A sample of an unknown chemical element naturally loses its mass over time. The relationship between the elapsed time ttt, in days, since the mass of the sample was initially measured, and its mass, M(t)M(t)M, left parenthesis, t, right parenthesis, in grams, is modeled by the following function: M(t)=900⋅(827)t

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

if you need just tell me and i will come to the rescue.

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
