b. What is the voltage gain Av obtained? (Answer with a whole number rounded)
c. For the cascade connection, find the open circuit voltage gain. (Respond with a rounded integer)
d. If you have a 1.5 mV input, What is the efficiency of the equivalent amplifier?
e. Find the transconductance of the entire circuit.

Paul purchased a new office computer system on February 15, 2016, at a cost of 8300. He would like to use the General Depreciation System (GDS) straight-line method to depreciate the system and does not want to claim bonus depreciation. Using the half-year convention, compute his 2016 and 2017 depreciation. a. His 2016 Depreciation is $1,660, and his 2017 is $2,656 b. His 2016 is $1453 and 2017 is $1660. c. 2016 is $830 and 2017 is $1660 d. 2016 is $691 and 2017 is $1,384

Chambers Delivery Company purchased a new delivery truck for $46,200 on April 1, 2016. The truck is expected to have a service life of 10 years or 130,800 miles and a residual value of $4,680. The truck was driven 9,700 miles in 2016 and 13,400 miles in 2017. Chambers computes depreciation to the nearest whole month.

The book value of the asset in the early years of the asset's service will be(about the same, higher, or lower) under an accelerated method as compared to the straight-line method. The (activity, double declining,sum of , straight) method is appropriate when the service life of the asset is affected primarily by the amount the asset is used.

Write a function that will accept one integer matrix E and one column vector F by reference parameters, and one integer I as a value parameter. The function will return an integer v, which is the i-th coefficient of row vector denoted by E*F (multiplication of E and F). For example, if V = E*F, the function will return v, which is equal to V[i].
Explain the time complexity of this function inside of the function code as a comment.

Let T,S : V → W be two linear transformations, and suppose B1 = {v1,...,vn} andB2 = {w1,...,wm} are bases of V and W, respectively.
(c) Show that the vector spaces L(V,W) and Matm×n(F) are isomorphic. (Hint: the function MB1,B2 : L(V,W) → Matm×n(F) is linear by (a) and (b). Show that it is a bijection. A linear transformation is uniquely specified by its action on a basis.)
