Sin(225)
225 degrees is in the 3rd quadrant. And in the third quadrant only tangent is positive, sin is negative.
For third quadrant, basic angle = 225 - 180 = 45
sin225 = - sin45
sin225 = - sin45 = -0.7071
sin 225° ≈ -0.7071
Rationalize both the numerator and denominator. Given

we can rationalize it by introducing conjugates of the numerator and denominator:

Then the limit is equivalent to

For the remaining expression, divide through uniformly by
:

As <em>n</em> goes to infinity, the remaining terms containing <em>n</em> converge to 0, leaving

making the overall limit 3.
Answer:
y=(0.1)x and y=2(1/4)x represent exponential decay
the rest all are an equation used for exponential growth
Answer:
The possible graph is "A". A further explanation is given below.
Step-by-step explanation:
The given values are:
Dominick spends on running
= 0.70 hours
He spends on swimming
= 1.5 hours
This week,
Dominick spends more than six hours.
If,
Number of runs be "x".
Number of swimming be "y".
then,
⇒ 
⇒ 
⇒ 
Therefore, 
x = 0
y = 4
So the above is the correct answer.
