Writing exponential functions from scenarios a patient is given a 50 mg dose of medicine. the medicine's 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 patient's system after 2 hours? f(x) = 50(0.40)x; 8 mg f(x) = 50(0.60)x; 18 mg f(x) = 50(40)x; 80,000 mg f(x) = 50(60)x; 180,000 mg
(raise all x's)

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45

its payment history because your score is mainly based on how consistent u are with your payment and if there on time. hope this : )
