Answer:
20.3
Step-by-step explanation:
Based on the total of intervals vs the number of intervals Amy attended her CA percentage is 75%
<h3>What is the CA percentage?</h3>
The CA percentage measures the commitment of an employee to be logged in during the intervals that were assigned to him/her to work.
In this way, the CA percentage is equal to 100% if the employee worked as scheduled. Moreover, this percentage can be affected by factors such as:
- Technical issues.
- Human errors.
In the case of Amy, there is a total of 12 intervals and it is known:
- She had a technical issue that prevented her from working, but this was reported so it is unlikely this is considered in her CA.
- She missed three intervals because she looked at her schedule wrong.
Based on this information, let's calculate her CA:
- 12 intervals = 100%
- 9 intervals = x
- x = 9 x 100 / 12
- x = 900 / 12
- x = 75%

Answer:
While both types of interest will grow your money over time, there is a big difference between the two. Specifically, simple interest is only paid on principal, while compound interest is paid on the principal plus all of the interest that has previously been earned.
Answer:
(1, -3)
Step-by-step explanation:
You can see where the two lines intersect - that's the solution.
To find the gradient of the tangent, we must first differentiate the function.
The gradient at x = 0 is given by evaluating f'(0).
The derivative of the function at this point is negative, which tells us <em>the function is decreasing at that point</em>.
The tangent to the line is a straight line, so we will have a linear equation of the form y = mx + c. We know the gradient, m, is equal to -1, so
Now we need to substitute a point on the tangent into this equation to find c. We know a point when x = 0 lies on here. To find the y-coordinate of this point we need to evaluate f(0).
So the point (0, -1) lies on the tangent. Substituting into the tangent equation:
