help ma pleaseWhat are the steps for using a compass and straightedge to construct a line through point A that is parallel to line j?A horizontal line j and a point A are drawn. The point A is below the horizontal line j.Drag the steps and drop them in order from start to finish.Place the point of the compass on point Q and open it to width QR .Use the straightedge to draw a line k that passes through A and intersects line j. Label the point of intersection as point P.Use the straightedge to draw AB←→.Without changing the width of the compass opening, place the point of the compass on point A and draw an arc that intersects line k. Label the intersection as point S.With the compass opening set to width QR , place the point of the compass on point S and draw an arc that intersects the arc that was drawn from point A. Label the intersection of the arcs as point B.Place the point of the compass on point P and draw an arc that intersects lines j and k. Label the intersections as points Q and R.

Insect larvae grow incredibly quickly over the first several days of their lives. The length of one particular species increases exponentially at a rate of 25% each day. A scientist studying this species of larva measures one specimen to be 3 mm in length at the beginning of his observation period. The scientist will transfer the larvae to a new environment once the larvae are over 9.16 mm long. If t represents the number of days since the scientist began his observations, write an inequality to represent the situation, and use it to determine after how many days the larvae are transferred to the new environment.
