Answer:

x=17.5 or 18,y=12.5,or 13

Step-by-step explanation:

Relationship B has a lesser rate than Relationship A. The graph represents Relationship A.
Zinaida [17]
Given that Relationship B has a lesser rate than Relationship A and that the graph representing Relationship A is a f<span><span>irst-quadrant graph showing a ray from the origin through the points (2, 3) and (4, 6) where the horizontal axis label is Time in weeks and the vertical axis label is Plant growth in inches.</span>

The rate of relationship A is given by the slope of the graph as follows:

slope= \frac{6-3}{4-2} = \frac{3}{2} =1.5

To obtain which table could represent Relationship B, we check the slopes of the tables and see which has a lesser slope.

For table A.
Time (weeks) 3 6 8 10
Plant growth (in.) 2.25 4.5 6 7.5

slope= \frac{4.5-2.25}{6-3} = \frac{2.25}{3} =0.75

For table B.
Time (weeks) 3 6 8 10
Plant growth (in.) 4.8 9.6 12.8 16

</span><span><span>slope= \frac{9.6-4.8}{6-3} = \frac{4.8}{3} =1.6

</span> For tabe C.
Time (weeks) 3 4 6 9
Plant growth (in.) 5.4 7.2 10.8 16.2

</span><span>slope= \frac{7.2-5.4}{4-3} = \frac{1.8}{1} =1.8

For table D.
Time (weeks) 3 4 6 9
Plant growth (in.) 6.3 8.4 12.6 18.9</span>

<span>slope= \frac{8.4-6.3}{4-3} = \frac{2.1}{1} =2.1</span>

Therefore, the table that could represent Relationship B is table A.

The distance a body falls from rest varies directly as the square of the time the body is falling. If a body falls 81 ft. in 3 s
svetlana [45]
Let the distance = D
Let the time taken = T
From the question, we are told that distance is directly proportional to the square of the time the body takes to fall,
that is, D = K *[T^2]
K is a constant and we have to find its value;
Using the value given in the question;
D = 81 feet
T = 3 seconds
From our original equation,
K = D/ [T^2] = 81/3^2 = 81/9 = 9.
Therefore, K = 9
To find the distance through which the body fall in 7 seconds, we have,
K = 9
T = 7 seconds
D = K * [T^2] 
D = 9 * [7*2] = 9 * 49 = 441.
Therefore, the body will fall through a distance of 441 feet in 7 seconds.
