HEEELPPP WILL DO ANYTHING FOR IT

1. writing an equation for an exponential function by 2. a piece of paper that is 0.6 millimeter thick is folded. write an equation for the thickness t of the paper in millimeters as a function of the number n of folds. the equation is t(n)= 3. enter an equation for the function that includes the points. (-2, 2/5) and (-1,2)

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.
