Answer:
Increases from 27 to 36
Step-by-step explanation:
The function f(x) = 9x is a linear function. It increases over the interval (-∞, ∞). It continues to increase over the interval x = 3 and x = 4. It changes from 9*3 = 27 to 9*4 = 36.
The law of cosines is:
c² = a² + b² - 2abCos(C)
Therefore, in order to apply this law, we must know the value of two adjacent sides, represented by a and b here, and the value of their subtended angle, represented by C.
<span>-(28-45)
= -28 -(-45)
=-28 + 45
= 45 - 28
= 17
