LANDSCAPING A landscaping company has crews who rake leaves and mulch. The company
schedules 2 hours for mulching jobs and 4 hours
for raking jobs. Each crew is scheduled for no
more than 2 raking jobs per day. Each crew's
schedule is set up for a maximum of 8 hours per
day. On the average, the charge for raking a lawn
is $50 and the charge for mulching is $30.
What is a combination of raking leaves and mulching that will maximize the income the company receives per day from one
of its crews?

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
