Answer:

998796

Step-by-step explanation:

For a number to be divisible by 12. it must be divisible by 3 and 4

Since we need the largest 6 digit number, we will take x = 9

So the number is 9987yz

Again since we need the largest number we will consider the largest 2 digit number multiple of 4 and 3.

Largest 2 digit number divisible by 4 is 96, which is also divisible by 3.

So, yz = 96

Therefore , the largest number in the form will be : 998796

Answer:

The largest number is 998796

------------------------------------------------------

The largest digit you could use is 9 so, our number would be, 998799,

but the thing is that it's not divisible by 12.

The next largest would be 8. (998798) Not divisible.

7, so our number would be, 998797. Not divisible.

6, 998796. 998796/12= 83233, which means that it is divisble, so, the largest number in the form x987yz that is divisble by 12 is 998796

Please correct me if I'm wrong.

butalik [34]

Step-by-step explanation:

sinx+sin(x+4x) =cot2x
sinx+sinx cos4x+cosx sin4x=cot2x

sinx+sinx cos4x=sinx (1+cos4x) =

sinx (1-1+2(cos2x)^2) =2sinx (cos2x)^2

sin4x=2sin2xcos2x

2sinx(cos2x)^2+cosx+2sin2xcos2x=cot2x

2sinxcos2x(cos2x+2(cosx)^2)=cot2x

but 2(cosx)^2=cos2x+1

2sinxcos2x(cos2x+cos2x+1)=cos2x/sin2x

(2sinxsin2x)(2cos2x+1) =1

(4cosx(sinx)^2)(2cos2x+1) =1

Answer:

r = 3/2

Step-by-step explanation:

ratio (r) is the number that, when multiplied by the previous (n-1) term, gives the nth term of the geometric sequence (). To find the common ratio, we can take any term and divide it by its preceding term (rearrange the formula to get ). If we take 24 and divide it by 16, we get the common ratio of 3/2 (, ).

Answer:

Avoid Using too many statistics

Step-by-step explanation:

when a speaker is giving a speech, the listeners prefer main points to hearing too much of statistics. Too many statistics bore the audience and sometimes divert their attentions from the crux of the speech. If statistics are to be given, they must be clearly expressed and the source should be clearly stated.

Numbers that are of large decimal points can be rounded off so as not to confuse the audience and to make them grasp the main idea.
