Course 3 • Countdown • 7 Weeks 39
Program: SBAC Component: Count Down 7
PDF-PassVendor: MPS Grade: Course 3
Countdown: 7 Weeks1. Jeremy takes his heart rate (in beats per minute) after running
on the treadmill for different periods of time. Find and describe the constant rate of change for this function. Find and describe the initial value.
rate of change:
initial value:
2. Carrie creates triangular pendants to be worn as necklaces. Two pendants are shown. Select all of the statements that are true about the pendants.
�ABC � �DEF by the SAS Similarity Theorem.
Since there are two corresponding congruent angles, the third angles in the triangles must also be congruent.
m∠E � m∠B and m∠C � m∠F
By the Angle-Angle Similarity, �ABC ∼ �DEF.
The measure of the third angle in each triangle can be found by subtracting the sum of the given angles from 360º.
3. Members of a book club pay lower prices for individual books and a flat shipping rate. One member graphs how much she spends and draws a line of best fit. Write an equation for the line of best fit. What does the slope represent? What does the y-intercept represent?

4. A road divides the neighborhood park into two parts. Calvin plots one part in a coordinate plane. The part of the park shown is a reflection over the x-axis of the other part.
Part A: Draw the other part of the park.
Part B: Write the coordinates of the vertices of the part that you drew. Then describe the effects of a reflection across the x-axis on the coordinates.
5. The choir started selling CDs of their concerts as a fundraiser in 2008. The table shows the number of CDs sold each year.
Part A: Draw a line of best fit.
Part B: Write the equation of the line of best fit. According to the model, how many CDs were sold in 2008? Predict how many CDs will be sold in 2016. Justify your answer.
