Answer:
Verified
Step-by-step explanation:
Let the diagonal matrix D with size 2x2 be in the form of
![\left[\begin{array}{cc}a&0\\0&d\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Da%260%5C%5C0%26d%5Cend%7Barray%7D%5Cright%5D)
Then the determinant of matrix D would be
det(D) = a*d - 0*0 = ad
This is the product of the matrix's diagonal numbers
So the theorem is true for 2x2 matrices
Answer:
1600
Step-by-step explanation:
1200 = 75%
1200 ÷ 3 = 25% = 400
400 x 4 = 1600
Answer:
363 ft
Step-by-step explanation:
We can use a ratio to solve
330ft x ft
------------ = ---------------
10 seconds 11 seconds
Using cross products
330*11 = 10x
Divide by 10
330*11/10 = x
363 = x
Answer:
B
Step-by-step explanation:
the incenter is found by constructing angle bisectors and then intersecting the three angle bisectors.
We apply the following property:
(x^n)^m = x^(n • m)
Let m = 2
(P^1/2)^2 = P^(1/2 • 2) = P
