Answer:

42 square units

Step-by-step explanation:

Think of the polygon as being the rectangle GPST added to the triangle PES.

total area = area of rectangle GPST + area of triangle PSE

= LW + bh/2

= GT × GP + PS × h / 2

= 7(5) + 7(2)/2

= 35 + 7

= 42

Just a note of the height of the triangle. The height of triangle PSE, h, is the segment with endpoints E and point (2, 2), so its length is 2.

The required volume of the wallet in m3 is 0.001393030684 m3.

Given, The volume of a wallet is 8.50 in. 3.

Convert this value to m3, using the definition 1 in. = 2.54 cm.

The given value of volume is 8.50 in.3.

But we need to convert it into m3.

We have, 1 in. = 2.54 cm.

Hence, 1 in.3 = (2.54 cm)3

                      = (2.54 × 2.54 × 2.54) cm3

                      = 16.387064 cm3

In order to convert the value from cm3 to m3, we need to follow the given steps:1

m = 100 cm

⇒ (1 m)3 = (100 cm)3

               = 106 cm3

Now, we have the relation, 16.387064 cm3 = 1 in.3

⇒ 1 cm3 = (1/16.387064) in.3

∴ 8.50 in.3 = 8.50 × 16.387064 cm3

                  = 139.3030684 cm3

∵ 1 m3 = (1/106) cm3

∴ 139.3030684 cm3= (139.3030684 × 10−6) m3

∴ 8.50 in.3= 1.393030684 × 10−3 m3

                 = 0.001393030684 m3

Hence, the required volume of the wallet in m3 is 0.001393030684 m3.

Answer: The width of the model = 11.33 inches and the height of the model = 20.27 inches.

Step-by-step explanation:

Given: Scale factor:  2 inches in model =  15 feet in actual.

White house is about 85 feet wide and 152 feet long.

Width of model = \(\dfrac2{15}\times85=\dfrac{34}{3}=11.33\text{ inches}\)

Height of model = \(\dfrac{2}{15}\times152\approx20.27\text{ inches}\)

Hence, the width of the model = 11.33 inches and the height of the model = 20.27 inches.

a) To make the table for the proportional relationship, given that he delivers 14 newspapers in 20 minutes, the first step is to determine the unit rate (or constant of proportionality), that is, the number of papers he delivers in one minute.

Let x be the time in minutes and y be the number of newspapers delivered, their relationship can be expressed as:

Where k is the constant of proportionality, you can calculate it as:

For x=20 and y=14

The unit rate is 0.7 newspapers per minute.

(i) At t = 0.5 s, the voltage output is approximately 0.1737 volts, and the indicated pressure is approximately 129.18 psi.

(ii) The output reaches 5.0 volts approximately at t = 0.6764 s.

(i) At t = 0.5 s, we need to calculate the voltage output and the indicated pressure.

To find the voltage output, we first need to determine the resistance at t = 0.5 s using the given pressure-resistance relationship. Substituting p = 150 psi into the equation R = (0.15p km) p + 2.5 kΩ, we get R = (0.15 * 150) + 2.5 = 25 + 2.5 = 27.5 kΩ.

Next, we can calculate the voltage output using the voltage-resistance relationship. Substituting R = 27.5 kΩ into V = (0.15p em) R / (R + 10 kΩ), we get V = (0.15 * 150 * e^-27.5) * 27.5 / (27.5 + 10) = 0.1737 volts.

To determine the indicated pressure, we can rearrange the voltage-resistance relationship and solve for p. Substituting V = 0.1737 volts and R = 27.5 kΩ, we get p = -ln[(40 * R * V) / (R + 10 kΩ)] / (0.15 * e^-R) = 129.18 psi.

Therefore, at t = 0.5 s, the voltage output is approximately 0.1737 volts, and the indicated pressure is approximately 129.18 psi.

(ii) To find the time at which the output reaches 5.0 volts, we need to determine the time constant and the corresponding time value.

Given that the sensor time constant is 350 ms, we know that the voltage will reach approximately 63.2% of its final value after one time constant. Therefore, the voltage at the time constant (t = τ) is V(τ) = 0.632 * 5.0 volts = 3.16 volts.

To find the time at which the voltage reaches 3.16 volts, we can solve for t in the voltage equation V = (0.15p em) R / (R + 10 kΩ). Rearranging the equation and substituting V = 3.16 volts, we get t = -ln[(R * V) / (40 * R - V * R - 10 kΩ)] / (0.15 * e^-R).

Calculating the value of R using the given pressure-resistance relationship for p = 150 psi, we get R = 27.5 kΩ. Substituting this value into the equation, we find t ≈ 0.6764 s.

Therefore, the output reaches 5.0 volts approximately at t = 0.6764 s.

Answer:

Strictly speaking, there is not enough information to solve the problem.

If we assume m<EFY = 90, then:

m<DEY = 29

m<DEF = 58

Step-by-step explanation:

Going by the exact information shown, the answer is really that there isn't enough information to answer the question.

On the other hand, if angle EFY is a right angle, then we have two right triangles that can be proved congruent by HL. Then by CPCTC, angles DEY and FEY are congruent. We set their measures equal and solve for y.

4y - 7 = 2y + 11

2y = 18

y = 9

m<DEY = 4y - 7 = 4(9) - 7 = 36 - 7 = 29

m<DEF = 2m<DEY = 2(29) = 58

The parametric equations for the ellipse x^2/2^2 + y^2/4^2 = 1, traced clockwise as the parameter increases, are:
x = 2cos(t)
y = -2sin(t)

To find the corresponding y-value for a given x-value on the ellipse, we can rearrange the equation:

x^2/2^2 + y^2/4^2 = 1
y^2/4^2 = 1 - x^2/2^2
y^2 = 4^2(1 - x^2/2^2)
y = ±2sqrt(1 - x^2/2^2)

Since the curve is traced clockwise as the parameter t increases, we can set x = 2cos(t) and y = -2sqrt(1 - x^2/2^2) to trace the lower half of the ellipse:

x = 2cos(t)
y = -2sqrt(1 - (2cos(t))^2/2^2)
y = -2sqrt(1 - cos^2(t))

Using the identity sin^2(t) + cos^2(t) = 1, we can solve for sin(t):

sin^2(t) = 1 - cos^2(t)
sin(t) = ±sqrt(1 - cos^2(t))

Since we want the negative value to trace the lower half of the ellipse, we have:
y = -2sin(t)

Therefore, the parametric equations for the ellipse x^2/2^2 + y^2/4^2 = 1, traced clockwise as the parameter increases, are:
x = 2cos(t)
y = -2sin(t)

The profit-maximizing price and quantity for the monopolist are $350 and 150 units, respectively ,The expected return is greater than the initial investment And the producer surplus is $33,750, consumer surplus is $31,875, and firm profit is $37,500.

Ignoring the time value of money and discounting, the expected value of the lottery winnings each year is 2% × $1 million = $20,000, and this goes on for 10 years.

Thus, the expected value of the investment is 10 × $20,000 = $200,000.

Hence, the expected return is greater than the initial investment, and there is a condition under which the investment can be made.

The monopolist’s total cost can be represented as:

TC = 300 + 200Q + 3Q².

The demand function for the monopolist is given as:

Q = 500 - P,

which can be rearranged to derive the price function as:

P = 500 - Q.

From the total cost function, we can obtain the marginal cost (MC) as the derivative of TC with respect to Q, and it can be represented as follows:

MC = dTC/dQ = 200 + 6Q.

From the marginal cost, we can set the marginal revenue (MR) equal to MC to get the profit-maximising quantity as follows:

MR = dTR/dQ = P + Q(500 - P) = 500 - Q + 500Q - Q² = 1000Q - Q² - 500 = MC = 200 + 6Q.

Substituting P = 500 - Q in the above expression and rearranging yields the following:

Q = 150, and hence, P = $350.

Therefore, the profit-maximising price is $350, and the quantity is 150. We can verify that the solution is a maximum by computing the second-order condition, which is negative.

To calculate the producer surplus, we first need to obtain the area above the marginal cost and below the price.

Thus, we have:

PS = ∫ MC to QdQ

= ∫ (200 + 6Q) dQ from 0 to 150

= [200Q + 3Q²] from 0 to 150

= $33,750.

Similarly, the consumer surplus can be computed as the difference between the market value of the product and what the consumers paid for it. The area below the price line and above the demand curve yields the consumer surplus.

Thus, we have:

CS = ∫ P to QdQ

= ∫ (500 - Q) dQ from 0 to 150

= [(500 × Q) - (Q²/2)] from 0 to 150

= $31,875.

Finally, the firm profit can be obtained by multiplying the profit-maximizing quantity by the profit-maximizing price and subtracting the total cost.

Thus, we have:

Profit = TR - TC = Q × P - TC = (150 × $350) - (300 + 200 × 150 + 3 × 150²) = $37,500.

Hence, the producer surplus, consumer surplus, and firm profit are $33,750, $31,875, and $37,500, respectively.

The area of the third side of the triangle is either 20 square unit or 12 square units.

Triangle:

in math, triangle refers a simple closed curve made of three line segments and it has three vertices, three sides and three angles.

Given,

Two sides of a right triangle measure 2 units and 4  units.

And we need to find the area of the square that shares a side with the third side of the triangle  ​

Let us consider is  Two sides of a right triangle measure 2 units and 4  units.

Here if sides are perpendicular sides, then by using Pythagorean theorem

=> third side² = 2² + 4²

When we simplify this one, then we get,

=> third side² = 4 + 16

So, the  third side² = 20

Then the area of the square that shares a side with the third side of the triangle =  third side² = 20 sq units

Similarly, if 4  units is hypotenuse side, then by using Pythagorean theorem, the third side is calculated as,

=> third side² = 4² - 2²

And when we simplify this one, then we get,

=> third side² = 16 - 4

Therefore, the third side² = 12

And the area of the square that shares a side with the third side of the triangle =  third side² = 12 sq units
