The sum of three consecutive numbers is 12 find the numbers
snow_tiger [21]
Let x,y,z be those numbers.
x+y+z = 12
Since x,y,z are consecutive: y=x+1, and z = x+2
Let's replace y and z by their new values:
x+x+1+x+2=12
3x+3=12
You subtract 3 from each side to get variables on a side, and numbers on the other:
3x=9
You divide both sides by 3:
x=3

y=x+1 = 3+1 = 4
z=x+2 = 3+2 = 5

So the numbers are 3; 4 and 5.

You can re-check your answers (very important):
3+4+5 = 12
3;4;5 are consecutive numbers.
The answer has been approved.

Hope this Helps! :)

The base of a solid in the region bounded by the parabola x2 + y = 4 and the line x + y = 2. Cross sections of the solid perpend
Evgen [1.6K]

Answer:

volume of the solid is 3.180

Step-by-step explanation:

given data

line x + y = 2

parabola  x2 + y = 4

to find out

the volume of the solid

solution

we draw a graph between line and parabola as show in fig given below attach

line cut at (-1,3) and (2,0)

so the length of diameter is ( 4 - x²) - (2 - x)

and radius of this semi circle will be ( 4 - x² - 2 + x ) /2

radius = (-x² + x + 2 ) /2

and r(x) will be  =  (-x² + x + 2 ) /2

and A(x) will be  = π ( r(x)² ) /2

we will integrate from -1 to 2

= \int_{-1}^{2}A(x))

= \int_{-1}^{2}(π ( (-x² + x + 2 ) /2)² ) /2))

= 81π / 20

volume of the solid is 3.180
