1.
Area of shaded region,
=(Area of bigger circle) - (Area of smaller circle)
=πR^2 - πr^2
=π ( R^2 - r^2 )
=3.14 ( 8^2 - 4^2)
=3.14 × ( 64 - 16 )
=3.14 × 48
=150.72 cm^2
2.
Area of shaded region,
=(Area of big semi-circle) - ( Area of small semi-circle)
=(πR^2)/2 - (πr^2)/2
=π/2 ( R^2 - r^2 )
=3.14/2 ( 6^2 - 3^2 )
=1.57 × ( 36 - 9 )
=1.57 × 27
=42.39 cm^2
HOPE THIS WILL HELP YOU
Answer:
Combining like terms is just that, combining numbers in an equation that have the same property. examples would be constants or numbers with the same exponent.
Properties of exponents are when you multiply, add, subtract, or divide exponents.
I hope I helped!
Answer:
option B
Step-by-step explanation:
First Quartile = 14
Hey there!
-4x^-2 + 3y^0
= -4(2)^-2 + 3(5)^0
= -4(1/4) + 3(5)^0
= -1 + 3(5^0)
= -1 + 3(1)
= -1 + 3
= 2
Therefore, the answer should be: 2
Good luck on your assignment and enjoy your day!

Domain:
f(x) has a denominator, which can't be zero. So, its domain is given by
g(x) has a denominator as well. Moreover, it has a root. So, the content of the root can't be negative:
And the denominator can't be zero:
So, the domain is
Composition:
We have
The domain of this function is
But we also have to remember about the domain of g(x): if g(x) is undefined, we can't compute f(g(x))!
So, the domain of f(g(x)) is
