Answer:
D
Step-by-step explanation:
x^2 - 4x + 4 = 36
Take the square root on both sides.
x - 2x + 2 = 6
Answer:
4.4
years corresponding to 4 years and 5 months (more or less)
Step-by-step explanation:
Let us set
P
=
25
we get:
25
=
8
e
0.26
t
rearrange:
e
0.26
t
=
25
8
take the natural log of both sides:
ln
[
e
0.26
t
]
=
ln
[
25
8
]
simplify:
0.26
t
=
ln
[
25
8
]
t
=

Answer:
146.41
Step-by-step explanation:
third order determinant = determinant of 3×3 matrix A
given ∣A∣=11
det (cofactor matrix of A) =set (transpare of cofactor amtrix of A) (transpare does not change the det)
=det(adjacent of A)
{det (cofactor matrix of A)} ^2 = {det (adjacent of A)}
^2
(Using for an n×n det (cofactor matrix of A)=det (A)^n−1
)
we get
det (cofactor matrix of A)^2 = {det(A) ^3−1
}^2
=(11)^2×2 = 11^4
=146.41
