<h2>Hello!</h2>
The answer is: 50% (0.5)
<h2>Why?</h2>Exponential growth equations are use to predict the growth (in function of time) using proportional information.
We can calculate the exponential growth using the following formula:
Where,
S, is the starting value
r, is the growth rate
t, is the time
So, we are given the function:
Where,
f(t), is the function,
3, is the starting value (lb)
0.5 (50%) is the growth rate
nt, is the time elapsed.
Hence,
From the given function, we know that the growth rate is equal to 0.5, and it's equal to 50%.
We can turn the growth rate given in real numbers to percent value by multiplying by 100
So, the growth rate is 50%.
Have a nice day!
Option C. The statement that describes the graph of the equation y + 2 ≥ –4(x – 3)2 is a a parabola opening down, with shading above the vertex.
<h3>How to describe the shape of the parabola.</h3>To do this you have to create a graph of the equation as seen in the attachment.
From the attachment we can see that the parabola is shaped downwards while we have the shading to be at the top of the vertex.
