The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

A comet travelling through space at a rate of 75 miles per hour has just flown into a huge amount of space dust. This dust decreases the speed of the comet by 15 miles every hour, until it completely stops moving. Which are the domain and range of the linear function that represents this relationship?
Answers
Answer:
Linear function: y = -15x + 75
Domain: x ≤ 5
Range: y ≥ 0
Please tell me if there are any mistakes in my answer and I will correct them.
Step-by-step explanation:
The linear function is y = -15x + 75, written in y=mx+b form. X is the amount of hours. Since the speed is decreasing, we will use -15. Since we started at 75 miles per hour, our b value will be 75.
DomainThe domain is all the possible values for x.
Since the comet slows down by 15 miles every hour until it stops moving, we can solve for x by putting in 0 for y.
0 = -15x + 75
15x = 75
x = 5
Therefore, the domain is x ≤ 5.
RangeThe range is the set of all possible values of y. In this case, the range can be anything but 0 in order for the equation to make sense.
So, the range is y ≥ 0.
Answer:
domain is 0,5
Step-by-step explanation:
after 5 hours, it stops moving

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Answers
Answer:
Step-by-step explanation:
The (positive) slope of the line whose domain is (-infinity, -1) is
m = rise/run = 1/1, or m = 1. The (negative) slope of the other line segment is
m = rise/run = -1/1, or m = -1.
Let's now find the equation of the line with m = 1. Using the slope-intercept form, y = mx + b, where m = +1, we get 1 = +1(-1) + b, or b = 2. Then the equation is y = x + 2 on the domain (-infinity, -1).
Now find the equation of the line with negative slope:
y = -x + b; the y-intercept is immediately evident from the graph as b = 0.
Then the desired eequation is y = -x on the domain (-1, infinity).

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
6
Step-by-step explanation:
18-2.5+7 there s your helllppppppppppp
New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet
Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.
Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:
Area = (1/2) x base x height
Area = (1/2) x 18 x 7 = 63 square feet
To find the area of the new deck, we can use the same formula and plug in the new dimensions:
Area = (1/2) x 7.2 x 2.8 = 11.88 square feet
Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.
Part C: The ratio of the areas is:
63/11.88 = 5.303
The scale factor is:
2/5 = 0.4
To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:
5.303/0.4 = 13.2575
Therefore, the ratio of the areas is 13.2575 times the scale factor.

Answer:
102
Step-by-step explanation:
Since 2 + 8 = 10, then the cube root of 5x+2 = 8
Since 8×8×8=512, then 5x+2=512
5x=510, so x=102
Answer:
C) 102
Step-by-step explanation:
Hello !
2 + ∛(5x + 2) = 10
∛(5x + 2) = 10 - 2
∛(5x + 2) = 8
(∛(5x + 2))³ = 8³
5x + 2 = 512
5x = 512 - 2
5x = 510
x = 510 : 5
x = 102
