Answer:

Step-by-step explanation:

To plot the point (5, 2 ) on the coordinate plane

The first value is in the positive x- direction, that is 5 units to the right from the origin and the second value is in the positive y- direction, that is 2 units up.

So 5 units right on the x- axis and 2 units up on the y- axis from the origin.

Graph a triangle (ABC) and reflect it over the x-axis to create triangle A'B'C'. Describe the transformation using words. Make s

tatyana61 [14]

Answer:

Part A

We note that the vertices of a triangle are formed by three non colinear points, which are A(3, 3), B(6, 6), C(9, 3)

The image of the reflection of a point (x, y) across the x-axis is (x, -y)

Therefore, the image of the triangle are; A'(3, -3), B'(6, -6), and C'(9, -3)

The characteristics of the transformation includes;

1) The dimensions of the preimage and image triangles are the same (rigid transformation)

2) The image is the representation of the inverted (upside down) of the preimage

3) The x-values of the image and the preimage are the same, while the y values are equal in magnitude but opposite in sign

Part B

Please find attached the drawing of the triangle ΔABC, ΔA'B'C' and the lines from A and and A' to the reflecting line, the x-axis

Based on the above characteristics, the perpendicular line drawn from A to the reflecting line(the x-axis and the line drawn from A' to the x-axis are equal in length and they intersect at the same point on the x-axis

Part C

Given that the x-axis values of B and B' and the magnitudes of the y-axis values of B and B' are the same, we have that the length of the perpendicular lines from B and B' will have equal length and point of intersection on the x-axis

Therefore, the same characteristics is seen when a line segment connecting B with the reflecting x-axis and then a line B' with the reflecting line is drawn

What is the value of s and what is the correct amount of units

Bond [772]

Step-by-step explanation:

Here,

ABCD is rhombus,

AB=9s+29

CD =10s -18

now, AB=CD (opposite side of rhombus is parallel and equal)

or,9s +29=10s-18

or, 10s -9s= 29+18.

The value of s is 47.

Therefore, the measure of AB is 9×47+29.

=452.

Complete question :

The table shows data collected on the relationship between time spent playing video games and time spent with family. The line of best fit for the data is ý = -0.36x + 94.5.

Video Games (Minutes) Time with Family (Minutes)

40 80

55 75

70 69

85 64

A) According to the line of best fit, the predicted number of minutes spent with family for someone who spent 36 minutes playing video games is 81.54.

B) Is it reasonable to use this line of best fit to make the above prediction?

Answer:

81. 54

4) The estimate, a predicted time of 81.54 minutes, is both reliable and reasonable.

Step-by-step explanation:

Given that :

The equation of best fit is defined as :

ý = -0.36x + 94.5.

A.) Predicted number of minutes spent with family (y) for someone who spends 36 minutes playing games (x) will be :

x = 36

From the model :

ý = -0.36(36) + 94.5

y = - 12.96 + 94.5

y = 81.54

Hence.nunber of minutes spent with family = 81.54 minutes.

B.) The correlation Coefficient for the model is - 0.9993, which indicates a very strong negative relationship between both variables. Hence, using this fact, we can conclude that the prediction is reliable. From the data also, spending 36 minutes playing games means such individual will have more time than someone who plays games for 40 minutes, hence, the prediction is also reasonable.
