If a circle has a radius of 2.7 meters, what is its circumference
rounded to the nearest meter?
Answer:
17 meters
Step-by-step explanation:
the circumference is solved by multiplying the diameter by pi.
the diameter can be found by multiplying the raduis by 2
the diameter is 5.4
5.4 x 3.14
16.956
about 17 meters
Answer:
17[tex]m^{2}[/tex]
Step-by-step explanation:
The cirfumference of a circle when given the radius is 2πr
So pi is 3.14 thus:
2 × 3.14 × 2.7
16.956 [tex]m^{2}[/tex]
When rounding of to the nearest meter check if the number in the tenths side is bigger than 5. It is bigger so we add 1 to the units making it 17[tex]m^{2}[/tex].

A line passes through the points (0,3), (4,1) and (6,0). Which function best represents the relationship between the two points?
Answer:
y = - [tex]\frac{1}{2}[/tex] x + 3
Step-by-step explanation:
y = mx + b
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex] and "b" is y-intercept with coordinates (0, b)
(0, 3) ⇒ b = 3
(4, 1), (6, 0)
m = [tex]\frac{0-1}{6-4}[/tex] = - [tex]\frac{1}{2}[/tex]
y = - [tex]\frac{1}{2}[/tex] x + 3
what is the y-intercept of (5,8) and (12,36)
Answer:
The y intercept is (0,-12)
Step-by-step explanation:
You use the slope formula and the slope-intercept form to find the slope m and then the y intercept b.
Answer:
(0, -12)
Step-by-step explanation:
In order to find the y-intercept of the equation y = mx + b ( where m is the slope and b is the y-intercept), we first have to find the slope. We can do this by using the two points given to us.
To find the slope:
The slope is equal to: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's plug (5,8) and (12,36) into the equation:
[tex]\frac{36 - 8}{12 - 5}[/tex]
Now let's solve for the slope:
36 -8 = 28
12 - 5 = 7
So we get: [tex]\frac{28}{7}[/tex]
Now that we've found the value of the slope, we can put it into the equation:
y = [tex]\frac{28}{7}[/tex]x + b
To find the value of b, we can input the values of one of the given points into the equation and solve for b. Let's use (5,8):
Input the values of x and y into the equation: 8 = [tex]\frac{28}{7}[/tex](5) + b
Multiple [tex]\frac{28}{7}[/tex] by 5: 8 = [tex]\frac{140}{7}[/tex] + b
Divide 140 by 7: 8 = 20 + b
Subtract 20 from both sides of the equation to isolate b:
8 - 20 = 20 - 20 + b
-12 = b
The y-intercept is (0, -12).

What inequality is shown in the graph below?
Answer:
x > 2
Step-by-step explanation:
From the graph attached,
Given dotted line represents x = 2.
Since, given line is a dotted line, inequality represented by the dotted line will have the sign of greater than or less than (< or >) only.
Since, shaded region is on the right side of the dotted line shaded region will be represented by the inequality x > 2

You have 5814 meters of rope you need to cut into 27 sections how many 27 meters secton of rope will you be able to create and how much rope will be left over as waste
Answer:
215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left
Step-by-step explanation:
we have 5,814 meters of rope and we are told to calculate the number of 27 meters sections that we can cut:
you have to divide 5,814 meters by 27 meters = 215.333
that means that you have 215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left (0.333 x 27 = 9)

What is the slope of the line given, f(0) = -5 and f(4) = 11?
Answer:
The slope is 4.
Step-by-step explanation:
We are given that f(0)=-5 and f(4)=11.
This means that we have the two points (0, -5) and (4, 11).
So, we can use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (0, -5) be (x₁, y₁) and let (4, 11) be (x₂, y₂). Substitute appropriately:
[tex]m=\frac{11-(-5)}{4-0}[/tex]
Evaluate:
[tex]m=\frac{16}{4}=4[/tex]
Hence, the slope of the line given f(0)=-5 and f(4)=11 is 4.
