Length of tree = 8.57 m.

Let AB represent the length of lower CD represent the length of tree.

Now we use the trigonometric ratios formula

tan = Perpendicular / base.

Now, in triangle AEC

tan 28° = AE / EC = AE / 44

= AE = 44 * Tan 28^.

= AE = 23.39 m

Now, in triangle ABD.

Length of tree = Length of  tower

= Length of tree = 31.97 – 23.39

= Length of tree = 8.57 m.

Pythagoras of Samos became an historic Ionian Greek logician and the eponymous founder of Pythagoreanism. His political and religious teachings were widely recognized in Magna Graecia and motivated the philosophies of Plato, Aristotle, and, through them, the West in preferred. knowledge of his life is clouded with the aid of legend; however, he appears to have been the son of Menarches, a gem-engraver at the island of Samos. cutting-edge students disagree concerning Pythagoras's schooling and influences; however, they do agree that, around 530 BC, he travelled to Croton in southern Italy, wherein he based a school in which initiates have been sworn to secrecy and lived a communal, ascetic lifestyle.

This lifestyle entailed some of dietary prohibitions, historically said to have included vegetarianism, despite the fact that current students doubt that he ever encouraged entire vegetarianism. The coaching most securely recognized with Pythagoras is metempsychosis, or the "transmigration of souls", which holds that every soul is immortal and, upon demise, enters into a new body.

The price per unit that yields maximum revenue is $400.

We can start by finding the demand function for the product. Since the demand is assumed to be linear, we can use two data points to find the equation of the line:

(40, 300) and (45, 275)

Using the point-slope form of a line, we get:

(275 - 300) / (45 - 40) = -5/25 = -1/5

y - 300 = (-1/5)(x - 40)

y = (-1/5)x + 320

where y is the number of units sold per week and x is the price per unit.

The revenue function is simply the product of the price and the number of units sold:

R = xy

Substituting the demand function, we get:

R = x(-1/5)x + 320x

Simplifying, we get:

R = -1/5x^2 + 320x

To find the price per unit that yields maximum revenue, we need to take the derivative of the revenue function with respect to x and set it equal to zero:

dR/dx = -2/5x + 320 = 0

Solving for x, we get:

x = 800/2 = $400

The gross pay for the given service is $343.2.

Gross pay is what employees earn before taxes, benefits and other payroll deductions are withheld from their wages.

Given that, the regular salary of some service is $7.80 per hour, we need to calculate the gross payment with over time hour, which is 4 hours and regular hour of work is 40 hours.

Therefore,

To find, gross payment, we will multiply by 7.80 by 4 and 40, and add both to get the regular salary,

Gross payment = 7.80 × 4 + 7.80 × 40  

= 7.80(4+40)

= 7.80 × 44

= 343.2

Hence, the gross pay is $343.2

Step-by-step explanation:

the surface areas are always the sum of the areas of the individual sides and base area.

so, all we need to do here is calculating the areas of triangles, rectangles (actually squares) and a hexagon.

the area of a triangle is

baseline × height / 2

or with Heron's formula when we have all sides

s = (a+b+c)/2

area = sqrt(s×(s-a)×(s-b)×(s-c))

the area of a rectangle is

length × width

for a square that is then

side × side = side²

and the area of a regular hexagon can be created again as sum of multiple sub-shapes. but ultimately it is

3 × sqrt(3) × side² / 2

square base area : 10×10 = 100 cm²

lateral areas :

one triangle is 10×13/2 = 65 cm²

4 triangles are then 4×65 = 260 cm²

total surface area :

100 + 260 = 360 cm²

3 lateral triangles :

3 × 8×10/2 = 120 units²

base area (Heron's, as all 3 sides are 8 units) :

s = 3×8/2 = 12

area = sqrt(12×4×4×4) = sqrt(3×4×4×4×4) = 16×sqrt(3)

total surface area :

The length of the vector function F(t) over the interval -6 ≤ t ≤ 8 is  D) L = 14√56.

The length of the vector function F(t) = <3 - 4t, 6t, -(9 + 2t)> from -6 ≤ t ≤ 8, we need to calculate the integral of the magnitude of the derivative of F(t) with respect to t over the given interval.

The magnitude of a vector v = <x, y, z> is given by ||v|| = √(x² + y² + z²).

First, let's find the derivative of F(t):

F'(t) = <-4, 6, -2>

Next, let's find the magnitude of F'(t):

||F'(t)|| = √((-4)² + 6² + (-2)²)

= √(16 + 36 + 4)

= √56

Now, we can calculate the length of F(t) over the interval -6 ≤ t ≤ 8 by integrating ||F'(t)|| with respect to t:

L = ∫(√56) dt

= √56 ∫dt

= √56 × t + C

Evaluating the integral over the given interval:

L = √56 × t + C| (-6)⁸

= √56 × (8 - (-6))

= √56 × 14

= 14√56

Therefore, the length of the vector function F(t) over the interval -6 ≤ t ≤ 8 is 14√56.

The length of TU in circle D is 5.1 units.

One important property is that if a chord is perpendicular to a radius, then it bisects the radius. In other words, if we draw a radius from the center of the circle to the midpoint of the chord, it will be perpendicular to the chord.In this case, we can see that chord TU is perpendicular to radius OD, because both of them pass through point U. Therefore, TU must bisect OD, and we can use the Pythagorean theorem to find its length.

We will apply the Pythagorean Theorem to the right triangle TUV. We know that TV is the radius of circle D, which is 3.4 units. We also know that UV is 3.8 units, as given in the diagram. Using the Pythagorean Theorem, we can find that:

TU^2 = TV^2 - UV^2

TU^2 = 3.4^2 - 3.8^2

TU^2 = 5.76

TU = sqrt(5.76) = 2.4*sqrt(3) = 5.1 (approx.)

Therefore, the length of TU in circle D is 5.1 units.

\(\qquad \sf  \dashrightarrow \: 20x - 8 = 18x + 6\)

\(\qquad \sf  \dashrightarrow \: 20x - 18x = 6 + 8\)

\(\qquad \sf  \dashrightarrow \: 2x = 14\)

\(\qquad \sf  \dashrightarrow \: x = 14 \div 2\)

\(\qquad \sf  \dashrightarrow \: x = 7\)

Therefore value of x is 7

By solving the linear equation, we will see that the solution is x = 7.

Here we need to solve the equation:

\(4*(5x - 2) = 2*(9x + 3)\)

First, we should distribute the two products to get:

\(4*5x - 4*2 = 2*9x + 2*3\\\\20x - 8 = 18x + 6\)

Now we move the terms with x to the left, and the terms without x to the right.

\(20x - 8 = 18x + 6\\\\20x - 18x = 6 + 8\\\\2x = 14\\\\\)

Now we can divide both sides by 2 to get:

\(x = 14/2 = 7\\x = 7\)

So the solution of the linear equation is x = 7.

The monthly payment amount for financing the $17,000 car over 5 years with a 5% interest rate compounded monthly is approximately $321.58. The total interest paid on the loan is $2,294.80.

To find the payment amount for financing the $17,000 car over 5 years with a 5% interest rate compounded monthly, we can use the formula for the monthly payment amount on a loan.

The formula is:

PMT = PV * (r * (1 + r)^n) / ((1 + r)^n - 1)

Where:

PMT is the monthly payment amount

PV is the present value of the loan

r is the monthly interest rate

n is the total number of monthly payments

Given:

PV = $17,000 (the amount to finance)

r = 5% / 100 / 12 = 0.004167 (monthly interest rate)

n = 5 years * 12 months/year = 60 months

Substituting these values into the formula:

PMT = $17,000 * (0.004167 * (1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)

Using a calculator or spreadsheet software, we can calculate the monthly

payment amount to be approximately $321.58.

(b) To find the total interest paid over the 5-year period, we can subtract the principal amount (PV) from the total amount paid over the term of the loan. The total amount paid is simply the monthly payment amount (PMT) multiplied by the number of monthly payments (n).

Total amount paid = PMT * n = $321.58 * 60 = $19,294.80

Total interest paid = Total amount paid - Principal amount

Total interest paid = $19,294.80 - $17,000 = $2,294.80

Therefore, the total interest paid on the loan is $2,294.80.
