Relationship B has a greater rate than Relationship A. This graph represents Relationship A.
r-ruslan [8.4K]

The second table could represent relationship B.

Step-by-step explanation:

Step 1:

The tables give a relationship between the growth of a plant and the number of weeks it took.

To determine the rate of each table, we determine the growth of the plant in a single week.

The growth rate in a week = \frac{Difference in height}{time taken}.

Step 2:

For the given graph, the points are (4, 3) and (8, 6).

The growth rate in a week = \frac{Difference in height}{time taken} = \frac{6-3}{8-4}=\frac{3}{4}  = 0.75.

So the growth rate for relationship A is 0.75.

Step 3:

Now we calculate the growth rates of the given tables.

Table 1's growth rate in a week = \frac{Difference in height}{time taken} = \frac{3-1.2}{5-2}=\frac{1.8}{3}  = 0.6.

Table 2's growth rate in a week = \frac{Difference in height}{time taken} = \frac{4-1.6}{5-2}=\frac{2.4}{3}  = 0.8.

Table 3's growth rate in a week = \frac{Difference in height}{time taken} = \frac{2-1.5}{4-3}=\frac{0.5}{1}  =0.5.

Table 4's growth rate in a week = \frac{Difference in height}{time taken} = \frac{3.5-1.4}{5-2}=\frac{2.1}{3}  = 0.7.

Since relationship B has a greater rate than A, Table 2 is relationship B.

Answers:

4) r = √[V/(πh)]; d ≈ 5 in

5) 1.25x + 2.50y = 25.00 ; 11 combinations

Step-by-step explanation:

4) (a) Formula for radius

V = πr²h     Divide each side by πh

V/(πh) = r²     Take the square root of each side.

r = √[V/(πh)]

(b) Diameter of tuna can

(i) <em>Data: </em>

V = 66 in³

h = 3.3 in

(ii) <em>Calculations </em>

r = √[V/(πh)]

  = √[66/(π × 3.3)]

  = √(20/π)

  = 2√(5/π)

d = 2r

  = 4√(5/π)

  ≈ 5 in

5) Hot dogs and hamburgers

(a) <em>The equation </em>

Let x = the number of hot dogs

and y = the number of hamburgers

Then

1.25x + 250y + 7 × 0.50 = 28.50

     1.25x + 250y + 3.50 = 28.50     Subtract 3.50 from each side

                1.25x + 2.50y = 25.00

(b) <em>Plot the graph</em>

 Let x = 0. Then

2.50y = 25.00     Divide each side by 2.50

       y = 10

Plot a point at (0, 10).

Let y = 0. Then,

1.25x = 25.00     Divide each side by 1.25

       x = 20

Plot a point at (20, 0).

Draw a straight line between the two points.

Your graph should look like the one below.

(c) <em>Hot dog/hamburger combinations </em>

The possible hot dog/hamburger (x/y) combinations are:

0x + 10y, 2x + 9y, 4x + 8y, 6x + 7y, 8x + 6y, 10x + 5y, 12x + 4y, 14x + 3y, 16x + 2y, 18x + 1y, 20x + 0y

Thus, there are 11 different combinations that Zeke and his friends can buy for $28.50.

It works like this, because one hamburger costs $2,50 and a hamburger half as much.

You can replace one hamburger with two hot dogs (or vice versa) and still spend the  same amount of money,.
