Answer:
Step-by-step explanation:
Roots of the equation are -4 and -3.
Quadratic equation can be written as
Answer:
1. Yes, the lines are perpendicular.
2.
Step-by-step explanation:
The first equation of Exercise 1 is incomplete. Let's assume that it is:
Where "n" is a number.
First, it is important to remember that the equation of a line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
By definition, the slopes of perpendicular lines are negative reciprocals.
1 . If you solve for "y" from the first equation, you get:
You can identify that the slope is:
The second equation of the line is:
And its slope is:
Since the slopes are negative reciprocals, the lines are perpendicular.
2. Given the first equation of the line:
You can identify that:
Since the first line and the second one are perpendicular, you know that the slope of the other line is:
According to the information given in the exercise, both lines have the same y-intercept; therefore, the equation of the second line is:
Answer:
6 years
Step-by-step explanation:
we know that
The equation of a exponential growth is equal to
where
y ----> is the population
x ---> is the number of years since now
a ---> is the initial value or y-intercept
r ---> is the rate of change
we have
substitute
For y=19,600
substitute in the exponential equation and solve for x
apply log booth sides
