<span>The area to be determined is a segment of the circle.
Since central angle is 120 degrees and 120/360 = 1/3
area of sector of circle is (1/3)*36pi = 12pi
For the area of triangle, you can split it into 2 30-60-90 right triangles with sides 3:3sqrt3:6
thus base of triangle is 6sqrt3 and height is 3
Area = 1/2 * 3* 6sqrt3 = 9sqrt3 -->
segment area = 12pi - 9sqrt3</span>
Answer:
5
Step-by-step explanation:
Factors of 35: 1,5,7,35
Factors of 10: 1,2,5,10
5 is the greatest common factor.
Answer:
4x4 - x3 + 7x2 + 13x - 10
Step-by-step explanation:
(((4•(x4))+7x2)+6x)-(x3-7x+10)
((22x4 + 7x2) + 6x) - (x3 - 7x + 10)
3.1 Find roots (zeroes) of : F(x) = 4x4-x3+7x2+13x-10
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is -10.
of the Leading Coefficient : 1,2 ,4
of the Trailing Constant : 1 ,2 ,5 ,10
Final result :
4x4 - x3 + 7x2 + 13x - 10
hope this helps:)sorry if it doesnt
15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
