For a line in the form:
In this case, for the line 2x + 10y = 20 with a=2 and b=10 the slope is:
Now, two lines are perpendiculars if the slopes satisfy the following equation:
So, for the line we want the slope is:
Finally, the line pass througth the point (2, 3) with slope m=5, so the equation is:
The equation of the line is y = 5x - 7
Answer:
The exponential growth model is given by this general expression:
And the exponential model decay model is given by:
Where a the initial amount r the growth factor of rate anf t the time.
The reason with we need to add 1+r in the base of the model is because each period of time we have an increase of the initial amount by a factor of (1+r) so after n periods we will have (1+r)^n times the initial amount.
Step-by-step explanation:
In general an exponential model is given by this formula:
Where:
a = the constant, b = the base and x x the exponent.
