Finding the gradient (m): The gradient is the change in y-axis over the change in x-axis Δy = -10-4= -14 Δx = 12-5=7 Δy/Δx = -14/7 = -2 Ac...
1) Draw and label the axes! x= O2 partial pressure; y= % saturation/occupancy 2) Sigmoid curve (plateau at 100%) 3) Describe the curve, i.e. r...
The line of intersection will be parallel to both planes. We can write the equations of the two planes in 'normal form' as r.(2,1,-1)=4 and r.(3,5,2)=13 respectively. We can then read off the normal vecto...
Resistance is due to the collision of free electrons with the metal ions of the conductor. When the temperture increases, the metal ions have more energy and vibrate. This increases the frequency of colli...
f(x) = 3x^3 + 2x^2 - 8x + 4
f(2) = 3(2)^3 + 2(2)^2 - 8(2) + 4
f(2) = 3(8) + 2(4) - 8(2) + 4
f(2) = 24 + 8 - 16 +4
f(2) = 20
