b) Find the measurements of a rectangk with a perimeter of
26cm and an area of 1600cm​

Answers

Answer 1

Answer:

b) Find the measurements of a rectangk with a perimeter of

26cm and an area of 1600cm​

There is no way to get an area of 1600 cm using a perimeter as small as 26 cm.

Step-by-step explanation:

perimeter = 2(L + W) = 26, then L + W = 13, so L = 13 - W

area = L x W = 1600

substitute for L:

(13 - W)W = 1600

13W - W² = 1600

-W² + 13W = 1600

-W² + 13W - 1600 = 0

W² - 13W + 1600 = 0

Not possible

Given sin y = -4/5, where π < y < 3π/2, and cos x = 12/13, where 0 < x < π/2. Find the exact value of sin (x - y).

Please show all the exact steps in order I am really lost on how to solve this.

Answers

Answer:

Solution given:

sin y = -4/5

p/h=4/5

p=4

h=5

b=√{5²-4²)=3

cos y = b/h=-3/5

again

cos x=12/13

b/h=12/13

b=12

h=13

p=√(13²-12²)=5

sin x=p/h=5/13

now

sin[x-y]=sinxcosy-cosxsiny

=5/13×-3/5-(12/13×-4/5)=33/65 is your answer.

If f (-8)= 0 and f (x)= x^3-x^2-58x+112, find all the zeros of f(x) write your answer in ascending order

Answers

Answer:

The zeros in ascending order are 2, 7, 8.

Step-by-step explanation:

Since f(-8) = 0, it means that (x + 8) is a factor of the function f(x)= x³ - x² - 58x + 112.

I have attached the long division of this to get the remaining factors of the polynomial function.

The remaining factor is;

x² - 9x + 14

Using quadratic formula via a calculator, we have; x = 7 and x = 2

Thus,the zeros of the polynomial function f(x)= x³ - x² - 58x + 112 in ascending order are;

2, 7, 8

Erik read a total of 4 books over 2 months. After belonging to the book club for 17 months, how many books will Erik have read in all? plss hep me thank you!!

Answers

Answer: 34 books

Step-by-step explanation:

Since Erik read a total of 4 books over 2 months. This means that every month, he read (4/2) = 2 books.

After belonging to the book club for 17 months, the number of books that he'll have read will be the number of books he read per month multiplied by 17 months. This will be:

= 2 × 17

= 34 books

Coursing through the heart of America, it supplies water for the cities and industries that have located along its banks. In 1705 the first cargo was floated down the river from the Indian country around Wabash. This was a load of 15,000 bear and deer hides.. The Mississippi River is the main stem of a network of inland navigable waterways which form a system of about 12,350 miles in length. from The Adventures of Tom Sawyer, by Mark Twain Toms mind was made up now. He was gloomy and desperate. He was a forsaken, friendless boy, he said; nobody loved him; when they found out what they had driven him to, perhaps they would be sorry; he had tried to do right and get along, but they would not let him; since nothing would do them but to be rid of him, let it be so; and let them blame him for the consequenceswhy shouldn't they? What right had the friendless to complain? Yes, they had forced him to it at last: he would lead a life of crime. There was no choice. (Tom is now joined by Joe)As the two boys walked sorrowing along, they made a new compact to stand by each other and be brothers and never separate till death relieved them of their troubles. Then they began to lay their plans. Joe was for being a hermit, and living on crusts in a remote cave, and dying, some time, of cold and want and grief; but after listening to Tom, he conceded that there were some conspicuous advantages about a life of crime, and so he consented to be a pirate. Three miles below St. Petersburg, at a point where the Mississippi River was a trifle over a mile wide, there was a long, narrow, wooded island, with a shallow bar at the head of it, and this offered well as a rendezvous. It was not inhabited; it lay far over toward the further shore, abreast a dense and almost wholly unpeopled forest. So Jackson's Island was chosen. Who were to be the subjects of their piracies was a matter that did not occur to them.Question:Which best compares and contrasts these two passages featuring the Mississippi River?A.
