Use the fact that every real number has a decimal expansion to produce a 1–1 function that maps s into (0, 1). discuss whether the formulated function is onto. (keep in mind that any terminating decimal expansion such as .235 represents the same real number as .234999 . . )

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

If the scale factor between two circles is 2x/5y what is the ratio of their areas?

The bottom of ignacio's desktop is 74.5cm from the floor. ignacios sits in his adjustable chair, and the tops of his legs are 49.3cm from the floor. each clockwise rotation of the knob on the chair raises ignacio's legs by 4.8cm. write an inequality to determine the number of clockwise rotations, r, ignacio could make with the knob without his legs touching the desk.
