1/2 x3 + 3.4y
1/2 3(2) + 3.4(5)
1/2 3X2 + 3.4X5
1/2 6 + 8.4
1/2 14.4
0.5 + 14.4
14.9
I think this is the answer. I might be wrong!
Have a great day! :D
Answer: The area is 530 square units
Step-by-step explanation: The diameter of the circle has been given as 26. That makes the radius 13, that is;
Radius = diameter/2
Radius = 26/2
Radius = 13
The area of a circle is derived by the formula;
Area = pi x r^2
Where pi is 3.14 and r is 13,
Area = (3.14) x 13^2
Area = 3.14 x 169
Area = 530.66
Approximately to the nearest hundred of a square unit,
The area of the circle is 530 square units
Step-by-step explanation:
L.H.S=(1-cosB)(1+cosB)
=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}
=sin^2B
=1/cosec^2B
Therefore,L.H.S=R.H.S proved
Answer:
Union and Intersection
Step-by-step explanation:
We know that the algebra of sets define the properties and laws of the sets.
The basic operations of sets are,
Union, Intersection, Complement of a set and Equality of sets.
Since, the operations addition, subtraction, multiplication and division are the basic arithmetic operations of numbers.
i.e. they are not in the algebra of sets.
So, we get that out of the given options, the operations in algebra of sets are Union and Intersection.
