2. A cardiac monitor is used to measure the heart rate of a patient after surgery. It compiles the number of heartbeats after t minutes. When the data in the table are graphed, the slope of the
tangent line represents the heart rate inlbeats
per minute.
t (min)
36
38
40
42
44
Heartbeats 2530 2661 2806 2948 3080
The monitor estimates this value by calculating the slope of a secant line. Use the data to estimate
the patient's heart rate after 42 minutes using the secant line between the points with the given
values of t.
a. t = 36 and t = 42
b. t = 38 and t = 42
C. t = 40 and t = 42
d. t = 42 and t = 44
What are your conclusions?

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
