Uhhhhhhhhhhhhhhhhhhhhhhhhhhh
The formula to find the mid-point of a line segment give the two end points is:
M
=
(
x
1
+
x
2
2
,
y
1
+
y
2
2
)
Where
M
is the midpoint and the given points are:
(
x
1
y
1
)
and
(
x
2
y
2
)
Substituting the values from the points in the problem gives:
M
=
(
−
3
+
1

,

+

)
M
=
(
−

,

)
M
=
(
−

,
0
)

∫ x · e ^(-x² ) dx = / The substitution: u = - x², x d x = - du / 2

+∞
= - 1/2 · ∫ e ^(u) du = - 1/2 · e ^(-x²) /
- ∞
e^(-∞) = 1 / e^(∞)
= -1/2 · [ 1/ e^(∞) - 1/ e^(∞) ] = -1/2 · ( 0 - 0 ) = 0
(7/8)/(1/6)= 5.25
you cant make .25 of a recipe, so she can make it 5 times
