Answer:
The perimeter is approximately 19.
Step-by-step explanation:
Three of the sides are roughly four segments long and two are around three and a half.
4 + 4 + 4 + 3.5 + 3.5 = 19
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:

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

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

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

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

Therefore, the table that could represent Relationship B is table A.
Answer:The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
Step-by-step explanation:
90 for the first one
120 for the second one
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.
