Answer: 1
--------------------------------------------------------------
The equation y = 1*sin(2x) is in the form y = a*sin(bx-c)+d
where
a = 1
b = 2
c = 0
d = 0
The value of 'a' determines the amplitude
amplitude = |a| = |1| = 1
49×12= 588
1. 50×10=500
2. 50×10+2= 502
3. 50×12-12= 588
4. 50+12-12=50
Another way to write 49×12 is 50×12-12
|2.5| because 2 and 1/2 are also 2.5 written in decimal, and the absolute value is always positive
C because the relation acts as a function no mater the 2 items
Remember when solving inequalities the sign of your inequality reverses when dividing or multiplying negative values. k/-12<15. k>-180 [-180, positive infinity)
