Answer:
Area of circle is 9π
Step-by-step explanation:
The area of sector of a circle is given by 
Plugging the given values in the formula, we get
Cancel out 1/2 and π from both sides, we are left with
Cross multiplying, we get
Therefore, area of circle is given by
Area of circle is 9π
Answer:
-20x+128
Step-by-step explanation:
–8(x – 4) - (12x – 8)
distribute: -8x+32-12x+96
combine like terms
-20x+128
Answer:
its 44 the answer
Step-by-step explanation:
I hope this helps
Relative extrema occur where the derivative is zero (at least for your polynomial function).
So taking the derivative we get
<span>20<span>x3</span>−3<span>x2</span>+6=0
</span><span>
This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
