time taken is 32 days,!!!!
Answer:
32 days
Step-by-step explanation:
Men. Hours. Days
30. 6. 56
45 7. X
More men less hours: inverse relation, switch the fraction 30/45 to 45/30.
More hours less days: inverse relation, 6/7 switch to 7/6.
(45/30)*(7/6) = 56/x
7/4 = 56/x ( cross multiplication)
7x = 4*56
x = 224/7
x = 32
f(- 2) = 1
f(- 2) means what is the value of f(x) when x = - 2
From the table we can see that when x = - 2 f(x) = 1
Hence
the number of miles per hour
1.5*10^-2
You mean 15/1000 written in scientific notation?
In this case, it would be- 1.5*10^-2.
