So , the solution set is S={0,-
}
a) You are given the rate as 7.4m/min,
The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.
b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.
c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:
41.36 = 7.4t
To solve for t, divide both sides by 7.4:
t = 41.36 / 7.4
t = 5.59 minutes ( 5 minutes and 35 seconds)
Answer:
The equation of the line in point slope form is equal to
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of a line in point-slope form is equal to
we have
Convert to point slope form
Factor 3 left side and factor 4 right side
Divide by 3 both sides
In this equation
the point is (-2,4)
the slope is
using a graphing tool
