Monica gets on an elevator in a skyscraper. the elevator starts to move at a rate of -20ft/s. after 6 seconds on the elevator, monica is 350 ft from the ground floor building.

1) the rate of the elevator is negative. what does this mean in the situation? what value in the slope-intercept form of an equation does the rate represent?

2) how many feet was monica above the ground when she got on the elevator? show work

3) what value in the slope-intercept form does your answer to part a represent?

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ab=9, and ac=12, find hc.

Lems1. the following data set represents the scores on intelligence quotient(iq) examinations of 40 sixth-grade students at a particular school: 114, 122, 103, 118, 99, 105, 134, 125, 117, 106, 109, 104, 111, 127,133, 111, 117, 103, 120, 98, 100, 130, 141, 119, 128, 106, 109, 115,113, 121, 100, 130, 125, 117, 119, 113, 104, 108, 110, 102(a) present this data set in a frequency histogram.(b) which class interval contains the greatest number of data values? (c) is there a roughly equal number of data in each class interval? (d) does the histogram appear to be approximately symmetric? if so,about which interval is it approximately symmetric?
