For that you will need  f( c(x) )    the c(x) will convert the degrees kelvin to celcius, then the f (  ) will convert the resultant celcius degrees to farenheit

f ( c (x) )  =   f ( x-273.15)     =   9/5 (x-273.15) + 32      Where 'x' is Kelvin degrees and the result is Farenheit degrees

Time to get offline and go outside for some fresh air?

The question does not state it has gone up 350%  ...the wording says it is 350% of what it was...

That is why I answered the question the way I did.

"...A report says that a theater ticket is now 50% of what it was 20 years ago....'      the answer would be $50.

If it said it was 50% MORE than it was 20 years ago it would be $ 150

Tangent of angle relative to horizontal is given by

TAN =  opposite / adjacent  = 1490 /(- 300) =  -78.616  degrees from 180 degrees  or  101.4 degrees from the 'zero' angle portion of the horizontal....(when rounded to the nearest 0.1 degree)

$100 x (3.5) = $ 350.00

If it is 350% MORE than it was 20 years ago (the question does not ask this)  then  it is  100 + 100 (3.5) = 450.00

SO    a^2 + b^2  +  c^2  = 200   (given in the question)

we know from Pythag theorem that   ( a^2 + b^2 )  = c^2    Substitute this into the first equation results in:

c^2 + c^2  = 200

c^2 = 100

c = hypotenuse = 10  

16/64  simplified  =   4/16  =  2/8  = 1/4   =   0. 25

Substitute the values you are given to find the other value of the ordered pair to be graphed:

you have  one point   x=(  , 0)     if you substitute '0' for y in the equation you will get   2x=-4   or  x= -2

so the first orderd pair to be graphed is   (-2,0)

Do the same theing for the other given  y=(0, )   to get    2y= -4    y= -2       so the second orderd pair

 to be graphed is  (0,-2)......

Graph these two points and draw the line through them......

I'll assume you meant  \(\sqrt[3]{39}\)     Which is the 'cube root' of 39

what number times itself three times equals 39      x * x * x = 39          x = 3.3912

Divide both sides of the equation by '4' to get

x^2 = 25

SQRT both sides

x=5
