Answer:
108.7 ft
Step-by-step explanation:
Put 30 where x is and do the arithmetic.
y = -3.29·30 -10 = -98.7 -10 = -108.7
The trend line predicts the depth to be 108.7 ft after 30 minutes.

<em>Comment on this problem</em>
Real-world considerations in scuba diving may cause the diver to level off or head toward the surface before 30 minutes elapse. The trend line does not model these effects.
The graph that represents the equation f(x) = 3(2)^x is graph c
<h3>How to determine the graph?</h3>
The equation of the function is given as
f(x) = 3(2)^x
The above equation is an exponential function
An exponential function is represented as
f(x) = ab^x
Where
- a represents the y-intercept
- b represents the rate
By comparing the equations, we have
a = 3 and b = 2
This means that the graph cross the y-axis at y = 3 and the graph is a growth function
The graph that shows the above highlight is graph (c)
