The height of a pelican as it swoops down to catch a fish in the lake is modeled by this equation, where x represents the time, in seconds represents the height of the pelican, in feet. Y = x2 – 67 + 8.75 At the same time, a second pelican flies in a straight line, modeled by this equation. Y = q 1 + 5 Which statement describes the number and viability of the system's solutions? A. The system has only one solution, and it is viable because it results in positive values of time. B. The system has only one solution, but it is not viable because it results in a negative value of time. C. The system has two solutions, but only one is viable because the other results in a negative value of time. I negative The system has two solutions, and both are viable because they result in positive values of time. D.

When constructing a perpendicular line through a point off a line, how can you verify that the lines constructed are perpendicular? check the angles used in the construction with a straightedge to ensure consistency. check the distance along the lines at several places with a compass to ensure they are the same length. check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles. check the distance between the lines at several places with a compass to ensure they are equidistant. question 2(multiple choice worth 1 points) (01.03 lc) which of the following steps is included in the construction of a perpendicular line through a point on a line? connect arcs that are above and below the given line with a straightedge. connect arcs that are above the original line with a straightedge. create arcs on either side of a point that is off the given line. create a copied angle by using the first two lines as the original angle.
