Answer 1

Answer:

Step-by-step explanation:

this is just to confuse us.

"t" is used instead of "x" (probably because the formula has something to do with "time"). but it does not matter.

and 3 different functional definitions have been given based on the value of the argument "t".

we need the functional value for t=2.

is 2 = 8 ? no. therefore the first definition does not apply.

is 2 = 10 ? no. therefore the second definition does not apply either.

is 2 unequal to 8 or 10 ? yes, 2 is 2 and not 8 and not 10.

so, the third definition applies :

f(2) = 2² - 3×2 + 2 = 4 - 6 + 2 = 0

A shop keeper buys a pair of shoes for birr 180 and sells it for birr 225 what is the percentage profit

Answers

Answer:

Percentage profit = 20%

Step-by-step explanation:

Given the following data;

Cost price = birr 180

Selling price = birr 225

To find the percentage profit;

First of all, we would determine the profit;

Profit = selling price - cost price

Profit = 225 - 180

Profit = birr 45

Next, we would determine the percentage profit;

[tex] Percentage \; profit = \frac{profit}{selling \; price} * 100[/tex]

[tex] Percentage \; profit = \frac{45}{225} * 100[/tex]

[tex] Percentage \; profit = 0.2 * 100[/tex]

Percentage profit = 20%

What is Number system?

A number system is defined as a system of writing to express numbers.

A sand dollar is 2 units away from rock and five units away from palm tree, We have to find the location of the sand dollar

Let the rock is at -2 on number line

The palm tree is at 5 on number line

So the sand dollar is at 0, as zero is two units away from rock and tree is five units away

Hence, the sand dollar is at zero which is 2 units away from rock and five units away from palm tree

Answers

Answer:

a dilation with a scale factor greater than 1 and then a translation (the last option)

The composition of transformation is a dilation with a scale factor greater than 1 and then a translation.

What is Translation?

A translation only moves a shape up, down, or from side to side; it has no effect on how it appears.

We have a transformations maps LMN to L'M'N'.

As the size of Triangle L'M'N' is larger as compared to LMN.

The compression is represented by a scale factor with an absolute value between 0 and 1, while the enlargement is represented by a scale factor with an absolute value greater than 1.

Thus, dilation with a scale factor greater than 1 and then a translation.

Answer:

5/12 hour or 25 minutes

Step-by-step explanation:

The formula is

distance = rate * time

changing minutes to hours (50 * 1 /60 ) = 5/6 hours

distance = 20 mph * 5/6 hours

distance = 50/3 miles

We need to go the same distance at 40 mph

50/3 = 40 mph * time

Multiply each side by 1/40

50 /3 * 1/40 = 40 * 1/40 *t

50/3 *1/40 =t

5/12 of an hour

Changing back to minutes

whats the length of the middle segment ? Find the limit of the function by using direct substitution Lim x-0(x^2+10) from The Adventures of Tom Sawyerby Mark TwainSATURDAY morning was come, and all the summer world was bright and fresh, and brimming with life. There was a song in every heart; and if the heart was young the music issued at the lips. There was cheer in every face and a spring in every step . . . Tom appeared on the sidewalk with a bucket of whitewash and a long-handled brush. He surveyed the fence, and all gladness left him and a deep melancholy settled down upon his spirit. . . .He began to think of the fun he had planned for this day, and his sorrows multiplied. Soon the free boys would come tripping along on all sorts of delicious expeditions, and they would make a world of fun of him for having to workthe very thought of it burnt him like fire. . . . At this dark and hopeless moment an inspiration burst upon him! . . .He took up his brush and went tranquilly to work. Ben Rogers hove in sight presentlythe very boy, of all boys, whose ridicule he had been dreading. Ben's gait was the hop-skip-and-jump-proof enough that his heart was light and his anticipations high. He was eating an apple, and giving a long, melodious whoop, at intervals, followed by a deep-toned ding-dong-dong, ding-dong-dong, for he was personating a steamboat. . . .Tom went on whitewashingpaid no attention to the steamboat. Ben stared a moment and then said: "Hi-Yi! You're up a stump, ain't you!"No answer. Tom surveyed his last touch with the eye of an artist, then he gave his brush another gentle sweep and surveyed the result, as before. Ben ranged up alongside of him. Tom's mouth watered for the apple, but he stuck to his work. Ben said:"Hello, old chap, you got to work, hey?"Tom wheeled suddenly and said:"Why, it's you, Ben! I [wasn't] noticing.""SayI'm going in a-swimming, I am. Don't you wish you could? But of course you'd [rather] workwouldn't you? Course you would!"Tom contemplated the boy a bit, and said:"What do you call work?""Why, ain't that work?"Tom resumed his whitewashing, and answered carelessly: "Well, maybe it is, and maybe it ain't. All I know, is, it suits Tom Sawyer.""Oh come, now, you don't mean to let on that you like it?" The brush continued to move."Like it? Well, I don't see why I oughtn't to like it. Does a boy get a chance to whitewash a fence every day?" . . ."Say, Tom, let me whitewash a little."Tom considered, was about to consent; but he altered his mind:"NonoI reckon it wouldn't hardly do, Ben. You see, Aunt Polly's awful particular about this fence . . . it's got to be done very careful; I reckon there ain't one boy in a thousand, maybe two thousand, that can do it the way it's got to be done.""Nois that so? Oh come, nowlemme just try. Only just a littleI'd let you, if you was me, Tom.""Ben, I'd like to, honestbut Aunt Pollywell[if] you was to tackle this fence and anything was to happen to it""Oh, shucks, I'll be just as careful. Now lemme try. SayI'll give you the core of my apple.""Well, hereNo, Ben, now don't. I'm afeard""I'll give you all of it!"Tom gave up the brush with reluctance in his face, but alacrity in his heart. And while the late steamer Big Missouri worked and sweated in the sun, the retired artist sat on a barrel in the shade close by, dangled his legs, munched his apple, and planned the slaughter of more innocents. There was no lack of material; boys happened along every little while; they came to jeer, but remained to whitewash.13Select all of the correct answers.How does the dialogue between Tom and Ben impact the passage as a whole?A.
