The radius of a cylinder is 1 inch and its height is 4 inches. Estimate the volume of the cylinder using linear approximation if the radius is decreased by 0.2 in. and the height is kept constant.

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)

When 142 is added to a number the result is 64 more then 3 times the number. option 35 37 39 41

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 + 4x + 5 = 0
