This is homework for my Calculus class, I kind of have a god understanding about it, but would love more help!

TIA!

2. (L0 5) Use the limit definition to find the derivative ofx) = #2 5x. Show all of your work; don't skip steps. 3. (L0 7) The pressure (in atmospheres) at an ocean depth of 3 feet is given by the function P(S). What would it mean to say that P(60) = 2? What would it mean to say that P '(60) = 0.03? Include units in your explanation. 4. (L0 4) Use the table below to estimate the value of f '(4). Use your estimate to find the equation of the tangent line to too at x = 4. x o 1 2 3 4 5 f(x) 90 81 73 61 56 22 1. (L0 3, 6) Using the graph shown below, draw the line whose slopes is the average velocity from t = 2 tot: 3 and line whose slope is the instantaneous velocity at t = 2, specifying which is which. Estimate the slope of each line. position {ft} time(sec)
