Infrasound is sound below the limit that humans can hear, below 20 Hz.
Ultrasound is sound above the limit that humans can hear, above 20,000 Hz.
Let the two numbers be -x and -x - 1, then
-x(-x - 1) = 1,122
x^2 + x = 1,122
x^2 + x + 1/4 = 1,122 + 1/4
(x + 1/2)^2 = 4,489/4
x + 1/2 = sqrt(4,489/4) = + or -67/2
x = 67/2 - 1/2 = 66/2 = 33
Therefore, the two numbers are -33 and -34
Answer:
B' (-4, -4)
Step-by-step explanation:
When you dilate from the origin, you multiply the coordinate points by the scale factor.
B (-1, -1) × 4 = B' (-4, -4)
