Find a formula for the inverse of the function. f(x) = e^6x − 9
STatiana [176]

Answer:

f^{-1}(x)=\frac{1}{6}\ln(x+9)

Step-by-step explanation:

So we have the function:

f(x)=e^{6x}-9

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

x=e^{6f^{-1}(x)}-9

Add 9 to both sides:

x+9=e^{6f^{-1}(x)}

Take the natural log of both sides:

\ln(x+9)=\ln(e^{6f^{-1}(x)})

The right side cancels:

\ln(x+9)=6f^{-1}(x)

Divide both sides by 6:

f^{-1}(x)=\frac{1}{6}\ln(x+9)

And we're done!

Which of the following is NOT a formula for determining complementary probability?
forsale [732]

<em>Question:</em>

<em>Which of the following is NOT a formula for determining complementary probability?</em>

<em>A. P(outcome) = 1- P(-outcome)</em>

<em>B. P(outcome) - P(-outcome) = 1</em>

<em>C. P(outcome) + P(-outcome) =1</em>

<em>D. P(-outcome) = 1 - P(outcome)​</em>

<em></em>

Answer:

P(outcome) - P(-outcome) = 1

Step-by-step explanation:

Required

Determine which option is not a formula of complementary probabilities

From the list of given options, the complementary probabilities are P(outcome) and P(-outcome)

In probability;

P(outcome) + P(-outcome) = 1 --- Equation 1

Subtract P(outcome) from both sides

P(outcome) - P(outcome) + P(outcome) = 1 -  P(outcome)

P(-outcome) = 1 - P(outcome)  ------ Equation 2

Subtract P(-outcome) from both sides of equation 1

P(outcome) + P(-outcome) - P(-outcome) = 1 -  P(-outcome)

P(outcome)  = 1 -  P(-outcome)

Equation 1, 2 and 3 represents options A, C and D

While option B is out of place

<em>Hence, option B is not a formula of complementary probability</em>

5/3

Csc is equal to 1/sin

Sin= opposite/hypotenuse

So just take the inverse of what sine would be

Sin= 3/5

So Csc=5/3 :)
