- Leaf blower the intensity of the sound from a certain leaf blower is measured at 3.2102W/m2 .find the describe 1level .arrow_forwardVital Statistics Let bt be the number of births in the United States in year t, and let dt represent the number of deaths in the United States in year t, where t=10 corresponds to 2010. (a) If pt is the population of the United States in year t, find the function ct that represents the percent change in the population of the United States. (b) Interpret c16.arrow_forwardGrade Point Average In many universities students are given grade points for each credit unit according to the following scale: A 4 points B 3 points C 2 points D 1 point F 0 point For example, a grade of A in a 3-unit course earns 43=12 grade points and a grade of B in a 5-unit course earns 35=15 grade points. A students grade point average GPA for these two courses is the total number of grade points earned divided by the number of units; in this case the GPA is (12+15)8=3.375. a Find a formula for the GPA of a student who earns a grade of A in a units of course work, B in b units, C in c units, D in d units and F in f units. b Find the GPA of a student who has earned a grade of A in two 3-unit courses, B in one 4-unit courses and C in three 3-unit courses.arrow_forward
