Answer:
113.04
Step-by-step explanation:
area is πr², so 3.14·6²·3.14 = 113.04
Answer:
P = 15a + 8b
Step-by-step explanation:
Profit is 15 on each of the 'a' units of A, and is 8 on each of the 'b' units of B. Hence the total profit (P) is ...
P = 15a +8b
If your objective is to maximize profit, the objective function is ...
P = 15a +8b
The path of the car and the limo are straight lines.
To determine the equation of the lines of the paths, the slopes must be determined.
Let m1 = slope of car
m2 = slope of limo
so,
m1 = (7 + 7)/(5 + 2) = 2
m2 = (-5 -9)/(3+4) = -2
therefore the equations are
car:
2x – y = 2(5) –(7)
2x – y = 3
Limo:
2x + y = 2(3) – 5
2x + y = 1
Solving the intersection of the equations (using a calculator)
x = 1
y = -1
