I cannot help with this question, I do not see the figures or an image to go with the question. Just a bunch of numbers and letters.

the graph of y=x^2-4x is shown. name a zero of the function below

Answers

Answer:

0 and 4

Step-by-step explanation:

y = x^2 - 4x can be factored as follows:  y = x(x - 4).

We find the zeros by setting this factored form equal to zero and solving for x:

x(x - 4) = 0, or x = 0, or x = 4.

The two zeros of this function are 0 and 4.

Scott set up a volleyball net in his backyard. One of the poles, which forms a right angle with the 15) ground, is 7 feet high. To secure the pole, he attached a rope from the top of the pole to a stake 5 feet from the bottom of the pole. To the nearest tenth of a foot, find the length of the rope.

Answers

Answer:

8.6 feets

Step-by-step explanation:

From the scenario described :

The length of the rope, h is the hypotenus. From the data Given, we cannot obtain how far wthe bird will need to fly directly, we use Pythagoras rule to calculate the hypotenus of the triangle :

Hypotenus, h = sqrt(opposite² + adjacent²)

h = sqrt(7² + 5²)

h = sqrt(49 + 25)

h = sqrt(74)

h = 8.6 feet

plug in the given values:

0.7^2 + b^2 = 2.5^2

simplify:

0.49 + b^2 = 2.5^2

0.49 + b^2 = 6.25

b^2 = 5.76

b = √5.76

(15 ft.

40 ft.

Yard

Garden

75 ft.

What is the approximate area of the garden?

Ft

Answers

Answer:

The answer is below

Step-by-step explanation:

From the image attached we can see that the width of the garden is 6 ft. The length of the garden is the slanting side of the triangle (hypotenuse).

Let x be the length of the garden. The height of the triangle = 40 ft - 15 ft = 25 ft.

The base of the triangle = 80 ft - 75 ft = 5 ft.

The length of the garden is gotten using Pythagoras:

x² = 25² + 5²

x² = 650

x = 25.5 ft.

The area of the garden = length * width = 25.5 * 6 = 153 ft²

Hence the approximate area = 160 ft²

The average person's stride lenghth the distance covered by one step is aproximently 2.5 feet long. How many steps would the average person take to travel 50 feet?

Answers

Answer: 20 steps

Step-by-step explanation:

From the question, we are informed that the average person's stride length the distance covered by one step is 2.5 feet long.

To know the steps that the average person would take to travel 50 feet, we simply have to divide 50 feet by 2.5 feet. This will be:

= 50 / 2.5

= 20

This means that an individual will take 20 steps to travel 50 feet

Louise Mallard from Kate Chopins The Story of an Hour is an example of a dynamic character. Which of the following excerpts from Chopins story highlight the transformation that Louise undergoes?A. It was her sister Josephine who told her, in broken sentences; veiled hints that revealed in half concealing. Her husbands friend Richards was there, too, near her. It was he who had been in the newspaper office when intelligence of the railroad disaster was received, with Brently Mallards name leading the list of killed. He had only taken the time to assure himself of its truth by a second telegram, and had hastened to forestall any less careful, less tender friend in bearing the sad message. B. She could see in the open square before her house the tops of trees that were all aquiver with the new spring life. The delicious breath of rain was in the air. In the street below a peddler was crying his wares. The notes of a distant song which some one was singing reached her faintly, and countless sparrows were twittering in the eaves.C. She did not stop to ask if it were or were not a monstrous joy that held her. A clear and exalted perception enabled her to dismiss the suggestion as trivial. She knew that she would weep again when she saw the kind, tender hands folded in death; the face that had never looked save with love upon her, fixed and gray and dead. But she saw beyond that bitter moment a long procession of years to come that would belong to her absolutely. And she opened and spread her arms out to them in welcome.D. Some one was opening the front door with a latchkey. It was Brently Mallard who entered, a little travel-stained, composedly carrying his grip-sack and umbrella. He had been far from the scene of the accident, and did not even know there had been one. He stood amazed at Josephine's piercing cry; at Richards' quick motion to screen him from the view of his wife. -2x-10=2x+14 i need all the steps English is one language spoken in south asia due to Does anyone know the answer to this and how to solve it?One fourth of a number, decreased by 10, is -50.
