Find the area for the given circle. Round to the nearest tenth.

113.0 ft^2
124.8 ft^2
37.7 ft^2
452.2 ft^2

Answers

Answer:

The answer is 113.0 ft^2

Step-by-step explanation:

To find the area you do pi times the radius squared, so that would be pi times 36. which equals 113.0 ft^2.

The area of a given circle is 113.0 square feet. Therefore, option A is the correct answer.

What is area of a circle?

The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.

Given that, the diameter of circle is 12 feet.

Here, radius = 12/2

= 6 feet

Now, area of a circle = 3.14×6²

= 3.14×36

= 113.0 square feet

Therefore, option A is the correct answer.

F(x)=bx^2+32 For the function f defined above, b is a constant and f(2)=40. What is the value of f(-2)?

Answers

Answer:

f(-2) = 0

Step-by-step explanation:

Given that:

f(x) = bx^2 + 32

f(2) = b(2)^2 + 32

f(2) = 4b + 32

f(2) = 4b = -32

f(2) = b = -32/4

f(2) = b = -8

Thus;

f(-2) = -8(-2)^2 + 32

f(-2) = -8(4) + 32

f(-2) = -32 + 32

f(-2) = 0

Solve Using Substitution
-9x + 6y = 18
y = -6​

Answers

Answer:

the answer should be x = -6

Step-by-step explanation:

-9x + 6y = 18

-9x + 6(-6) = 18

-9x - 36 = 18

-9x - 36 + 36 = 18 + 36

-9x = 54

-9x ÷ -9 = 54 ÷ -9

x = -6

Step-by-step explanation:

Simplify both sides of the equation.

3(−x+2x+1)=x−1

Distribute

(3)(−x)+(3)(2x)+(3)(1)=x+−1

−3x+6x+3=x+−1

Combine Like Terms

(−3x+6x)+(3)=x−1

3x+3=x−1

3x+3=x−1

Subtract x from both sides.

3x+3−x=x−1−x

2x+3=−1

Subtract 3 from both sides.

2x+3−3=−1−3

2x=−4

Divide both sides by 2.

What does it mean for a point to be a solution to a linear equation?

For example, if I say, "(2,5) is a solution to the equation (y=2x+3)," how could you check my claim?

Answers

Answer:

In your equation y=2x+3 and you used 2 [from your point (2,5) ] as the value of x, then y=2(2)+3=7.

now if you plotted this, that point would be (2,7), not (2,5).

So (2,5) is not the solution.

(2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].

Let be linear equation [tex]y = 2\cdot x + 3[/tex], if we know that [tex](x,y) = (2, 5)[/tex] and we need to check is [tex]2\cdot x + 3 = 5[/tex] by algebraic means, that is, we solve for [tex]x[/tex]:

[tex]2\cdot x + 3 = 5[/tex]

[tex]2\cdot x = 2[/tex]

[tex]x = 1[/tex]

Hence, we conclude that (2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].

The old bag of marbles contains 4 blue and 3 red marbles. If you were to double the number of red and blue marbles to create a NEW bag, would the chance of pulling out a blue marble be the same as pulling a blue marble from the old bag? (this is for math class by the way-)

Answers

Answer:

The chance will be the same (4/7)

Step-by-step explanation:

Old bag

p(blue)=4/7

New bag

p(blue)=8/14=4/7

The chance will be the same (4/7) since both the red and the blue marbles are doubled at the same time implying that the ration of red to blue still remails the same.
