-57 is a whole number, yes (it does not have a decimal or fraction)
$81.00
30% of 270 = 0.3 × 270 = 81
Answer:
The new coordinate of the image will be (4, 0) when the point (-4,0) is rotated 180 degrees counterclockwise using center (0,0).
i.e. [(-4,0)→(4,0)]
Step-by-step explanation:
The rule for rotation a point 180° counterclockwise about the origin states that when a point (x, y) is rotated 180° counterclockwise about the origin, the new position of the coordinates of point P(x, y) becomes (-x, -y).
Hence,
- Rotate (x, y) counterclockwise 180° about the origin: [(x,y)→(-x,-y)]
So, when the given point (-4,0) is rotated 180 degrees counterclockwise using center (0,0), the new coordinates of the image will be:
- Rotate (-4, 0) counterclockwise 180° about the origin: [(-4,0)→(4,0)]
Therefore, the new coordinate of the image will be (4, 0) when the point (-4,0) is rotated 180 degrees counterclockwise using center (0,0).
i.e. [(-4,0)→(4,0)]

Answer:
2, 6, 12, 20, 30
Step-by-step explanation:
To find the first 5 terms substitute n = 1, 2, 3, 4, 5 into the expression
n = 1 → 1² + 1 = 1 + 1 = 2
n = 2 → 2² + 2 = 4 + 2 = 6
n = 3 → 3² + 3 = 9 + 3 = 12
n = 4 → 4² + 4 = 16 + 4 = 20
n = 5 → 5² + 5 = 25 + 5 = 30
Answer:
Step-by-step explanation:
∠D ≅ ∠R
DC ≅ RK
So, If ∠C ≅ ∠K,
Then ΔDCS ≅ ΔRKO by Angle Side Angle congruent. {A S A}
OR
DC ≅ RK
∠D ≅ ∠R
If SD ≅ OR , then
ΔDCS ≅ ΔRKO by Side Angle Side congruent {S A S}
