In 2004, there were about 73.9 million pet dogs in the U. S. In 2017, there were about 89.7 million pet dogs in the U. S. Write a linear equation to represent the number of pet dogs d, in millions, t years after 2000. Round to the nearest hundredth. Please help I'm not smart at all

5

step-by-step explanation:

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
