If I were to get the job, I would get a writing board to help explain this. But to approach this question, it's a good idea to draw the graph. You know that the tangent line is a straight line and as the ...

Using the sine rule it's possible to find the length opposite to the 72° angle. Therefore: 5/(sin63)=x/(sin72) x=5sin(72)/sin(63)=5.34 At this point, the third angle is needed. Since a triangle has a tota...

y = (2e-6)x + 6

K = C + 8 → C = K - 8

J = K + 5

J + K + C = 72

(K + 5) + K + (K - 8) = 72

3K - 3 = 72

3K = 75

K = 25

J = 25 + 5 = 30

C = 25 - 8 = 17

The chain rule is the technique used for differentiation when the equation you're trying to differentiate contains a function of a function. Consider ln(x). You should know this differentiates to 1/x. If ...
