Answer:
5(x-3)
Step-by-step explanation:
5(x - 3)
= 5*x - 5*3
= 5x - 15
Assuming one electrician-day is the same as another, the total job is ...
... (18 electricians)×(35 days) = 630 electrician·days
When that work is split among 28 electricians, it can be expected to take ...
... (630 electrician·days)/(28 electricians) = 22.5 days
Answer:
The given function is
f(x)=cos 3x-7 x²+ 4x
f'(x)=-3 sin 3 x-14 x+4
When you will draw the graph of the function , you will find that root of the function lie between (-1,0).
Consider initial root as,
Using Newton method to find the roots of the equation
So, root of the equation is
=0.1688878
=0.1689(approx)
Answer:
Step-by-step explanation:
It would be more obvious if it says z is a standard Normal variable and that the question is related to statistics.
From "Computing Probabilities Using the Cumulative Table" , the probability of z is less than 1.16, P(z<1.16) = 0.8770.
