The triangle

On the triangle, we have the following ratio

x - 2 : 2 = x + 1 : 8

a) The vectors a and b are collinear when compa b=compb a. This means that they have the same direction, so that they're pointing in the same direction or opposite directions. In other words, if the angle between them is 0° or 180°, then they are collinear.

b) The vectors a and b are orthogonal when proja b=proj b a. This means that they are perpendicular to each other, so that the angle between them is 90°. Furthermore, it means that the projection of one vector onto the other is equal to zero.

This is because the projection of a vector onto itself is equal to the magnitude of the vector, while the projection of a vector onto a vector orthogonal to it is equal to zero.

A kilogram is a unit of mass in the metric system and is often used to measure the weight of food items. One kilogram is equivalent to 35.27 ounces. To determine how many ounces of peanut butter you used for your sandwich, you need to convert the mass in kilograms to ounces.

In this case, the jar contains 1.41 kg of peanut butter. To find the amount of peanut butter you used, you multiply the total amount by the percentage of the peanut butter you used. In this case, 8.0% of 1.41 kg is 0.11 kg of peanut butter.

Finally, you convert the 0.11 kg of peanut butter to ounces using the conversion factor of 35.27 ounces per kilogram. So 0.11 kg * 35.27 oz/kg = 3.88 ounces of peanut butter.

This answer is expressed to two significant figures because the original mass of the peanut butter is given to two significant figures (1.41 kg) and the percentage of peanut butter used is also given to two significant figures (8.0%).

the area of the given kite will be 60 feet².

What is area of Kite?

A polygon with four vertices and four sides enclosing four angles is called a quadrilateral. A unique quadrilateral known as the kite has successive sides that are all congruent, but the opposite sides are not. A rhombus is a kite that has four congruent sides. A kite's diagonals are perpendicular. The area of a kite is calculated as half of the diagonal product, which is the same as the area of a rhombus. The formula: can be used to express the area of a kite.

Area of Kite = 1/2*D1 * D2

D1 = long diagonal of kite

D2 = short diagonal of kite

The diagonals intersect each other so that the shorter diagonal is split into parts that are 2 feet and 2 feet and the longer diagonal is split into parts that are 10 feet and 20 feet.

So Area = 1/2 * 4 * 30 = 60 feet²

Answer:

Step-by-step explanation:

Given that sin θ = -4/9 and 3π/2 ≤ θ ≤ 2π, we can use the trigonometric identities to find cot θ.

cot θ = 1/tan θ = 1/ (sin θ / cos θ) = cos θ / sin θ

As we know the sin θ = -4/9, we can find cos θ = √(1 - sin^2 θ) = √(1 - (-4/9)^2) = √(1 - 16/81) = √(65/81)

So cot θ = (√(65/81)) / (-4/9) = -9/4 * √(65/81) = -(9/2) √(65/81)

Note that, since 3π/2 ≤ θ ≤ 2π, the value of cot θ will be negative

The parallel segments are MN & LK, MP & JK and NP & JL

The side lengths are listed below and the perimeter is 84 units

By definition, parallel segments are segments that extend indefinetely and do not meet

Using the above as a guide, we have the following:

The midsegments are given as

MP = 17, LK = 24 and PN = 13

This means that

JK = 2 * MP

JK = 2 * 17

JK = 34

Also, we have

MN = 1/2 * LK

MN = 1/2 * 24

MN = 12

Lastly, we have

JL = 2 * PN

JL = 2 * 13

JL = 26

For the perimeter, we have

Perimeter = JK + LK + JL

Perimeter = 34 + 24 + 26

Perimeter = 84

Hence, the perimeter is 84 units

An algebraic expression which is equivalent to the expression

csc[arccos(x -1)] is equal to 1 / √2x - x² .

Let us consider the expression arccos(x - 1 ) = y .

arccos(x - 1 ) = y

⇒ cos y = (x - 1 ) ___( 1 )

Now the required algebraic expression is equivalent to :

csc[arccos(x -1)]

= csc y

= ( 1 / sin y )

= 1 / √ 1 - cos²y   __(2)

Substitute the value of cosy from (1 ) in the expression ( 2 ) we get,

= 1 / √ 1 - ( x - 1 )²

= 1 / √ 1 -  ( x² -2x + 1 )

= 1 / √ 1 - x² + 2x - 1

The volume of a container is found to be 38.5 in³. Its volume in units of cm³ will be 630.902 cm³.

Unit conversion is a process with multiple steps involving multiplication or division by a numerical factor, particularly a conversion factor. The procedure may also demand the selection of the correct number of substantial digits and rounding. Different units of conversion are used to calculate different parameters.

We convert the units of any quantity to understand better. For example, the length of a table is measured in inches; on the other hand, the length of a garden is measured in yards to make it simple to comprehend. We cannot calculate the length of a finger in miles.

To create a formula to convert 38.49 in³ to cm³, we start with the fact that 1 inch is 2.54 centimetres, which means that you multiply inches by 2.54 to get centimetres. We can therefore make the following equation:

inches × 2.54 = centimeters

(inches × 2.54)³ = centimeters³

inches³ × 16.387064 = centimeters³

in³ × 16.387064 = cm³

Now that we have the in³ to cm³ formula, we can calculate and convert 38.5 in³ to cm³. Here is 38.5 in³ converted to cm³, along with the math and the formula:

= in³ × 16.387064

= 38.5 × 16.387064

The length of the rectangle is 23 km and the width of the rectangle is 15 km.

A rectangle is 8 km longer than it is wide.

Its area is 345 sq-km.

Let the width of the rectangle is x.

The length is 8 km longer than the width.

So the width of the rectangle is x + 8 km.

The formula of the area of rectangle is:

A = length × width

We know A = 345 sq-km.

Now putting the value

x × (x + 8) = 345

Now simplifying

x^2 + 8x = 345

Subtract 345 on both side, we get

x^2 + 8x - 345 = 0

Now factor the equation

x^2 + (23 - 15)x - 345 = 0

x^2 + 23x - 15x - 345 = 0

x(x + 23) - 15(x + 23) = 0

(x - 15)(x + 23) = 0

Now equation the factor equal to zero.

x - 15 = 0           or             x + 23 = 0

x = 15                or              x = -23

Since the dimension of the rectangle can't be negative. So

What is compound interest?

When interest is calculated, both the principal and the interest that has accumulated over the previous period are used. Compound interest accounts for the principal when calculating the interest for the subsequent month, as opposed to simple interest, which does not. In algebra, the letter C.I. is frequently used to denote compound interest.

We are given that after 16 years in an account with a 6.2% annual interest rate compounded continuously, an investment is worth a total of $58,226.31.

This means that

P(t) = $58,226.31

t = 16 years

r = 6.2%

We know that formula for continuous compounding interest is

[tex]P(t) = P_{0} e^{rt}[/tex]

So, using this, we get

⇒58,226.31 = Pe^(0.062*16)
