Suppose pollutants are leaking out of an underground storage tank at a rate of latex: r\left(t\right)r ( t ) gallons per day, where latex: tt is measured in days. it is conjectured that latex: r\left(t\right)=t\cdot e^{\frac{t}{2}}r ( t ) = t ⋅ e t 2 during the first 7 days of the environmental disaster. how much of the pollutant leaks during the two-day time interval latex: 4\le t\le64 ≤ t ≤ 6?

we need more info to solve this

what is all that apply?

the answer is c.

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
