The supply equation of the company's total cost is 0.75x

The question implies that we determine the equation of the company production and categorize the equation as demand or supply

The given parameters are:

The total cost of production is calculated as:

Total Cost = Overalls * Cost price

To determine the equation, we set the number of overalls to x.

So, we have:

Total Cost = x * 0.75

Evaluate

Total Cost = 0.75x

Hence, the equation of the company's total cost is 0.75x

The balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is $372,134.19.

The future value refers to the compounded future value of an asset, for example, a pension plan, based on a growth rate of interest for a future period.

The future value can be determined with the FV formula, table, or using an online finance calculator as follows:

N (# of periods) = 528 months (68 - 24 x 12 months)

I/Y (Interest per year) = 6%

PV (Present Value) = $0

PMT (Periodic Payment) = $144

Results:

FV = $372,134.19

Sum of all periodic payments = $76,032 ($144 x 528)

Total Interest = $296,102.19

Thus, the balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is $372,134.19.

The production quantity of 40,000 units, it is estimated that 38,000 units will be sold and 2,000 units will be salvaged. For the production quantity of 80,000 units, it is estimated that 64,000 units will be sold and 16,000 units will be salvaged.

Based on the information provided, let's analyze the production quantities of 40,000 units and 80,000 units, considering the assumptions for product sales and salvage.

40,000 unit plan:

Sold: 95% of 40,000 units = 0.95 * 40,000 = 38,000 units

Salvaged: 5% of 40,000 units = 0.05 * 40,000 = 2,000 units

80,000 unit plan:

Sold: 80% of 80,000 units = 0.80 * 80,000 = 64,000 units

Salvaged: 20% of 80,000 units = 0.20 * 80,000 = 16,000 units

Therefore, for the production quantity of 40,000 units, it is estimated that 38,000 units will be sold and 2,000 units will be salvaged.

For the production quantity of 80,000 units, it is estimated that 64,000 units will be sold and 16,000 units will be salvaged.

The domain of f(x) is all real numbers > than it equal to 3, for f(x) = 3/x + 2 - √(x - 3).

The domain of a function f(x) is the set of all real values of x, for which real f(x) exists.

In the question, we are asked to find the domain of the function f(x) = 3/x + 2 - √(x - 3).

To find the domain of f(x), we need to check the real values of x, for which real f(x) exists.

We check each part of f(x):

For 3/x, every x gives a real value except x = 0.

For 2, every x gives a real value as it is not dependent on x.

For √(x - 3), real values exist when x - 3 ≥ 0, as negative square roots are not real.

Therefore, after assessing each term, we can say that the domain for f(x) is x - 3 ≥ 0, or x ≥ 3.

Therefore, the domain of f(x) is all real numbers > than it equal to 3, for f(x) = 3/x + 2 - √(x - 3).

The trigonometric identity 4cos(-5B) sin3B is equivalent to 2[sin(8B) - sin(2B)]

Since we have 4cos(-5B) sin3B

Using the trigonometric identity

sin(x + y) - sin(x - y) = 2cosxsiny

So, cosxsiny = [sin(x + y) - sin(x - y)]/2

Since we have 4cos(-5B) sin3B, comparing cos(-5B) sin3B with cosxsiny, we have

x = -5B and y = 3B

So, we have cos(-5B)sin3B = [sin(-5B + 3B) - sin(-5B - 3B)]/2

= [sin(-2B) - sin(-8B)]/2

=  [-sin(2B) - {-sin(8B)}]/2 [since sin(-2B) = -sin(2B)]

=  [-sin(2B) + sin(8B)]/2

= [sin(8B) - sin(2B)]/2

So, 4cos(-5B)sin3B = 4 × [sin(8B) - sin(2B)]/2

= 2[sin(8B) - sin(2B)]

So, the trigonometric identity 4cos(-5B) sin3B is equivalent to 2[sin(8B) - sin(2B)]

Answer:

Step-by-step explanation:

Answer: a = 2√3

First method (Pythagoras theorem):

a² + b² = c²

a² + 2² = 4²

a² = 16 - 4

a = √12

a = 2√3

Second method (sine rule):

opposite/hypotenuse = sin(x)

a/4 = sin(60)

a = 4sin(60)

a = 2√3

Third method (tan rule):

opposite/adjacent = tan(x)

a/2 = tan(60)

a = 2tan(60)

a = 2√3

Answer:

2√3

Step-by-step explanation:

From inspection of the given triangle:

As we cannot be sure that ΔABC is a right triangle since it is not marked as such, use the cosine rule to find the exact length of side a.

Cosine Rule

[tex]a^2=b^2+c^2-2bc \cos A[/tex]

where a, b and c are the sides and A is the angle opposite side a

Given:

Substitute the given values into the formula and solve for a:

[tex]\implies a^2=2^2+4^2-2(2)(4) \cos 60^{\circ}[/tex]

[tex]\implies a^2=4+16-16\left(\dfrac{1}{2}\right)[/tex]

[tex]\implies a^2=20-8[/tex]

[tex]\implies a^2=12[/tex]

[tex]\implies a=\sqrt{12}[/tex]

[tex]\implies a=\sqrt{4 \cdot 3}[/tex]

[tex]\implies a=\sqrt{4}{\sqrt{3}[/tex]

[tex]\implies a=2\sqrt{3}[/tex]

Therefore, the exact length of side a is 2√3.

To find out if ΔABC is a right triangle, use Pythagoras Theorem to solve for side a:

[tex]\implies a^2+b^2=c^2[/tex]

[tex]\implies a^2+2^2=4^2[/tex]

[tex]\implies a^2+4=16[/tex]

[tex]\implies a^2=12[/tex]

[tex]\implies a=\sqrt{12}[/tex]

[tex]\implies a=2\sqrt{3}[/tex]

As the measure of side a is the same as the solution found when using the cosine rule, we can conclude that ΔABC is a right triangle.

Since the angles of elevation of the top of two vertical towers is 45° & 60°, the ratio of the height of the towers is 0.58:1

Since the angles of elevation of the top of two vertical towers as seen from the middle point of the lines joining the foot of the towers are 45° & 60°.

The height of the tower, the line of sight and the ground form a right angled trangle

Let

Using trigonometric ratios, we have that

tanФ = h/d

= h/L/2

= 2h/L

So, h = LtanФ/2

= Ltan45°/2

= L/2 × 1

= L/2

Let

Using trigonometric ratios, we have that

tanФ' = h'/d

= h'/L/2

= 2h'/L

So, h' = LtanФ'/2

= Ltan60°/2

= L/2 × √3

= √3L/2

So, the ratio of the height of the towers is n = h/h'

= L/2 ÷ √3L/2

= 1/√3

= 1/1.732

= 0.577

≅ 0.58

So, the ratio of the height of the towers is 0.58:1

The couple invested:

to earn $477 as the total interest for the first year.

The interest over an investment is the additional amount that a person receives on investing his/her money in the cause.

In the question, we are informed that in investing $6,150 of a couple's money, a financial planner put some of it into a savings account paying 6% annual simple interest. The rest was invested in a riskier mini-mall development plan paying 9% annual simple interest. The combined interest earned for the first year was $477.

We are asked to find the amount invested in each rate.

We assume the amount invested in savings account to be $x.

Therefore, the amount invested in development plan is $(6150 - x).

Simple interest on a sum of money (P), at a rate (r) over a time period (t), is given as S.I. = (Prt)/100.

We calculate the interest earned in both investments:-

Investment in savings account:

Amount invested (P) = $x.

Rate of interest (r) = 6%.

Time for investment (t) = 1 year.

Therefore, interest received = (Prt)/100 = $(x*6*1)/100 = $ (6x)/100

Investment in development plan:

Amount invested (P) = $(6150 - x).

Rate of interest (r) = 9%.

Time for investment (t) = 1 year.

Therefore, interest received = (Prt)/100 = $((6150 - x)*9*1)/100 = $ {9(6150 - x)}/100.

We know that the total interest received is $477.

Thus on adding Interests from both the investments, we can write an equation:

(6x)/100 + {9(6150 - x)}/100 = 477

or, 6x + 55350 - 9x = 47700,

or, 55350 - 47700 = 3x,

or, 3x = 7650,

or x = 7650/3 = 2550.
