Answer:

$1,464,000

Explanation:

The computation of the depletion expense is shown below:

Purchase price plus additional cost = $5,640,000

Extracted tons during four year period = 940,000 tons

Current year tons extracted = 244,000 tons

So,

Depletion expense = Purchase price plus additional cost ÷ extracted tons during four year period × current year tons extracted

= $5,640,000 ÷ 940,000 tons × 244,000 tons

= $1,464,000

If neuron L is repeatedly stimulated very rapidly, what change would you expect in the postsynaptic neuron
lara31 [8.8K]

If neuron L is repeatedly stimulated very rapidly, The expected changes in the postsynaptic neuron are: "(Option D). See the attached for the full question.

<h3>What is the postsynaptic neuron?</h3>

Postsynaptic neurons are the neurons that take receipt of the triggers from the synapse. The synapse is responsible for generating and transmitting electrical signals.

Thus, it is right to state that if neuron L is repeatedly stimulated very rapidly, The expected changes in the postsynaptic neuron are:

  • Several simultaneous action potentials
  • Movement farther away from the threshold.

Let $S$ be the set of complex numbers of the form $a + bi,$ where $a$ and $b$ are integers. We say that $z \in S$ is a unit if t
lakkis [162]

Answer:

Number of units possible in S are 4.

Explanation:

Given <em>S</em> is a set of complex number of the form a+bi where <em>a</em> and <em>b</em> are integers.

z\in S is a unit if w\in z exists such that zw=1.

To find:

Number of units possible = ?

Solution:

Given that:

zw = 1

Taking modulus both sides:

|zw| = |1|

Using the property that modulus of product of two complex numbers is equal to their individual modulus multiplied.

i.e.

|z_1z_2|=|z_1|.|z_2|

So,

|zw| = |1|\\\Rightarrow |zw| =|z|.|w| =1\\\Rightarrow |z|=\dfrac{1}{|w|}......... (1)

Let z=a+bi

Then modulus of z is   |z| = \sqrt{a^2+b^2}

Given that a and b are <em>integers</em>, so the equation (1) can be true only when |z| = |w| =1 (Reciprocal of 1 is 1). Modulus can be equal only when one of the following is satisfied:

(a = 1, b = 0) ,  (a = -1, b = 0), (a = 0, b = 1) OR (a = 0, b = -1)

So, the possible complex numbers can be:

1.\ 1 + 0i = 1\\2.\ -1 + 0i = -1\\3.\ 0+ 1i = i\\4.\ 0 -1i = -i

Hence, number of units possible in S are 4.

Productivity measurement is complicated by
CaHeK987 [17]
Productivity measurement is complicated by the fact the precise units of measure are often unavailable. When you are managing productivity it can vary based on each task or the person completing the tasks. Because of this, it makes it complicated for management to measure productivity as there could be no units or no comparable units to measure. Productivity is better reflected on the outcome of what they do complete versus what they do not.
