The axis of symmetry of a parabola in the form
is a vertical line
where k is the x coordinate of the vertex of the parabola.
The x coordinate of the vertex of the parabola is given by
which in your case is
So, the axis of symmetry is the line x=12.
Let the both the parts be 'x' and 'y'
x>y
We know that 4x = 5y
so x = 5y/4
x + y = 54
Replacing x we get
(5y/4) + y = 54
(5y +4y)/4 = 54
9y = 216
y = 24
Replacing y in ' x+y = 54'
we get x = 30
Hence the larger part is 30 whereas the smaller part is 24
The rule would be : 3^x, where x starts at 0.
3^0 is 1,
3^1 is 3, because 3 one time is 3.
3^2 is 9, because 3x3 is 9.
3^3 is 27, because 3x3x3 is 27
Answer: 3^x
Sol_
( 3 - 2 ) + ( 4 - 1 ) ^ 2
= 1 + 3^2
= 1 + 9
= 10
Answer is " - " .
hope it helped !
Thanks!
8 + 3(16-12)
8 + 3(4)
8 + 12
20 is your answer
hope this helps
