: $\implies$ $\sf 3x⁰+45⁰+90⁰ = 180⁰$

: $\implies$ $\sf 3x⁰+135⁰ = 180⁰$

: $\implies$ $\sf 3x⁰ = 45⁰$

: $\implies$ $\sf x = \dfrac{45}{3}$

: $\implies$ $\sf x = 15⁰$

hence, last option is right

Which of the following is equal to the function below? (7/4)^11

solmaris [256]

Answer:

Therefore the correct option is A. 7^11/4^11

$(\dfrac{7}{4})^{11}=\dfrac{7^{11}}{4^{11}}$

Step-by-step explanation:

Given:

$(\dfrac{7}{4})^{11}$

Solution:

We know the Identity For Law of Indices

$(\dfrac{x}{y})^{a}=\dfrac{x^{a}}{y^{a}}$

So here we have,

x = 7

y = 4

a = 11 , then

$(\dfrac{7}{4})^{11}=\dfrac{7^{11}}{4^{11}}$

Therefore the correct option is A. 7^11/4^11

$(\dfrac{7}{4})^{11}=\dfrac{7^{11}}{4^{11}}$

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)

$\frac{I}{I_{0} } = 10^{\frac{dB}{10} } \\I = I_{0} 10^{\frac{dB}{10} }$

Substituting the values of the variables into the equation, we have

$I = I_{0} 10^{\frac{dB}{10} }\\I = 10^{-12} 10^{\frac{156}{10} }\\I = 10^{-12} 10^{15.6}\\I = 10^{15.6-12} \\I = 10^{3.6} W/m^{2}$

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
