I didn't understand the following matrix manipulation, as shown in the attached photo. How was it done?
1 answer:
The picture I included shows how to to a 2x2 and 2x1 matrix multiplication if that’s what you’re confused about.
If you’re wondering what you can learn from the example. The product matrices on the left are the same except the terms in top matrix each have an added term. So the difference between the two sets of matrices result in the top having two extra terms after the multiplication.
Let me know if you still need more.

Answer: hello the complete question is attached below
answer:
A) Group symbol = SW
B) Group name = well graded sand , fine to coarse sand
C) It is not a clean sand given that ≤ 50% particles are retained on No 200
Explanation:
<u>A) Classifying the soil according to USCS system</u>
( using 2nd image attached below )
<em>description of sand</em> :
The soil is a coarse sand since ≤ 50% particles are retained on No 200 sieve, also
The soil is a sand given that more than 50% particles passed from No 4 sieve
The soil can be a clean sand given that fines ≤ 12%
The soil can be said to be a well graded sand because the percentage of particles passing through decreases gradually over time
Group symbol as per the 2nd image attached below = SW
B) Group name = well graded sand , fine to coarse sand
C) It is not a clean sand given that ≤ 50% particles are retained on No 200
