Answer:
Step-by-step explanation:
<em>A = 1/4√5(5+2√5)a²</em>
<em></em>
The number is 20. Work in picture if you want it or want justification of steps:)
B. 12 weeks (.084 x 12 = 1.008 + .09 = 1.098)
It is helpful to plot the points, then mentally test the answers for plausibility. Translation of E 1 unit to the right puts it at (2, 1), then rotation counterclockwise 90° about the origin puts it at (-1, 2), the location of E'.
The appropriate choice seems to be
A translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin_____
Translation 1 unit right: (x, y) ⇒ (x+1, y)
Rotation 90° CCW: (x, y) ⇒ (-y, x)
Both transformations in that order: (x, y) ⇒ (-y, x+1)
Answer:
9120
Step-by-step explanation:
I'm assuming you mean LCM (Least Common Multiple).
Factor each number into powers of primes.
76 = 2²×19
96 = 2⁵×3
120 = 2³×3×5
Take the highest power of each prime used: 2⁵, 3, 5, 1
The LCM is their product: 2⁵×3×5×19 - 9120
