Mrrafil [7]

Answer:

(-5.4,3) is in the IInd quadrant, (3,-5.4) is in the IVth quadrant.

Mirror image of (-5.4,3)

Step-by-step explanation:

(a) The points are (-5.4,3) and (3,-5.4).

The origin is the center point of the graph. The right side of the x axis is positive the left side is negative. The upward direction from the origin is the positive y axis and the downward direction is negative y axis.

For (-5.4,3) the x axis location is -5.4 and the y axis location is 3

For (3,-5.4) the x axis location is 3 and the y axis location is -5.4

So, the point (-5.4,3) is in the IInd quadrant and the point (3,-5.4) is in the IVth quadrant.

(b) A mirror image with respect to y axis is the point on the opposite side of the quadrant where the point on x axis has changed the sign and y axis point remains constant.

The point (5.4,3) is the mirror image of the point (-5.4,3) with respect to y axis.

The point (3,-5.4) has the x and y points interchanged and the sign of the point on the y axis has changed when comparing to (5.4,3).

In how many ways can the first 4 guests arrive at a party if 15 guests have been invited.

notsponge [240]

Answer:

The first 4 guests can arrive in 32,760 ways.

Step-by-step explanation:

The order in which the guests arrive is important. For example, A,B,C,D is a different outcome to B,A,C,D. So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this question:

4 guests from a set of 15. So

$P_{(15,4)} = \frac{15!}{(15-4)!} = 32760$

The first 4 guests can arrive in 32,760 ways.
