Answer:

(x - $\frac{5}{2}$ )² + $\frac{7}{4}$

Step-by-step explanation:

x² - 5x + 8

Using the method of completing the square

add/subtract ( half the coefficient of the x- term )² to x² - 5x

x² + 2(- $\frac{5}{2}$ )x + $\frac{25}{4}$ - $\frac{25}{4}$ + 8

= (x - $\frac{5}{2}$ )² - $\frac{25}{4}$ + $\frac{32}{4}$

= (x - $\frac{5}{2}$ )² + $\frac{7}{4}$

What strategy would you use to find a vertex on a graph, on a table or of an equation? How are these strategies different?

Gemiola [76]

Hey there! :D

To find a vertex on a graph, you would need to look at where the line stops. This place where there is a distinct curve or stopping point and at least one line is going infinity in one direction is the vertex. The graph is much easier than any other method, because it is visual. If I was looking at the vertex on a table, I would see (especially on a quadratic) if there was a pattern to the points. Most points are opposite of each other, so it can be helpful to look at a pattern. In an equation, a parent function can help to see where the vertex is, as well (for quadratics) finding the line of symmetry with the equation to find the vertex. (-b/2a) The strategies are very different, some are easier than others. For example, I would much rather look at a graph for a vertex then do an equation to find it. Some involve looking, seeing a pattern, and others solving. They are all very different but can all be extremely helpful!

I hope this helps!

Is -2.9 a rational or integer or whole or natural number

Burka [1]

Answer:

Step-by-step explanation:

It might help to get artsy/crafty with this. I made it out of construction paper, but I'm going to tell you how to draw it.

Draw a large circle, over have the page. Every number, ever, even the numbers in the smaller circles, go into this circle, fractions, decimals, negatives, zero, whole numbers, every number. Negative infinity to positive infinity and everything in between. These are rational numbers.

Now draw a smaller circle inside that one. In the smaller circle there are positive and negative numbers, but no fractions. Every number in this circle is also in the larger circle, but not every number in the bigger circle in in this smaller one. Negative infinity to positive infinity, no fractions. These are integers.

Draw a smaller circle inside the smaller one. No negative numbers in this one, only positive numbers and zero. 0 to infinity, no fractions. These are whole numbers.

One more circle inside the smallest one. Only positive whole numbers in here. No zero. 1 to infinity, no fractions. These are natural numbers.

-2.9 is negative and decimal, so not a natural, not a whole, not an integer. That leaves rational.
