Racetrack principle
suppose that f(t) is continuous and twice-differentiable for t≥0. further suppose f″(t)≥7 for all t≥0 and f(0)=f′(0)=0.
using the racetrack principle, what linear function g(t) can we prove is less than or equal to f′(t) (for t≥0)?
g(t)=
then, also using the racetrack principle, what quadratic function h(t) can we prove is less than or equal to than f(t) (for t≥0)?
h(t)=

Which of the following is the correct ratio for converting kilograms to grams

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?
