Answer:
f(x), h(x), g(x)
Step-by-step explanation:
For a quadratic in standard form, ...
ax² +bx +c
the axis of symmetry is ...
x = -b/(2a)
For the various functions, the axes of symmetry are ...
f(x): x = 0/(2·3) = 0
g(x): x = -(-4)/(2·1) = 2
h(x): x = (-4)/(2(-2)) = 1
From least to greatest axis of symmetry the functions are ...
f(x), h(x), g(x)
Answer:
The area of the triangle is 
Step-by-step explanation:
Using the fact that the area of the triangle having u and v as adjacent sides is given by

We know that we want to take a cross product to compute the area of the triangle, but we need to be careful because it doesn't make sense if we take the cross product of points.
The first step is to build some vectors that describe this triangle.
According with the graph we can build the vectors:
and 
The vector
is the difference of point B minus point A

and the vector
is the difference of point C minus point A

Next we need to find the cross product of this vectors.

This is the definition of cross product of two vectors in space:
Let
and
be vectors in space. The cross product of
and
is the vector

Applying this definition we get



The area of the triangle is

Answer:
550
Step-by-step explanation:
To round 553 to the tens place, we would need to identify the value of the digit in the ones place.
If the digit in the ones place is greater than 5, we increase the tens place by 1 & convert the ones place into a 0.
If not, we leave the tens place as is & convert the ones place into a 0.
Since 3 is less than 5, we round 553 to 550 so you are correct.
Well that's division.
•36 divided by 9 is equal to 4.
• 81 divided by 9 is equal to 9.
•45 divided by 5 is equal to 9.
•56 divided by 7 is equal to 8.
•42 divided by 7 is equal to 6.
