Answer: A) moves two places to the right
Example:
![2.567 * 10^2 = 2.567 * 100 = 256.7](https://tex.z-dn.net/?f=2.567%20%2A%2010%5E2%20%3D%202.567%20%2A%20100%20%3D%20256.7)
The positive exponent over the 10 tells us how many places to move to the right. If the exponent was negative, then we'd move to the left. This only works when the base is 10.
Answer:
By Side-Side-Side (SSS) property, CA = CB
Step-by-step explanation:
Given: /AB/ and bisector /CD/.
Proof: CA = CB
But,
AD = BD (since D is the midpoint of AB)
<CDA = CDB (right angle property)
<CAD = CBA (congruent property of triangles)
Therefore;
Δ ACD = ΔBCD (congruence property)
=
(proportion of the sides of two congruent triangles)
Thus, by Side-Side-Side (SSS) property, CA = CB
Answer:
The product to this problem is simplified to: ![1+14f+49f^{2}](https://tex.z-dn.net/?f=1%2B14f%2B49f%5E%7B2%7D)
Step-by-step explanation:
1) First place out what was given:
![(-1 -7f)^{2}](https://tex.z-dn.net/?f=%28-1%20-7f%29%5E%7B2%7D)
Squared is the same thing as multiply to itself, so you would create a pair of
(For example, if you said:
it is the same as saying or putting: x · x)
2) Then create your pair which would look like:
![(-1 -7f)(-1 -7f)](https://tex.z-dn.net/?f=%28-1%20-7f%29%28-1%20-7f%29)
3) Next step is to do the FOIL method
<h2>(The <u><em>FOIL</em></u> method is where you do <em><u>F</u></em>irst, <em><u>O</u></em>utside, <em><u>I</u></em>nside, an <u><em>L</em></u>ast)</h2>
(Like how it is shown in the picture, we will do this method and create one whole expression!)
4) Creating and combining your expression into one whole problem, by using the foil method.
![(-1 -7f)(-1 -7f)](https://tex.z-dn.net/?f=%28-1%20-7f%29%28-1%20-7f%29)
First - F: ![1](https://tex.z-dn.net/?f=1)
Outside - O: ![7f](https://tex.z-dn.net/?f=7f)
Inside - I: ![7f](https://tex.z-dn.net/?f=7f)
Last: ![49f^{2}](https://tex.z-dn.net/?f=49f%5E%7B2%7D)
This will be:
![1+14f+49f^{2}](https://tex.z-dn.net/?f=1%2B14f%2B49f%5E%7B2%7D)
And this will be your answer!
The answer is A. Hope u get it right
