A glider begins its flight $1\frac{1}{2}$1 1
2 mile above the ground. After 60 minutes, it is 9 tenths$\frac{9}{10}$

10 mile above the ground. Find the change in height of the glider. If it continues to descend at this rate, how long does the entire descent last?

Aparallelogram has two side lengths of 5 units. three of its sides have equations y = 0, y = 2, y = 2x. find the equation of the fourth side.

State whether weight is a function of height for the six students and explain. a. yes, height is a function of weight because two students weigh 165 pounds but have different heights. b. no, height is not a function of weight because two students weigh 165 pounds but have different heights. c. yes, weight is a function of height because for each value of height there is one corresponding value of weight. d. no, weight is not a function of height because there is not enough data to determine a function.
