The cofunction of cos is sin(90-x)
90 degrees is equal to PI/2
The cofunction becomes sin(PI/2 - 2PI/9)
Rewrite both fractions to have a common denominator:
PI/2 = 9PI/18
2PI/9 = 4PI/18
Now you have sin(9PI/18 - 4PI/18)
Simplify:
Sin(5PI/18)
Raj’s bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. The table shows that the amount of water remaining in the bathtub, y, is a function of the time in minutes, x, that it has been draining.
What is the range of this function?
all real numbers such that y ≤ 40
all real numbers such that y ≥ 0
all real numbers such that 0 ≤ y ≤ 40
all real numbers such that 37.75 ≤ y ≤ 40
Answer:
The answer would be 16
Step-by-step explanation:
The answer would be 16 because after each number your subtracting 3.
