The length of GF is 4 cm minus half the length of side FH.

To do this, we can use the fact that point S is the midpoint of FH. This means that FS = 1/2 FH. Similarly, point T is the midpoint of GH, so TG = 1/2 GH. We can now use these equalities and the fact that SG = 4 cm and HT = 6 cm to set up an equation involving FH:

SG + GF + HT = ST + TG + FH

Substituting the given values and using the fact that TG = GH - TG = GH - 1/2 GH = 1/2 GH, we get:

4 cm + GF + 6 cm = 8 cm + 1/2 GH + FH

Simplifying and substituting FS = 1/2 FH and TG = 1/2 GH, we get:

10 cm + GF = 8 cm + FS + TG

GF = 8 cm + FS + TG - 10 cm

GF = 1/2 FH - 1/2 GH

Now, substituting the values we know, we get:

GF = 1/2 FH - 1/2 GH

GF = 1/2 (FS + SH) - 1/2 (GH)

GF = 1/2 (8 cm + SH) - 1/2 (GH)

GF = 1/2 (8 cm + FS) - 1/2 (GH)

GF = 1/2 (8 cm + 1/2 GH) - 1/2 (GH)

GF = 3 cm - 1/4 GH

We can now substitute TG = 1/2 GH and solve for GH:

TG = 1/2 GH

8 cm - FS = 1/2 GH

GH = 16 cm - 2 FS

Substituting this value into the expression for GF, we get:

GF = 3 cm - 1/4 (16 cm - 2 FS)

GF = 3 cm - 4 cm + 1/2 FS

GF = 1/2 FS - 1 cm

Finally, substituting FS = 8 cm - SH, we get:

GF = 1/2 (8 cm - SH) - 1 cm

GF = 4 cm - 1/2 SH

The given Mayan number which is : :|| :|| in decimal (base 10) is 42.

The Mayan number system is a base-20 system that uses three symbols: a dot (.), a horizontal bar (|), and a shell-like symbol (:). The symbol for zero is a shell-like symbol (:).

To convert the given Mayan number to decimal (base 10), we need to understand the positional value of each symbol. Each position in the number represents a power of 20, with the rightmost position being 20⁰, the next position to the left being 20¹, and so on.

The Mayan number given, : :|| :||, can be broken down as follows:

The leftmost position has no symbol, which represents a value of 0.

The second position from the left has two shell-like symbols (:), which represents a value of 2x20¹ = 40.

The third position from the left has two horizontal bars (||), which represents a value of 2x20⁰ = 2.

The given Mayan number in decimal (base 10) is 40 + 2 = 42.

The measure of the angle m∠PQR is equal to 50° using the secant tangent angle formula. So option A is correct.

The secant tangent angle is the angle formed by a tangent and a secant that intersect outside of a circle. The measure of the secant tangent angle can be found using the following formula:

θ = 1/2 (arc EB - arc BD)

where arc EB and arc BD are the measures of the arcs intercepted by the secant and tangent, respectively.

From the question,

θ = m∠PQR

arc EB = 160°

arc BD = 60°

m∠PQR = 1/2(160° - 60°)

m∠PQR = 1/2 × 100°

m∠PQR = 50°

Therefore, the measure of the angle m∠PQR is equal to 50° using the secant tangent angle formula.

The number of residents Town A used to have is 1400, and the number of residents Town B used to have is 3600, as shown by the simple equation below.

Let x be the number of residents Town A used to have. The number of residents in Town B is:

5000 - x

We know that Town A had 12% whites and Town B had 10% whites. After the merge, the percentage of whites is 10.56%. With that in mind:

12%x+10%(5000-x) = 10.56%(5000)

0,12x + 500 - 0,1x = 528

0.02x = 28

x = 1400

Therefore, the number of residents Town A used to have is 1400. Now, the number of residents town B used to have is:

When the number of milligrams reaches 11, the drug is to be injected again. We need approximately 6.7 hours between injections.

The given function is D(h)=30[tex]e^{-0.35h[/tex], which gives the number of milligrams D(h) of the drug in the patient's bloodstream h hours after it is injected.

When the drug is injected again, the number of milligrams in the bloodstream will be 11. Therefore, we need to find the value of h that satisfies the equation:

11 = 30[tex]e^{-0.35h[/tex]

To solve for h, we can first divide both sides by 30:

11/30 = [tex]e^{-0.35h[/tex]

Next, we take the natural logarithm of both sides:

ln(11/30) = ln([tex]e^{-0.35h[/tex])

Using the property of logarithms that ln(eˣ) = x, we can simplify the right side:

ln(11/30) = -0.35h

Finally, we can solve for h by dividing both sides by -0.35 and multiplying by -1:

h = (-1/0.35)ln(11/30)

Using the Law of Cosines, the angle between the lines PX and PY is found to be approximately 101.5°. Subtracting this angle from the bearing of Y from P (125°) and the bearing of X from P (35°) gives a bearing of approximately 54.5° from X to Y.

We can use the Law of Cosines to find the angle between the lines PX and PY, and then add this angle to the bearing of X from P to find the bearing of Y from X.

Let A be the angle between the lines PX and PY, and let C be the distance between X and Y. Then we have

C² = PX² + PY² - 2(PX)(PY)cos(A)

Substituting the given values, we get

950² = 420² + PY² - 2(420)(PY)cos(A)

Solving for cos(A), we get

cos(A) = (PY^2 - 950^2 - 420^2) / (-2)(420)(950)

cos(A) = -0.186

Since A is an acute angle, we can take the inverse cosine to find its measure

A = cos⁻¹ (-0.186)

A ≈ 101.5°

The bearing of X from P is 35°, so the bearing of Y from X is

Answer: The area of one semicircle is approximately 830.53 square inches.

Step-by-step explanation:

The area of a circle is given by the formula:

A = πr²

where A is the area of the circle and r is its radius.

The radius of the circle cut out of the piece of wood is about 23 inches. Therefore, its area is:

A = πr²

A = π(23)²

The bond price at 12% maturity is $435.42, at 10% maturity is $500.00, at 8% maturity is $607.28, and at 6% maturity is $748.65. The balance at the end of 28 months is approximately $41,097,019.67.

To determine the price of the bond at different yield to maturity rates, we need to use the bond pricing formula

Bond price = (Coupon payment / (1 + YTM)¹) + (Coupon payment / (1 + YTM)²) + ... + (Coupon payment + Face value) / (1 + YTM)ⁿ

Where Coupon payment = Annual coupon rate x Face value

YTM = Yield to maturity

n = Number of years to maturity x Number of coupon payments per year

Using $1,000 as the face value and an annual coupon rate of 10%, we have

At 12% yield to maturity

Coupon payment = 0.10 x $1,000 = $100

n = 20 x 2 = 40

Bond price = ($100 / (1 + 0.12)¹) + ($100 / (1 + 0.12)²) + ... + ($100 + $1,000) / (1 + 0.12)⁴⁰

Bond price = $435.42

At 10% yield to maturity

Coupon payment = 0.10 x $1,000 = $100

n = 20 x 2 = 40

Bond price = ($100 / (1 + 0.10)¹) + ($100 / (1 + 0.10)²) + ... + ($100 + $1,000) / (1 + 0.10)⁴⁰

Bond price = $500.00

At 8% yield to maturity

Coupon payment = 0.10 x $1,000 = $100

n = 20 x 2 = 40

Bond price = ($100 / (1 + 0.08)¹) + ($100 / (1 + 0.08)²) + ... + ($100 + $1,000) / (1 + 0.08)⁴⁰

Bond price = $607.28

At 6% yield to maturity

Coupon payment = 0.10 x $1,000 = $100

n = 20 x 2 = 40

Bond price = ($100 / (1 + 0.06)¹) + ($100 / (1 + 0.06)²) + ... + ($100 + $1,000) / (1 + 0.06)⁴⁰

Bond price = $748.65

To calculate the monthly payment and balance of the loan from the bank, we can use the formula for the monthly payment of an amortizing loan

P = (r × A) / (1 - (1 + r)⁻ⁿ)

where P is the monthly payment, r is the monthly interest rate (which is the annual interest rate divided by 12), A is the loan amount, and n is the total number of months in the loan.

First, we need to calculate the values of r, A, and n

r = 0.08 / 12 = 0.00667 (monthly interest rate)

A = $50,000,000 (loan amount)

n = 5 years × 12 months/year = 60 months (total number of months in the loan)

Now, we can plug these values into the formula to calculate the monthly payment

P = (0.00667 × $50,000,000) / (1 - (1 + 0.00667)⁻⁶⁰)

P ≈ $1,029,299.29

Therefore, the monthly payment on the loan is approximately $1,029,299.29.

To find the balance at the end of 28 months, we can use the formula for the remaining balance of an amortizing loan

B = (P * (1 - (1 + r)⁻ⁿ')) / r

where B is the remaining balance, r is the monthly interest rate, P is the monthly payment, and n' is the number of months remaining in the loan (which is equal to the total number of months minus the number of months already paid).

After 28 months, the number of months remaining in the loan is

n' = 60 - 28 = 32

We can now plug the values of P, r, and n' into the formula to find the balance

B = ($1,029,299.29 × (1 - (1 + 0.00667)⁻³²)) / 0.00667

B ≈ $41,097,019.67

Therefore, the balance at the end of 28 months is approximately $41,097,019.67.
