The formula is
L = rC where L = length of the arc, r = radius of the circle and C is the angle in radians.
here r = 4 and C = 110pi / 180
arc length L = (4 * 110 * pi) / 180 = 7.7 ins
A function should produce one output for one given input.
Therefore a function should pass the vertical line test.
From the figure,
a,b,c pass the vertical line test;
d fails the vertical line test.
Answer: Case d does not represent a function.
First, write an equation system for the problem
For example, x represents the first angle and y represents the second angle
An equation for "t<span>he measure of an angle is seventeen times the measure of a complementary angle" is
</span>∴ <span>x = 17y
The sum of complementary angle is 90</span>°. It can be written as<span>
</span>∴ x + y = 90°
<span>
Second, use subtitution method to find the value of x and y
Subtitute x with 17y
x + y = 90</span>°
17y + y = 90°
18y = 90°
y = 90°/18
y = 5°
Subtitute y with 5°
x = 17y
x = 17(5)
x = 85°
The measure of each angle is 5° and 85°
First, you put each fraction into its greatest common denominator:
5/20 - 12/20. This then gives you the answer - 7/20.
