Answer:
V=L(di/dt) where i is current, V=0.208
Explanation:
using expression iL(t)=5e-2t+3te-2t-2 and L=0.05H(50/1000)
V=0.05*d(5e-2t+3te-2t-2)/dt
since there is no power of e, I'll assume the power to be 1
V=0.05*(-2+3e-2)
at t=0.25
V=0.15e-0.2
V=0.208
Answer:
The Border Patrol of the United States analyzes the purchase of a new helicopter for the aerial surveillance of the border of New Mexico and Texas with the Mexican Republic. 4 years ago a similar helicopter was purchased at a cost of $ 140,000.00. with an interest rate of 7% per year. Calculate the single payment factor and the present value factor with the above data with the table and formula. Draw the flow chart.

Answer: Volume= 1.16 yd³
Explanation:
We are given the in-situ moisture content= 18% and moist unit weight= 105 pcf
First we find out the dry unit weight
Dry unit weight= Moist unit weight / (1+ moisture content)
Dry unit weight= 
Dry unit weight= 88.983 pcf
Now, to find the volume ( in terms of each cubic yard i.e 1 yd³ we have
Volume = Dry unit weight compacted / Dry unit weight (in-situ) * 1 yd³
Volume= 
Volume= 1.16 yd³
