If a manufacturer sells x units of a certain product, his revenue R and cost C (in dollars) are given by R = 24x
C = 3800 + 6x + 0.004x^2
Use the fact that
profit = revenue − cost
to determine how many units the manufacturer should sell to enjoy a profit of at least $4200.
The manufacturer must sell a minimum of how many units and a maximum of how many units to enjoy a profit of at least $4200.?

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

answer: 193

explanation:

200-7 = 193

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

other answer is correct. i had used the radius of the radius somehow. a website:
