PLEASE HELP ASAP!!
Mark Is using a string attached to a stick to mark off a circular-shaped flowerbed In his garden. If the circumference of
the flowerbed Is 31.4 feet, how long was the string he used? That is, how long is the radius of the circle? (Use 3.14 for 17.)
A. 10 ft
B. 3.2 ft
C. 5 ft
D. 100 ft
Answers
Answer:
C
Step-by-step explanation:
Hey There so the first step of this problem is to find the formula for circumference
[tex]C=2\pi r[/tex]
given some of the values we can form an equation to solve for the radius (r)
[tex]31.4=3.14(2)r\\3.14(2)=6.28\\31.4=6.28r\\\frac{31.4}{6.28} =5[/tex]
so we can conclude that the radius is equal to 5
Answer:
C) 5 ft
Step-by-step explanation:
Equation used: C=2πr
This isn't a hard question once you understand the basics of it. The radius squared by 2 equals the diameter, and other way around. Your going to divide the circumference by the pie (π).
31.4 ÷ 3.14 = 10
Now you'll do 10/2 to equal 5.

y = -3x - 1/9
Step-by-step explanation:
general formula I believe you are saying so y = mx+b
(8, -4) , (6, 2)
plug this into y2-y1/x2-x1
2 -(-4)/ 6-8 = 6/-2 = -3
-3 equals the slope
then plug into the next equation to find the y-int. (b)
2 = -3(6) + b
2/-18 = -18/-18 + b
-1/9 = b
y = -3x - 1/9

Answers
Answer:
-86x^2 -2x - 8
Step-by-step explanation:
The solution is:
6x²+2x²+3x-4x-9+1 becomes 8x²- x -8.
What is Subtraction?Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.
Here, we have,
Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).
To subtract -2x^2+4x-1 from 6x^2+3x-9,
that is
6x^2+3x-9 - (-2x^2+4x-1).
This can be written as
6x²+3x-9 - (-2x²+4x-1)
Now, opening the bracket, we will get
6x²+3x-9 +2x²-4x+1
Then, collecting like terms, we get
6x²+2x²+3x-4x-9+1
6x²+2x² = 8x²
3x-4x = -x
-9+1 = -8
∴6x²+2x²+3x-4x-9+1 becomes 8x²-x -8
The answer is 8x²-x -8.

Answers
Answer:
(x - 24)(x + 3)
Step-by-step explanation:
Given
x² - 21x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 21)
The factors are - 24 and + 3, since
- 24 × + 3 = - 72 and - 24 + 3 = - 21 , then
x² - 21x - 72 = (x - 24)(x + 3) ← in factored form

someone help i found the slope already.
Answers
Answer:
s(x)
Step-by-step explanation:
s(x) is a linear function, so the average rate of change is its slope.
Its slope is 3.
You are correct.
To find the average rate of change of polynomial function t(x) from -2 to 2, find the values of t(x) at x = -2 and at x = 2.
average rate of change = [t(2) - t(-2)]/[2 - (-2)]
t(x) = 0.1(x^3 - x^2 + 2)
t(-2) = 0.1[(-2)^3 - (-2)^2 + 2)]
t(-2) = 0.1(-8 - 4 + 2)
t(-2) = -1
t(2) = 0.1[(2)^3 - (2)^2 + 2)]
t(2) = 0.1(8 - 4 + 2)
t(2) = 0.6
average rate of change = [t(2) - t(-2)]/[2 - (-2)]
average rate of change = [0.6 - (-1)]/4
average rate of change = 1.6/4
average rate of change = 0.4
average rate of change for s(x) = 3
average rate of change for s(x) = 0.4
Answer: s(x)

The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]
Step-by-step explanation:
The distance from (-1, 12) to (-1, 8) = 4 = diameter of the circle. So, 2 = radius
The center of the circle is at (-1, 10)
The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]
