c) 
Step-by-step explanation:
Given the curve
a) If the x-coordinate of P is 
, then the y-coordinate is 
so point P has coordinates 
If the x-coordinate of Q is 
, then the y-coordinate is 
so point Q has coordinates 
b) The gradient of the secant RQ is
c) If 
then the gradient 
Answer:
75
Step-by-step explanation:
Let full marks be x
Then pass marks is 40% of x which is 0.4x
As per given, we have
22= 0.4x - 8
Solving for x
0.4x = 30
x = 30/0.4
x = 75
So full marks is 75
Thats good for Alex?
