78.5 m²
Step-by-step explanation:
The formula to find the area of a quarter of a circle: [tex]\frac{1}{4} * \pi * r^{2}[/tex], where [tex]r[/tex] is the radius (diameter ÷ 2) and the [tex]\pi[/tex] is alterable.
1) Substitute the given values into the formula.
= [tex]\frac{1}{4} * 3.14 * 10^{2}[/tex]
2) Solve it.
= [tex]\frac{1}{4} * 314[/tex]
= 78.5
3) Round it off to the nearest tenth. In this case, it has already been rounded off.

O 38
Answers
Answer:
The value of f(-2) is equal to 14.
Step-by-step explanation:
Let's define what we are given:
f(x) = 3x² - xf(-2)Recall from function notation that f(-2) is equal to x = -2 for f(x). That means we can substitute in x = -2 into f(x):
f(-2) = 3(-2)² - (-2)From here, we can evaluate the function expression using BPEMDAS (Brackets, Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction):
f(-2) = 3(-2)² - (-2)f(-2) = 3(4) - (-2)f(-2) = 3(4) + 2f(-2) = 12 + 2f(-2) = 14∴ f(-2) = 14.
Hope this helps!
F(x)=3x^2 -x
F(-2)= 3(-2)^2 -(-2)
= 3(4) +2
= 12 + 2
= 14

unit 10 circles homework 9 standard form of a circle all things algebra
Answers
1In unit 10 circles homework 9 standard form of a circle in all things' algebra, the center is (0,-2) and radius is 8 units.
What is the equation of circle?The equation of the circle is the equation which is used to represent the circle in the algebraic equation form, with the value of center point in the coordinate plane and measure of radius.
The standard form of the equation of the circle can be given as,
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Here (h,k) is the center of the circle and (r) is the radius of the circle.
For the first problem,
[tex]x^2+(y+2)^2=64[/tex]
Rewrite the equation to make it the equation of circle as,
[tex](x-0)^2+(y-(-2))^2=8^2[/tex]
Compare it with equation of circle, we get center at (0,-2) and radius of 8 units. Similarly, the center and radius for each of the equation can be found out.
Thus, in unit 10 circles homework 9 standard form of a circle in all things' algebra, the center is (0,-2) and radius is 8 units.

Answers
Answer:
f[g(x)] = 9x + 10
Step-by-step explanation:
f[g(x)] means to replace the x of function f(x) with function g(x)
Given:
f(x) = 3x + 13g(x) = 3x - 1Therefore:
f[g(x)] = 3[g(x)] + 13

Because when you distribute 2(x+3)=20 turns to 2x+6=20 and 2x+6≠2x+3

A solution to -x + 10 = 2x + 4 is 8
Answers
Answer:
False.
Step-by-step explanation:
What is the question if you have the solution already?
I guess its a true/false question. In that case it's false because:
-x + 10 = 2x + 4
-x -2x + 10 = 4
-x - 2x = 4 - 10
-3x = -6
x = - 6 / -3
x = 2
Answer:
False.
This equation has only one solution, and it is x = 2.
Step-by-step explanation:
-x + 10 = 2x + 4
Subtract 2x from both sides.
-3x + 10 = 4
Subtract 10 from both sides.
-3x = -6
Divide both sides by -3.
x = 2
False.

The answer is 35.5 square units
Step-by-step explanation:
The shape represents a rectangle, a small triangle removed from it at the upper right corner and a bigger triangle is attached to it at the upper left corner.
We get this formula:
A(shape) = A(rectangle) - A(small triangle) + A(big triangle)
SO LET'S FIND EACH!
A(rectangle)= length x width
length= 8 units
width= 4 units
We get:
A(rectangle) =8x4= 32 square unit
A(small triangle)= (base x height)/2
base= 1 unit
height= 1 unit
We get:
A(small triangle) = (1x1)/2 = 1/2 = 0.5 square units
A(big triangle)= (base x height)/2
base= 2 units
height= 4units
We get:
A(big triangle)= (2x4)/2 = 8/2 = 4 square units
For the final result:
A(shape) = 32 - 0.5 + 4 = 35.5 square units
In an AP* Stats class, 57% of students eat breakfast in the morning and 80% of students floss their teeth. Forty-six percent of students eat breakfast and also floss their teeth. What is the probability that a student from this class eats breakfast but does not floss their teeth
Answers
Answer:
The probability that a student from this class eats breakfast but does not floss their teeth is .11 (11%).
Step-by-step explanation:
Let's start by making a two-way table (you can also make a tree diagram).
Let's make the total number of students = 100. Now, fill out the table using the given probabilities from the question.
We are given that 57% of students eat breakfast in the morning, so the total in the "Eats breakfast" column is 57.
80% of the students floss their teeth, so the total in the "Flosses teeth" row is 80.
We can fill out the rest of the table using simple algebra and the fact that the probabilities must add up to 1.
I've attached a table that I created showing what the two-way table should look like when filled out completely.
Now, we want to find the probability that a student eats breakfast but does not floss their teeth.
We can look at the column "Eats breakfast" and the row "Does not floss teeth" and see that 11 (out of 100) students eat breakfast without flossing their teeth.
Therefore, the probability that a student from this class eats breakfast without flossing their teeth is .11.

What is the value of x is the solution to the equation -8(x + 3) = -10x - 5?
Answers
Answer:
x = 19/2
Step-by-step explanation:
1) Distribute
-8x-24=-10x-5
2) Add 24 to both sides
-8x-24+24=-10x-5+24
3) Simplify
- Add the numbers
-8x = -10x - 5 + 24
- Add the numbers
-8x = -10x+19
4) Add 10x to both sides
-8x+10x=-10x+19+10x
5) Simplify
- Combine like terms
2x = -10x+19+10x
-Combine like terms
2x=19
6) Divide both sides by the same factor
2x/2 = 19/2
7) Simplify
- Cancel terms that are in both the numerator and denominator
x = 19/2
