Answer:

$\frac{\textbf{dy}}{\textbf{dx}} = \textbf{10ax}+\textbf{9bx}^2$

Step-by-step explanation:

Let

$y= 5ax^2+3bx^3+5$

Differentiating y with respect to x

$\frac{dy}{dx} =5a(2x)+3b(3x^2)+0$

$\frac{dy}{dx}= 10ax+9bx^2$ where a and b are constants

I believe the answer is 1 because the line is negative and has a slope of 1/2 so -1/2 and it crosses at 8

x = sin^-1(11.8/12)
x = 79.5 degrees (3 s.f.)
