Inverse function for f (x) = square root 2x-6

Mathematics
1 answer:
pishuonlain [190]3 years ago
4 0

Answer:

(x^2 +6)/2

or  1/2 x^2 +3

Step-by-step explanation:

f(x)= sqrt(2x-6)

y =sqrt(2x-6)

To find the inverse function, we interchange the x and y and solve for y

x = sqrt(2y-6)

Square each side

x^2 = sqrt(2y-6)^2

x^2 = 2y-6

Add 6 to each to each side

x^2 +6 = 2y-6+6

x^2 +6 = 2y

Divide each side by 2

(x^2 +6)/2 = 2y/2

(x^2 +6)/2 = y

The inverse function is

(x^2 +6)/2

or  1/2 x^2 +3

For the first question, the answer is A. You take 90 and multiply it by 3, then you get the time that it takes for one worker to mow the large park. 

For the second question, you take 50 = k/0.25. To find k, you would want to multiply both sides with 0.25 to cancel the 0.25 on k's side. 50 times 0.25 is 12.5. I think C is your answer although I'm not really confident.

A set of composite numbers less than 12 .express it in listing and set builder methods​
marusya05 [52]

Given:

A set of composite numbers less than 12.

To find:

The set by listing and set builder methods​.

Solution:

Composite number: A positive integer is called a composite number if it has at least one divisor other than 1 and itself.

Composite numbers less than 12 are 4, 6, 8, 9, 10.

By using the listing method , the given set can be expression as:

Set = {4, 6, 8, 9, 10}

The numbers 4, 6, 8, 9, 10 are greater than 1, less than 12 and non prime numbers.

By using set builder method, the given set can be expression as:

Set = \{x|x\neq P,1

Therefore, the list and set builder notation of the given set are {4, 6, 8, 9, 10} and \{x|x\neq P,1 respectively.

x(0.25)+(2x-1)(0.10)=5.30

0.25x+0.2x-0.10=5.30

0.45x=5.40

x=12

12 quarters
