Points on a Polar Plane
100

True or False: Points in the 2D plane are identified by the x-value first then the y-value

True

100

True or False: Points in the 3D plane are identified by the x-value first, then the z-value, then the x-value

False

100

True or False: PEMDAS is applied from right to left

False

100

Calculate the percent increase from 10 to 11

(11-10)/11

= 1/10 = 0.1

= 10% increase

100

True or False: The polar coordinate plane is made up of the polar axis and concentric rings about the origin

True

200

Name the point located 2 units right and 5 units up of the origin.

(2, 5)

200

Name the point located 3 units forward, 2 units right and 5 units up from the origin

(3, 2, 5)

200

What is the first step in the order of operations?

Complete the operations within parentheses or grouping symbols (i.e. brackets)

200

Calculate the percent increase from 25 to 50

(50-25)/50

= 25/50 = 1/2

= 50% increase

200

Name the point located 4 units from the origin and rotated 30 degrees

(4, 30o)

300

Name the point located 4 units right and 3 units down from the origin.

(4, -3)

300

Name the point 4 units forward, 3 units left and 1 unit up from the origin

(4, -3, 1)

300

What do the letters in PEMDAS stand for?

Parentheses/Grouping Symbols

Exponents

Multiplication/Division

Addition/Subtraction

300

Calculate the percent decrease from 12 to 9

(12-9)/12

= 3/12 = 1/4

= 25% decrease

300

Name the point located 2 units from the origin and rotated 90 degrees

(2, 90o)

400

Name the point located 1 unit left and 3 units up from the origin.

(-1, 3)

400

Name the point 2 units backward, 4 units right and 1 unit up from the origin

(-2, 4, 1)

400

What operations are grouped in the order of operations?

Multiplication/Division

Addition/Subtraction

400

Calculate the percent decrease from 60 to 48

(60-48)/60

= 12/60 = 1/5

= 20% decrease

400

Name the point located 5 units from the origin and rotated 150 degrees

(5, 150o)

500

Name the point located 4 units left and 7 units down from the origin.

(-4, -7)

500

Name the point 6 units backward, 2 units left and 3 units down from the origin

(-6, -2, -3)

500

What is the first step in simplifying the expression: 4+7(3+3)-1

Add the numbers in the parentheses

500

Calculate the percent decrease from 30 to 21

(30-21)/30

= 9/30 = 3/10

= 30% decrease

500

Name the point located 10 units from the origin and rotated COUNTERCLOCKWISE 60 degrees

(10, 300o)

Hint: 360o - 60o = 300o
