This equals [f(3) - f(1)] / [3-1]
= 3^2 + 6(3) + 10 - (1^2 + 6(1) + 10) / 2
= (37 - 17) / 2
= 10 Answer
Answer:

Step-by-step explanation:
For this triangle we have to

We want to find the length of b
We know that the sum of the internal angles of a triangle is 180 °
So

Now we use the sine theorem to find the length of b:

Then:

Answer:
C
Step-by-step explanation:
y = 10
x = 8
The y intercept is 0 and the line runs through (0,0)
m = y / x This formula can only be used when the y incept is 0.
m = 10/8
m = 5/4
Equation
y = 5/4 x

Answer:
Step-by-step explanation:
Use the Law of Cosines
A = arccos[(10²+14²-9.6²)/(2×10×14) ≅ 43.3°
I think that is the mean or the mode . I think more on mean
