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:
Since we have a 30° - 60° - 90° triangle, we can calculate any side by knowing at least one out of three:
Since the length of the hypotenuse is twice as long as the shorter leg, we have:
The length of the short leg is: 25/2 = 12.5
Since the length of the longer leg is equal to the length of the shorter leg
multiply by square root of 3 we have:
The length of the longer leg is: 12.5 × √3 ≈21.65
=> The perimeter of the triangle is: 25 + 12.5 + 21.65 = 59.15
Answer:
3x + 14 items
Step-by-step explanation:
First plant produces 5x + 11 items
Second plant produces 2x - 3 items
First plant production - second plant production = 5x + 11 - (2x - 3)
5x + 11 - 2x + 3 = 3x + 14 items
7/2 can be = to 3 and 1/2
1 day is = to 24 hours
3 1/2 times 24 = 84 hours
The answer is c because there asking for the rate of change which is $20 per month
