4. The conditional statement"If mC- 97°, then 2C is obtuse" is true. Which of the following statements must also be true?
1. If ZC is obtuse, then m_C= 97º.
2. IfZC is not obtuse, then mzC979.
3. IF mZC+970, then ZC is not obtuse.

A. 1 and 2 only
B. 2 and 3 only
C. 2 only
D. 3 only

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
