For years of 1980 to 1990, the number of mountain owners m ( in millions ) in the US can be approximated by the model m=.377t^2 – 2.265t + 3.962,3 ≤ t ≤ 10 where t = 3 represents 1983.
1. In which year did 2.5 million people own mountain bikes?
2. In what year was the number of mountain bike owners at a minimum?

I’ll really appreciated if it’s was posible to explain how did you got the answer. Thank you

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
