I think he will need around 5.69 gallons of paint
Step-by-step explanation:
<u>Part 1</u>
The gradient of the line is , so the equation is .
This means the system is
<u>Part 2</u>
Substituting in the coordinates (-3,11) and (2,1) into the equation of the parabola,
Subtracting the equations, we get 10=5a, and thus a = 2
Substituting a = 2 back into the system, we get b = -7
<u>Part 3</u>
The equation of the parabola is , and the turning point is at . Therefore, the value of y is -7
