Part A: The total value of the loan with semi-annual compounding is $36,351.74.

Part B: The total value of the loan with quarterly compounding is $36,645.80.

Part C: The difference between the total interest accrued on each loan is $294.06, with the loan that compounds quarterly accruing more interest due to the more frequent compounding periods, which results in a higher effective interest rate over the same time period.

Part A:

To find the total value of the loan with semi-annually compounded interest, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^{ (nt) }[/tex]

Where:

A = the total amount paid

P = the principal amount borrowed

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, P = $20,000, r = 0.06 (6%), n = 2 (semi-annually compounded), and t = 10 years.

[tex]A = 20000(1 + 0.06/2)^{(2*10) } = $36,109.13[/tex]

Therefore, the total value of the loan with semi-annually compounded interest is $36,109.13.

Part B:

To find the total value of the loan with quarterly compounded interest, we use the same formula but with n = 4 (quarterly compounded):

[tex]A = 20000(1 + 0.06/4)^{(4*10)} = $36,533.71[/tex]

Therefore, the total value of the loan with quarterly compounded interest is $36,533.71.

Part C:

The difference between the total interest accrued on each loan is the difference between the total amount paid for each loan minus the principal borrowed:

For the semi-annually compounded loan:

Total interest = $36,109.13 - $20,000 = $16,109.13

For the quarterly compounded loan:

Total interest = $36,533.71 - $20,000 = $16,533.71

The difference in total interest accrued between the two loans is:

$16,533.71 - $16,109.13 = $424.58

The loan with quarterly compounded interest accrues more interest due to the higher compounding frequency.

The difference in total interest accrued between the two loans is relatively small, but over time it can add up.

Step-by-step explanation:

The area of a circle is 157 square units and the circumference of a circle is 31.4√2 units.

From the given figure, legs of triangle measure the same, that is 10 units.

Let the diameter of the circle be x.

By using Pythagoras theorem,

x²=10²+10²

x²=100+100

x²=200

x=10√2 units

Radius = 5√2 units

We know that, area of a circle = πr²

= 3.14×(5√2)²

= 3.14×50

= 157 square units

We know that, circumference of a circle = 2πr

= 2×3.14×5√2

= 31.4√2 units

Therefore, the area of a circle is 157 square units and the circumference of a circle is 31.4√2 units.

Let x be the amount invested at 9% and y be the amount invested at 6%

.According to the problem:

x + y = 11,335 ----(1) (the total amount  invested is $11,335)0.09x - 0.06y = 865.35 ----(2) (the interest earned from the amount invested at 9% exceeds the interest earned from the amount invested at 6% by $865.35)

We can use these two equations to solve for x and y.

Multiplying equation (1) by 0.06, we get

:0.06x + 0.06y = 680.10 ----(3)

Subtracting equation (3) from equation (2), we get:

0.03x = 185.25

x = 6,175

Substituting x = 6,175 into equation (1), we get:

y = 5,160

Therefore, $6,175 is invested at 9% and $5,160 is invested at 6%.

The intervals on f(x) is increasing on (-∞, 0) and (8/3, ∞), and decreasing on (0, 8/3).

The intervals on which the function f(x) = x³ − 4x² + 10 is increasing or decreasing need to find its derivative and determine its sign.

f(x) = x³ − 4x² + 10

f'(x) = 3x² − 8x

The critical points we set f'(x) = 0 and solve for x:

3x² − 8x = 0

x(3x − 8) = 0

x = 0 or x = 8/3

These are the critical points of the function.

Now we can determine the sign of f'(x) in each interval:

Interval (-∞, 0):

Choose x = -1. f'(-1)

= 3(-1)² - 8(-1)

= 11 is positive.

So f(x) is increasing on (-∞, 0).

Interval (0, 8/3):

Choose x = 1. f'(1) = 3(1)² - 8(1)

= -5 is negative.

So f(x) is decreasing on (0, 8/3).

Interval (8/3, ∞):

Choose x = 3. f'(3) = 3(3)² - 8(3)

= 19 is positive.

So f(x) is increasing on (8/3, ∞).

The requried, 20 youths use both iPhone and Samsung, and 200 youths use neither iPhone nor Samsung.

Let A be the set of youths using only iPhones, B be the set of youths using only Samsung, and C be the set of youths using both. Then, we have:

|A| = 150

|B| = 770

|A ∪ B| = 900

We want to find |C| and |A ∩ B| (which is the number of youths using both).

Using the inclusion-exclusion principle, we have:

|A ∪ B| = |A| + |B| - |A ∩ B|

900 = 150 + 770 - |A ∩ B|

|A ∩ B| = 20

So, 20 youths use both iPhone and Samsung.

To find the number of youths who use neither, we can use the fact that:

|A ∪ B ∪ C| = 1100

|A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C|

Plugging in the values we know, we get:

1100 = 150 + 770 + |C| - 20 - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C|

|C| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C| = 200

Since the number of youths using both is 20, we have:

|A ∩ C| = |B ∩ C| = |A ∩ B ∩ C| = 0

So, we can simplify the equation to:

|C| = 200

Therefore, 200 youths use neither iPhone nor Samsung.

The length of the two tied strings on the number line would be between 96 and 97.

We first need to convert both the lengths of the strings to inches, since the knot's length is given in inches.

The first string is 3 3/4 feet long, which is equivalent to 45 inches (since 1 foot = 12 inches, and 3 3/4 feet = 45 inches).

The second string is 1 1/2 yards long, which is equivalent to 54 inches (since 1 yard = 36 inches, and 1 1/2 yards = 54 inches).

The total length of the two strings before the knot is tied is 45 inches + 54 inches = 99 inches.

Subtracting the length of the knot (2 1/2 inches) from the total length of the two strings gives us:

99 inches - 2 1/2 inches = 96 1/2 inches

Therefore, the length of the two tied strings on the number line would be between 96 and 97.

Since we know that the length is closer to 97 inches than 96 inches, we can mark the length at point 97 on the number line

Step-by-step explanation:

Part A:

To find the composite function, we need to plug in the expression for s(w) into f(s):

f(s(w)) = 2s(w) + 30

= 2(40w) + 30

= 80w + 30

Therefore, the composite function that represents how many flowers Lily can expect to bloom over a certain number of weeks is f(s(w)) = 80w + 30.

Part B:

The units of measurement for the function f(s(w)) are the same as the units of measurement for f(s) and s(w). From the given information, we know that s(w) represents the number of seeds planted per week and f(s) represents the number of flowers bloomed based on the number of seeds planted. Thus, the units of measurement for f(s(w)) are "flowers" per week.

Part C:

To evaluate the composite function f(s(w)) for 35 weeks, we need to substitute w = 35 into the expression we found in Part A:

f(s(35)) = 80(35) + 30

= 2,830

Therefore, Lily can expect 2,830 flowers to bloom after planting 40 seeds per week for 35 weeks.

The solutions to the original equation are:

x = π - 3π/2 = -π/2

x = 3π/2 - 3π/2 = 0

So the values of x that satisfy the equation are -π/2 and 0.

To solve the given equation, we can use the following             trigonometric identity:

sin(A) + sin(B) = 2*sin((A+B)/2)*cos((A-B)/2)

Applying this identity to sin(3π/2+x) + sin(3π/2+x), we get:

sin(3π/2+x) + sin(3π/2+x) = 2*sin((3π/2+x + 3π/2+x)/2)cos((3π/2+x - 3π/2+x)/2)

= 2sin(3π/2+x)cos(0)

= 2(-cos(x))

Therefore, the equation can be simplified to:

-2*cos(x) = 2

Dividing both sides by -2, we get:

cos(x) = -1

This means that x is either π or 3π/2, since those are the values where cos(x) = -1.

The value of x is equal to 15.1 units.

In Mathematics and Geometry, the measure of each interior angle of a regular polygon can be calculated by using this mathematical equation:

Interior angle = [180 × (n - 2)]/n

Where:

n represents the number of sides of a regular polygon.

Since this regular polygon can be decomposed into 46 triangles, it ultimately implies that it has 46 x 3 = 138 sides.

Therefore, the value of each interior angle can be calculated as;

Interior angle = [180 × (n - 2)]/n

Interior angle = [180 × (138 - 2)]/138

Interior angle = 169.6⁰

g(x) shifts the graph vertically upward by 4 units,h(x) shifts the graph horizontally to the left by 7 units,k(x) scales the graph vertically by a factor of 20 and shifts it vertically upward by 10 units and m(x) compresses the graph horizontally by a factor of 1/4 and shifts it horizontally to the right by 1 unit.

To describe the graph of each function in terms of the graph of f(x) = 5 sin(x), we will analyze how each transformation affects the original graph.

1. g(x) = 5 sin(x) + 4:

Adding a constant value of 4 to the function f(x) shifts the graph vertically upward by 4 units. The amplitude and period of the graph remain the same.

2. h(x) = 5 sin(x + 7):

Adding a constant value of 7 inside the sine function causes a horizontal shift to the left by 7 units. This means the graph is shifted 7 units in the opposite direction of the sign (left in this case). The amplitude and period remain unchanged.

3. k(x) = 20 sin(x) + 10:

Multiplying the entire function by a constant of 20 scales the graph vertically, stretching it vertically by a factor of 20. Additionally, adding a constant value of 10 shifts the graph vertically upward by 10 units.

The amplitude remains the same, but the graph is vertically elongated and shifted upward.

4. m(x) = 5 sin(4x - 1):

Inside the sine function, the value of 4 stretches the graph horizontally by a factor of 1/4. This results in a shorter period, meaning the graph oscillates more frequently.

The value of -1 inside the sine function causes a horizontal shift to the right by 1 unit. Therefore, the graph is compressed horizontally and shifted 1 unit to the right. The amplitude remains the same.

Let's call the number Kofi thinks of "x".

According to the problem Kofi adds 5 to this number and then multiplies the result by 3.

We can write this as:

3(x + 5)

We know that this expression cannot be greater than 21 so we can set up an inequality:

3(x + 5) ≤ 21

Simplifying the inequality, we get:

x + 5 ≤ 7

Subtracting 5 from both sides, we get:

The factorization of p(x) is p(x) = (x + 5)^2 (x - 3).

There are different methods to find the zeros of a polynomial, but one common approach is to use the Rational Root Theorem to test possible rational roots and then use polynomial division to factor out the roots found.

The Rational Root Theorem states that if a polynomial with integer coefficients has a rational root p/q (where p and q are integers with no common factors other than 1), then p must divide the constant term and q must divide the leading coefficient.

In the case of p(x) = x³ + x² + 8x - 60, the constant term is -60 and the leading coefficient is 1, so the possible rational roots are of the form p/q, where p is a factor of -60 and q is a factor of 1. Therefore, the possible rational roots are ±1, ±2, ±3, ±4, ±5, ±6, ±10, ±12, ±15, ±20, ±30, ±60.

Since the remainder is not zero, x = 1 is not a root of p(x). We can repeat this process with each possible root until we find all the actual roots.

Using this method, we find that the zeros of p(x) are:

x = -5 (with multiplicity 2) and x = 3.

Therefore, the factorization of p(x) is:

p(x) = (x + 5)² (x - 3)
