ANSWER
EXPLANATION
The dimensions of a matrix is of the form:
The dimensions of the first matrix is
The dimensions of the second matrix is
Since the inner products are the same,the outer products give the dimensions of the product of the two matrices.
Therefore the dimensions of the product is a 2×2 matrix.
Answer:
There will be 22.5 grams left after 32 hours.
Step-by-step explanation:
A half-life is how long it takes for half of the amount to go away. In this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.
32hrs/8hrs = 4 half lives.
Now we can raise 1/2 to the power of how many half lives we have (2). Then we multiply that by the amount in the sample.
(1/2)^4 * 360
1/16 * 360
22.5 grams
And this is an exponential function.
