the equation that can be used to express the area of the window in terms of its width is: Area = AB * [(8-2AB)/π] + 1/2 [(8-2AB)/π]^2

Given:

The perimeter of the window is 8 m.

Shape of window: Rectangle topped by a semicircle

Let AB be the width and BC be the radius of semicircle.

Since the perimeter of the window is given as 8m,

Therefore, AB + BC + AB = 8mAB + AB + (1/2)(2πr) = 8mAB + AB + πr = 8mπr = 8m - 2ABπr = (8-2AB)/π

Now, the area of the window can be expressed as,

Area of rectangle + Area of semicircleArea = AB * BC + 1/2 (πr^2)Area = AB * r + 1/2 (πr^2)

Putting the value of r in terms of AB,

Area = AB * [(8-2AB)/π] + 1/2 [(8-2AB)/π]^2

Hence, the equation that can be used to express the area of the window in terms of its width is:

Area = AB * [(8-2AB)/π] + 1/2 [(8-2AB)/π]^2

Based on the information, the quadrilateral can be classified as a square.

A quadrilateral is a term that refers to the set of geometric figures that has four sides. There are several types of quadrilaterals depending on the length of their sides and the angles of their edges, for example rectangles have four sides, but two of them are longer (the base and the upper side), others like the parallelogram have two sides of a greater length (base and upper side and the angles of any two adjacent vertices are supplementary (add to 180°).

In this case, the quadrilateral has all its sides equal and all its angles are 90°. From the above, we can infer that this is a square.

The period of time between treatments in which no treatment is given so that the effects of a previous treatment are eliminated before introducing a new treatment is called a washout period.

The period of time between treatments in which no treatment is given so that the effects of a previous treatment are eliminated before introducing a new treatment is called a washout period.

This period allows the body to return to its baseline state before starting a new treatment. The duration of the washout period depends on the specific treatment and its effects on the body.

The washout period allows for the evaluation of the effects of the new treatment without interference from the previous medication or treatment. The goal of a washout period is to reduce the potential for confounding variables that could impact the accuracy and reliability of the study results.

The area of the shaded region is 7π square centimeters.

Step-by-step explanation:

Note that Circle B has a radius of 3 cm, and the two smaller circles, Circles O and C, both have a radius of 1 cm.

The area of a circle is given by:

\(\displaystyle A = \pi r^2\)

Therefore, the area of Circle B, the entire circle, is:

\(\displaystyle \begin{aligned} A_B &= \pi (3)^2 \\ &= 9\pi \end{aligned}\)

The area of Circle O is:

\(\displaystyle \begin{aligned} A_O &= \pi (1)^2 \\ &= \pi \end{aligned}\)

And likewise, the area of Circle C is:

\(\displaystyle \begin{aligned} A_C &= \pi (1)^2 \\ &= \pi \end{aligned}\)

The area of the shaded area is the area of the Circle B subtracted by the area of Circles O and C. Hence:

\(\displaystyle A_\text{shaded} =A_B - \left(A_ O + A_ C\right)\)

Substitute and evaluate:

\(\displaystyle \begin{aligned} A_\text{shaded} &= (9\pi ) - (\pi + \pi) \\ &= 9\pi - 2\pi \\\ &= 7\pi \end{aligned}\)

The area of the shaded region is 7π square centimeters.

Let largest value of data be L

and smallest value of data be S.

We are given that the range and coefficient of range of the data are 17 and 0.2 respectively.

Range formula is given by = Largest value - Smallest value

                   17  =   L - S

                  L = 17 + S ---------- [Equation 1]

Coefficient of range formula = (Largest - Smallest) ÷ (Largest + Smallest)

                                       0.2   =    l-s/l+s

                                      0.2 = 17/l+s

                 L + S = 17/0.2 = 85

So,    L + S = 85

       17 + S + S = 85   {using equation 1}

           2*S = 80

             S = 80/2 = 40

Putting value of S in equation 1, we get L = 20 + 40 = 60

Therefore,  Largest value, L = 60

               smallest value, S = 40

By using the statements AE = EB, ∠CAB = ∠CBA, and mCB = mCAB, we can prove that triangle ABC is isosceles. The following statements can be used to prove that triangle ABC is isosceles:

AE = EB

∠CAB = ∠CBA

mCB = mCAB

To prove that AE = EB, we can use the fact that an altitude of a triangle bisects the base. This means that AD divides BC into two segments of equal length, BD and CD. Since AE and EB are the projections of AD onto AB and AC respectively, they must also be equal in length.

To prove that ∠CAB = ∠CBA, we can use the fact that the angles opposite equal sides of a triangle are equal. Since AE = EB, we know that ∆AED and ∆CEB are congruent by SSS. This means that ∠AED = ∠CEB, and since ∠AED + ∠CEB = ∠CAB + ∠CBA, we have ∠CAB = ∠CBA.

To prove that mCB = mCAB, we can use the fact that the base angles of an isosceles triangle are equal. Since ∠CAB = ∠CBA, we know that ∆ABC is isosceles, and therefore mCB = mCAB.

Let's denote the radius of the cone as 'r' and the height as 'h'.

The formula for the volume of a cone is:

V = (1/3) * π * r^2 * h

And the formula for the circumference of the base of a cone is:

C = 2 * π * r

We know that the volume of the cone is 33π/3, so:

(1/3) * π * r^2 * h = 33π/3

Simplifying this equation, we get:

π * r^2 * h = 99π

r^2 * h = 99

We also know that the circumference of the base of the cone is 6π, so:

2 * π * r = 6π

Simplifying this equation, we get:

r = 3

Now we can substitute this value of 'r' into the equation we obtained earlier:

r^2 * h = 99

3^2 * h = 99

h = 11

Therefore, the height of the cone is 11 units.

If one exterior angle of a regular polygon measures 72°, the measure of one interior angle can be determined using the relationship between exterior and interior angles in a polygon.

In a regular polygon, all exterior angles are congruent, meaning they have the same measure. The sum of the measures of the exterior angles of any polygon is always 360°. Therefore, if one exterior angle measures 72°, the polygon must have 360° divided by 72°, which is 5 sides or vertices.

To find the measure of one interior angle of a regular polygon, we can use the formula:

Interior angle = 180° - Exterior angle

Since we know the exterior angle measures 72°, we can substitute it into the formula:

Interior angle = 180° - 72°

Interior angle = 108°

Therefore, the measure of one interior angle in this regular polygon is 108°.

Answer:

The average speed on the return trip is 2.44 miles/h.                  

Step-by-step explanation:

To find the average speed we need to use the following equation:

\( \overline{v} = \frac{d}{t} \)

Where:

d: is the distance

t: is the time

Since the question is to find the average speed on the return trip, we will take the data of the time and speed of only the return trip.

\(\overline{v} = \frac{d}{t} = \frac{5 + 1/2}{2 + 1/4} = 2.44 miles/h\)                

Therefore, the average speed on the return trip is 2.44 miles/h.

Answer:

Step-by-step explanation:

5t-8 and 68 are the angles of a straight line so their addition will be180°.

5t-8 + 68 = 180

5t + 60 = 180

5t = 180-60

Answer:

Part A:  x= 0.02 (rounded)

divide by 62

Part B:  x= 0.02 (rounded)

divide by 60

The answer would be

A = $8,650

P = $5,000

t = 5 years

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the amount of money after t years

P = the principal (initial deposit)

r = the annual interest rate

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

t = the number of years

We know that Allen opened a retirement savings account with an initial deposit of $5,000 and made annual contributions. After 5 years, the account grew to $8,650. We don't know the annual interest rate or how the interest is compounded, so we can use the formula to find out.

Let's assume that Allen made no additional contributions to the account after the initial deposit. Then:

A = $8,650

P = $5,000

t = 5 years

We can rearrange the formula to solve for r:

The volume of inhaled air at a maximum at t = 2, 4, 6, ...

The volume of inhaled air is at a maximum when the function V(t) is at a maximum. This occurs when the derivative of V(t) is equal to zero.

The derivative of V(t) is:

V'(t) = (3/5) pi * (pi/2) * sin(pi t/2)

Setting this equal to zero gives:

(pi/2) * sin(pi t/2) = 0

This occurs when pi t/2 is equal to a multiple of pi. This means that t/2 is equal to a multiple of 1, or t is equal to a multiple of 2. Therefore, the volume of inhaled air is at a maximum when t = 2, 4, 6, ...
