For spring cleanups, a landscaper charges a flat fee of $60 plus $20 for each hour of labor. Which equation models the cost in dollars, c, for a cleanup that requires h hours of labor? c = StartFraction h Over 20 EndFraction + 60
c = StartFraction 20 Over h EndFraction + 60
c = 20 h + 60
c = 20 + 60 h

Adriveway is 40 yards long about how many meters long is it

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.

Match each whole number with a rational, exponential expression 3 square root 27^2find the domain and range of the exponential function h(x)=125^x. explain your findings. as x decreases does h increase or decrease? explain. as x increases does h increase or decrease? explain.
