The function g(d)=600−50d represents the number of gallons of water in a tank d days after the tank is filled. what does the value 50 represent in this situation? the tank had 50 gal of water in it before it was filled. the tank had 50 gal of water in it after it was filled. the volume of the tank decreases by 50 gal every day. the volume of the tank increases by 50 gal every day.

Given that a function

g(d) = 600-50d

Here g is dependent variable and d independent variable

We have to interpret the term 50 in this situation.

g = 600-50d

600 represents the initial amount of water in the tank i.e. when d =0

Let us assume d changes by 1 day. say d+1

then new g = g' = 600-50(d+1) = 550-50d

i.e. whenever d increases by 1 unit, g decreases by 50 galons

Hence correct answer is

The volume of the tank decreases by 50 gal every day.

The volume of the tank decreases by 50 gal every day.

explanation:

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
