Assuming the dilation is centered at the origin, it is known that for a dilation of scale factor [tex]k[/tex] centered at the origin, [tex](x,y) \to (kx,ky)[/tex].

The coordinates of the vertices for the figure after the given transformation Dilation of 0.25. is solved to be

I' (-0.5, 0.25)

J' (-1, 1)

K' (1, -0.25)

Dilation is a method of transformation that magnify or shrink the preimage depending on the scale factor

The transformation rule for dilation is as follows

(x, y) for a scale factor of r → (rx, ry)

In the given problem the coordinates of the image is solved when r = 0.25

The measure of the sixth angle of the given convex hexagon is 54 degrees.

We know that the sum of all the interior angles of a convex hexagon is:

720 degrees

Given that three interior angles of the given hexagon measure 140 degrees each.

The fourth angle is 84 degrees.

Let us consider the sixth angle to be x degrees.

Then as per the question, the fifth angle is 3 x (sixth angle) = 3x

Hence, sum of all the angles of the given convex hexagon is:

Using the slope and y - intercept, the linear function that models this problem is y = -33.333x + 68.32

A system of linear equation is a set of at least two linear equations containing the same set of variables. Linear equations use only polynomial coefficients and the operations of addition, subtraction, multiplication and division. The solutions to a linear equation system are the values of the variables which make all the equations true.

To solve this problem, we have to define our variables and set our system of linear equations.

Let;

Using the data given, we can find the slope and y - intercept of a linear function that represents this.

slope (m) = y₂ - y₁ / x₂ - x₁

m = 64.99 - 59.99 / 0.10 - 0.25

m = -33.333

Using the slope in the slope-intercept form of a linear equation

y = mx + c

Taking one point;

59.99 = -33.333(0.25) + c

c = 68.32

The linear equation can be written as;

The scale of a map is a way of expressing the relationship between the distances on the map and the actual distances in the world. If the scale on a map is 1 inch to 20 miles then it means that 1 inch on the map represents 20 miles in the real world.

The median age of the presidents at their death is 69.

The median is the value that is exactly in the middle of a dataset when it is arranged in order. It is a measure of central tendency which separates the lowest 50% from the highest 50% of values.

The median formula is {(n + 1) / 2}th, where “n” is the number of items in the set and “th” means the (n)th number. To find the median, first arrange the data points from smallest to largest.

The steps for finding the median differ depending on whether we have an odd or an even number of data points. If the number of data points is odd, the median is the middle data point in the list. If the number of data points is even, the median is the average of the two middle data points in the list.

In this case, the number of data points is even, that is 38. So, the median is:

= {(n + 1) / 2}th

= {(38 + 1) / 2}th

= 19,5th

Thus, it means the median is the average of the 19th and 20th in the data points. So, it will be:

Median = (68 + 70) / 2

Median = 138 / 2

Median = 69

Answer:

Let x be the cost of the phone.

we know that the cost of the phone case is 10 times cheaper than the phone so the cost of the case is x/10

We also know that the total cost of the phone and the case is 660.

so we can write an equation:

x + (x/10) = 660

We can solve this equation for x by multiplying both sides by 10:

10x + x = 6600

11x = 6600

x = 600

So the cost of the phone is 600 and the cost of the phone case is 600/10 = 60

The response to claim A and Claim B on potential energy being stored in  a magnet in terms of the given options is that;

Claim A; I think So

Claim B; Definitely Not

Claim A; This claim is true because If we move a magnet against the magnetic force of a stronger magnet, the motion will make the magnetic field lines to be compressed and this would lead to an increase in potential energy since the magnetic force lines will now be compressed.

Thus, the claim is correct that there is more potential energy that can be stored by moving against the magnetic force of a stronger magnet.

Claim B; Unlike claim A where the magnets were being moved from each other, in this case they are moved closer to each other and therefore this causes a greater compression of space which will lead to a loss in potential energy. Therefore this claim is not true.
