If you ignore friction, the amount of time required for a box to slide down an inclined plane is square root of 2a/g sin theta cos theta
where a is the horizontal distance defined by the inclined plane, g is the acceleration due to gravity and

theta

is the angle of the inclined plane. For what values of

theta

is the expression undefined?

a. 0°

b. 90°

c. both a and b

d. none

Apatient is given 50 mg dose of medicine the medicines effectiveness decreases every hour at a constant rate of 40% what is the exponential decay function that models this scenario how much medicine will be left in the patients system after 2 hours

If you can solve all of these i will give ! - 4% of 190 - 4% of 162.5 - 4% of 140 - a 4% increase from 155.1 - a 4% increase from 159.8
