Determine the average change
This is calculated as follows:
This gives:
Convert to improper fractions
Convert to multiplication
First simplify the equation and next multiply the 20 with the x^2 and find a number that adds together to give you the middle
Least to greatest: 2/5, 3/5, 7/10, 3/4
Step-by-step explanation:
3cos2x +sinx=1
3(1-2sin²x)+sinx=1
3-6sin²x+sinx=1
sinx(-6sinx+1)=1
either
sinx=1
sinx=sin(90)
:.x=90
or
-6sinx+1=1
-6sinx=1-1
sinx=0/-6
sinx=sin0,sin180
:.x=0,180and90
