A matrix is diagonal if
In other words, you want non-zero elements only when the indices of the row and the column are the same: the first element of the first row must be non zero, the second element of the second row must be non-zero, and so on. All other elements must be zero.
Answer:
Number of students(n1)= 4,402
Step-by-step explanation:
Giving the following information:
Number of students= 4,512
Declining rate= 2.5%
<u>To calculate the number of students next year, we need to use the following formula:</u>
Number of students (n+x)= number of students (n0) / [(1+declining rate)^(n+x)
x= number of years
Number of students(n1)= 4,512/1.025
Number of students(n1)= 4,402
Answer:
∠c = 33°
∠b= 147°
Step-by-step explanation:
A line is 180°, and ∠c + 147° make up a linear pair.
180 - 147 = 33°
∠c is 33°.
∠b and 147° angle are vertical angles, meaning that they have the same angle measure.
∠b = 147°.
