Answer:
A group of students formed a circle during a game.The circumference of the circle was about 43.96 feet,and the diameter of the circle was 14 feet.Which expression best represents the value of π?
The expression which represents the value of π is option C from the attachment that is π = 43.96/14
Step-by-step explanation:
Given:
Circumference of the circle = 43.96 feet
Diameter f the circle = 14 feet
So,
We know that :
Circumference of the circle = 
or 
Re-arranging the formula:
⇒ 
⇒ 
⇒ 
⇒ 
Plugging the numeric values:
⇒ 
So the expression for π is 43.96/ 14,and option C is the correct choice.
Answer:
see explanation
Step-by-step explanation:
y = 1 is the equation of a horizontal line parallel to the x- axis.
Since it is parallel to the x- axis then its slope is zero.
A line perpendicular to it will therefore be a vertical line parallel to the y- axis.
The slope of the perpendicular line is undefined.
The slope of a parallel line is zero
Answer:
if the two lines have the same slope that means they are parallel
Factors are the numbers you multiply together to get given number.
All possible factorizations of number 18 by two factors are:
- 18=1·18;
- 18=2·9;
- 18=3·6.
Answer: 1 and 18, 2 and 9, 3 and 6.
Given:
The inequality is:
To find:
The y-intercept, slope and type of line (solid or dotted).
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope and b is the y-intercept.
We have,
The relation equation is:
...(ii)
On comparing (i) and (ii), we get
It means the slope is 5 and the y-intercept is 3.
The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.
Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.
