Step-by-step explanation:

he distance between two cities is 180 km.

Speed = distance/time

v = s/t from this we can calculate for time  

Time = distance /speed

This distance was covered by a car at a rate of 50 km/h

Time taken by the car to cover this distance of 180km

= 180/50 = 3.6 hours  

This distance was covered by a bus at 45 km/h

Time taken by the bus to cover this distance of 180km

= 180/45 = 4 hours

This distance was covered by a truck at 40 km/h

Time taken by the truck to cover this distance of 180km

= 180/40 = 4.5 hours

This distance was covered by a bicycle at 25 km/h

Time taken by the truck to cover this distance of 180km

= 180/25 = 7.2 hours

Therefore:

speed and time are directly proportional.

Speed, s is inversely proportional to time, t

xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation

Introducing constant of variation, k  

s = k/t  

When s = 25, t = 7.2

25 = k/7.2

k = 7.2× 25 = 180

So

s = 180/k

The possible scales factors of the given dilation transformation are 3/2 and -3/2. Hence, their sum is zero.

A dilation is a transformation that results in an image with the same shape as the original but a different size.

In a dilation transformation, a negative scale factor enlargement will cause the enlargement to appear on the opposite side of the enlargement's center and will be inverted (upside down). The size of the shape will also alter depending on the degree of the enlargement.

The areas are scaled by 9/4

Since, the area of a square is the square of its side, then scale factor is:

Scale factor = ±√(9/4) =  ± 3/2

Hence, the possible values are positive scale factor: 3/2 and negative scale factor = -3/2.

Their sum is: 3/2 + (-3/2) = 0

Step-by-step explanation:

The given parametric curve x=cost, y=et; 0≤t≤π/2, intersects the line y=1 at t=0, and intersects the line x=0 at t=π/2. Therefore, we need to find the area bounded by the curve and the lines y=1 and x=0, between t=0 and t=π/2. We can use the formula for area enclosed by a curve given by A=∫(y.dx) from a to b, where y is the function of x. In this case, we need to express x in terms of y, so we can use x=arccos(y) and substitute it in the formula. The final result is A=e-1/2.

Answer:

x + y = 36 (1)

7x + 4y = 216 (2)

Step-by-step explanation:

Quanrity of Holiday blend = 36 pounds

Cost per pound of the blend = $6.00

Cost of chocolate chips = $7.00 per pound

Cost of pretzels = $4.00 per pound

Let

Pounds of chocolate chips = x

Downsizing refers to the process of reducing the size and workforce of a company to cut costs, increase efficiency, or adapt to changing market conditions. It involves eliminating positions, reducing staff numbers, or even closing down certain business units or branches.

Downsizing can occur for various reasons, such as financial difficulties, mergers and acquisitions, technological advancements, or strategic reorganization. Companies often assess their operational costs and decide to downsize to improve their financial performance.

During the downsizing process, companies may calculate the potential cost savings by considering factors such as salaries, benefits, severance packages, and operational expenses. For example, if a company decides to eliminate 100 positions with an average salary of $50,000 per year, it could result in annual savings of $5 million.

While downsizing can help companies achieve short-term cost reductions, it often has significant implications for the affected employees, including layoffs, reduced morale, and increased workload for remaining staff. It is crucial for organizations to handle the downsizing process with sensitivity and transparency, providing support to affected employees and communicating the rationale behind the decisions.

It is important to note that downsizing should not be seen as a long-term solution, but rather as a strategic measure to address specific challenges. Companies should also explore alternatives to downsizing, such as retraining and redeploying employees, implementing productivity improvements, or seeking new business opportunities, to ensure sustainable growth and success in the long run.

Substitute the values of a and b into the standard equation: (y^2 / 12^2) - (x^2 / 9^2) = 1, (y^2 / 144) - (x^2 / 81) = 1, This is the equation of the hyperbola with the given properties.

To write the equation of a hyperbola with the given properties, we can use the standard form equation: ((y-k)^2 / a^2) - ((x-h)^2 / b^2) = 1
where (h,k) is the center of the hyperbola, a is the distance from the center to a vertex, and b is the distance from the center to a co-vertex.
First, we know that the y-intercepts are (0, +-12), so the distance from the center to the vertices must be 12. We also know that the foci are (0, +-15), so the distance from the center to the foci must be 15.
Using these values, we can solve for a and b:
c^2 = a^2 + b^2
15^2 = 12^2 + b^2
b^2 = 225 - 144
b^2 = 81
b = 9
Now we know that a = 12 and b = 9. The center of the hyperbola is (0,0) since the y-intercepts are on the y-axis. We can plug these values into the standard form equation to get: (y^2 / 12^2) - (x^2 / 9^2) = 1
Simplifying, we get: (y^2 / 144) - (x^2 / 81) = 1
So the equation of the hyperbola with the given properties is:
(y^2 / 144) - (x^2 / 81) = 1
