A total of 76 groom's guests and 64 bride's guests attended a wedding. The bride's guests used 96 tissues. The groom's guests us
mylen [45]

Answer:

The tissues each bride's guest used is 1.5.

Step-by-step explanation:

We are given that a total of 76 groom's guests and 64 bride's guests attended a wedding. The bride's guests used 96 tissues. The groom's guests used 152 tissues.

We have to find that approximately how many tissues each bride's guest used.

As we know that whenever we have to find the value of 'each item', we have to use division.

Number of bride's guests who attended a wedding = 64

Number of tissues used by the bride's guests = 96

So, the tissues each bride's guest used =  \frac{\text{Total tissues used by bride's guests}}{\text{Total number of bride's guests}}

                                                                    =  \frac{96}{64}

                                                                    =  \frac{3}{2}  =  <u>1.5</u>

Hence, each bride's guest used approximately 1.5 tissues.

Write an equation for a parabola that has a vertex (1, 2) and passes through the point (3, -6).
Alex

Answer:

y= -2x²+4x.

Step-by-step explanation:

the common equation of the parabola is y=ax²+bx+c, where a, b, c - numbers.

1) the coordinates of the vertex are:

x_0=-\frac{b}{2a} \ and \ y_0=\frac{4ac-b^2}{4a}.

2) if according to the condition x₀=1, then b= -2a.

If according to the condition y₀=2, then   2=\frac{4ac-b^2}{4a}=\frac{4ac-4a^2}{4a}=c-a;

it means that c=a+2.

3) if b= -2a; c=a+2 and the point (3;-6) belongs to the given parabola, then it is possible to substitute them into the common equation of the parabola:

-6=3²*a-6a+a+2; ⇔ a= -2.

4) if a= -2, then b=-2a=4, and c=a+2=0.

5) if a=-2, b=4 and c=0, then the required equation of the parabola is:

y= -2x²+4x.

Name the line of reflection used to map each pre-image to its image.<br> Please help
maks197457 [2]

Answer:

Step-by-step explanation:

From the picture attached,

9). When pre-image KLMN is a reflected across x = -2, we get image K'L'M'N'.

    Therefore, line of reflection will be x = -2

10). In this picture line of reflection which passes through origin (0, 0) and slope = 1 will be,

y = x.

11). Since, all the points of image and preimage points are equidistant from x-axis, line of reflection will be x-axis or y = 0.

12). Line passing through midpoint of the line joining BB' will be the line of reflection.

Coordinates of B → (5, 3)

Coordinates of B' → (5, 7)

Coordinates of BB' → (\frac{5+5}{2},\frac{3+7}{2}) → (5, 5)

Therefore, line of reflection will be y = 5.

13). Coordinates of G → (2, 5)

     Coordinates of G' → (-2, 5)

     Midpoint joining the segment GG' → (\frac{2-2}{2},\frac{5+5}{2}) → (0, 5)

     Therefore, line of reflection → x = 0

14). Line of reflection passing through (0, 0) and slope = -1

     y = -x
