It seems appropriate to use the linear regression function of your calculator for this. Looking at the data, you know the slope is generally positive, so only the 1st and 3rd choices are potentially viable.

A calculator shows the correlation coefficient (r) rounds to 0.816, so the appropriate selection is ...
A. 0.816

If y = 4x3 + 4x and dx dt = 3, find dy dt when x = 2.

Eva8 [605]

Dy/dx = dy/dt / dx/dt

dy/dx = 12x^2 + 4

when x = 2 , dydx = 52

52 = dy/dt / 3

so dy/dt = 156 (answer)

Whats the 11th term of 2,6,18,54

Natalija [7]

The 11th term would be 39,366.

The rule for this sequence is 3n (n times 3). Simplying multiplying by 3 until you get to the 11th term (54 * 3 * 3 * 3 * 3 * 3 * 3), would give you this answer.

I hope this helps!!
