precalculus 第一章 Graphs
這題我來回看了不下十次
看不懂題目要問甚麼
明天要上課了
求向版上高手們求解
A wooden access ramp is being built to reach a platform that sits 30 inches
above the floor. The ramp drops 2 inches for every 25 inch run.
(c )Design requirements stipulate that the maximum run be 30 feet and that
the maximum slope be a drop of 1 inch for each 12 inches of run. Will this
ramp meet the requirements? Explain.
(d)What slopes could be used to obtain the 30 inch rise and still meet design
requirements?
