A golfer hits a golf ball off the ground with an initial vertical velocity of 176 feet per second. How long does it take for the ball to land? Use the formula h = −16t2 + v0t + h0, where h represents the height of the ball in feet, t represents the time in seconds, v0 represents the initial vertical velocity

which of the following sets of data would produce the largest value for an independent-measures t statistic? the two sample means are 10 and 20 with variances of 20 and 25 the two sample means are 10 and 20 with variances of 120 and 125 the two sample means are 10 and 12 with sample variances of 20 and 25 the two sample means are 10 and 12 with variances of 120 and 125

The volume of a sphere is increased by 6%. calculate the corresponding percentage increased in it area.

Quadrilateral abcd in the figure below represents a scaled-down model of a walkway around a historic site. quadrilateral efgh represents the actual walkway. abcd is similar to efgh. what is the total length, in feet of the actual walkway?
