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
Answer:
All you need to do is to calculate the perimeter of the circle since you already had the diameter
Base on the picture, the perimeter should be:
C = d * π = 64 * 3.14 = 200.96 (m)
ANSWER
A. No because f(c)=-30
EXPLANATION
The given polynomial is
If x+1 is a factor , then f(-1) must evaluate to zero.
Since f(-1) is not equal to zero, x+1 is not a factor of
Simply multiply 45 by 2 and you get your answer which is 90 cookies
