calculus
Give a possible formula for the illustrated function using a vertical shift of an exponential function. The two points marked on the graph are A=(−172) and B=(10). The red horizontal line is given by y=−3, and is a horizontal asymptote of the function y=?

Acid-base titration
A weak acid HA (pKa = 5.00) was titrated with 1.00 M KOH. The acid solution had a volume of 100.0 mL and a molarity of 0.100 M. Find the pH at the following volumes of base added and make a graph of pH versus Vb: Vb = 0, 1, 5, 9, 9.9, 10, 10.1, and 12 mL.

physics
A puck on a horizontal, frictionless surface is attached to a string that wraps around a pole of finite radius, as shown in the figure . As the puck moves along the spiral path, does its speed increase, decrease, or stay the same?

physics
A 19.2-kg box rests on a frictionless ramp with a 16.1° slope. The mover pulls on a rope attached to the box to pull it up the incline. If the rope makes an angle of 43.6° with the horizontal, what is the smallest force F the mover will have to exert to move the box up...

I took college levels classes AT A COLLEGE beginning when I was 13 years old and I accumulated over 40 credits toward college before I was 18 years old. Don't let anyone tell you you can't understand college materials. Before you search the text of your textbook for an...

Physics
A positive charge Q is on the y-axis at a distance a from the origin, and another positive charge q is on the x-axis at a distance b from the origin. A) For what values(s) of b is the x-component of the force on q a minimum? B) For what values(s) of b is the x-component of the...
