Which model best represents the data?
The data in the table represent the height of an object over
time.
Height of an Object
Time (seconds)
Height (feet)
quadratic, because the height of the object increases or
decreases with a multiplicative rate of change
quadratic, because the height increases and then
decreases
exponential, because the height of the object increases
or decreases with a multiplicative rate of change
exponential, because the height increases and then
decreases

answer is 144

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
