True or False: Points in the 2D plane are identified by the x-value first then the y-value
True
True or False: Points in the 3D plane are identified by the x-value first, then the z-value, then the x-value
False
True or False: PEMDAS is applied from right to left
False
Calculate the percent increase from 10 to 11
(11-10)/11
= 1/10 = 0.1
= 10% increase
True or False: The polar coordinate plane is made up of the polar axis and concentric rings about the origin
True
Name the point located 2 units right and 5 units up of the origin.
(2, 5)
Name the point located 3 units forward, 2 units right and 5 units up from the origin
(3, 2, 5)
What is the first step in the order of operations?
Complete the operations within parentheses or grouping symbols (i.e. brackets)
Calculate the percent increase from 25 to 50
(50-25)/50
= 25/50 = 1/2
= 50% increase
Name the point located 4 units from the origin and rotated 30 degrees
(4, 30o)
Name the point located 4 units right and 3 units down from the origin.
(4, -3)
Name the point 4 units forward, 3 units left and 1 unit up from the origin
(4, -3, 1)
What do the letters in PEMDAS stand for?
Parentheses/Grouping Symbols
Exponents
Multiplication/Division
Addition/Subtraction
Calculate the percent decrease from 12 to 9
(12-9)/12
= 3/12 = 1/4
= 25% decrease
Name the point located 2 units from the origin and rotated 90 degrees
(2, 90o)
Name the point located 1 unit left and 3 units up from the origin.
(-1, 3)
Name the point 2 units backward, 4 units right and 1 unit up from the origin
(-2, 4, 1)
What operations are grouped in the order of operations?
Multiplication/Division
Addition/Subtraction
Calculate the percent decrease from 60 to 48
(60-48)/60
= 12/60 = 1/5
= 20% decrease
Name the point located 5 units from the origin and rotated 150 degrees
(5, 150o)
Name the point located 4 units left and 7 units down from the origin.
(-4, -7)
Name the point 6 units backward, 2 units left and 3 units down from the origin
(-6, -2, -3)
What is the first step in simplifying the expression: 4+7(3+3)-1
Add the numbers in the parentheses
Calculate the percent decrease from 30 to 21
(30-21)/30
= 9/30 = 3/10
= 30% decrease
Name the point located 10 units from the origin and rotated COUNTERCLOCKWISE 60 degrees
(10, 300o)
Hint: 360o - 60o = 300o
