On the unit circle: the end of the terminal side of a 90 degree angle is (1,0) where 1 is the value of sin(90°) and 0 is the value of cos(90°)
On the graph of sine: 90° =
radians. if f(x) = sin(x) in radians, f(
) = 1/2
The value a = 4 will always yield a correct answer.
We know this by solving for a. If we do this, we will get the number needed.
a(x + 3) < 5x + 15 - x -----> simplify like terms
a(x + 3) < 4x + 15 -----> divide by x + 3
a < 4 + 3/(x + 3)
Since a is less than 4 plus a number, we know that a will always be less than 4. So we can use 4 as the number for all real solution.

Answer:
a_23 = 5
Step-by-step explanation:
The row is the first number so in a_23 The row is a 2
The column is the second number so the column is 3
The second row is 3 9 5 1
The third column number would be 5
The answer is a
