Answer:

3 pizzas

Step-by-step explanation:

34-4=30

30/10=3

Answer:

3 pizzas

Step-by-step explanation:

34-4=30 since we already know the delivery fee

30/10=3 since we have 30 dollars left without the delivery fee we are just left to divide 30 by 10 to get the total number of pizzas

v = 1/e ax [sin^-1 (u) + c]Substituting back for u = v/1, we have:v = 1/e ax [sin^-1 (v) + c]This is the required solution.

(a) To determine a function in Eq. (1) for which K = 1, the following steps will be taken:Given that K = y''/[1 + (y')²]3/2 ............(1)Differentiating (1) with respect to x yields:dK/dx = [(1 + (y')²)3/2 y''' - 3y' y'' (y')²]/(1 + (y')²)3 ......(2)Substituting K = 1 in (1) yields:1 = y''/[1 + (y')²]3/2or y'' = [1 + (y')²]3/2 ...................(3) Integrating (3) once gives:y' = sin c1√(1 + y²) ...........(4)Where c1 is the constant of integration. Squaring (4), we obtain:y'² = sin² c1 (1 + y²)...............(5)Differentiating (5) with respect to x yields:y'' = d/dx[sin² c1 (1 + y²)]/2√(1 + y²) ..........(6)On substituting (5) in (6), we have:y'' = sin c1(cos² c1)/(1 + y²)3/2  ............(7)Now, equating (1) and (7), we have:sin c1(cos² c1)/(1 + y²)3/2 = 1/(1 + y²)3/2 ...........

.(8)Therefore, sin c1 cos² c1 = 1 ...............(9)But cos² c1 = 1 - sin² c1.Substituting this in (9), we have: sin c1(1 - sin² c1) = 1 ............(10)Multiplying throughout by (1 + sin² c1), we get: sin c1 + sin³ c1 = 1 + sin² c1 .............(11)Rearranging, we obtain: sin³ c1 + sin² c1 - sin c1 - 1 = 0 ............(12)This cubic equation in sin c1 has one root at sin c1 = 1. Hence, we take sin c1 = 1.Substituting this value of sin c1 in (4), we have:y' = √(2)y ..........(13)Integrating (13) with respect to x, we obtain:y = k ex/√(2) ..........(14)Where k is the constant of integration. Therefore, the required function in Eq. (1) for which K = 1 is given by:y = k ex/√(2).(b) Given the differential equation:dy/dx + a sin y = cos yWe use the substitution v = sin y. Therefore, we have:dv/dx = cos y dy/dx = cos y(1 - v²) ..........(15)Substituting (15) in the differential equation, we obtain:dv/dx + a v = cos y = √(1 - v²)

Now, this is a first-order linear differential equation that can be solved using an integrating factor of e ∫adx = e ax. Multiplying both sides of the equation by e ax, we obtain:e ax dv/dx + ae ax v = e ax √(1 - v²)Differentiating both sides with respect to x, we obtain:(d/dx)[e ax v] = e ax √(1 - v²)Multiplying throughout by dx and integrating both sides, we get:e ax v = sin^-1 (u) + cWhere u = v/1, and c is the constant of integration. Therefore,v = 1/e ax [sin^-1 (u) + c]Substituting back for u = v/1, we have:v = 1/e ax [sin^-1 (v) + c]This is the required solution.

Answer:8

Step-by-step explanation:

The area of the walkway is 24π square meters.

To find the area of the walkway, we need to subtract the area of the inner circle from the area of the outer circle.

The inner circle has a radius of 5 meters, so its area can be calculated using the formula for the area of a circle: A_inner = π * \((r_inner)^{2}\).

A_inner = π * \(5^{2}\) = 25π square meters.

The outer circle has a radius equal to the sum of the inner radius and the width of the walkway. In this case, the outer radius is 5 + 2 = 7 meters.

The area of the outer circle can be calculated in the same way: A_outer = π * \((r_outer)^{2}\).

A_outer = π * \(7^{2}\) = 49π square meters.

Now, we can find the area of the walkway by subtracting the area of the inner circle from the area of the outer circle: A_walkway = A_outer - A_inner.

A_walkway = 49π - 25π = 24π square meters.

The area of the walkway is 24π square meters, where π (pi) is a mathematical constant approximately equal to 3.14159.

Answer:

125 degrees

Step-by-step explanation:

If I am reading the drawing correctly you have angles in matching corners.  These are called Corresponding Angles and are equal to each other.  So we know that the angle labelled (2x - 115) is equal to 135.  So we set that up and solve for x

2x - 115 = 135

2x = 250

x = 125

Answer:

8b

Step-by-step explanation:

You can factor the b-term out since b-term exists for all terms in the expression. By factoring out, you are basically dividing the factored term off and put it outside of the bracket, thus:

\(\displaystyle{16b-8b=\left(16-8\right)b}\)

Then evaluate and simplify:

\(\displaystyle{\left(16-8\right)b=8\cdot b}\\\\\displaystyle{=8b}\)

The magnitude of the net magnetic field at the square's center is \(= (7.94 * 10^{-4}N/m)i+(-7.94 * 10^{-4}N/m)j\).

Using \(dB=\frac{u_0i}{4\pi} \frac{sin\theta}{r^2}\) the force on say, wire 1 (the wire at the upper left of the figure) is along the diagonal (pointing toward wire 3, which is at the lower right). Only the forces (or their components) along the diagonal direction contribute. With θ=45°, we find the force per unit meter on wire 1 to be

\(f_1 = |F_{12}+F_{13}+F_{14}|\\\\= 2F_{12}cos\theta+f_{13}\\\\=2(\frac{u_0i^2}{2\pi a} )cos45^0+\frac{u_0i^2}{2\sqrt{2}\pi a }\)

\(=\frac{3}{2\sqrt{2}\pi }(\frac{u_0i^2}{0})\\\\=\frac{3}{2\sqrt{2}\pi } \frac{(4\pi*10^{-7}T.m/A)(15.0A)^2} {(8.50*10^{-2}m)}\)

\(= 1.12 * 10^{-3}N/m\)

The direction of F1​ ​ is along r^=(i^=j^​)/sqrt2. In unit-vector notation, we have

\(F_1 = \frac{(1.12 * 10^{-3}N/m)}{\sqrt{2} }(i - j) \\\\= (7.94 * 10^{-4}N/m)i+(-7.94 * 10^{-4}N/m)j\)

Hence the answer is the magnitude of the net magnetic field at the square's center is \(= (7.94 * 10^{-4}N/m)i+(-7.94 * 10^{-4}N/m)j\).

Answer:

The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)

Step-by-step explanation:

If the point (x, y) dilated by a scale factor k using the origin as a center of dilation, then its image is (kx, ky)

Let us use this rule to solve our question

∵ The vertices of ΔDEF are D (8, 4), E (2, 6), and F (3, 1)

∵ ΔDEF dilated by a scale factor 5

∴ k = 5

∵ The origin as the center of dilation

→ That means, multiply the coordinates of every point by 5

∴ D' = (8 × 5, 4 × 5)

∴ D' = (40, 20)

∴ E' = (2 × 5, 6 × 5)

∴ E' = (10, 30)

∴ F' = (3 × 5, 1 × 5)

∴ D' = (15, 5)

∴ The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)

Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

Answer:

$8

Step-by-step explanation:

Using the information we already know, we can form an equation:

Let x be the socks' original price.

\((24+x)\) × \(0.75=24\)

Divide both sides by 0.75

\(24+x=32\)

Subtract 24 from both sides

\(x=8\)

The socks' original price was $8.

Answer:

4

Step-by-step explanation:

To solve for x in the equation:

√(2x - 7) = 1

We can start by isolating the square root by squaring both sides of the equation:

(√(2x - 7))^2 = 1^2

2x - 7 = 1

Next, we can isolate the variable by adding 7 to both sides of the equation:

2x = 8

Finally, we can solve for x by dividing both sides by 2:

x = 4

Therefore, the solution to the equation √(2x - 7) = 1 is x = 4.

It appears that a Type II error was made in the hypothesis test conducted by the user.

A Type II error, also known as a "false negative," is a statistical error that occurs when a null hypothesis is actually true, but a hypothesis test fails to reject the null hypothesis, leading to the incorrect conclusion that there is no significant effect or difference when, in fact, there is.

According to the given information:

Based on the given information, it appears that a Type II error was made in the hypothesis test conducted by the user.

In this case, the user claimed that the mean number of shades the toothpaste whitens teeth is less than four, and conducted a hypothesis test to test this claim. However, the given information states that the true mean number of shades the toothpaste whitens teeth is actually four. If the user failed to reject the null hypothesis, it means that they did not find enough evidence to support their claim that the mean number of shades is less than four, even though it is actually true.

This would be a Type II error because the null hypothesis (which assumes that the mean number of shades is four) is actually true, but the test failed to detect this and erroneously failed to reject the null hypothesis. In other words, the user made an error in concluding that there is no significant effect or difference, when in fact there is.

b only

Step-by-step explanation:

Answer:

y = 1/4x or y = 0.25x

Step-by-step explanation:

In this question, we are trying to write an equation with the given points.

To solve this question, we would use the slope formula: y2-y1/x2-x1

Find the slope by plugging in variables:

2-1/8-4

1/4 = m

The slope would be 1/4

Find the y intercept:

To find the y-intercept, you would need to use the slope you've found and one point, and plug it into the slope-intercept equation:

1 = 1/4(4) + b

Solve:

1 = 1/4(4) + b

1 = 1 + b

Subtract 1 from both sides

0 = b

This means that the y-intercept is 0.

Our equation will be: y = 1/4x
