Yes, very nice happy :)

Well square units anyway - I didn't see any mention of feet. :)

x^2+2x+1=0 x=-1 ?

because

(-1)^2=1

2*-1=-2

and

1-2+1=0

All answers must be converted to imperial minums.  Seriously!

Find correct angle

2 3/4=11/4

1 1/2=3/2

2 3/4+1 1/2=11/4+3/2=11/4+6/4=17/4

then use ur toes

.

f(9)=9-8=1

Notice the pattern, Melody

64^15 mod 391  = 4

64^59mod 391 = 4

64^103mod 391 = 4

Which leads us to believe that this pattern repeats every 44th power

Therefore

64^(15 + 44n)mod 391 = 4 for all positive integers, n

So

64^(15 + 44*5)mod 391  = 64^(15 + 220)mod 391 = 64^(235)mod 391  = 4 ....!!!

if you type it like it is then it will give you an anser on the home calc 0.01166180758

In this quadrant, if tangent Θ = -2, then y = 2 and x = -1 and r =√5

Then, cos2Θ = cos^2Θ - sin^2Θ

And we have

cosΘ = -1/√5      sinΘ = 2/√5     ....  so ....

cos^2Θ - sin^2Θ =

1/5 - 4/5   =   -3/5   = -.6

Let x be the number Louis has

The, since Jake and Zack have the same number, we have

2x = 5x - 60       subtract 2x from both sides, add 60 to both sides

60 = 3x             divide by 3 on both sides

20 = x  =  the number that Louis has....

Can you work it out from the graph

Thanks, Mel.....!!!

Very impressive Chris :)

There is a toggle on the bottom of the web2 calc for this.

Translation means slide - so reflection or rotations are not correct

Verical means straight up or down (higher of lower)

-9 means lower by nine

By definition, a rectangle has two sides which equal each other and a top & bottom which equal each other:  A dollar bill is a good example.

The perimeter is the distance around the rectangle:  Side + Side + Top + Bottom.  Your problem states that one of the sides is 3 times longer than the other, so you know that the Top and Bottom each equal 3xSides.

By substitution, the perimeter now = Side + Side + 3 Sides + 3 Sides, which equals 8 sides in length (1+1+3+3=8).  You're told that the perimeter is 70 (units?), so each side is 70/8 units, which is 8.75 (units).  The top and bottom are each 3sides long, which equals 3*8.75 = 26.25 (units):

Double check by adding the 4 lengths together:  8.75 + 8.75 + 26.25 + 26.25 = 70.  Yep, it works.

I just entered this into the calc

mod(64^235,391)

$$\left({{\mathtt{64}}}^{{\mathtt{235}}}\right) {mod} \left({\mathtt{391}}\right) = {\mathtt{4}}$$

I don't know how to do this without the calc  

450+10=460
460/10 = 46

C'mon, flex your brain a little.

Using dimensional analysis, we have

158,000 ft x .3048m/1 ft x 1km/1000m = 48.1584 km

Just as NotTheBestMathMaster found ....!!!!

go to post a new question - where you just were

Look at info for new people.

That and other questions are answered there.

Bio, this is a snark question.

It is best to be ignored.

Happy's answer is ok
