Pardon?? i don't understand sorry

Just put in  ' 0 ' for C   and calculate F

  then put in   5   for C   and calculate

    etc.....

Wow, quite the echo here on the forum !

a) 0°C=_______ °F
b) 5°C=_______ °F
c) 15°C=______ °F
d) 37°C=______ °F

You didn't post anything to be converted

F^o =  9/5 C^o  + 32

oops that was a mistake sorry its 0.8^3

yea its 0.8s^3

Put in 2 for s

.8 (2)^2 = 3.2 gm      (Are you sure that isn't  . 8 s³ ?)

Thank you so much!

x + y = 6.......................(1)  

x^3 + y^3 =60.............(2)

y =6 - x

Solve for x:
(6 - x)^3 + x^3 = 60

Expand out terms of the left hand side:
18 x^2 - 108 x + 216 = 60

Divide both sides by 18:
x^2 - 6 x + 12 = 10/3

Subtract 12 from both sides:
x^2 - 6 x = -26/3

Add 9 to both sides:
x^2 - 6 x + 9 = 1/3

Write the left hand side as a square:
(x - 3)^2 = 1/3

Take the square root of both sides:
x - 3 = 1/sqrt(3) or x - 3 = -1/sqrt(3)

Add 3 to both sides:
x = 3 + 1/sqrt(3) or x - 3 = -1/sqrt(3)

Add 3 to both sides

x = 3 + 1/sqrt(3)  and y = 3 - 1/sqrt(3)  OR   y = 3 + 1/sqrt(3)  and x = 3 - 1/sqrt(3) 

If b elimonates some of the terms when adding like terms, it can diminish the degree of the result

   if b = - 1/2         the x^4 and the x^2 terms will cancel   and you will have a degree of ONE result

Multiplying by a constant will not change the degree of g(x)

   adding them will only result in a degree of 4 at the greatest

First find value of x

8x-4 = 5x+11

x = 5

Then find height of isoc triangle

36^2 - 9^2 -= h^2   h = 34.856

area  then = 1/2 base X height

                     1/2  18 x 34.856 = ........ units ²

Less than or equal to the solid line    y<= - 2x +2

less than dashed line                         y < 1/3 x + 2

Less than or equal to the solid line    y<= - 2x +2

less than dashed line                         y < 1/3 x + 2

To prove that the shaded area is equal to the area of a triangle (ABC), we have to find the area of the entire figure, and then subtract the area of the largest semicircle.

Let the sides of a triangle ABC be 3-4-5

Let denote the areas of 3 semicircles, starting with the smallest one:    A1, A2, and  A3

A1 = (1.52*pi) /2 = 3.534291735 u2

A2 = 2pi = 6.283185307 u2 

A3 = (2.52*pi) /2 = 9.817477043 u2

ΔA = (3*4) /2 = 6 u2

ΔA = ( A1 + A2 + ΔA ) - A3

6 = 6  

Find real numbers x and y such that x + y = 6 and x^3 + y^3 = 60.

Hello Guest!

\(x+y=6\\ y=6-x\\ x^3+y^3=60\\ x^3+(6-x)^3=60\\ x^3+(36-12x+x^2)(6-x)=60\)

\(x^3+216-36x-72x+12x^2+6x^2-x^3=60\\ 18x^2-108x+216=60\)

\(18x^2-108x+156=0\)

\(x = {-108 \pm \sqrt{11664-4\cdot 18\cdot 156} \over 2\cdot 18}\\ x=\frac{-108\pm 20.785}{36}\)

\(x_1=-2.423\\ x_2=-3.577\)      \(y_1=8.423\\ y_2=9.577\)

13y -1 = 90

2x-7 = 39

6z-4 = 180 - 90 - 28               Look at these , understand where they came from...then solve...

expand  3x+2y)^4

Draw a Venn diagram..... you will find  9 students play both sports

9/29

[9 + (90 *2) + (900* 3) + 4] =9 + 180 + 2700 + 4 =2,893 digits - which includes 1000.

There are 111 multiples of 9 between 1 and 1000.
