Can someone help me out with 11A and 11B?? Thanks.
10. y =-1 9. y= HA: y= -1 HA: y = 0 VA: X = 0 VA: x = 1 11. The weight P in pounds that a beam can safely carry is inversely proportional to the distance D in feet between the supports of the beam. For a certain type of wooden beam, P = 9200 a. If there are 100 feet between supports, how much weight can it carry? b. What distance between supports is needed to carry 4600 lb?
