Hello ! :D

To divide fractions, multiply by the multiplicative inverse:

(29/8) / (1/4)  =  (29/8) x (4/1)  =  116/8  =  29/2  =  14.5

Say hello, to friends yea know, and everyone you meet. :)

Supplementary angles are two angles whose sum is 180^o.

If one angle is  x^o,  the other angle will be  (180 - x)^o.

One angle is three times the measure of the other (supplementary) angle:  x  =  3(180 - x)

Solve:                                                                                                             x  =  540 - 3x

                                                                                                                     4x  =  540

                                                                                                                       x  =  135

This makes the other angle:  180 - x=  180 - 135  = 45.

The two angles measure  45^o  abd  135^o.

If the children are Alan (=0.5) and Barb (=0.3):

  this means:  not Alan = 0.5  and  not Barb  = 0.7:

a) both Alan and Barb:  0.5 and 0.3  =  0.5 x 0.3  =  0.15

b) exactly one:  either Alan and not Barb  or  not Alan and Barb

                                =  0.5 x 0.7  +  0.5 x 0.3  =  0.35 + 0.15  =  0.50

c) neither one:  not Alan  and  not Barb  =  0.5 x 0.7  =  0.35

d) at least one:  both Alan and Barb  or  Alan and not Barb  or  not Alan and Barb

                         =  0.5 x 0.3  +  0.5 x 0.7  +  0.5 x 0.3  =  0.15  +  0.35  +  0.15  =  0.65

With "and", you multiply; with "or", you add.

Merry Christmas to you too!!!!

Are you drunk or high or just crazily happy? Is it all those combined?😧

Find the derivative of the following via implicit differentiation:
d/dx(y) = d/dx(-(x sqrt(36-x^2))+36 sin^(-1)(x/6))
The derivative of y is y'(x):
y'(x) = d/dx(-(x sqrt(36-x^2))+36 sin^(-1)(x/6))
Differentiate the sum term by term and factor out constants:
y'(x) = 36 d/dx(sin^(-1)(x/6))-d/dx(x sqrt(36-x^2))
Use the product rule, d/dx(u v) = v ( du)/( dx)+u ( dv)/( dx), where u = x and v = sqrt(36-x^2):
y'(x) = 36 (d/dx(sin^(-1)(x/6)))-sqrt(36-x^2) d/dx(x)+x d/dx(sqrt(36-x^2))
Simplify the expression:
y'(x) = -(sqrt(36-x^2) (d/dx(x)))-x (d/dx(sqrt(36-x^2)))+36 (d/dx(sin^(-1)(x/6)))
The derivative of x is 1:
y'(x) = -(x (d/dx(sqrt(36-x^2))))+36 (d/dx(sin^(-1)(x/6)))-1 sqrt(36-x^2)
Using the chain rule, d/dx(sqrt(36-x^2)) = ( dsqrt(u))/( du) ( du)/( dx), where u = 36-x^2 and ( d)/( du)(sqrt(u)) = 1/(2 sqrt(u)):
y'(x) = -sqrt(36-x^2)+36 (d/dx(sin^(-1)(x/6)))-(d/dx(36-x^2))/(2 sqrt(36-x^2)) x
Differentiate the sum term by term and factor out constants:
y'(x) = -sqrt(36-x^2)+36 (d/dx(sin^(-1)(x/6)))-(d/dx(36)-d/dx(x^2) x)/(2 sqrt(36-x^2))
The derivative of 36 is zero:
y'(x) = -sqrt(36-x^2)+36 (d/dx(sin^(-1)(x/6)))-(x (-(d/dx(x^2))+0))/(2 sqrt(36-x^2))
Simplify the expression:
y'(x) = -sqrt(36-x^2)+(x (d/dx(x^2)))/(2 sqrt(36-x^2))+36 (d/dx(sin^(-1)(x/6)))
Use the power rule, d/dx(x^n) = n x^(n-1), where n = 2: d/dx(x^2) = 2 x:
y'(x) = -sqrt(36-x^2)+36 (d/dx(sin^(-1)(x/6)))+(2 x x)/(2 sqrt(36-x^2))
Simplify the expression:
y'(x) = x^2/sqrt(36-x^2)-sqrt(36-x^2)+36 (d/dx(sin^(-1)(x/6)))
Using the chain rule, d/dx(sin^(-1)(x/6)) = ( dsin^(-1)(u))/( du) ( du)/( dx), where u = x/6 and ( d)/( du)(sin^(-1)(u)) = 1/sqrt(1-u^2):
y'(x) = x^2/sqrt(36-x^2)-sqrt(36-x^2)+36 (d/dx(x/6))/(sqrt(1-x^2/36))
Factor out constants:
y'(x) = x^2/sqrt(36-x^2)-sqrt(36-x^2)+(36 (d/dx(x))/6)/sqrt(1-x^2/36)
Simplify the expression:
y'(x) = x^2/sqrt(36-x^2)-sqrt(36-x^2)+(6 (d/dx(x)))/sqrt(1-x^2/36)
The derivative of x is 1:
y'(x) = x^2/sqrt(36-x^2)-sqrt(36-x^2)+(1 6)/sqrt(1-x^2/36)
Simplify the expression:
y'(x) = x^2/sqrt(36-x^2)-sqrt(36-x^2)+6/sqrt(1-x^2/36)
Expand the left hand side:
Answer: | y'(x) = x^2/sqrt(36-x^2) - sqrt(36-x^2) + 6/sqrt(1-x^2/36)

Just substitute those numbers for x, one at a time, on the right-hand side and use calculator to get the answers you want.

whats half of half,

1/2 X 1/2=1/4

Solve the following system:
{19 y-14 x = 46 |     (equation 1)
14 x-9 y = 102 |     (equation 2)
Add equation 1 to equation 2:
{-(14 x)+19 y = 46 |     (equation 1)
0 x+10 y = 148 |     (equation 2)
Divide equation 2 by 2:
{-(14 x)+19 y = 46 |     (equation 1)
0 x+5 y = 74 |     (equation 2)
Divide equation 2 by 5:
{-(14 x)+19 y = 46 |     (equation 1)
0 x+y = 74/5 |     (equation 2)
Subtract 19 × (equation 2) from equation 1:
{-(14 x)+0 y = (-1176)/5 |     (equation 1)
0 x+y = 74/5 |     (equation 2)
Divide equation 1 by -14:
{x+0 y = 84/5 |     (equation 1)
0 x+y = 74/5 |     (equation 2)
Collect results:
Answer: | x = 84/5          and              y = 74/5
 

how'd you get that?

Go play and have fun! You can't " break" it, even if you wanted to!.

It is -5.6 =Y and 3.7 =X I rounded to the nearest tenth.

Do you think that EVERYBODY knows what "GST" and "PST" mean? I assume that they "sales taxes", and if so, what are the rates? You have to state them like 5%, or 10%.........etc. Remember that the person who will answer your question might be from Germany, or Australia, or Russia.......etc. Got it?

NOPE, I broke the site!☹️

I don't know :(

I'm sorrrrry :)

Aww, thanks for coming on to a website like this where people are uber stressed obviously cuz of intolerable math problems and asking something sweet like that. So thoughtful 🙂 My day is ok . . . But omg what is ! in math? Idk how an exclamation mark can be math . . .

I'm finally done with my Finals! For today.. Then there comes Monday & Tuesday...

If yall have any questions.. please tell me :)

:) hehe

WOW Hayley! You answer that question in less than 3 minutes!

You get the right answer too. hahaha
