Answer:
< 8, 4 >
Step-by-step explanation:
Consider the coordinates
x- coordinate A - 3 → A' 5 → that is + 8
y- coordinate A 1 → A' 5 → that is + 4
Hence T = < 8, 4 >
or (x, y) → (x + 8, y + 4)
The intensity of sound which the decibel level of the sound measures 156 is 3.981 × 10³ W/m²
Decibel level, dB = 10log₁₀(I/I₀) where dB = decibel level = 156, I = intensity at 156 dB and I₀ = 10⁻¹² W/m².
Since we require I, making I subject of the formula, we have
dB/10 = log₁₀(I/I₀)
Substituting the values of the variables into the equation, we have
I = 3981.072W/m²
I = 3.981 × 10³ W/m²
So, the intensity of sound which the decibel level of the sound measures 156 is 3.981 × 10³ W/m²
