An algebraic expression is an expression built up from integer constants, variables, and the algebraic operations.
Answer:
Rotation of 90° (CounterClockwise) (x, y) (-y, x)
Rotation of 180° (Both Clockwise and Counterclockwise) (x, y) (-x, -y)
Rotation of 270° (Clockwise) (x, y) (-y, x)
Rotation of 270° (CounterClockwise)
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
choice A is not guaranteed since the values varied from 0 to 7.
choice B seems alright, but doesn't include about or anything about the long run.
choice C is incorrect because 50% are less than 3.12 and 50% are greater than 3.12.
choice D seems pretty good, since it says average, long run, approach, etc.
choice E is incorrect because it says "will be". It is not definite.
Circumference = 2 x radius x Pi
Circumference = 2 x 0.8 x pi
Circumference = 1.6pi or 5.024 yards
area = r^2 x pi
Area = 0.8^2 x pi
Area = 0.64pi or 2.0096 square yards
