Using an exponential function, it is found that 4 mg of the substance would still be left after 32 days.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, considering that the initial amount if of 64 mg, and we are working with half-lifes, the equation is given by:
32 days is 32/8 = 4 half-lifes, hence the amount remaining in mg is given by:

(5,9) (8,33)
(33-9)/(8-5)= 24/3= 8
y-9= 8(x-5)
y-9= 8x-40
y= 8x-31
Answer:
This is a curve linear would show the turning points clearly.
With bar graph we can also show changes but not turnng points a sthe description shows.
Step-by-step explanation:
In the context of curve fitting, a linear curve is a curve that has a linear dependence on the curve parameters. Examples of linear curves are: lines, polynomials, so where they increase the points can also show a line of fit where least amounts would stand out below the line of fit.
A = 1/2 (base * height)
A = 1/2 [(x^2 + 2x + 4)*(<span>2x^2 + 2x + 6)]</span>
