On January 1, 2010, Danville has a population of 50,000 people. Danville then enters a period of population growth of 7% each year. On the same day
Schererville has a population of 70,000 people. Schererville starts to experience a
population decline. Its population decreases by 4% each year.
1. Write an exponential function rule for both.
2. Create a Table and Graph to model the population of both cities for year
2010 to 2020.
3. During what year will the population of Danville first exceed that of
Schererville? Explain.
4. Create a table and graph to model the difference in population for both
cities year 2010 to 2020.
5. Write a Summary for part 4. At least 3 sentences.

You deposit $5000 each year into an account earning 3% interest compounded annually. how much will you have in the account in 30 years?

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
