An expression is defined as a set of numbers, variables, and mathematical operations. The expressions that are equivalent to the given expression is -3+2i - 2(24) - 8i and -51 - 6i.

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression can be simplified as,

(-√9 + √-4) - (2√576 + √-64)

= (-3+2i) - 2(24) - 8i

= -3+2i - 2(24) - 8i

= -3 + 2i - 42 - 8i

= -51 - 6i

Hence, the expressions that are equivalent to the given expression is -3+2i - 2(24) - 8i and -51 - 6i.

f(x) = 3x + 10, g(x) = x - 2, Find g(f(x))

Answers

Answer with step-by-step explanation:

If g(x) = x - 2, then g(f(x)) = f(x) - 2. So the whole equation would be: 3x + 10 × x - 2. Simplified: g(f(x)) = 13x - 2

Hope this helped!

The composite function g(f(x)) = 3x + 8 if the f(x) = 3x + 10, g(x) = x - 2 after applying the concept of the composite function.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

f(x) = 3x + 10

g(x) = x - 2

It is required to find the g(f(x))

g(f(x)) representing the composite function:

Plug f(x) = 3x + 10

In the function g(x):

g(f(x)) = (3x + 10) - 2

g(f(x)) = 3x + 8

Thus, the composite function g(f(x)) = 3x + 8 if the f(x) = 3x + 10, g(x) = x - 2 after applying the concept of the composite function.

Sound intensity, in decibels, d, can be written using a comparison factor, x, that compares sound intensity to the standard threshold of hearing. d = 10log(x) A sensor measures the sound intensity, in decibels, of an office over time. The decibel reading was consistently above 50, but never above 70. On what interval is the factor by which the office noise is related to the standard threshold of hearing? (17, 18.5) (17, 18.5] (100,000, 10,000,000] (100,000, 10,000,000)

Answers

Answer: (100,000, 10,000,000]

Step-by-step explanation:

The interval is given by ( 100,000 , 10,000,000], the correct option is C.

What is the Threshold Value ?

The threshold value is the minimum value above which the desired results can be expected.

The decibel reading was consistently above 50, but never above 70.

d = 10log(x)

50 = 10log(x)

5 = log x

10⁵ = x

x > 10⁵

d = 10log(x)

70 = 10log(x)

x = 10⁷

From the given data

x ≤ 10⁷

Therefore, the interval is given by ( 100,000 , 10,000,000], the correct option is C.

  m∠YPQ = 159°

Step-by-step explanation:

m∠QRP = 107

m∠RQP = 52

m∠RPQ = x

m∠QRP + m∠RQP + m∠RPQ = 180°

107 + 52 + x = 180

159 + x = 180

x = 21°

m∠RPQ = x = 21°

m∠RPQ + m∠YPQ = 180°

21° + m∠YPQ = 180°

m∠YPQ = 159°
