You are driving a delivery truck that is less than 40 years old, with a net weight of 22,500 pounds. The Florida seat belt law
A: Requires the driver to wear a seat belt, but the front seat passengers are not required to wear seat
belts.
B: Requires that the front seat passengers wear seat belts, but the driver is not required to wear a
seat belt
C: Requires the driver and all front seat passengers to wear seat belts.

What are the choices?

Manual pipetting creates a musculoskeletal load on the neck, shoulders, and upper limbs and the type of injuries that this can lead to is called repetitive stress injuries.

You need to figure out at which x-value does the graph has a tangent line slope of -1.remember, the derivative is the slope of the tangent line. so find the derivative function and set it to equal -1 to find the x-value that will have a tangent line slope of 0.differentiate with the chain rule.    set the derivative to equal -1 and solve for x.      take log base 10 of both sides. also recall that  .    so the x-coord of the point of tangency is .the y-coordinate of this point of tangency can be calculated using the original function:     using point-slope form, the equation of the tangent line is      the x-intercept of this tangent line is when the graph is at y=0.    this rounds off to  .choice c.
