bird is flying directly above a tree you are standing 40 feet away from the tree the angle of elevation to the top of the tree is 32 degrees and the angle of elevation to the bird is 42Â° how far above the tree is the bird

Answers

Answer: 11 ft

Step-by-step explanation:

Given

The boy is standing 40 feet away from the tree

the angle of elevation for the tree is [tex]32^{\circ}\\[/tex]

the angle of elevation for the bird is [tex]42^{\circ}\\[/tex]

using figure

[tex]\frac{h+x}{40}=\tan 42^{\circ}\\h+x=40\tan 42^{\circ}\ldots (i)\\Now,\\\tan 32^{\circ}=\frac{h}{40}\\h=40\tan 32^{\circ}[/tex]

Put the value of h in equation (i)

[tex]40\tan 32^{\circ}+x=40\tan 42^{\circ}\\x=40[\tan 42^{\circ}-\tan 32^{\circ}]\\x=40[0.9-0.624]=0.276\times 40=11.04\ ft[/tex]

B 2 to the power of 2
C 6 to the power of 6
D 2 to the power of 6

We can represent the number of potential outcomes by 2 to the power 6.

What is permutation and combination?

'In mathematics, permutation relates to the act of arranging all the members of a set into some sequence or order.

The combination is a way of selecting items from a collection, such that the order of selection does not matter.'

'The power of a number says how many times to use the number in a multiplication. Powers are also called exponents or indices.'

According to the given problem,

We can assume, for two choices, we have one decision.

This can be represented as [tex]2^{1}[/tex].

Since, we have six decisions,

Representation of the potential outcomes ⇒[tex]2^{1}+2^{1} +2^{1} +2^{1} +2^{1} +2^{1}[/tex]

= [tex]2^{6}[/tex]

= [tex]64[/tex]

Hence, the representation of the number of potential outcome is 2 to the power 6.

Can someone help me with that question

Answers

Answer:

a) The required terms are:

7,10,13,16,....34

b) The required terms are:

-1,3,7,11,...35

Step-by-step explanation:

For each question we need to find the first 4 terms and the 10th term.

a) 3n + 4

Put n = 1, 2 ,3, 4 for first 4 terms, and 10 for 10th term

Put n = 1, 3(1)+4 = 3+4 = 7

Put n = 2 , 3(2)+4 = 6+4 = 10

Put n =3 , 3(3)+4 = 9+4 = 13

Put n = 4, 3(4) + 4 = 12+4 = 16

Now, Put n= 10 3(10)+4 = 30+4 = 34

So, the required terms are:

7,10,13,16,....34

b) 4n -5

Put n = 1, 2 ,3, 4 for first 4 terms, and 10 for 10th term

Put n = 1, 4(1)-5 = 4 - 5 = -1

Put n = 2 , 4(2)-5 = 8-5 = 3

Put n =3 , 4(3)-5 = 12-5 = 7

Put n = 4, 4(4) -5 = 16-5 = 11

Now, Put n= 10 4(10)-5 = 40-5 = 35

So, the required terms are:

-1,3,7,11,...35

Rasheed is buying wings and quesadillas for a party. A package of wings costs $8. A package of quesadillas costs $10. He must spend no more than $160. Rasheed’s freezer will hold a maximum of 20 packages of wings and quesadillas.

If Rasheed buys 7 packages of wings, what is the maximum number of packages of quesadillas he can buy?

Answers

Answer:

10 is maximum of packages of quesadillas.

Step-by-step explanation:

x= number of wings

y= number of quesadillas

x+y=20

8x+10y=$160

if x=7

then 7+y=20

20-7=14=y

14*10=140

8*7=56

Rasheed can't buy 20 packages, since it'll go over his budget.

So 160-56=104

And 104/10= 10 minimum

10*10=100

100+56=160

So he can buy 10 packages of quesadillas.

Question 17(Multiple Choice Worth 5 points)(MC)Read the excerpt below and then answer the question that follows:The Book of DragonsChapter III The Deliverers of Their Country, an excerptBy E. NesbitIt all began with Effie's getting something in her eye. It hurt very much indeed, and it felt something like a red-hot sparkonly it seemed to have legs as well, and wings like a fly. Effie rubbed and criednot real crying, but the kind your eye does all by itself without your being miserable inside your mindand then she went to her father to have the thing in her eye taken out. Effie's father was a doctor, so of course he knew how to take things out of eyes.When he had gotten the thing out, he said: "This is very curious." Effie had often got things in her eye before, and her father had always seemed to think it was naturalrather tiresome and naughty perhaps, but still natural. He had never before thought it curious.Effie stood holding her handkerchief to her eye, and said: "I don't believe it's out." People always say this when they have had something in their eyes."Oh, yesit's out," said the doctor. "Here it is, on the brush. This is very interesting."Effie had never heard her father say that about anything that she had any share in. She said: "What?"The doctor carried the brush very carefully across the room, and held the point of it under his microscopethen he twisted the brass screws of the microscope, and looked through the top with one eye."Dear me," he said. "Dear, dear me! Four well-developed limbs; a long caudal appendage; five toes, unequal in lengths, almost like one of the Lacertidae, yet there are traces of wings." The creature under his eye wriggled a little in the castor oil, and he went on: "Yes; a bat-like wing. A new specimen, undoubtedly. Effie, run round to the professor and ask him to be kind enough to step in for a few minutes.""You might give me sixpence, Daddy," said Effie, "because I did bring you the new specimen. I took great care of it inside my eye, and my eye does hurt."The doctor was so pleased with the new specimen that he gave Effie a shilling, and presently the professor stepped round. He stayed to lunch, and he and the doctor quarreled very happily all the afternoon about the name and the family of the thing that had come out of Effie's eye.But at teatime another thing happened. Effie's brother Harry fished something out of his tea, which he thought at first was an earwig. He was just getting ready to drop it on the floor, and end its life in the usual way, when it shook itself in the spoonspread two wet wings, and flopped onto the tablecloth. There it sat, stroking itself with its feet and stretching its wings, and Harry said: "Why, it's a tiny newt!"The professor leaned forward before the doctor could say a word. "I'll give you half a crown for it, Harry, my lad," he said, speaking very fast; and then he picked it up carefully on his handkerchief."It is a new specimen," he said, "and finer than yours, Doctor."It was a tiny lizard, about half an inch longwith scales and wings.So now the doctor and the professor each had a specimen, and they were both very pleased. But before long these specimens began to seem less valuable. For the next morning, when the knife-boy was cleaning the doctor's boots, he suddenly dropped the brushes and the boot and the blacking, and screamed out that he was burnt.And from inside the boot came crawling a lizard as big as a kitten, with large, shiny wings."Why," said Effie, "I know what it is. It is a dragon like the one St. George killed."And Effie was right. That afternoon Towser was bitten in the garden by a dragon about the size of a rabbit, which he had tried to chase, and the next morning all the papers were full of the wonderful "winged lizards" that were appearing all over the country. The papers would not call them dragons, because, of course, no one believes in dragons nowadaysand at any rate the papers were not going to be so silly as to believe in fairy stories. At first there were only a few, but in a week or two the country was simply running alive with dragons of all sizes, and in the air you could sometimes see them as thick as a swarm of bees. They all looked alike except as to size. They were green with scales, and they had four legs and a long tail and great wings like bats' wings, only the wings were a pale, half-transparent yellow, like the gear-boxes on bicycles.Which describes the effect of having multiple incidents with the specimens in this section of the story? It suggests a childlike awe. It suggests a growing creature. It suggests a lack of concern. It suggests a sense of chaos.
