The algebraic rule describes the 180° counter-clockwise rotation about the origin =======> Answer: Rule for 180 degrees Counter-Clockwise Rotation =======> ( X , Y ) =========> ( - X, - Y ) ====> Make X + Y Signs Opposite.
Rotations Counter-Clockwise:
Rotation of 90 degrees ========> Switch X + Y, Make Y Opposite.
Rotation of 270 degrees ======> ( X, Y ) ===> ( Y, - X ) ==> Switch X + Y, Make X Opposite.
Hope that helps!!!! : )
Part A: There are five buttons in all in all in the given item. The item above can be answered through the fundamental principles of counting.
There are 5 items to choose from during the first pick. Because the shape can be returned and picked again, there are also 5 items to choose from in the second pick. Multiplying them,
n = 5 x 5 = 25
Therefore, the sample size for the compound event is equal to 25.
Part B: The same concept can be used in this part of the item; however, instead of 5 there are 6 buttons to choose from.
n = 6 x 6 = 36
Hence, the sample size of this picking process is 36.
The distance travelled by east bound car is 60 km.
<u>Explanation:</u>
Distance travelled by North bound plane = 63 km
Distance travelled by east bound plane = 87 km
Distance travelled by east bound plane = ?
The trajectory of the plane would form a triangle.
In a right angle triangle:
(hypotenuse)² = (base)² + (height)²
(87)² = (b)² + (63)²
7569 = b² + 3969
b² = 3600
b = 60 km
Therefore, distance travelled by east bound car is 60 km.
Answer:
Step-by-step explanation:
20% of 1150 is 230, so 1150-230=920
if the tax is applied after the discount, you find 10% of 920 (which is 92)
you add that to the discounted price 920+92= 1012, so they could go to florida.
Answer:
5%
Step-by-step explanation:
720/144=5
