What is the inverse one to one function of f(x) = square root of x-2???

1 answer:

6 0

$f(x) = \sqrt{x - 2} \\y = \sqrt{x - 2} \\y^{2} = (\sqrt{x - 2})^{2} \\y^{2} = x - 2 \\x^{2} = y - 2 \\x^{2} + 2 = y \\x^{2} + 2 = f^{-1}(x)$

a machinest can produce 114 parts in 6 minutes.at this rate,how many parts can the machinist produce in 15 minutes

JulsSmile [24]

The first thing we need to do is find the rate of parts for 15 minutes.

So, we divide 114 parts per 6 minutes and get 19 parts per minute

Then we multiply this rate per minute by 15 minutes

The answer is 285

Attached Work Below:

$Part1\\114\div6=19\\\\Part 2\\19\times15=285$

The shortest distance from a point to a straight line is

Dahasolnce [82]

The shortest distance from a point to a straight line is the measurement of the line segment which connects the point to the straight line. This line segment should be perpendicular to the line and is thus called the perpendicular distance.

Which of the following is the algebraic expression that best describes the sequence 3,6,9,12 ?

Novay_Z [31]

I don't see any choices so I am going to give you what I think the answer would be. The rule would be 3x. That would be you could plug any number in and they would give you the sequence. Example:
x = 1
x times 3 = 3.
We could even find future things like:
x = 10
x times 10 = 30.
If we were doing it based on the algebraic expression it would be "multiplication" because we are multiplying. Hope this helped. :)

What’s 7,040 divide by 3 using long division

gizmo_the_mogwai [7]

Answer:

Dividing 7,040 by 3 using long division method it gives the quotient <u>2346</u> and the remainder <u>2</u>.

Step-by-step explanation:

Given:

7,040 divide by 3 using long division.

Now, to divide using long division method:

Step 1: Divide 7 by 3. 3 x 2 =6.

So, 1 will be remainder.

Step 2: Bring 0 down next to 1. So, now the new number is 10 .

Divide 10 by 3. 3 x 3 = 9.

Remainder is 1

So, quotient is 23 till now.

Step 3: Bring 4 down next to 1. The number is now 14.

Divide 14 by 3. 3 x 4 = 12.

Thus, remainder is 2.

Step 4: Bring 0 next to 2. Getting the new number 20.

So, divide 20 by 3. 3 x 6 = 18.

Thus, the remainder is 2.

So, the quotient is 2346.

And the remainder is 2.

Therefore, dividing 7,040 by 3 using long division method it gives the quotient 2346 and the remainder 2.
