Abicycle tire is pumped to a pressure of 120 psi (pounds per square inch). while riding his bike, daniel ran over a small nail, and the tire has a small hole in it. air is leaking and the tire is losing pressure at a rate of 12 psi per minute. if you graphed the pressure of the tire as the output, compared to the number of minutes as the input, which of the following statements about the graph would not be true? a. the graph would be a line. b. the graph would rise from left to right. c. the graph would be only in the first quadrant. d. the more time has passed, the lower the psi would be.

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

You can find the constant of proportionality by finding the ratio of

In new york city at the spring equinox there are 12 hours 8 minutes of daylight. the longest and shortest days of the year very by two hours and 53 minutes from the equinox in this year the equinox falls on march 21 in this task you use trigonometric function to model the hours of daylight hours on certain days of the year in new york city a.what is the independent and dependent variables? b.find the amplitude and the period of the function. c.create a trigonometric function that describes the hours of sunlight for each day of the year. d. graph the function you build in part c. e. use the function you build in part c to find out how many fewer daylight hours february 10 will have than march 21. you may look at the calendar.
