whose graph passes through the points (-1, 0) and (-5, 0)

If the train travels at an average speed of 50 Km/h, it would be late by 10 minutes.

Speed is simply referred to as distance traveled per unit time.

It is expressed as:

Speed = distance / time

Given that the train running between two stations 50 Km apart arrives on time if it travels at an average speed of 60 km/h.

The time taken by the train to travel 50 km at an average speed of 60 km/h can be calculated using the formula:

Speed = distance / time

time = distance / speed

time = 50 km / 60 km/h

time = 5/6 hour

Next, if the train travels at an average speed of 50 km/h, the time taken to cover the same distance of 50 km would be:

Speed = distance / time

time = distance / speed

time = 50 km / 50 km/h

time = 1 hour

Now, the difference in time between the two scenarios would be:

time difference = 1 hour - 5/6 hour

time = 1/6 hour

Convert to minutes

time = 1/6 × 60

time = 10 minutes

Therefore, the train would be late by 10 minutes.

Answer:

  $9.34 per square foot

Step-by-step explanation:

You want the cost per square foot of a 36 foot square building that costs $12,099.

The cost per square foot is found by dividing the cost by the number of square feet. That area is found as the square of the side length:

  A = s²

  A = (36 ft)² = 1296 ft²

Then the cost is ...

  cost per square foot = ($12099)/(1296 ft²) ≈ $9.34/ft²

The cost of the building is about $9.34 per square foot.

The graph of the function f(x) with vertex (1, 2) and another point (0, 2) is shown below.

Consider a function f(x) = 3x² - 6x + 2

We know that the graph of quadratic function is a parabola.

We graph the function f(x)

The graph of function f(x) is shown below.

From the graph of f(x), we can observe that the vertex of parabola is (1, 2)

For x = 0 the value of the function f(x) would be,

f(x) = 3x² - 6x + 2

f(0) = 3(0)² - 6(0) + 2

f(0) = 0 - 0 + 2

f(0) = 2

This means that the y-intercept of f(x) is (0, 2)

USD 438

Step-by-step explanation:If we add 20% to the gross amount of USD 365, the total amount would be:USD 365 + 20% of USD 365 = USD 365 + (0.20 * USD 365) = USD 365 + USD 73 = USD 438

If the gross amount is USD 365, then the net amount after adding 20 percent is USD 438.

Net amount refers to the final total after deductions or additions have been made whereas gross amount refers to the total amount before any deductions or additions have been made.

Us the formula:

Net Amount = Gross Amount + (Gross Amount x Percentage)

Given that,

Gross amount = $365

The given percentage = 20%

We can write 20% = 20/100

So, 20% = 0.2

Now put the values into the formula

Net amount  = 365 + (365 x 0.2)

Net amount  = 365 + 73

Net amount  = 438

It looks like there are five data points in the box plot, representing Juan's total sales during each shift. The third data point is $200, which is the median value. Since there are an odd number of data points, we know that the median is exactly in the middle of the data set. This means that two of the data points are less than $200, and two of the data points are greater than $200.

The last data point is $300, which is the maximum value. So we know that only one of the data points is between $200 and $300. Therefore, the fraction of Juan's shifts that had total sales of $225 or more is 1/5, or 20%.

Answer:

Step-by-step explanation:

The solutions are x = 0 and x = 3π/4, written as 0, 2.35619 (in radians).

We can factor out 6 tan(x) from the left-hand side of the equation:

6 tan(x) (tan(x) + 1) = 0

This equation is satisfied if either 6 tan(x) = 0 or tan(x) + 1 = 0.

If 6 tan(x) = 0, then tan(x) = 0. This occurs when x = 0, π, 2π, etc. However, we need to restrict our attention to the interval [0, 27), so the only solution in this case is x = 0.

If tan(x) + 1 = 0, then tan(x) = -1. This occurs when x = 3π/4 + nπ, where n is an integer. However, we need to restrict our attention to the interval [0, 27), so the only solution in this case is x = 3π/4.

Therefore, the solutions of the equation 6 tan²(x) + 6 tan(x) = 0 in the interval [0, 27) are x = 0 and x = 3π/4, which can be written as the comma-separated list: 0, 2.35619.

The sinusoidal function of the form y = A·sin(k·x) + C that matches the function in the graph is; y = 4·sin((π/5)·x) - 1

A sinusoidal function is a periodic function based on the sine or cosine functions.

The form of the function is y = A·sin(k·x)

The peak and trough of the graph are; (-7.5, 3), (-2.5, -5)

The amplitude of the function is therefore; A = (3 - (-5))/2 = 4

The vertical shift of the function is; C = (3 + (-5))/2 = -1

The period of the graph (Number of input x-values required to complete a cycle) = 2.5 - (-7.5) = 10 = 2·π/k

Therefore; k = 2·π/10 = π/5

The horizontal shift can be found as follows;

When x = 0, y = -1, therefore;

Based on the diagram, we can see that the triangle formed by the line segment with length 8 and the two dashed line segments is a right triangle with a 45° angle. This means that the other two angles of the triangle are also 45° each.

Using the properties of 45°-45°-90° triangles, we know that the length of the hypotenuse is equal to the length of either leg times the square root of 2. Therefore, we have:

x = 8 / sqrt(2) = 8 * sqrt(2) / 2 = 4 * sqrt(2)

So the value of x is option B: 8√2 / 2 or simplified, 4√2.

The partial sum of the sequence {2, 3, 5, 8, 13, ...} for the first 8 terms is 761/2.

The sequence given is a Fibonacci sequence, where each term is the sum of the previous two terms. To find the partial sum for the first 8 terms, we can use the formula for the sum of a finite geometric series:

Sₙ = a(1 - rⁿ)/(1 - r),

where Sₙ is the sum of the first n terms, a is the first term, r is the common ratio, and n is the number of terms.

In this case, a = 2, r = 3/2 (since each term is 1.5 times the previous term), and n = 8. Plugging these values into the formula, we get:

S₈ = 2(1 - (3/2)⁸)/(1 - (3/2))

From the graph, Jerimiah walks along 44 city blocks.

Hence the correct option is (D).

It is given that each unit on the grid represents 1 city block.

From the given graph we can see that

Number of city block between Restaurant and Museum = 7

Number of city blocks between Museum and Hotel = 4

Number of city blocks between Hotel and Arena = 7

Number of city blocks between Arena and Restaurant = 4

Total number of city blocks along the rectangular path = (7 + 4 + 7 + 4) = 22 city blocks.

Jerimiah walks twice around the rectangular path.

Rectangles are quadrilaterals which have two sets of parallel lines. This means that two sets of sides are equal which are the opposite ones. This means that when plotted on a coordinate plane, of the four points, the x - values should repeat twice and the y - values should repeat twice as well.

They would do so by alternating with each other. This means that in a rectangle with (-2, -3), (- 2 . 3, 1 . 6), ( 4 . 6 , 1. 6 ), the fourth vertex would be the two x and y values that are yet to repeat which would be:

Quilt is in the form of a square such that area of square is given by

Therefore, area of quilt =   square inches

Answer:

To solve this expression, we need to follow the order of operations (PEMDAS) which stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

The expression is:

1234 - 4566 / 45.44 + 67 * 755.34

First, we need to perform the division operation since it comes before addition and multiplication.

4566 / 45.44 = 100.50

Now, we can substitute that into the expression:

1234 - 100.50 + 67 * 755.34

Next, we need to perform the multiplication operation:

67 * 755.34 = 50,548.78

Now, we can substitute that into the expression:

1234 - 100.50 + 50,548.78

Next, we can perform the addition and subtraction operations:

1234 + 50,448.28 = 51,682.28

Therefore, the result of the expression is 51,682.28.

Answer:

19π/6 radians and 31π/6 radians

Step-by-step explanation:

To rotate point A counterclockwise by 7π/6 radians, we can add this angle to the angle of point A, which is 0 radians, to get the angle of point B:

The angle of point B = angle of point A + 7π/6 radians

= 0 radians + 7π/6 radians

= 7π/6 radians

Angle of point B in degrees = (7π/6) * (180/π) degrees

= 210 degrees

To find two other positive angles of rotation that take A to B, we can add any multiple of 2π radians to the angle of point B. This is because adding 2π radians is equivalent to a full rotation around the unit circle, which brings us back to the same point. Therefore, we have:

angle of rotation 1 = angle of point B + 2π radians

= 7π/6 radians + 2π radians

= 19π/6 radians

angle of rotation 1 in degrees = (19π/6) * (180/π) degrees

= 285 degrees

angle of rotation 2 = angle of point B + 4π radians

= 7π/6 radians + 4π radians

= 31π/6 radians

angle of rotation 2 in degrees = (31π/6) * (180/π) degrees

= 465 degrees

So the two other positive angles of rotation that take A to B are (19π/6 radians and 31π/6 radians) or 285 degrees and 465 degrees respectively.

Note:

To convert the angles from radians to degrees, we can use the conversion factor:

1 radian = 180/π degrees

To find the polar coordinates of a point given its Cartesian coordinates (x, y), we can use the following formulas:

r = √(x^2 + y^2)

θ = atan2(y, x)

where r is the radial distance from the origin to the point, and θ is the angle measured counterclockwise from the positive x-axis to the line connecting the origin and the point.

Given the Cartesian coordinates (x, y) = (√3, 1), we can plug these values into the formulas to find the polar coordinates:

r = √(√3^2 + 1^2) = √(3 + 1) = 2

θ = atan2(1, √3)

Using a calculator, we can find that θ is approximately 0.5236 radians.

So, the polar coordinates of the point (√3, 1) are (r, θ) = (2, 0.5236 radians).

SA = 48 cm²

Step-by-step explanation:

the surface area (SA) is the sum of the areas of the 5 faces.

1 square and 4 congruent triangles form the pyramid

area of square = 4 × 4 = 16 cm²

area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 4 and h = 4

area = [tex]\frac{1}{2}[/tex] × 4 × 4 = 2 × 4 = 8 cm²

area of 4 triangles = 4 × 8 = 32 cm²

SA = 16 + 32 = 48 cm²

The surface area of the cube of side x-4 in terms of x is 6x² - 48x + 96.

Given length of a side of a cube (a) = x-4

By, substituting the 'a' value in the above formula we can obtain the surface area of the cube.

6a² = 6 * (x-4)²                           [a = x-4]

      = 6 * (x² - 8x + 16)

      = 6x² - 48x + 96
