= (21/2) * [80,000 + 2,400(40,000)]

= (21/2) * [80,000 + 96,000]

= (21/2) * 176,000

= 21 * 88,000

= 1,848,000

Therefore, the total amount of money earned by Nora salary over the 21 years is approximately $1,848,000.

The price of the first pastry and the filled donuts are 0.72 and 1.1 dollars respectively.

Bill and Mary Ann went to the viola bakery. Bill bough 3 pastry and 8 filled donuts for 10.96 dollars.  Mary Ann bought 4 of each for 7.28 dollars.

Therefore, the price of each type of pastry can be calculated as follows:

using equation,

let

cost of each pastry = x

cost of each filled donuts = y

Therefore,

3x + 8y = 10.96

4x + 4y = 7.28

Multiply equation(ii) by 2

3x + 8y = 10.96

8x + 8y = 14.56

subtract the equation

5x = 3.6

divide both sides by 5

x = 3.6 / 5

x = 0.72

Let's find y

4y = 7.28  - 4(0.72)

4y = 7.28 - 2.88

4y = 4.4

A world without engines is certainly an appealing idea. Although engines are a vital transportation source that allow us to move around and travel much faster and efficiently, passenger vehicles are a major pollution contributor. they produce large amounts of carbon monoxide, nitrogen oxides, and other forms of pollution. Removing all engines would definitely have downsides, but the significant amount of help it would provide towards lowering pollution rates would be extremely impactful towards our environment and earth. Engines are important parts of human life, and getting things done faster is much more efficient, without engines humans would have to do many things by hand and it would slow production of many things that are necessities. There are also many situations regarding human lives that require the fastest transportation possible, and without engines many things wouldn't get done fast enough. In conclusion, a world without engines would have many benefits towards the environment, however, we've grown to be too dependent on these machines and without them production of many things would start to slow and many trips around the world would be near impossible or extremely delayed.

To find the largest number of passengers in the tram, we need to calculate the maximum number of passengers who can go without a ticket.

Given that 12% of passengers go without a ticket, we can set up the following equation:

12% of x = 60

To solve for x, we can divide both sides of the equation by 0.12:

x = 60 / 0.12

x = 500

Therefore, the largest number of passengers in the tram, if it is not greater than 60, would be 500.

To find the largest number of passengers in the tram, we use the percentage given and set it equal to the number of passengers. By solving for x, we determine that the largest number of passengers in the tram is 500.

The largest number of passengers in the tram, if it is not greater than 60, is 500.

There is only one rectangle that satisfies the conditions of having the given nonadjacent vertices (4, 3) and (-4, -3) with integer coordinates for the other two vertices.

Let's consider the given vertices (4, 3) and (-4, -3) as the diagonal endpoints of the rectangle.

The other two vertices will lie on the perpendicular bisectors of this diagonal. Since we want the other two vertices to have integer coordinates, the midpoint of the diagonal must also have integer coordinates.

The midpoint of the diagonal can be found by taking the average of the x-coordinates and the average of the y-coordinates:

Midpoint: \($\left(\frac{4 + (-4)}{2}, \frac{3 + (-3)}{2}\right) = (0, 0)$\)

So, the midpoint of the diagonal is (0, 0).

Now we need to find the other two vertices that lie on the perpendicular bisectors passing through this midpoint.

The slope of the diagonal line is given by:

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

The slope of the perpendicular bisector is the negative reciprocal of the diagonal slope:

\($m_{\text{perpendicular}} = -\frac{1}{m} = -\frac{4}{3}$\)

Now we can use the midpoint (0, 0) and the slope

\($m_{\text{perpendicular}} = -\frac{4}{3}$\)  to find the equations of the two perpendicular bisectors.

Equation of the first bisector:

\($y - 0 = -\frac{4}{3}(x - 0)$\)

\($y = -\frac{4}{3}x$\)

For the first bisector, let's assume one vertex lies on the line \($y = -\frac{4}{3}x$\) with integer coordinates (a, b).

Now, since (a, b) lies on the bisector, the distance between (a, b) and the midpoint (0, 0) is equal to the distance between (a, b) and (4, 3).

Distance formula:

\($\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$\)

\($\sqrt{(0 - a)^2 + (0 - b)^2} = \sqrt{(4 - a)^2 + (3 - b)^2}$\)

Simplifying the equation, we get:

\($a^2 + b^2 = (4 - a)^2 + (3 - b)^2$\)

Expanding and simplifying further:

\($a^2 + b^2 = a^2 - 8a + 16 + b^2 - 6b + 9$\)

Simplifying again:

\($8a + 6b = 25$\)

Since a and b must be integers, we can analyze the possible values for a and b.

To have integer solutions for a and b, 8a + 6b must be a multiple of 25.

The possible values for 8a + 6b are:

\($0, 25, 50, 75, 100, \dots$\)

To satisfy the condition 8a + 6b = 25, there is only one solution: a = 2 and b = 3.

Therefore, there is only one rectangle that satisfies the given conditions.

Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, the statement which is most likely true for g is that: A. g(-13) = 20.

In Mathematics, a range can be defined as the set of all real numbers that connects with the elements of a domain.

Based on the information provided in this scenario, the domain and range of this function g(x) in interval notation are as follows:

Function g(0) = 2 is false because it was stated that g(0) = -2. Also, g(-4) = -11 is outside the scope of the given range for this function.

Furthermore, function g(7) = -1 is not within the domain for the given function. However, we can logically deduce that g(-13) = 20 is within the domain for the given function and it would produce an output that is within the scope of the given range for this function.

The value of side a and b for the given triangle is 46.68 units and 17.92 units.

A triangle's angles and side lengths are related by the law of sines, a trigonometric identity. It asserts that the ratio of the sine of one angle to the length of the side opposite that angle is constant for all three angles for any triangle with sides a, b, and c and opposing angles a, b, and c:

If a/sin(A) = b/sin(B) = c/sin(C), then

As long as at least one angle and its matching side length are known, this can be used to solve for unknown angles or side lengths in a triangle.

For the given triangle we have:

cos B = a / c

Thus, substituting the values we have:

cos 21 = a / 50

a = 46.68 units.

Now, sin B = b/50

Sin 21 = b / 50

b = 17.92 units.

We want to find the number 4-digit of positive integers n such that removing the thousands digit divides the number by 9.

__

Let the thousands digit be 'd'. Then we want to find the integer solutions to ...

  n -1000d = n/9

  n -n/9 = 1000d . . . . . . add 1000d -n/9

  8n = 9000d . . . . . . . . multiply by 9

  n = 1125d . . . . . . . . . divide by 8

The values of d that will give a suitable 4-digit value of n are 1 through 7.

When d=8, n is 9000. Removing the 9 gives 0, not 1000.

When d=9, n is 10125, not a 4-digit number.

There are 7 4-digit numbers such that removing the thousands digit gives 1/9 of the number.
