Given:
Central angle =
Arc length = 1.5 in
To find:
The radius of the circle.
Solution:
We know that the formula for arc length is
Where r is radius and is the central angle in radian.
Substitute the given values in the above formula.
On further simplifiation, we get
Therefore, the radius of the circle is 1.91 in.
We have been given that the number of species of coastal dune plants in Australia decreases as the latitude, in °s, increases.
Further we know that there are 34 species at 11°s and 26 species at 44°s.
We can express the given information at two ordered pairs as shown below:
Let us find slope of the line through these points:
Therefore, we can write the equation of line in slope intercept form as:
Where b is the y intercept, and we can find its value using one of the two points.
Therefore, the required equation of the linear function is:
