Answer:
(-18, 2)
Step-by-step explanation:
To rotate a point by 90°:
R₉₀ (x, y) = (-y, x)
R₉₀ (1, 9) = (-9, 1)
To dilate by 2:
D₂ (x, y) = (2x, 2y)
D₂ (-9, 1) = (-18, 2)
Answer:
the answer is
3a/2
Step-by-step explanation:
1/2 × 3a = 3a/2
The volume of a rectangular prism (in this case, the pool) is found by multiplying the values of the length, the height, and the width together.
