4. 17.32/20

5. 10/20

The lengths of PR and QS are; 20 and 28.28

The area of triangle PQR is, 282.8

The area of the rectangle PQRS is, 100√3.

The sine ratio of angle PRS is , 1 / 2.

The cosine ratio of angle PRQ is, √3 / 2.

The tangent ratio of angle PQS is, √3 / 3.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

we know that its diagonal bisects each other therefore PT=TR i.e. 10 units

PS = 20 units  

The area of triangle PQR = 1/2 x 28.28 x 20

= 282.8

Area of rectangle = PQ x PS

Area = 100√3

The angle PRS is 30°                                

The sum of interior angle of a triangle.

sin30° = PS/PR

1/2 x 20 = PS

PS= 10 units

The angle PRQ is 60°                                    

By Alternate interior angle

cosine60°=QR/PR

1/2 x 20 = QR

QR= 10 unit

cos QSR = 10/20

cosQSR=1/2

angle QSR = 60°

Thus angle PQS is 30°

tanPQS = 1/√3

PQ= 10√3

The length of RP is 5.66 unit. The Pythagorean theorem states that "In any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares  of the other two sides(the legs)".

Mathematically, the Pythagorean theorem can be represented as:

c^2 = a^2 + b^2;Where c represents the length of the hypotenuse and a and b represent the lengths of the other two sides (legs) of the right triangle.

Body of the Solution: Assuming RQ is the hypotenuse and RP and PQ are the legs.Since PQR is an isosceles triangle,then RP=PQ. we can apply the Pythagorean theorem to solve for the length of RP.

Let's represent the length of RP as x. According to the Pythagorean theorem,we have:

(RQ)^2 = (RP)^2 + (PQ)^2

Substituting the given value, we get:

8^2 = x^2 + x^2

64 = 2x^2

Dividing both sides by 2, we have:

32 = x^2

x = √32

Therefore, the length of RP is approximately 5.66 unit, rounded to two decimal places.

Thus, the length of RP is 5.66 unit.

Waterways should retain the old backhoes equipment.

To determine whether it is more favorable to purchase new backhoes or overhaul the old ones, we will evaluate the net present value (NPV), profitability index (PI), and internal rate of return (IRR) for both options.

Net Present Value (NPV):

For the new backhoes:

The initial cost of investment = Purchase cost when new - Salvage value now

= $199,994 - $15,200 = $184,794

The net cash flow generated each year for the new backhoes remains unspecified, so we cannot calculate its NPV.

For the old backhoes:

Initial investment = Cost of the overhaul = $41,400

Net cash flow generated each year = $15,200

Using the provided PV table, we can calculate the NPV for the old backhoes:

NPV = Net cash flow generated each year * PV factor for 8 years - Initial investment

= $15,200 * 5.76162 - $41,400 ≈ $55,689.69

Since the NPV for the old backhoes is positive, retaining the old equipment is favorable.

Profitability Index (PI):

The profitability index is calculated by dividing the present value of cash inflows by the initial investment.

For the new backhoes:

Since the net cash flow generated each year is unspecified, we cannot calculate the PI.

For the old backhoes:

PI = (Net cash flow generated each year * PV factor for 8 years) / Initial investment

= ($15,200 * 5.76162) / $41,400 ≈ 2.11

The profitability index for the old backhoes is 2.11.

Based on the PI, the old backhoes have a higher profitability index than the new backhoes, indicating that retaining the old equipment is more profitable.

Internal Rate of Return (IRR):

The IRR factor for the new and old backhoes is not provided, so we cannot calculate the exact IRR.

In summary, based on the net present value (NPV) and profitability index (PI), it is more favorable for Waterways to retain the old backhoes equipment.

Answer:

A=4.

Step-by-step explanation:

Note: In the expression of area the first term should be \(Ax^2\).

It is given that area of a rectangular floor of your house is \(Ax^2+5x-2\) and the length is \((x+2)\) units.

We know that, area of a rectangle is

\(Area=length\times width\)

Since length of the rectangle is \((x+2)\), therefore \((x+2)\) is a factor of \(Ax^2+5x-2\) and the value of \(Ax^2+5x-2\) is 0 at x=-2.

\(A(-2)^2+5(-2)-2=0\)

\(4A-10-2=0\)

\(4A-12=0\)

\(4A=12\)

Divide both sides by 4.

\(A=4\)

Therefore, the value of A is 4.

The radius of a circle having the equation x² + y² + 8x - 6y + 21 = 0 is 2  units .

In the question ,

it is given that ,

the circle is having the equation ⇒ x² + y² + 8x - 6y + 21 = 0 ,

we know that ,

general equation of circle is written as x² + y² + 2fx + 2gy + c = 0 ;

so , radius of circle is calculated using the below formula ,

radius = √(f² + g² - c)

On comparing,  given equation of circle with general equation of circle ,

we get , the values of f = 4 and g = -3 .

So after substituting the values of f , g and c in the radius formula ,

we get ,

radius = √(16 \(+\) 9 - 21)

= √(16 \(+\) 9 - 21)

= √(25 - 21) = √4 = 2 .

Therefore , the given circle has radius = 2 units .

The number of minutes that she practices in 5 weeks will be 980 minutes.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

Shandra rehearses the piano for 392 minutes in about fourteen days. Expecting she rehearses a similar sum consistently.

Let 'x' be the number of minutes that she practices in 5 weeks.

Then the number of minutes that she practices in 5 weeks will be given as,

x / 5 = 392 / 2

Simplify the equation, then we have

x / 5 = 392 / 2

x / 5 = 196

x = 980 minutes

The number of minutes that she practices in 5 weeks will be 980 minutes.

it would take the object approximately 11.51 seconds to reach the ground.

Generally, Time is a concept used to describe the progression of events, or the duration of those events. It is often measured in units such as seconds, minutes, hours, days, and years.

Time can also be described as a continuum, with past events on one end and future events on the other.

Time is a fundamental aspect of the universe and is closely related to concepts such as causation, change, and entropy.

The time it would take the object to reach the ground can be found by setting the distance from the ground, s, to 0 and solving for t.

A multiplier of 1.2 means the value is multiplied or increased by a factor of 1.2.

A multiplier is a term used to represent a factor by which a value is multiplied or increased. It is a numeric value that indicates the extent of the increase or expansion of a given quantity. Multiplication by a multiplier results in scaling or changing the magnitude of the original value.

A multiplier of 1.2 indicates that a value will be increased by 20% or multiplied by a factor of 1.2. This means that when the multiplier is applied to the original value, the resulting value will be 1.2 times the original.
