Answer:
'-5'
Step-by-step explanation:
The table is a linear function. This means that all the points have a consistent slope. If two points had a different slope, it would be a nonlinear function.
Slope is rise over run. We are given the points (-3,0) and (-2,-5).
so what you do is
a^2-a-20
see, the number in front of the a^2 is 1, so now we do
look at the number infront of the a and the number at the end
-1 and -20
whhat 2 numbers multiply to get -20 and add to get -1
trial and error
-20+1=-19, nope
-10+2=-8 nope
-5+4=-1, yes
(a-5)(a+4) is factored
Given:
Radius of the circle = 4 meters
Measure of arc = 135 degrees
To find:
The area of the sector bounded by the given arc.
Solution:
Formula for area of a sector is:
Where, r is the radius and is the central angle or measure of intercepted arc.
Putting in the above formula, we get
Therefore, the exact area of the given sector is square meters.
4,135 divided by 14 is 295.4
