A theme park ride is descending on a parabolic path that can be approximated by the equation y= -1/80x^2 + 69 (distance is measured in feet). if the horizontal component of its velocity is a constant 6ft/s, find the rate of change of its elevation when x=60

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.

Find the coordinates of point x that lies along the directed line segment from y(-8, 8) to t(-15, -13) and partitions the segment in the ratio of 5: 2.
