Addmaths paper 1

Wasn't there only one answer of that one?

I meant the answer for one of the questions. Will they accept my working?

 

[emmadvilla97]

Yeah but I was getting a value which wasn't applicable and then I got stuck. So I put in random digits till I got the answer

There was only one answer 2. That was given in the question's first part.

 

[emmadvilla97]

I meant the answer for one of the questions. Will they accept my working?

probably

 

[Snowysangel]

There was only one answer 2. That was given in the question's first part.

There was obviously one answer...you can't put two values in the calculstor for that function and get the same answer. My value turned out to be correct, but I found it using trial and error. I solved the question half way through and then applied it, but I didn't end up getting the value, I plugged it into the equation that I formed...will they cut a mark if I did that

One factor was given. that was the only answer

 

[Snowysangel]

One factor was given. that was the only answer

I only got one answer! But I used trial and error to get it. Are u sure u know which question I'm talking about brw :S

 

[Snowysangel]

One factor was given. that was the only answer

For the factors...there were three answers

 

[KWIKIW]

Only one.

 

[Saad Mughal]

For the factors...there were three answers

There was only one REAL root to the function.

 

[KWIKIW]

Only one answer, right?

 

[Saad Mughal]

Yeah one answer and the other mark was for using any proper method of showing this.

 

[Snowysangel]

There was only one REAL root to the function.

You had to use the quadratic formula to find the other roots :S

 

[Snowysangel]

How could there be only one answer when there was a quadratic equation right there? B2-4ac was greater than o so it had to have more than 1 real roots

 

[mohdumar]

You had to use the quadratic formula to find the other roots :S

was less than zero

 

[Snowysangel]

I think I made the value of c negative when I put it in the equation so I got 3 roots...they'll cut a mark for that? My working was right tho, other than that flip in sign :/

 

[Snowysangel]

If I used trial and error in the binomial question, will they cut marks for that too?

 

[emmadvilla97]

If I used trial and error in the binomial question, will they cut marks for that too?

yeah. You had to show the working. A marks are dependant on M marks. Answer was 10.

 

[Snowysangel]

yeah. You had to show the working. A marks are dependant on M marks. Answer was 10.

I put my x2 values together and then plugged in values. So how many marks will they cut?

 

[emmadvilla97]

I put my x2 values together and then plugged in values. So how many marks will they cut?

you will probably get the M and A mark for putting the x^2 values

 

[Snowysangel]

you will probably get the M and A mark for putting the x^2 values

What are the M and A marks? How many marks will they cut?
