Half life question? P(t)=100(1.2)^-t

so, im stuck on this question...please help me, thanks! a radioactive material decays exponentially. the percent, P, of the material left after t years is given by P(t)=100(1.2)^-t. a) determine the h

Ind the slope and y-intercept of the line 4x - 2y = 24

a.) m = 8, y = 1 / 2b.) m = - 2, y = 12c.) m = 12, y = - ( 1 / 2 )d.) m = 2, y = - 12-you want the form : y=mx+b so organizing into this form: 2y = 4x - 24 y = 2x - 12 m = 2 b = -12 so D-ans is

An amusement park charges $14.00 admission and $3.00 per ride. Choose the equation that models that situation.

a.) y = 14 - 3xb.) y = 14x +3c.) y = 3x + 14d.) y = 3 - 14x-C-An amusement park charges $14.00 admission and $3.00 per ride. The equation that models that situation: c.) y = 3x + 14-the answer is C
