Answer:

Step-by-step explanation:

You know two sides and the angle between them. Use the Law of Cosines to find the third side.

q = √(p²+r²-2pr·cosQ) ≅ 8.533 units

Use Heron's formula to find area

semi-perimeter s = (p+q+r)/2 ≅ 10.317 units

area = √(s(s-p)(s-q)(s-r)) ≅ 16.3 units²

Part A: A graph passes through the points (0, 2), (2,6), and (3. 12). Does this graph represent a linear

allsm [11]

Answer:

The function given is non-linear.

Step-by-step explanation:

The slope between (0, 2) and (2,6):

$\frac{6-2}{2-0}=\frac{4}{2}=\boxed{2}$

The slope between (2,6), and (3, 12):

$\frac{12-6}{3-2}=\frac{6}{1}=\boxed{6}$

Since the slopes are not equal to each other, the function is non-linear. A linear function's slope must stay consistent.

Hope this helps.
