I think it is c I really don't understand
Answer:
B
Step-by-step explanation:
B*H= Area of a Triangle
Substitute:
Answer:
52 in Squared (D)
the answer is negativepositive
2x+5=11
2x=11-5
2x=6
x=6:2
x=3
Note that the sine function always produces values between -1 and 1.
π in sin(x-π) only shifts the graph of sin(x) horizontally, having no effect on the range, which still is [-1, 1].
Multiplying by 2 (we have 2sin(x-π) ), means that the new range is [-2, 2].
Last, adding 1, means that all the values taken by 2sin(x-π), that is [-2, 2], are now one unit higher in the graphs.
This means that the range is [-2+1, 2+1]=[-1, 3].
Answer: D: [-1, 3]
