Two swimmers jump from12 foot diving boards. On the graph below, Swimmer 1’s distance from the water is modeled by the function ()and swimmer 2’sdistance from the water is modeled by the function (), where represents time, in seconds.

Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2

Rhombus adef is inscribed into a triangle abc so that they share angle a and the vertex e lies on the side bc . what is the length of the side of the rhombus if ab=c, and ac=b.
