The 100 is 100 or 25×4 is hundred??
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
C. (2.4) because that point is the only one that is in both the blue and red shaded areas.
Answer:
b. 6

Answer:
Step-by-step explanation:
hello :
y+2=x²−2siny
calculate y' : y' = 2x -2y'cosy
when x= 2 and y=0 ( at the point(2,0)
) y' is the slope :
y' = 2(2)-2y'cos0 but cos0 =1
y' = 4 -2y'
3y' =4
so : y' = 4/3
