The map of a biking trail is drawn on a coordinate grid. the trail starts at p(−3, 2) and goes to q(1, 2). it continues from q to r(1, −1) and then to s(8, −1). what is the total length (in units) of the biking trail? 20 points and first right answer gets brainliest and 5 stars                            

This problem can certainly be done using the distance formula. However, you'd find it much faster to graph these 3 points and then read off the vertical and horiz. distances directly from your graph. From P to Q is 4 units; from Q to R is 3 units, and from R to S is 7 units. The total length of the trail is 4+3+7, or 14 (units).

a i think plz give me brainliest

Step-by-step explanation:

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)
