Its one of the two first ones, I can’t really figure it out but that’s a hint
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
=
=
= 81π / 20
volume of the solid is 3.180
Answer:
DF is your answer. Hope this helps!
Step-by-step explanation:
There are 6 numbers on a dice 1,2,3,4,5,6. If you want to get a 4 or a 5, that would be 2 numbers out of the total number of numbers There 6 numbers in total so the probability of getting a 4 or 5 is 2 out of 6 or 1 out of 3 or 1/3
Y=-3x+ 2
hopefully this is right!
