Answer:

C

Step-by-step explanation:

The vertex form for a parabola is a(x-h)^2 + k, where h is the x coordinate of the vertex and k is the y coordinate. a represents the amount that the graph has been "squeezed". Therefore, since the coordinates of the vertex of this parabola are (2,4), and it is "squeezed" by a factor of 2, the correct answer is C. Hope this helps!

Initially 100 milligrams of a radioactive substance was present. After 6 hours the mass had decreased by 2%. If the rate of deca

The amount of radioactive material remaining after 24 hours is 92.15 kg.

<h3>Exponential function</h3>

An exponential function is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

Let y represent the amount of the substance after t hours.

From the equation, a = 100 mg

Also, after 6 hours:

100-100*2\%=100b^6\\\\98=100b^6\\\\b=0.9966

After 24 hours:

y = 100(0.9966)²⁴ = 92.15 kg

The amount of radioactive material remaining after 24 hours is 92.15 kg.
