Answer:
Option B - 11.6 m below the surface of water.
Step-by-step explanation:
Given : Ben and Cam are scuba diving. Ben is 15.815.8=15.8 meters below the surface of the water. Cam is 4.24.2= 4.2 meters above Ben.
To find : What is Cam's position relative to the surface of the water?
Solution :
Ben is 15.8 meters below the surface of the water.
Cam is 4.2 meters above Ben.
So, Cam is below the surface of water by meter.
Therefore, Option B is correct that Cam is 11.6 meters below the surface of the water.

For all of these problems, make equation into slope-intercept form to be able to see what the slope is.
answer to 1.d. is neither
Answer:
A
Step-by-step explanation:
Recall that for a quadratic equation of the form:
The number of solutions it has can be determined using its discriminant:
Where:
- If the discriminant is positive, we have two real solutions.
- If the discriminant is negative, we have no real solutions.
- And if the discriminant is zero, we have exactly one solution.
We have the equation:
Thus, <em>a</em> = 2, <em>b</em> = 5, and <em>c</em> = -<em>k</em>.
In order for the equation to have exactly one distinct solution, the discriminant must equal zero. Hence:
Substitute:
Solve for <em>k</em>. Simplify:
Solve:
Thus, our answer is indeed A.
