Which of the following values are in the range of the function graphed below?
Check all that apply.

Answer:

Yes, the students' reasoning is correct. The percent of a part compared to the whole is calculated by dividing the part by the whole and multiplying the result by 100. Since the part is much less than the whole, the result of the division will be a very small number, and when multiplied by 100, it will be an even smaller number, which is the percentage.

Step-by-step explanation:

1. Divide the part by the whole to calculate the fraction that the part is of the whole.

2. Multiply the result by 100 to convert the fraction to a percentage.

3. Since the part is much less than the whole, the result of the division will be a very small number, and when multiplied by 100, it will be an even smaller number, which is the percentage.

Step-by-step explanation:

The expectation value of the position squared when the particle in the box is in its third excited state is equal to \(\frac{9l^2}{8}\), where l is the length of the box. This is equal to nine-eighths of the length of the box squared.

The expectation value of the position squared when the particle in the box is in its third excited state can be calculated using the formula\(\langle x^2 \rangle = \frac{l^2}{8} \left( 2n^2 + 6n + 3 \right)\),

where n is the quantum number of the state and l is the length of the box. Here, n is 3, so the expectation value is equal to

\(\frac{l^2}{8} \left( 2 \times 3^2 + 6 \times 3 + 3 \right) = \frac{9l^2}{8}\).

This can be written as nine-eighths of the length of the box squared.

Given:

Point C divides AB such that AC:BC=2:3.

To find:

The x-value for point C.

Solution:

Section formula: If a point divide a line segment in m:n, then

\(Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)\)

Form the given graph it is clear that the endpoints of the line segment AB are A(-3,5) and B(3,0).

Point C divides AB such that AC:BC=2:3. Using section formula, the coordinates of point C are

\(C=\left(\dfrac{2(3)+3(-3)}{2+3},\dfrac{2(0)+3(5)}{2+3}\right)\)

\(C=\left(\dfrac{6-9}{5},\dfrac{0+15}{5}\right)\)

\(C=\left(\dfrac{-3}{5},\dfrac{15}{5}\right)\)

\(C=\left(-0.6,3\right)\)

The x-value of C is -0.6.

Step-by-step explanation:

The speedup is 1, which means that the multi-processor system with 50 processors does not provide any speedup compared to the single-processor system.

In the single-processor system, the workload is done by a single processor. In the multi-processor system with 50 processors, one processor handles 20% of the workload, and the remaining 49 processors share the remaining 80% of the workload.

To calculate the speedup, we need to compare the time taken by the single-processor system with the time taken by the multi-processor system.

Let's assume that the time taken by the single processor to complete the workload is T_single.

In the multi-processor system, the time taken by the one processor to complete its 20% workload is 0.2 * T_single.

The remaining 80% of the workload is distributed among the other 49 processors. Each processor will handle (80% / 49) of the workload, which is approximately 1.6327% of the total workload.

Since the workload is embarrassingly parallel, each processor can work independently on its portion of the workload.

The total time taken by the multi-processor system is T_multi = 0.2 * T_single + 49 * (0.016327 * T_single) = 0.2 * T_single + 0.8 * T_single = T_single.

Therefore, the speedup of the multi-processor system compared to the single-processor system is:

Speedup = T_single / T_multi = T_single / T_single = 1

The answers, rounded to the appropriate number of significant figures, are as follows:

(a) 1.088 ×\(10^2\)

(b) 2.132

(c) 1.3331 ×\(10^1\) and

(d) 1.05.

Let's calculate the answers to the given operations using the appropriate number of significant figures.

(a) 8.370×1.3×10

To perform this multiplication, we multiply the decimal numbers and add the exponents of 10:

8.370 × 1.3 × 10 = 10.881 × 10 = 1.0881 × \(10^2\)

Since the original numbers have four significant figures, we round the final answer to four significant figures:

1.088 × \(10^2\)

(b) 4.265/2.0

For division, we divide the decimal numbers:

4.265 ÷ 2.0 = 2.1325

Since both numbers have four significant figures, the answer should be rounded to four significant figures:

2.132

(c) (1.2588×\(10^3\))×(1.06×\(10^-^2\))

To multiply these numbers, we multiply the decimal numbers and add the exponents:

(1.2588 × \(10^3\)) × (1.06 × \(10^-^2\)) = 1.333128 × \(10^1\)

Since the original numbers have five significant figures, we round the final answer to five significant figures:

1.3331 × \(10^1\)

(d) \((1.11)^(^1^/^2^)\)

To calculate the square root, we raise the number to the power of 1/2:

\((1.11)^(^1^/^2^)\)= 1.0524

Since the original number has three significant figures, the answer should be rounded to three significant figures:

1.05

It's important to note that the significant figures in a result are determined by the original data and the operations performed. The final answers provided above reflect the appropriate number of significant figures based on the given information and the rules for significant figures.

The graph illustrates the supply and demand curves on a single graph to represent the equilibrium point in a market. The equilibrium point is where the quantity demanded equals the quantity supplied, resulting in a balance between buyers and sellers.

This point determines the market price and quantity exchanged in the market. The graph demonstrates the interplay between supply and demand, showcasing how changes in these factors can impact the equilibrium point and market outcomes.

The equilibrium point is the intersection of the supply and demand curves on the graph. At this point, the quantity demanded by buyers matches the quantity supplied by sellers. The equilibrium price is determined by the vertical position of the equilibrium point on the graph, while the equilibrium quantity is determined by the horizontal position.

If the market price is above the equilibrium price, there is excess supply, leading to a surplus. Sellers will be motivated to decrease prices to sell their goods, which, in turn, increases the quantity demanded. Conversely, if the market price is below the equilibrium price, there is excess demand, resulting in a shortage. Buyers will be incentivized to bid higher prices, increasing the quantity supplied by sellers.

The equilibrium point represents a state of market balance where the forces of supply and demand are in harmony. It reflects the price and quantity at which both buyers and sellers are satisfied, maximizing the efficiency of resource allocation in the market.

The maximum possible draft is 6.85 mm (rounded to the nearest hundredth).

The maximum possible draft is 6.85 mm (rounded to the nearest hundredth).

The given parameters for the flat rolling are:

Width of the strip (w) = 300 mm

Thickness of the strip before rolling (t₁) = 30 mm

Thickness of the strip after rolling (t₂) = 23.5 mm

Radius of the rolls (R) = 241 mm

Roll speed (N) = 50 rev/min

Coefficient of friction between rolls and work (μ) = 0.10

The flow curve of the material can be described using the following formula:

σ = Kεⁿ,

where

σ = Flow stress

K = Strength coefficient

ε = Strainn = Strain-hardening exponent

Since the material is assumed to have a flow curve defined by:

K = 275 MPa and

n = 0.15,

the formula can be rewritten as:

σ = 275ε^0.15

This equation will be used to calculate the rolling force.

First, the mean flow stress should be calculated.

This can be done using the following formula:

σ_avg = (1 / ε)∫[σ(ε)dε],

where

ε = (t₁ - t₂) / t₁

= (30 - 23.5) / 30

= 0.2167

σ = 275ε^0.15

Then,σ_avg = (1 / 0.2167)∫[275(ε^0.15)dε]

= 374.4 MPa

The maximum possible draft can be calculated using the following formula:

Maximum possible draft = (πR/2N)[(σ_avg/μ)ln(t₁/t₂)],

where, R

= 241 mm N

= 50 rev/minσ_avg

= 374.4 MPaμ

= 0.10t₁

= 30 mmt₂

= 23.5 mm

Maximum possible draft = (π × 241 / 2 × 50)[(374.4 / 0.10)ln(30 / 23.5)]

Maximum possible draft = 6.85 mm (rounded to the nearest hundredth)

The time it takes the ball to strike the ground after it is thrown, found using the kinematic equation, H = -16·t² - 24·t + 200 is approximately 2.86 seconds

A kinematic equation is an equation of the motion of an object moving with a constant acceleration.

The direction in which the ball is thrown = Downwards

Height of the building = 200 foot

Initial velocity of the ball = 24 ft./s

The kinematic equation that indicates the height of the ball after t seconds is, H = -16·t² - 24·t + 200

At ground level, H = 0, therefore;

H = 0 = -16·t² - 24·t + 200

-16·t² - 24·t + 200 = 0

-2·t² - 3·t + 25 = 0

t = (3 ± √((-3)² - 4 × (-2)×25))/(2×(-2))

t = (3 ± √(209))/(-4)

Step-by-step explanation:

Exponential Function

General form of an exponential function:

  \(y=ab^x\)

where:

If b > 1 then it is an increasing function

If 0 < b < 1 then it is a decreasing function

If the rate of decrease is 4% per year, that means that each year the number of fish is 96% of the previous year, since 100% - 4% = 96%

Given:

Substitute the given values into the exponential equation:

\(\implies y=1150(0.96)^t\)

If the initial year was 2004 then:

⇒ t = 2009 - 2004 = 5

Substitute t = 5 into the equation and solve for y:

\(\implies y=1150(0.96)^5\)

\(\implies y=937.6786022...\)

Therefore, the population in 2009 was 938 (to the nearest whole number).
