6 because 5 or more raise the score 4 or less let it rest.
ANSWER
a) £1350
b)£235
c)108°
EXPLANATION
The angle that corresponds to Andrew is 72°
The total angle in the circle is 360°
If 72° corresponds to £270,
Then, 360° corresponds to:
=£1350
Therefore the total weekly income of the 5 employees is £1350.
b) The angle that corresponds to Brian's income is 62°
Brian's weekly income is
=£225
c) Carol's weekly income is £405
Let x represent the angle representing Carol's weekly income.

Area of a Region Formula:
Step-by-step explanation:
*Note:
<em>Remember that for the Area of a Region, it is top function minus bottom function.</em>
<em>Also remember that finding area and evaluating are two different things.</em>
<u>Step 1: Define</u>
f(x) = x
g(x) = x³
Bounded (Partitioned) by x-axis
<u>Step 2: Identify Bounds of Integration</u>
<em>Find where the functions intersect (x-values) to determine the bounds of integration.</em>
Simply graph the functions to see where the functions intersect (See Graph Attachment).
Interval: [-1, 1]
1st Integral: [-1, 0]
2nd Integral: [0, 1]
