The exponential function in the graph shows the mass, in grams, of a radioactive substance as it decays over time, in hours. the linear function in the table represents the increase in a substance’s mass, in grams, over time, in hours. time (h) mass (g) 2 20 3 24 4 28 5 32 how does the y-intercept of the exponential function compare to the y-intercept of the linear function? drag the correct answer to the box to complete the statement. 10 less than10 more than2 more than2 less than the y-intercept of the exponential function is the y-intercept of the linear function.

   The y-intercept of the exponential function is - 2 less than - the y-intercept of the linear function.

     Each time in the table the output has 4 more than the previous output, so just subtract 8 from the from the 20 output to find out that the y-intercept is 12.

    The y-intercept is represented on the graph at the point where y=0 which is 10 by the way.

     10 is 2 less than 12.

2 1/2 feet

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
