For matrix subtraction, you subtract the corresponding cell of the second matrix from the first. So, looking at the first spot, you have 4 (from the first matrix) - 4 (from the second matrix) = 0 (the first number in the output matrix). Continuing that for the next spot, -4 - -3 = -4 + 3 = -1. Finally, -2 - 5 = -7. This means your answer is [0 -1 -7].
Answer:
For covering
unit area of the entire playground, the amount of sand required is equal to volume of
buckets of sand.
Step-by-step explanation:
Given -
volume of sand in bucket is able to cover
area of the entire playground
Thus,
For covering
unit area of the entire playground, the amount of sand required is equal to
of the total volume of sand in bucket
For covering
unit area of the entire playground, the amount of sand required is equal to

For covering
unit area of the entire playground, the amount of sand required is equal to volume of
buckets of sand.
Given:
m is directly proportional to the cube of h.
m = 525 when h= 5.
To find:
The equation connecting m and h.
Solution:
m is directly proportional to the cube of h.

...(i)
Where, k is the constant of proportionality.
Putting m = 525 and h= 5, we get



Putting k=105 in (i), we get

Therefore, the required equation is
.
