a. What are the coordinates of the initial value?
b. What does the initial value represent in this context?
C. What does the rate of change represent in this context?
d. How long does it take the barrel to empty?​

a. What are the coordinates of the initial value?

Step-by-step explanation:

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
