Answer:
The approximate area is A) 5.09cm²
Step-by-step explanation:
Area of a Circle = πr²
r = 1.8
Plug in our values
π(1.8cm²)
Evaluate the area of the entire circle
a = π(1.8cm²)
a = π(3.24cm)
a = 10.179cm²
Area of a sector, with the area of the circle of the sector being a = theta/360 * a
Evaluate the area of the sector
180/360*10.719cm²
0.5 * 10.179cm²
5.0895cm²
Round the value up
5.09cm²
Answer:
80%
Step-by-step explanation:
Percentile rank = (number of scores lower or equal to 82 / total number of scores) * 100%
Percentile = (8 / 10) * 100%
= 0.8 * 100%
= 80%
Answer:
The equation of the line that is parallel to is and the equation of the line that is perpendicular to is .
Let be a line whose equation is:
(1)
Whose explicit form is:
(2)
Where:
- Independent variable.
- Dependent variable.
The slope and x-intercept of the line are and , respectively.
There are two facts:
A line is parallel to other line when the former has the same slope of the latter.
A line is perpendicular to other line when the former has a slope described the following form (), where is the slope of the former.
Then, the equation of the line that is parallel to is and the equation of the line that is perpendicular to is .
