Answer:

Step-by-step explanation:

Since polynomial long division is a pain to explain in words, here's a nice trick for problems where you know the answer has no remainder and you are dividing a polynomial by any x-a where x has a coefficient of 1.

The first term of the quotient will be the first term of the dividend lowered by one power, and any constant at the end of the dividend will end up as a constant at the end of the quotient, where the final constant is the first constant/-a. With this trick you can shortcut your way to the answer. Since the quotient must start with 3 $x^{4}$ and end with +5, D must be the answer.

The graph of Y=|x| is transformed as shown in the graph below. Which equation represents the transformed function?

MrMuchimi

Answer:

Step-by-step explanation:

The first thing you need to do is find the slope. Find two perfect points.

In this case I chose (0,0) and (4,1). Slope is basically rise over run. In other words, how much you go up, and how much you go right. We rise up one and to the right 4.

Answer:

$\bold{Q13}\ \angle W\\\\\bold{Q14}\ \angle S\\\\\bold{Q15}\ side\ WA\\\\\bold{Q16}\ \triangle PTA$

Step-by-step explanation:

For Q13, Q14, Q15

$\text{for}\ \overline{WA}\ \text{and}\ \overline{AS}\ -\ A\ \text{is common}.\ \text{Therefore inclu}\text{ded angle is}\ \angle A\\\\\text{for}\ \overline{WS}\ \text{and}\ \overline{WA}\to\angle W\\\\\text{for}\ \overline{WS}\ \text{and}\ \overline{SA}\to\angle S\\\\============================$

$\text{Inc}\text{lude side between}\ \angle A\ \text{and}\ \angle W\ \text{is}\ AW\ (WA).\\\\\text{Inc}\text{lude side between}\ \angle S\ \text{and}\ \angle W\ \text{is}\ SW\ (WS).\\\\\text{Inc}\text{lude side between}\ \angle A\ \text{and}\ \angle S\ \text{is}\ AS\ (SA).$

Q16

$O\ \leftrightarrow\ T\\B\ \leftrightarrow\ A\\R\ \leftrightarrow\ P\\\\\text{Therefore}\ \triangle ROB\ \cong\ \triangle PTA$

Explain if the combination of iron and copper sulfate is an example of a chemical reaction

zysi [14]

Answer:

Yes it is.

Step-by-step explanation:

When we mix Fe(iron) to CuSO⁴ (Copper sulphate), Iron removes copper from CuSO⁴ and makes FeSO⁴. This happens because iron is more reactive than copper. We cannot remove iron from this solution now until any stronger element is added.
