It is given that and are right angles, and . since they contain right angles, δabr and δacr are right triangles. the right triangles share hypotenuse , and reflexive property justifies that . since and , the transitive property justifies . now, the hypotenuse and leg of right δabr is congruent to the hypotenuse and the leg of right δacr, so by the hl congruence postulate. therefore, by cpctc, and bisects by the definition of bisector.

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

Graph red beads cost $1 an ounce and gold beads cost $3 an ounce. juanita wants to purchase a 12-ounce mixture of red and gold beads that she can sell for $2 an ounce. the solution of the system shows the number of beads needed for juanita to break even. x + y = 12, x + 3y = 24 how many ounces of red beads will juanita buy to break even? how many ounces of gold beads will she buy?
