Good Work! This is Box #3!

Before you begin: Be sure the calculator is set to default mode, as shown at the right. Hit the MODE key and be sure all entries are highlighted on the left. If not, use your arrow keys to move to the left and press ENTER to highlight, as you arrow down the screen. Now, answer the following 5 questions.

Box 3 - Basic Operational Skills: 1. Which numbered choice describes what happens when you press ? 1) 10 is raised to the 5th power. 2) 10 is multiplied by 5. 3) 5 is raised to the 10th power. 4) 10 is multiplied by 5 times 10       2. Which numbered choice represents the keystrokes that will place a on the screen? 1) to 2) 3) 4) Both 1 and 2 yield         3. Using your calculator, find the area of a circle whose radius is 12 inches. Round the answer to the nearest hundredth. Which numbered choice is the answer? 1) 1809.56 2) 452.39 3) 113.10 4) 75.40         4. To find the greatest common divisor (gcd) of 24 and 84, use the calculator syntax gcd(24,84). The gcd function is found under , arrow right to NUM, and arrow down to #9. Which numbered choice shows the correct answer? 1) 2 2) 4 3) 6 4) 12         5. To evaluate an expression, such as x² - 5x + 2, when x = 5, type the expression on the home screen replacing x with 5. Or, store 5 in the variable x using (which creates the arrow on the screen) and then enter the expression in terms of x. Which numbered choice is the answer when 3x³ - 4x² + 5x - 12 is evaluated for x = 8? 1) -36 2) -8 3) 654 4) 1308
