The depreciation for the first year is $28,800.

If the equipment is sold for $8,860 at the end of year 2, the loss on the sale is $-14,180.

Depreciation is the method used in expensing the cost of an asset. The double declining method is an exponential method that is used to expense the cost of an asset.

Depreciation expense using the double declining method = Depreciation factor x cost of the asset

Depreciation factor for the double declining method = 2 x (1/useful life)

Depreciation expense in year 1 = (2 / 10) x $36,000 = $7,200

Book value at the beginning of year 2 = cost of the asset - depreciation in year 1

$36,000 - $7,200 = $28,800

Depreciation in year 2 = (2/10) x  $28,800 = $5,760

Book value at the end of year 2 = book value at the end of year 1 - depreciation in year 2

$28,800 - $5,760 = $23,040

Loss = sales price - cost price

Loss = $8,860 - $23,040 = $-14,180

To answer this question we will use The Linear Programming concept

The formula for the moose population is

The moose population in 2006 would be

We use the year 1990 as the base year for creating the equation of the moose population. We could assume that:

The moose population of the year: P(x)

The moose population in year 1990: a

The year difference to 1990: x

The linear change of the moose population: b

Hence, we could make some assumption about the relationship between each elements mentioned above, where the moose population of the year would be depends on the linear change of the population added into the original moose population in year 1990. We could write this relationship into the equation (i):

P(x) = a + bx ... (i)

Using data provided from the question, we could make some other equations and find the value of b:

P(x) = a + bx

P(4) = a + 4b = 3280 ---> year 1994 ... (ii)

P(7) = a + 7b = 4120 ---> year 1997 ... (iii)

We could do some eliminations between equations (ii) and (iii)

3280 = a + 4b

4120 = a + 7b -

840 = 3b

b = 280 ... (iv)

After finding the value of b, we could subtitute its value into equation (ii) to find the value of a:

3280 = a + 4b

3280 = a + 4(280)

3280 = a + 1120

a = 2160 ... (v)

After finding the value of a and b, we could rewrite the equation (i) by inserting the and b values.

P(x) = a + bx

P(x) = 2160 + 280x ... (vi)

Next, we will predict the moose population to be in 2006.

First, we should determine the value of x, the difference between the year 2006 to the base year 1990.

x = 2006 - 1990

x = 16 ... (vii)

We would subtitute the equation (vii) into equation (vi) to predict the moose population to be in 2006:

P(16) = 2160 + 280(16)

The value of h in the given polygon is 34.8°

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides or edges of a polygon are made of straight line segments connected end to end to form a closed shape. The point where two line segments meet is called vertex or corners, and subsequently, an angle is formed. If a polygon contains congruent sides, then that is called a regular polygon.

The sum of the interior angles of a regular polygon = (n - 2) x 180

where n = number of sides of the polygon

here n = 20

Sum of the interior angle = (20 - 2) x 180

Sum of the interior angle = 3240°

which also means that 20(5h - 12) = 3240

100h -240 = 3240

100h = 3240+240

100h = 3480

h = 3480/100

h = 34.8°

The derivative of a function of a real variable in mathematics assesses how sensitively the function's value changes in response to changes in its argument. Calculus's core tool is the derivative.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is tan(cos(t)). The derivation will be done as below,

[tex]\dfrac{d}{dx}tan(cos(t))=sec^2(cos(t)\dfrac{d}{dx}(cos(t)\\\dfrac{d}{dx}tan(cos(t))=-sin(t)sec^2(cos(t)\\\dfrac{d}{dx}tan(cos(t))=-sin(\dfrac{\pi}{2} )sec^2(cos\dfrac{\pi}{2})\\\\\dfrac{d}{dx}tan(cos(t))=sec^2(0)\\\dfrac{d}{dx}tan(cos(t))=1[/tex]

The equation of the line that passes through the point P(1/3,4) and has no slope is y = 4.

According to the question,

We have the following information:

Point through which line is passing = (1/3,4)

Slope of the line = 0

We know that the following formula is used to find the equation of the line passing through a point:

y-y' = m(x-x')

We have x' = 1/3 and y' = 4.

y-4 = 0(x-1/3)

y-4 = 0

Adding 4 on both sides of the equation:

a = 1.5, b = 4, c = -2.

Inserting these coefficients into a calculator, the x-intercepts of the function are given as follows:

The y-intercept of the function is given by coefficient c = -2, hence the function also passes through point (0, -2).

The x-coordinate of the vertex is given as follows:

Part 2. For every 2 cups of red paint, there are 7 cups of white paint.

For every 1 cup of red paint, there are 3.5 cups of white paint.

This means that we need to multiply 14 x 3.5.

14 x 3.5 = 49.

According to the concept of quadratic equation, the minimum cost for the x ray machine is $17, 484

Quadratic equation:

Basically, the polynomial equation with highest degree of two is called a quadratic equation.

The general equation is given by ax² + bx + c = 0, where a ≠ 0.

Given,

A medical equipment industry manufactures X-ray machines. The unit cost C (the cost in dollars to make each X-ray machine) depends on the number of machines made. If .x machines are made, then the unit cost is given by the function C (x)=0.5x²-320x+68,684.

Here we need to find the minimum unit cost.

Here we know that the standard form of a quadratic is given by:

=> ax² + bx + c

From this function, we have to calculate the value of x as,

=> x = -b/ 2a

While we compare the standard form with the given function,

=> C (x)=0.5x²-320x+68,684.

Then we get the value of

=> a = 0.5

=> b = -320

=> c = 68,684

So, the value of x is calculated as,

=> x = -(-320) / 2(0.5)

=> x = 320 / 1

=> x = 1

Now, we have to plug this value into original function would give us the minimum (unit cost):

=> C(320) = 0.5(320)²- 320 (320) + 68,684.

=> C(320) = 0.5(102400) - 102400 + 68, 684

=> C(320) = 51200 - 102400 + 68684

=> C(320) = 17, 484

Therefore, the minimum unit cost is $17, 484

He needs 10 litres of solution of 40% and 20 litres of 70% solution to make 30 litres of 60% acid solution.

According to the question,

We have the following information:

Gabe Amodeo, a nuclear physicist, needs 30 liters of a 60% acid solution. He currently has a 40% solution and a 70% solution.

Now, let's take x litres of 40% solution and y litres of 70% solution.

So, we have the following expressions:

x+y = 30

x = 30-y ....(1)

40x/100 + 70y/100 = 30*60/100

Dividing 100 on the numerator by 100 on denominator:

40x+70y = 1800

Dividing both sides by 10:

4x+7y = 180

Putting the value of x from equation 1:

4(30-y)+7y = 180

120-4y+7y = 180

120+3y = 180

Subtracting 120 from both the sides:

3y = 180-120

3y = 60

y = 60/3

y = 20

Now, putting this value of y in equation 1:

x = 30-y

x = 30-20

x = 10

Hence, he needs 10 litres of 40% solution and 20 litres of 70% solution to make 30 litres of 60% acid solution.
