The (i,j) minor of a matrix A is the matrix Aij obtained by deleting row i and column j from A it is true.
The (i,j) minor of a matrix A is the matrix Aij obtained by deleting row i and column j from A. A determinant of an n×n matrix can be defined as a sum of multiples of determinants of (n−1)×(n−1) sub matrices.
This is done by deleting the row and column which the elements belong and then finding the determinant by considering the remaining elements. Then find the co factor of the elements. It is done by multiplying the minor of the element with -1i+j. If Mij is the minor, then co factor, 
+ 
.
Each element in a square matrix has its own minor. The minor is the value of the determinant of the matrix that results from crossing out the row and column of the element .

Answer:
Step-by-step explanation:
a/7+b
You simply have to use the values provided in the equation given. If a=49 and b=7 you have
49/7+7, since 49/7=7 you have
7+7 which equals
14
Answer:
The populaton in year 1991 will be of 5178.9 million of people
and the population in year 2020 will be of 8524.60 million of people
Step-by-step explanation:
We measure the time t in years and let t=0 in the year 1950.
We measure the population P(t) in millions of people, then P(0)=2560 and P(10) = 3040.
Since we are assuming that dp/dt=kP, this theorem gives the following.
The relative growth rate is about 1.7% per year and the model is
<em>Year 1991 is equal in our formula to 41 and year 2020 is equal to 70. </em>Replacing,
Therefore the populaton in year 1991 will be of 5178.9 million of people and the population in year 2020 will be of 8524.60 million of people
Answer:
In order to do so, we need to use basic algebra. The angles in a kite add up to 360 degrees. so we form the following equation.
x + y + y + 16 = 360
x + y + y = 344 <----(360 -16)
Each letter or variable represents an angle measure. the measures of the three angles left. The 16 degrees is on the bottom of the kite and the angle opposite is the top angle. the two side angles will be the same measure that's why they are both y.
x + 2y = 344
The two side angles will be 90 or greater because there is only 1 acute angle. 90 is the smallest number that can be chosen. so we do the following.
Step-by-step explanation:
x + 2(90) = 344
x + 180 = 344
x = 344-180
x = 164
THE MAXIMUM WHOLE NUMBER MEASURE OF THE ANGLE OPPOSITE OF THE 16 DEGREE ACUTE ANGLE IS 164 DEGREES*
The ratio between Area of D and Area of C is 28:7.
That means the simplified version is 1:4.
From our ratio, we can derive that the scale factor is 4.
