28a⁴b: 2 · 2 · 7 · a · a · a · a · b
16ab: 2 · 2 · 2 · 2 · a · b
GCF(28a⁴b, 16ab) = 4ab
The answer is A.
On-proportional linear relationships can be expressed in
the form y = mx + b, where b is not 0, m represents the constant rate of change
or slope of the line, and b represents the y-intercept. The graph of a non-proportional
linear relationship is a straight line that does not pass through the origin.
Step-by-step explanation:
7 1/2 = 7 + 1/2 = 14/2 + 1/2 = 15/2 = 7.5

Cosine(angle) = adjacent leg/ hypotenuse
Cosine( angle ) = 18/20
Angle = arccos(18/20)
Angle = 26 degrees
