1. AB is a tangent, the triangle is a right triangle

2. AB is  not a tangent, the triangle is not a right triangle and hence not a Pythagorean triple

3. arc RS = 100 degrees

4. arc ST =  80 degrees

5. arc RTS = 260 degrees

6. arc RST = 180degrees

7. x = 3

8. x = 7

A tangent will obey Pythagorean triple hence we have that

AB^2 = AC^2 + BC^2

1. AB^2 = 24^2 + 10^2 = 676

AB = sqrt (676) = 26. hence AB is a tangent

2. AB^2 = 8^2 + 11^2 = 185

AB = sqrt (185) = 13.6. hence AB is not a tangent

Length of arc

3. arc RS = 100 degrees (central angle equals intercepted arc)

4. arc ST = 180 - arc RS = 180 - 100 = 80 degrees

5. arc RTS = 180 + arc ST = 180 + 80 = 260 degrees

6. arc RST = 180degrees (semicircle)

Value of x

7. x + 8 = 5x - 4

8 + 4 = 5x - x

12 = 4x

x = 3

8. 4x + 5 = 6x - 9

4x - 6x = -9 - 5

-2x = -14

The radius of the circle is 36 centimetres.

The circumference of the circle is  75.36 centimetres.

Let's find the radius of the circle with 20 degrees arc and length of 4π centimetres.

Length of an arc = ∅ / 360 × 2πr

where

Therefore,

Length of an arc  = 20 / 360 × 2 × π × r

4π = 40πr / 360

4π = 1 / 9 πr

cross multiply

πr = 36π

divide both sides by π

r = 36 centimetres

radius = 36 centimetres

b.

The equilateral triangle is inscribed in the circle. Therefore, the circumference of the circle can be found as follows:

The radius of the circle can be found using trigonometric ratios as follows:

The radius is an angle bisector. Hence,

sin 30 = opposite / hypotenuse

0.5 = 6 / r

cross multiply

r = 6 / 0.5

r = 12 centimetres

Lets' find the circumference,

circumference of the circle = 2πr

circumference of the circle = 2 × π × 12

circumference of the circle = 24 × 3.14

Solution: 11/5 as a mixed number is 2 1/5.

The value of sin 75 without using a calculator is 1/4(√2 +√6)

From the question, we have the following parameters that can be used in our computation:

sin(75)

This can be expanded as

sin(75) = sin(45 + 30)

Using the sine rule, we have

sin(75) = sin(45)sin(30) + cos(45)cos(30)

Evaluate the trigonometry ratios

So, we have

sin(75) = √2/2 * 1/2 + √2/2 * √3/2

So, we have

sin(75) = √2/4 + √6/4

Evaluate the sum

sin(75) = 1/4(√2 +√6)

Hence, the value is sin(75) = 1/4(√2 +√6)

Step-by-step explanation:

The explicit rule for the sequence -4/3, 1, -4/5, -2/3, -4/7 is -4(2 + n)

From the question, we have the following parameters that can be used in our computation:

-4/3, 1, -4/5, -2/3, -4/7

In the above sequence, we can see that 1 is added to the denomiator of the previous term to get the new term

Take for instance

2nd = -4/(3 + 1) = -1

3rd = -4/(3 + 2) = -4/5

4th = -4/(3 + 3) = -4/6 = -2/3

4th = -4/(3 + 7) = -4/7

Hence, the explicit rule is -4(2 + n)

Answer:

2.75

Step-by-step explanation:

To find the mean absolute deviation for a set of data, we first need to find the mean (average) of the data set. Then, for each data point, we find the absolute value of the difference between the data point and the mean. Finally, we take the mean of those absolute differences.

Step 1: Find the mean

Mean = (6+7+10+12+13+4+8+12)/8 = 72/8 = 9

Step 2: Find the absolute differences

|6-9| = 3

|7-9| = 2

|10-9| = 1

|12-9| = 3

|13-9| = 4

|4-9| = 5

|8-9| = 1

|12-9| = 3

Step 3: Find the mean of the absolute differences

Mean absolute deviation = (3+2+1+3+4+5+1+3)/8

Mean absolute deviation = 22/8

Mean absolute deviation = 2.75

Therefore, the mean absolute deviation for the given data set is 2.75.

To find out how many 1 1/2 foot boards can be cut from a 12 foot long board, we need to divide the length of the board by the length of each board.

First, we need to convert 1 1/2 feet to an improper fraction.

1 1/2 = (2 x 1 + 1) / 2 = 3/2

So, each board is 3/2 feet long.

Next, we divide the length of the 12 foot long board by the length of each board:

12 / (3/2) = 12 x 2/3 = 24/3 = 8

Therefore, 8 boards of length 1 1/2 feet can be cut from a 12 foot long board.

Based on the equation, we own 100 shares of JP Morgan Emerging Markets Bond Fund and 900 shares of Fidelity Conservative Income bond fund.

The portfolio is worth $10,000 in total:

$100x + $10y = $10,000

We can now use elimination to find x:

$1100x + $110y = $110,000 -($100x + $10y = $10,000)

$1000x = $100,000 x = 100

As a result, we own 100 shares of JP Morgan Emerging Markets Bond Fund. To solve for y, we can plug this number back into the original equation:

$100x + $10y = $10,000

$100(100) + $10y = $10,000

$10y = $9,000 y = 900

As a result, we have 900 shares of Fidelity Conservative Income bond fund

There is a financial advantage of $ 1,187,520.

Incremental Costs and Revenues will be as follows

Increment in sales = 82,000 units × 40% = 32,800 units

and, Selling Price

= (32,800 units × $62 per unit)

= $ 2,033,600

Direct materials

= $ 7.50 × 32,800 units

= 246,000

Direct labor

= $ 9.00 × 32800

= $295,200

and, Variable manufacturing overhead

As per the given percentage, the value of the loan 10 years after it starts is £4506.32.

We know the values of P and A for the first two years. So, we can use these values to find the value of r. Let's use the formula for the first year:

2645 = 2500(1 + r/1)¹ˣ¹

Simplifying the equation, we get:

1 + r = 2645/2500

1 + r = 1.058

r = 0.058 or 5.8%

Therefore, the interest rate per annum is 5.8% (to 1 decimal place).

Now, let's move on to finding the value of the loan after 10 years. We can use the same formula for compound interest, but we need to substitute the values of P, r, n, and t accordingly. Here's the formula:

A = P(1 + r/n)ⁿˣ

Where:

P = 2500

r = 0.058

n = 1 (as the interest is compounded annually)

x = 10

Substituting these values, we get:

A = 2500(1 + 0.058/1)¹ˣ¹⁰

A = 2500(1.058)¹⁰

A = 4506.32

Answer:

cm^3 can be used to represent volume.

The factor form of the given expression is [tex]x^2 - 14 - 4x = (x - 4)(x - 14).[/tex]

To factor the expression x^2 - 14 - 4x, we can use the technique of grouping.

First, we can rearrange the terms as:

x^2 - 4x - 14

Next, we can factor out a common factor of x from the first two terms:

x(x - 4) - 14

Then, we can factor out a negative 1 from the last two terms:

x(x - 4) - 1(14)

Finally, we can write the expression as the product of two binomials:

(x - 4)(x - 14)

Therefore, the factored form of x^2 - 14 - 4x is (x - 4)(x - 14).
