This makes sense but the second one is kinda hard to process lol

LOL!!!!

EP  only paid a SMALL amount for this endorsement!!!

{ Seriously....he's one of our best "Answerers"  }

Yay! Thank you

Rate of change =

______________   =         ________   =      ______  =   ____ =    ____

   64 -   8                                 56                    56               56           28

Correct, Jenny!!!!

Hang in there....this was difficult for me , too !!!!

These are somewhat tricky !!!

First one

Angle DFE   intercepts a diameter......when this is the case....its measure = 90°

So   angle  FDE =  180 - 90 - 63 =   27°

And the arc it intercepts - FE -  is twice its measure =  54°

Second one.....even tougher!!!

Angle GHJ  intercepts arc GJ   =  360 - arc IJ - arc HI - arc GH

So arc GJ =   360 - 135 - 31 - 86 = 108°

And angle GHJ intercepts this arc so it measures (1/2)(108)  = 54° 

Notice that angle GIJ intercepts the same arc....so....it also measures 54°    !!!!!

Oh wow I was way off >.< i'm so bad at this

First one....we need to calculate minor arc WY.....

This is  360 - (86 + 156)  =  118°

Angle WXY intercepts this arc ...so...it measures (1/2)(118)  =  59°

Second one

You have calculated arc RT  correctly !!!!

But we need arc RS

This =   360 - arc RS - arc TS  =    

360 - 84 - 171  =

105°

OK, good   !!!!

(14/14*14) +14  -  (14/15/15*15) +15-15  =

(1)*14 + 14  - ( 14* 15 / 225) +  0

14 + 14  -  (14 /15)  =

28 - 14/15 =

[ 420 - 14] / 15 =

406 / 15

10^9*(16*3) =

10^9 * (48) =

48,000,000,000

Thanx for all of the kind words , Folks.....           People are gonna think I put ya up to it!   

Oh those were easier than I thought lol

We are using the theorem that an inscribed angle =  1/2  the measure of its intercepted arc

1.  Angle  JKL =  88°

So the arc it intercepts - JML -  is twice this  =  176°

2.  Angle ABC intercepts an arc of 34°....so...its measure is 1/2 of this =  17°

would it be -5?

If  f(-x)   = (x)....then the function is even...so...

(-x)^6 - (-x)^4 =

x^6 - x^4

And this is = f(x)...so....it is EVEN

We "read" a function from left to right

The intervals of increase  are where the function rises from left to right  ⇒  (−∞, 0)   and (1,2)

A function is constant on the interval where  it is parallel to the x axis....in other words....where it forms a horizontal line

This is from (-4, 0)

The relative minimum is the lowest y value attained by the function....

What is this  ???

Wow!!!!....impressive, Heureka!!!

Very nice, Alan!!!!

I have questions questions to answer and I am Trying to beat Hiylink in hearts XD!!
