Answer:
sin(x) = -sqrt2/2
tan(x) = -1
Step-by-step explanation:
Because it is between 270 and 360, sin is negative, so it is -sqrt2/2.
tan(x) is sin(x)/cos(x), so it is just -1.
Answer:
x= -1 (looks like C)
Step-by-step explanation:
To solve for x, factor the quadratic. Begin by factoring out a GCF of 5.

To factor the remaining parts of the quadratic, look for two factors of 5 which add to 6. This would be 1 and 5.
So the quadratic factored is:

To solve for x, set each factor equal to 0 and solve.
x+1 = 0
x = -1
x+5 = 0
x=-5
-1 is the largest solution.
Answer: A is the correct answer
Step-by-step explanation: D has a removable discontinuity at x =-3 and is not continuous.
