Answer:
S'(t) = 0.09t^2 + t + 9
S(2) = 24.24
S'(2) = 11.36
S(11) = 203.43 means that the sales of the company 11 months from now is $203,430,000.
S'(11) = 30.89 means that, 11 months from now, the rate at which sales change is $30,890,000 per month
Step-by-step explanation:
The derivate of the sales function S'(t) , which is the rate at which sales vary with time in months, is:
S(2) is found by applying t=2 to S(t):
S'(2) is found by applying t=2 to S'(t):
Since the sales function gives the amount of sales in millions of dollars,
S(11) = 203.43 means that the sales of the company 11 months from now is $203,430,000.
S'(t) represents the rate of change in sales in millions of dollars per month.
S'(11) = 30.89 means that, 11 months from now, the rate at which sales change is $30,890,000 per month
So, Both lines are perpendicular
Step-by-step explanation:
We need to identify if lines:
Line 1: (8,12)(7,-5)
Line 2: (-9,3)(8,2)
are parallel, perpendicular, or neither?
- Lines are parallel if they have same slopes i.e slope 1= slope2
- Lines are perpendicular if their slopes are negative inverses of each other i.e slope 1= -1/slope 2
The formula used to find slope is:
Finding Slope of Line 1:
The points are: Line 1: (8,12)(7,-5)
Putting values in the formula:
So, Slope of line 1 is 17
Finding Slope of Line 2:
The points are: Line 2: (-9,3)(8,2)
Putting values in the formula:
So, Slope of line 2 is
Since
So, Both lines are perpendicular
