Question 8

+2 marksNumerical answer

A satellite dish is shaped like a parabola, and its height above the ground (in meters) at a horizontal position $x$ meters is given by

$f(x) = ax^2 - 12x + 10, \quad a \in \mathbb{R} \setminus \{0\}.$

An engineer places a ladder that follows the path of a line given by $y = 8x + 3$ . At the point where $x = 1$ , the slope of the satellite dish's curve is the same as the slope of the ladder.

Use this information to answer the given subquestions.
