5. Mia crosses a river when she drives from her house to the beach. The graph of the function d(t) = 40 lt -1.25 shows Mia's distance from the river d, in
miles, after t hours. The domain of the function is 0 SX 2.5. The graph
shows her entire trip.

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

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)
