now lidl (1 - W+'+(+-00)Find the cube roots of 8. |
|
Answer» 8=2×2×2Therefore cubic root of 8 is 2 The cube roots of8are2,2ωand2ω2whereω=−12+√32iis the primitive Complex cube root of1. Explanation: Here are the cube roots of8plotted in the Complex plane on the circle of radius2: They can be written as: 2(cos(0)+isin(0))=2 2(cos(2π3)+isin(2π/3))=−1+√3i=2ω 2(cos(4π3)+isin(4π/3))=−1−√3i=2ω2 One way of finding these cube roots of8is to find all of the roots ofx3−8=0. x3−8=(x−2)(x2+2x+4) The quadratic factor can be solved usingthe quadratic formula: x=(−b±√(b²−4ac))/2a =−2±√22−(4×1×4)/2⋅1 =−2±√−122 =−1±√3 |

Before you readDiscuss in class: Do you like homework? Do youdo it yourself. or do you get help? Whathomework do you usually have?Who Did Patrick'sHomework? |
|
Answer» WHO DID PATRICK'S HOMEWORK? Patrick never did homework. "Too boring," he said. He played baseball and basketball and Nintendo instead. His teachers told him, "Patrick! Do your homework or you won't learn a thing." And it's true, sometimes he did feel like a ding-a-ling. But what could he do? He hated homework. Then on St. Patrick's Day his cat was playing with a little doll and he grabbed it away. To his surprise it wasn't a doll at all, but a man of the tiniest size. He had a little wool shirt with old fashioned britches and a high tall hat much like a witch's. He yelled, "Save me! Don't give me back to that cat. I'll grant you a wish, I promise you that." Patrick couldn't believe how lucky he was! Here was the answer to all of his problems. So he said, "Only if you do all my homework 'til the end of the semester, that's 35 days. If you do a good enough job, I could even get A's." The little man's face wrinkled like a dishcloth thrown in the hamper. He kicked his legs and doubled his fists and he grimaced and scowled and pursed his lips, "Oh, am I cursed! But I'll do it." And true to his word, that little elf began to do Patrick's homework. Except there was one glitch. The elf didn't always know what to do and he needed help. "Help me! Help me!" he'd say. And Patrick would have to help -- in whatever way. "I don't know this word," the elf squeeked while reading Patrick's homework. "Get me a dictionary. No, what's even better. Look up the word and sound it out by each letter." When it came to math, Patrick was out of luck. "What are times tables?" the elf shrieked. "We elves never need that. And addition and subtraction and division and fractions? Here, sit down beside me, you simply must guide me." Elves know nothing of human history, to them it's a mystery. So the little elf, already a shouter, just got louder "Go to the library, I need books. More and more books. And you can help me read them too." As a matter of fact every day in every way that little elf was a nag! Patrick was working harder than ever and was it a drag! He was staying up nights, had never felt so weary, was going to school with his eyes puffed and bleary. Finally the last day of school arrived and the elf was free to go. As for homework, there was no more, so he quietly and slyly slipped out the back door. Patrick got his A's; his classmates were amazed; his teachers smiled and were full of praise. And his parents? They wondered what had happened to Patrick. He was now the model kid. Cleaned his room, did his chores, was cheerful, never rude, like he had developed a whole new attitude. You see, in the end Patrick still thought he'd made that tiny man do all his homework. But I'll share a secret, just between you and me. It wasn't the elf; Patrick had done it himself! |

Answer» 1) the point lies on x axis hence its y coordinate will be zero. It is 7 units from the y axis, which means that its x coordinate is 7.Therefore its coordinate is (7,0) 2)the point lies on the y axis, hence its x coordinate is 0. Since it lies at a distance of -7 from the x axis, ie it is below the x axis, its y coordinate is -7.Hence, its coordinates will be (0,-7). 1) the point lies on x axis hence its y coordinate will be zero. It is 7 units from the y axis, which means that its x coordinate is 7.Therefore its coordinate is (7,0) 2)the point lies on the y axis, hence its x coordinate is 0. Since it lies at a distance of -7 from the x axis, ie it is below the x axis, its y coordinate is -7.Hence, its coordinates will be (0,-7). Hope it helps you.. |

How many ways 10 hats of different colours can be put on the heads of10 boys sitting in a row, so that the red and the black coloured hats cannever be put on the heads of any two adjacent boys? |
|
Answer» The answer would be 10! if there were no restrictions. If the hats were: A B C D E F G H I J and there were no restrictions they could be arranged in 10! ways From that 10! we must subtract the number of non-allowable ways. Suppose the red hat is hat A and the black hat is hat B. Then we must subtract the 9! ways they could be arranged with hat A and hat B together, with hat A left of B: AB C D E F G H I J And we must also subtract the 9! ways they could be arranged with hat A and hat B together, with hat B left of hat A: BA C D E F G H I J Answer: 10! - 2*9! = 3628800 - 2*(362880) = 2903040 |
