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:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
