A sporting goods company sold 830 soccer balls in 2014. Since then, they have sold 10 fewer soccer balls each year. Write a linear function for N t( ), the number of soccer balls sold t years since 2014.

Suppose an investment of $3,800 doubles in value every decade, The function (x) = 3, 800 - 2* decades. How much is the investment worth after 2 decades? gives the value of the investment after x a $15,200 $15,200 $152,000 O d $76,000

A college dormitory houses 650 students, all of whom are susceptible to a particular infectious virus. On a particular day, the infectious virus had been contracted by 15 students. 3 days later, 135 students had contracted the virus. The number of infected students grows at a rate that is jointly proportional to the current number of students who have contracted the virus and the difference between the total number of students in the dorm and the number who have contracted the virus. a. Find a function that gives the number of students who have contracted the virus at any time t. Round to 5 decimal places, if necessary. P (t) = b. Find the number of students who have contracted the virus 5 days after its initial outbreak. Round to the nearest student. P (5)

Tom is driving to Seattle. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Tom has 54 miles to his destination after 49 minutes of driving, and he has 33.2 miles to his destination after 75 minutes of driving. How many miles will he have to his destination after 91 minutes of driving?
