The average rate over ![[2,b]](https://tex.z-dn.net/?f=%5B2%2Cb%5D)
Average rate (m) is calculated using:
Where
![[a,b] = [2,b]](https://tex.z-dn.net/?f=%5Ba%2Cb%5D%20%3D%20%5B2%2Cb%5D)
So, we have:
Calculate f(b) and f(2)
So, we have:
Expand the numerator
Factorize
Factor out 3b + 6
Cancel out b - 2
The second one is correct
Answer/Step-by-step explanation:
Given:
m<A = 115,
m<B = 78,
m<C = 35,
✔️m<1 = 180 - m<A (angles on a straight line/supplementary angles)
m<1 = 180 - 115 (substitution)
m<1 = 65°
✔️m<2 + m<1 + m<B = 180° (sum of interior angles of a triangle)
m<2 + 65 + 78 = 180
m<2 + 143 = 180
m<2 = 180 - 143 (substitution property of equality)
m<2 = 37°
✔️m<3 = 180° - m<B (supplementary angles)
m<3 = 180 - 78
m<3 = 102°
Answer:
a= 40
area=length*width
