When we are partitioning in division, we are dividing the number into its place values, and then applying the divisor to each of the values.

For example in the first problem, we have 642, which is also 600 + 40 + 2.

That means we'll have three division problems.

600 ÷ 2 = 300

40 ÷ 2 = 20

2 ÷ 2 = 1

Which means that 642 ÷ 2 = 300 + 20 + 1, or 321.

You can apply this format to the other two problems to find their answers.

If you do, you should get that 969 ÷ 3 = 323, and 844 ÷ 4 = 211.

Hope this helps!

URGENT, will reward brainliest. Explain how to find the axis of symmetry for each function, and rank the functions based on thei

kozerog [31]

The axis of symmetry of a parabola is a line that divides it into two similar halves and this axis always goes through the vertex.

To find the equation of the line that represents the symmetry of the curve, suppose a parabola of the form $y = ax ^ 2 + bx + c$

Then, deriving y with respect to x we have:

$\frac{dy}{dx} = 2ax + b$

By matching dy / dx to 0 we have and by clearing x we have:

$x = \frac{-b}{2a}$

This equation allows us to find the axis of symmetry for any quadratic function

Then for the first function of the image.

The axis of symmetry is:

$x = \frac{16}{2*2}$

$x = 4$

For the second function of the image:

$x =\frac{-(-10)}{2*5}$

$x = 1$

For the third function the axis of symmetry is observed with the naked eye, is the line of equation:

$x = -2$
