What is a circle?'A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the center. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant'
According to the given problem,
We know,
⇒ 18 ( 18 + y ) = 24²
⇒ 324 + 18y = 576
⇒ 18y = 576 - 324
⇒ 18y = 252
⇒ y = 252/18
⇒ y = 14
Hence, we can conclude, the value of y is 14.

(1,35)(2,70)
slope = (70 - 35) / (2 - 1) = 35/1...rise = 35, run = 1
so its basically 35/1...or just 35
Answer:
35
Step-by-step explanation:
In rise over run value ( or slope ),
Rise is the unit that moved up or down while the run is the unit that moved from right to left or from left to right.
In the coordinates plane the difference between the y coordinates shows rise and difference in x coordinates shows run,
Thus, the rise over run value from (2,70) to (3,105) is,
[tex]m=\frac{105-70}{3-2}[/tex]
[tex]=\frac{35}{1}[/tex]
[tex]=35[/tex]
In the given graph a line represents the relation between distance and time,
We know that the rise over run value for a line is same as the rise over run value for any two points in the line.
Hence, the rise-over-run value for the relationship represented in the graph is 35.

Answers
The hikers are 2064 m apart
The situation forms two right angle triangle.
Right angle triangle:A right angle triangle has one of its sides as 90 degree.
Therefore,
First hiker distance
tan 37 = opposite / adjacent
tan 37° = 525 / x
x = 525 / tan 37
x = 696.711059326
x = 696. 711 m
Second Hiker distance:
tan 21 = 525 / y
y = 525 / tan 21
y = 1367.68613557
y = 1367.686 m
Distance apart = 696.711 + 1367.686 = 2064.39713557 = 2064 m

A carnival game allows a group of players to each draw and keep a marble from a bag. The bag contains 5 gold marbles, 25 silver marbles, and 70 red marbles. A player wins a large prize for drawing a gold marble and a small prize for drawing a silver marble. There is no prize for drawing a red marble. At the start of the game, the probability of winning a large prize is 0.05 and the probability of winning a small prize is 0.25. Suppose that the first player draws a silver marble and wins a small prize. What is the probability that the second player will also win a small prize? If a group of four plays the game one at a time and everyone wins a small prize, which player had the greatest probability of winning a large prize? How could the game be made fair for each player? That is, how could you change the game so that each player has an equal chance of winning a prize?
Answers
The first player had the highest probability of getting a silver marble
The game could be made fair by adding back the marble that was drawn after each draw
It is given that:
The bag contains 5 gold marbles, 25 silver marbles, and 70 red marbles.
Ques 1)
We are asked to find the probability that the second player will also win a small prize given that the first player wins a small prize.
That is we need to find the conditional probability.
Let A denote the event that first player wins the small prize.
B denote the vent that the second player wins the small prize.
A∩B denote the event that both the player wins the small prize.
Let P denote the probability of an event.
We are asked to find:
P(B|A)
[tex]P(B|A)=\dfrac{P(B\bigcap A)}{P(A)}[/tex]
Now we know that:
[tex]P(A)=\dfrac{25}{100}[/tex]
( Since out of 100 marbles 25 are silver)
Also,
[tex]P(A\bigcap B)=\dfrac{25_C_2}{100_C_2}\\\\\\P(A\bigcap B)=\dfrac{25\times 24}{100\times 99}[/tex]
Hence,
[tex]P(B|A)=\dfrac{24}{99}[/tex]
Hence, the probability that the second player will also win a small prize is:
0.242424
Ques 2)
The probability that the first player will win a large prize is:
5/100
( But the first player draws a silver marble and wins)
The probability that the second player will win a large prize is:
5/99
( Since one marble has been taken out by the first player so the second player is left with 99 choices and here also the second player draws a silver and wins the game)
Similarly,
The probability that the third player will win a large prize is:
5/98
( Since one more marble has been taken out by the second player so the third player is left with 98 choices and here also the third player draws a silver and wins the game)
The probability that the fourth player will win a large prize is:
5/97
Hence, the greatest probability of winning a gold marble is by:
Player 4. ( Since, 5/97 is greater than the rest three probabilities)
Ques 3)
The game can be made fair for each player if all have the equal choices of drawing a marble and this can be done by replacing the marbles that have been drawn out by the previous player.

Answers
The image crosses the x-axis at the points where the function f(x) = (x + 8)(x - 4) equals zero. The points are (-8, 0) and (4, 0).
Explanation:To identify the points where the image of the parabolic lens crosses the x-axis, we should find the roots of the function f(x) = (x + 8)(x - 4). A function crosses the x-axis at its roots, the points where f(x) is equal to zero.
Setting the function equal to zero gives us (x + 8)(x - 4) = 0. We can see the polynomial is already factored. The roots of the equation are x = -8 and x = 4, since these values of x will make the equation equal to zero.
So, the graph of the function crosses the x-axis at the points (-8, 0) and (4,0). This means the correct option is: (–8, 0) and (4, 0)

The width of a rectangle is one half it's length. The perimeter of the rectangle is 54 cm. What are the width and length of the rectangle?
Answers
to find the perimeter, it's the width+width+length+length so:
1/2x+1/2x+x+x=54
3x=54
x=18
the length is 18 cm and the width is 9 cm
Let width of the rectangle = x/2 (or 1/2 of x)
Remember that Area = 2L + 2W, so . . .
2x + 2(x/2) = 54
2x + (2/2)x = 54
2x + x = 54
3x = 54 --> x = 54/3 --> x = 18
So the length of the rectangle is 18 cm and the width is 18/2 = 9 cm.

Its option D.
Answer: [tex]-3^x +4[/tex]
Step-by-step explanation:
The equation for the vertical reflection of a function f(x) across the x-axis is given by :-
[tex]y=-f(x) [/tex]
The vertical shift of 'k' units of a function g(x) is given by :-

The weight of a full steel bead tire is approximately 800 grams, while a lighter wheel weighs only 700 grams. What is the weight of each tire in pounds? There are 453.592 grams in one pound. Round answers to 2 decimal places.
Answers
Answer:
800 is 1.74
700 is 1.54
Step-by-step explanation:
i just took the assignment and it was right
The weight of each tire in pounds is 1.76 pounds for the full steel bead tire and 1.54 pounds for the lighter wheel.
To find the weight of each tire in pounds, we'll first convert the weights from grams to pounds using the conversion factor provided (1 pound = 453.592 grams). Then, we'll round the answers to two decimal places.
Let's denote:
Weight of full steel bead tire = 800 grams
Weight of lighter wheel = 700 grams
Convert the weight of the full steel bead tire from grams to pounds:
[tex]\(800 \, \text{grams} \times \frac{1 \, \text{pound}}{453.592 \, \text{grams}} = 1.763698 \, \text{pounds}\)[/tex]
Rounded to two decimal places, the weight of the full steel bead tire is approximately 1.76 pounds.
Convert the weight of the lighter wheel from grams to pounds:
[tex]\(700 \, \text{grams} \times \frac{1 \, \text{pound}}{453.592 \, \text{grams}} = 1.543235 \, \text{pounds}\)[/tex]
Rounded to two decimal places, the weight of the lighter wheel is 1.54 pounds.
So, the weight of each tire in pounds is 1.76 pounds for the full steel bead tire and 1.54 pounds for the lighter wheel.
