Suppose you are determining the growth rate of two species of plants. Species A is 25 cm tall and grows 3 cm per month. Species

B is 10 cm tall and grows 8 cm per month. Which system of equations models the height of each species H(d) as a function of days d.
H(d) = 25 + 3d
H(d) = 10 + 8d

H(d) = 2 + 8d
H(d) = 25 + 10d

H(d) = 3 + 25d
H(d) = 8 + 10d

H(d) = 25 + 3d
H(d) = 8 + 10d

Which table of ordered pairs represents a proportional relationship?
grin007 [14]

Answer:

It is the second one

Step-by-step explanation:

A proportional relationship happens when you get the same answer every time that you divide the y by the x.

(2,10) (4,20) (6,30)

10/2 = 5

20/4 = 5

30/6 = 5

That is not true for the other tables.

lakkis [162]

If there were 49 cars in a line that stretched 528 feet, what is the average car length? assume that the cars are lined up bumper-to-bumper

Answer: We are given there are 49 cars

Also these 49 cars are in a line stretched 528 feet.

Now the average length of the car is:

Average length = \frac{(length-covered-by-49-cars)}{Number-of-cars}

                          =\frac{528}{49}=10.78

Therefore, the average length of car is 10.78 feet

Cassidy's diving platform is 6 ft above the water. One of her dives can
avanturin [10]

Answer:

Before coming back up to the surface the maximum depth, Cassidy went was 6.25 ft. below the water surface

Step-by-step explanation:

The height of Cassidy's diving platform above the water = 6 ft.

The equation that models her dive is d = x² - 7·x + 6

Where;

d = Her vertical position or distance from the water surface

x = Here horizontal distance from the platform

At Cassidy's maximum depth, we have;

dd/dx = d(x² - 7·x + 6)/dx = 2·x - 7 = 0

x = 7/2 = 3.5

∴ At Cassidy's maximum depth, x = 3.5 ft.

The maximum depth, d_{max} = d(3.5) = 3.5² - 7 × 3.5 + 6 = -6.25

The maximum depth, Cassidy went before coming back up to the surface = d_{max} = -6.25 ft = 6.25 ft. below the surface of the water.
