what is the inverse of f(x)=2-2x

Answers

Answer 1
In the usual sense, it has no inverse function. Since it is not an injection (f(0)=f(2)=0), an inverse function would have to map 0 both to 0 and 2, and that’s impossible.

However, if you restrict the domain to [1,+oo> (to make it injective), and the codomain to [-1,+oo> (to make it surjective), then it has an inverse function, given by g(y)=1+sqrt(y+1).

A scuba diver dove 40 feet below the surface. He swam up 12 feet to see a unique fish. He followed the fish down 8 feet. Then he followed the fish up 27 feet. How far below the surface is the diver now?

Answers

Answer: 9 feet below the surface.

Step-by-step explanation:

The scuba diver starts 40 ft below the surface. We can represent the position of the scuba diver as:

Position = -40ft

Where the negative sign is because it is below the surface of the water, so

"He swam up 12 feet to see a unique fish."

Now we need to add 12ft

Then his new position is:

Position = -40ft + 12 ft = -28ft

"He followed the fish down 8 feet.

Now we need to subtract 8ft

His new position is:

Position = -28ft - 8 ft = -36 ft

"Then he followed the fish up 27 feet."

Now we add another 27 ft.

The final position will be:

Position = -36ft + 27ft = -9ft

Then the final position of the scuba diver is -9ft, that means that he is 9 feet below the surface.

What are trigonometric ratios in terms of a right-angle triangle?

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, The vertical or opposite distance is 2 feet and it has an angle of 5°.

∴ The horizontal or adjacent distance can be obtained by tan(theta).

Assuming horizontal distance to be x feet.

∴ tan(5°) = 2/x feet.

x = 2/tan(5°).

x = 22.9 feet.

Adam has 3 coins in his pocket and they are all different from each other. Ben has 3 coins in his pocket and they are all the same as each other. Adam has half as much money as Ben.
What are the coins they each have?

Answers

Answer:

The possible coins are:

P = penny = $0.01

N = nickel = $0.05

D = dime = $0.10

Q = quarter = $0.25

H = half dollar = $0.50

We know that Adam has 3 coins in his pocket, and all of them are different, then the money that Adam has can be represented with (A + B + C)

Behn has 3 coins, and all of them are the same, then if his coin has a value X, he has a total of 3*X

We know that Adam has half as much money as Ben, this can be written as:

(A + B + C) = 3*X/2

The easier way to solve this, is to play with different values of X, and see if we can find the values of A, B and C.

For example, if X = $0.10

then:

(A + B + C) = $0.10*(3/2) = $0.15

We can find 3 different value of coins for this equation? No, we cant, so X = $0.10 is also discarded.

if x = $0.50 then:

(A + B + C) = (3/2)*$0.50 = $0.75

Here we could have:

A = $0.50

B = $0.25

then: A + B = $0.75

But we still have the coin C.

If we take X = $0.25 then:

(A + B + C) = (3/2)*$0.25 = $0.375

We could round the right part to $0.40

then the coins in the left part would be:

A = $0.25

B = $0.10

C = $0.05

A + B + C =  $0.25 + $0.10 +  $0.05 = $0.40

In this extract, the narrator discusses what his life is like now, long after a traumatic ordeal with a ghostly woman who stole the life of his only son.CHRISTMAS EVEIt was nine-thirty on Christmas Eve. As I crossed the long entrance hall of Monks Piece on my way home from the dining room, where we had just enjoyed the first of the happy, festive meals, towards the drawing room and the fire around which my family were now assembled, I paused and then, as I often do in the course of an evening, went to the front door, opened it and stepped outside.I have always liked to take a breath of the evening, to smell the air, whether it is sweetly scented and balmy with the flowers of midsummer, pungent with the bonfires and leaf-mould of autumn, or crackling cold from frost and snow. I like to look about me at the sky above my head, whether there are moon or stars or utter blackness, and into the darkness ahead of me; I like to listen for the cries of nocturnal creatures and the moaning rise and fall of the wind, or the pattering of rain in the orchard trees, I enjoy the rush of air towards me up the hill from the flat pastures of the river valley.Tonight, I smelled at once, and with a lightning heart, that there had been a change in the weather. All the previous week, we had had rain, chilling rain and a mist that lay low about the house and over the countryside. From the windows, the view stretched not farther than a yard or two down the garden. It was wretched weather, never seeming to come fully light, and raw, too. There had been no pleasure in walking, the visibility was too poor for any shouting and the dogs were permanently morose and muddy. Inside the house, the lamps were lit throughout the day and the walls of larder outhouse and cellar oozed damp and smelled sour, the fires sputtered and smoked, burning dismally low.My spirits have for many years now been excessively affected by the ways of the weather, and I confess that, had it not been for the air of cheerfulness and bustle that prevailed in the rest of the house, I should have been quite cast down in gloom and lethargy, unable to enjoy the flavour of life as I should like and irritated by my own susceptibility. But Esme is merely stung by inclement weather into a spirited defiance, and so the preparations four our Christmas holiday had this year been more than usually extensive and vigorous.I took a step or two out from under the shadow of the house so that I could see around me in the moonlight. Monks piece stands at the summit of land that rises gently up for some four hundred feet from where the little River Nee traces its winding way in a north to south direction across this fertile, and sheltered, part of the century. Below us are pastures, interspersed with small clumps of mixed, broadleaf woodland. But at our backs for several square miles it is quite a different area of rough scrub and a heathland, a patch of wildness in the midst of a well-farmed country. We are but two miles from a good-sized village, seven from the principal market town, yet there is an air of remoteness and isolation which makes us feel ourselves to be much further from civilization.

That sphere of voluntary individual, social, and economic relationships and organizations that, although limited by law, is not part of governmental institutions. Civil society provides a domain where individuals are free from unreasonable interference from government.
