Answer:
Step-by-step explanation:
In the given figure, secants PA and PC are intersecting outside of the circle at point P.
PA = PB + AB = 7 + 5 = 12
PC = 14, PD =?
By the property of intersecting secants outside of a circle:

Answer:
a) The basic rate of pay is 6 sterling pounds per hour.
b) The higher rate of pay is 10 sterling pounds per hour.
Step-by-step explanation:
Both segments of the curve are first order polynomials, which means that each have constant slopes.
a) The basic rate of pay is the value of the slope (
), in sterling pounds per hour, of the line for the first 20 hours worked, that is:
(1)
Where:
- Change in hours worked, in hours.
- Change in pay, in sterling pounds.
If we know that
and
, then the basic rate is:



The basic rate of pay is 6 sterling pounds per hour.
b) By using (1), we calculate the higher rate of pay below. If we know that
and
, then the higher rate is:



The higher rate of pay is 10 sterling pounds per hour.
