The maximum rate, r, that the scuba diver may descend is r≤ 11.2
Given the following parameters:
- Initial length = 14.7feet
If the scuba diver reaches a depth no more than 65.1 feet below sea level, then;
r ≤ (65.1 - 14.7)/4.5
r≤ 50.4/4.5
r≤ 11.2
Hence the maximum rate, r, that the scuba diver may descend is r≤ 11.2

The coefficients of any row of Pascal’s triangle can be calculated using (A) combinations
<h3>How to determine the coefficients?</h3>
A binomial expansion is represented as:
Where:
x >= 0 and x <= n
In the above expression, the coefficient is:
The above represents the xth term of a Pascal triangle and it is a combination expression
Hence, the coefficients of any row of Pascal’s triangle can be calculated using (A) combinations

The answer is <span>2(–4y + 13) – 3y = –29
Step 1: Express </span><span>x from the second equation
Step 2: Substitute x into the first equation:
The system of equations is:
</span><span>2x – 3y = –29
x + 4y = 13
Step 1:
</span>The second equation is: x + 4y = 13
Rearrange it to get x: x = - 4y + 13
Step 2:
The first equation is: 2x – 3y = –29
The second equation is: x = - 4y + 13
Substitute x from the second equation into the first one:
2(-4y + 13) - 3y = -29
Therefore, the second choice is correct.
By the chain rule,
When
, we get
, so at this point the partial derivative of
with respect to
takes on a value of
False, all rational functions have to contain a rational expression, or nothing would even be solvable.
Hopefully this helps!
