Question 1202850: In 2010, the estimated population of Pottsville, USA was 31,713 people. By 2011, the population had grown to 32,928 people.
Assuming that the growth is linear, construct a linear function
that expresses the population of Pottsville
years since 2010 and use it to predict the population in the year 2015.
L(t)=
Round to the nearest thousandth as needed.
If this growth rate continues, the population in the year 2015 will be approximately
people.
Round your answer to the nearest person.
Assuming that the growth is exponential, construct an exponential function
that expresses the population of Pottsville
years since 2010 and use it to predict the population in the year 2015.
Round to the nearest thousandth as needed.
If this growth rate continues, the population in the year 2015 will be approximately
people.
E(t)=
Round your answer to the nearest person.

Question 1203119: Jordan signed up for the Annual Cross Florida bike ride which is a 170 mile bike
ride. After weeks of training he rides at an average of 15 miles per hour. Choose an equation that can be used to show Jordan’s progress in miles (mm) after a number of hours (h).
15h + m = 170
h + 15m = 170
15h = m
h = 15m

Question 1203616: The perimeter of a rectangular room is 60.5 feet. Let x be the width of
the room (in feet) and let y be the length of the room (in feet). Select
the equation that could model this situation.
Ⓐ y = - 2x + 60.5
Ⓑ y = - x + 30.25
Ⓒ 2x + y = 30.25
Ⓓ x + 2y = 60.5
