Answer: The area of the circle with a diameter of 10 cm is 78.5 cm2.
Answer: 78.5 units²
Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle.
Area = πr²
Notice that here, we're given the diameter instead of the radius. It's important to understand that the radius is equal to half of the diameter so the radius of this circle will be equal to half of 10 or 5.
So plugging into the formula, we have (π)(5)².
A common mistake is to plug 10 into the formula but remember that we must plug in the radius and not the diameter.
Multiplying, (5)² is equal to 5 x 5 or 25 so we have 25π.
So the area of the circle is 25π.
Now, remember that π is approximately equal to 22/7 or 3.14 so we can estimate the area of the circle by plugging in 3.14 for π.
So we have (25)(3.14) which is equal to 78.5 units².
Since there were no labels, I just add units to the end.
So the area of the circle is approximately equal to 78.5 units².
Which is not a characteristic of the linear parent function?
O
A. It goes through the origin.
O
B. The range is positive real numbers (y> 0).
O
C. The domain is all real numbers.
O
D. It has a slope of 1.
The characteristic of the linear parent function that is not true is that the range is positive real numbers (y > 0).
Explanation:The correct answer is B. The characteristic of the linear parent function that is not true is that the range is positive real numbers (y > 0).
A linear parent function is represented by the equation y = x and passes through the origin (0,0). Its domain is all real numbers (-∞, ∞) and its range is also all real numbers (-∞, ∞).
A linear function with a slope of 1 is represented by the equation y = x and is a straight line that passes through every point on the graph that has the same x and y value.

Option B 'The range is positive real numbers (y>0)' is not a characteristic of the linear parent function. The function y=x, known as the linear parent function, has its range as all real numbers, not just positive.
Explanation:The characteristic of the linear parent function, which is not accurate, is: 'The range is positive real numbers (y>0)'.
The linear parent function is y = x, which indeed meets the criteria of the remaining options. It goes through the origin (0,0), its domain covers all real numbers, as x can be any real number, and it has a slope of 1 throughout. However, its range is not only positive real numbers (y>0). The range of the linear parent function actually includes all real numbers because y (the output) can take any real value, both positive and negative, not just positive.

Answer:
MN = 10
Step-by-step explanation:
To find the length of a line segment or the straight distance between two points, use the formula [tex]L = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex] , where you can substitute two points, which would be (x₁ , y₁) and (x₂ , y₂). "L" stands for length.
Choose point 1 and point 2:
Point 1: M (2, -3) x₁ = 2 y₁ = -3
Point 2: N (8, 5) x₂ = 8 y₂ = 5
Substitute the values for the variables:
[tex]L = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]L = \sqrt{(8-2)^{2}+(5-(-3))^{2}}[/tex] Solve inside each bracket first by adding
[tex]MN = \sqrt{(6)^{2}+(8)^{2}}[/tex] Square each number
[tex]MN = \sqrt{36+64}[/tex] Add the numbers
[tex]MN = \sqrt{100}[/tex] Find the square root
[tex]MN = 10[/tex] Length of the line segment
Therefore the length of the line segment MN is 10.

solve the proportional equation 3/r = 5/r+3
Answer:
r=9/2 or 4.5
Step-by-step explanation:
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get
r=9/2 or 4.5

Five times the sum of -2 and a number is 91 more than the sum of the opposite of the number and 1
Answer:
n or the number = 5
Step-by-step explanation:
5 * (-2 + n) = 91 + (-n + 1)
-10 + 5n = 19 - n + 1
6n = 20 + 10
6n/6 = 30/6
n = 5
Answer:
The number is 51.
Step-by-step explanation:
Let the number be x and the opposite of a number is -x.
5(-2+x) = 91 + (-x + 1)
-10 + x = 91-x+1
-10 + 2x = 92
2x = 102
x = 51

Australia is approximately 3,000,000 square
miles in area. Sand dunes cover 40% of the land.
How much of Australia is
covered by sand dunes?
Answer:
1,200,000 square miles
Step-by-step explanation:
Given data:
Total land = 3 000 000
40% is covered by sand dunes
Land covered by sand dunes is 40% of the total area therefore
Land covered by sand dunes=(40/100) * 3000000
Land covered by sand dunes= 0.4 * 3000000
Land covered by sand dunes= 1 200 000
Final answer:
Approximately 1,200,000 square miles of Australia are covered by sand dunes, which is 40% of Australia's total area of about 3,000,000 square miles.
Explanation:
The student has asked how much of Australia is covered by sand dunes given that Australia's area is approximately 3,000,000 square miles and sand dunes cover 40% of the land.
To calculate the area covered by sand dunes, we apply the percentage to Australia's total area:
Convert the percentage into decimal form: 40% = 0.40.
Multiply the total area of Australia by the decimal: 3,000,000 square miles × 0.40.
The result gives us the area covered by sand dunes: 1,200,000 square miles.
Therefore, sand dunes cover about 1,200,000 square miles of Australia.

plz help
The surface area of prism is 185.815 square inches
Solution:
Given that,
[tex]Length = 2\frac{1}{3}\ inches = \frac{3 \times 2 + 1}{3} = \frac{7}{3}\ inches = 2.33\ inches[/tex]
[tex]Width = 8\frac{1}{2}\ inches = \frac{17}{2}\ inches = 8.5\ inches[/tex]

[tex]A=2(wl+hl+hw)[/tex]
Where,
"l" is the length
"w" is the width
"h" is the height

What is the parallel line to y=-4x-5 and passes the point (-2,6)
Answer:
y = - 4x - 2 is the required equation of the line.
Step-by-step explanation:
Equation of two parallel lines differ only by a constant.
If the equation of a line is [tex]$ ax + by + l = 0 $[/tex] then the equation of the line parallel to it is given by [tex]$ ax + by + k = 0 $[/tex].
Note that only the constants differ in both the equations.
The given equation is: y = - 4x - 2
This is equivalent to 4x + y + 2 = 0.
Therefore, the equation of the line parallel to the given line will be:
4x + y + k = 0.
We are also given the point which passes through the line. We can substitute it to determine the value of 'k'.
Substituting (- 2, 6), we get:
4(-2) + 6 + k = 0
⇒ - 8 + 6 + k = 0
⇒ k = 2
Hence, the equation of the required line is: y = - 4x - 2
