For the function y=400-18x, find the rate of change.

The rate of change is _____

solve 124 = 3(4) ^2x-1 for x using logarithms

Let 𝑨 = 𝑏𝑥𝑖̂+ 𝑏𝑦𝑗̂+ 𝑏𝑧𝑘̂. Evaluate ∇ ∙ (∇ × 𝑨) by (1) first expressing ∇ × 𝑨 using 𝑏𝑥 etc. and 𝑖̂etc., and (2) finding
the divergence of the resultant vector.

please show all steps amd any helpful hints

thank you.

this is going to eventually apply to FEM models
