In mammals, the weight of the heart is approximately 0.5% of the total body weight. write a linear model that gives the heart weight in terms of the whole body weight. use the model to fins a. the weight of a human whose weight is 183 lbs.

We have weight of heart equal to 0.5 % of body weight.

Let us take x as body weight and y as weight of heart.

We have by equation of line

            y = mx+c    , here c = 0 since weight of heart = 0 when body wight of mammal = 0

            m = 0.5/100 = 0.005

           Which means weight of heart for mammals, y = 0.005 * x

           In case of humans, we have x = 183 lbs

           So weight of heart of humans = 0.005* 183 = 0.915 lbs

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
