Answer:
<em>(2·4)² = 64 / (6*2)² = 144</em>
Step-by-step explanation:
Follow PEMDAS :
Parenthesis first, so:
2 * 4
==> 8
Then Exponent:
8 ^2
==> 64
(2·4)² = 64
Do the same for (6:2)² :
Parenthesis first :
6 * 2
==> 12
Then Exponent:
12^2
==> 144
(6:2)² = 144
Yo sup??
0.000000001=1*10^(-9)
since the power is (-9) hence it's called as a nano second.
This is also known as 'One nano second'
Hope this helps.
Set up a proportion, 20 over 25% and x over 60% and the answer is 48
Don't repost. be patient and we will answer
so
remember some stuff
to find the axis of symmetry of y=ax^2+bx+c
the axis of symmetry is x=-b/(2a)
that is also the x value of the vertex
to get the y value of the vertex, sub the x value of the vertex into the function
and if a is positive, then the parabola opens up and the vertex is a minimum
if a is negative, parabola opens down and vertex is max
so
y=3x^2-6x+4
3 is positive so vertex is a minimum
axis of symmetry is -(-6)/(2*3)=6/6=1
x=1 is axis of symmetry and x value of vertex
sub to find y
y=3(1)^2-6(1)+4
y=3(1)-6+4
y=3-2
y=1
axis of symmetry is x=1
vertex is (1,1)
it is a minimum
the parabola opens up
