Lesson Performance Task
You have been asked to create a pendulum clock for your classroom
The clock will be placed on one wall of the classroom and go the
entire height of the wall. Choose how large you want the face and
hands on your clock to be and provide measurements for the body
of the clock. The pendulum will start halfway between the center of
the clock face and its bottom edge and will initially end 1 foot abov
the floor. Calculate the period of the pendulum using the formula
L=9.78t, where L is the length of the pendulum in inches and t is
the length of the period in seconds.

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

Ascientist studied a population of workers to determine whether verbal praise and/or tangible rewards affect employee productivity. in the study, some workers were offered verbal praise, some were offered tangible rewards (gift cards, presents, and some were offered neither. the productivity of each participant was measured throughout the study by recording the number of daily tasks completed by each employee. which inference might the scientists make based on the given information? a.) the number of daily tasks completed by each employee may influence the dependent variable, which is whether the employee receives verbal praise, tangible rewards, or neither. b.) verbal praise and/or tangible rewards may influence the independent variable, which is the number of daily tasks completed by each employee. c.) verbal praise and/or tangible rewards may influence the dependent variable, which is the number of daily tasks completed by each employee. d.) the dependent variables, which are verbal praise and tangible rewards, may influence the number of daily tasks completed by each employee.

Which of the following expressions cannot be simplified to x – 2?
