1/3 as a decimal fraction has an infinite number of recurring 3's.   1/3 = 0.33333..... the 3's go on forever!

.

Just multiply 1840 by 1.2

Or calculate 0.2*1840 then add the result to 1840.

20% means 20/100 which is 0.2

.

It's true as long as x is greater than zero.

Yes, it is good to enjoy books rosala :)

Looks like I'm the only " senior" here! 9th grade! Anyone anyone of my type anyone????

You may find this well worth watching :)

okay part a

a) sec(3pi/4)        reference angle: pi/4  and Value is -2/sqroot2

I have drawn a unit circle.  It is an excellent idea for you to completely understand the unit circle and its significance.  It makes much of trigonometry much easier. :)

A unit circle is a circle centre (0,0) and radius 1 unit.

I have drawn the 3pi/4 angle where it belongs.  If you drop a perpendicular from the ray down onto the x axis you will form the reference angle at at the origin. So the reference angle is  pi/4

NOW  sec is  1/cos 

$$\\cos (\pi/4) = cos 45^0 = \frac{1}{\sqrt2}=\frac{\sqrt2}{2}=\frac{\frac{\sqrt2}{2}}{1}=\frac{adj}{hyp}\\\\
$the hypotenuse is 1 because it is the radius of the unit circle$\\
$so the x value must be $\frac{\sqrt2}{2}$ but it is negative, you can see that the x is negative there!\\
now \\
sec\left\frac{\pi}{4}\right=\frac{hyp}{adj}=\frac{1}{x\;co-ordinate}=\frac{1}{-\frac{\sqrt2}{2}}=\frac{-2}{\sqrt2}$$

That right melody.... Even I noticed some limit- crossed posts and I think such personal things should be avoided!

i jut read this post of ties excluding the comments! I haven't been getting any time now a days! Becoz I'm trying to develop a reading habit and not just stick to the internet be coz my last trip showed how close I was to the Internet! 

Currently in in reading a very very very fat book that's the book thief! It's the best I've read till now! I'm at is end and I just have to keep it away from me coz when I see it I go onto ready and can't prepare for the tests so yeah it's awesome! I can say the book is way better than the movie awe the writer gives you such a 3d feel ! I almost wanted to cry and laugh out loud!

Times means multiply so 900 

x 3 is 2700 horses! I'll have 2700 horses!

woah that's so much i don't even know how to tame a horse or ride it! Haha

It would be interesting to know exactly what the examiners had in mind. A lot hinges on what is meant by "using the numbers".

if we can use mod, here is one of infinite possibilities:

1357911 mod 13 + 111315 mod 13 + 13571 mod 13 = 30

    😡   😡   😡   😡   😡

20% of what? The same money?

ohhhhhhhhhhhh i get it know

ITS 312.5 NUMbER THINGYS!!!!

once again, my friend, you've done well

good job, Heather

k, 5 to the 4th power, this means:

5*5*5*5

5*5=25*5=125*5=625

overall, 5^2 is equal to 625.

HOWEVER, then we have ^1/2

so, 625^1/2, and that equals:

312.5

overall, the correct answer is:

312.5

or as Titanium Rome would say, just for God's sake, 312.5 number thingys

900*3=2700

you would get overall 2,700 horses

thinking about this ..... 

93.3333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333 etc.

The "child" function is given by :

y = (8)cos3(x - pi/3)

See both here: 

Note......

(x - 5) / [ x^2 - 6x + 5] =

(x - 5) / [ (x - 1) (x -5) ] =

1 / (x - 1)

There will be a "hole" at x = 5......but the discontinuity at x = 1  isn't "removable".....there's a vertical asymptote at that point......

Here's the graph.......
