The value of dI/da can be obtained by using the chain rule, which states that dI/da = (dI/dt) / (da/dt).

Given that I_dt = Floo and y = cos(4t^2) and y_dt = -8t*sin(4t^2), we can solve for dI/da by finding da/dt when t = 5 and substituting the values in the formula.

Let's first apply the chain rule to the equation y = cos(4t^2) to find dy/dt:

dy/dt = -sin(4t^2) * d/dt (4t^2) = -8t*sin(4t^2)

Next, we can use the given value I_dt = Floo, which means that dI/dt = 1.

To find da/dt, we need to differentiate a with respect to t. However, the value of a is not given explicitly in the equation. Therefore, we need to use the given information that when t = 5, a = -7. This means that we can write the equation for a as follows:

a = 5t - 42

Taking the derivative of both sides with respect to t, we get:

da/dt = 5

Now we can substitute the values we have found into the formula for dI/da:

dI/da = (dI/dt) / (da/dt) = 1 / 5 = 1/5

Therefore, the exact value of dI/da is 1/5.

Q10. Kₚ at 400°C is approximately 6.2x10¹⁶ and at 800°C is approximately 3.1x10³⁶.

Q11. To prepare a pH 3.50 solution, approximately 1 L of 2 mM H₂SO₄ solution is needed.

Q12. For a 0.100 M HIO₃ solution, the pH is approximately 0.126, [IO₃⁻] is negligible, and [OH⁻] is approximately 7.94 * 10⁻¹⁴ M.

Q13. To achieve a pH of 3 in a 250 ml solution, approximately 0.25 grams of benzoic acid (C₆H₅COOH) should be dissolved.

Q14. In a 0.55 M H₂SO₄ solution, the pH is approximately 1.30, [H₃O⁺] is approximately 0.0496 M, and [SO₄⁻] is 0.55 M.

Q10. To calculate Kₚ and K꜀ for the reaction at 400°C and 800°C, we use the Van't Hoff equation:

ln(K₂/K₁) = ΔH°/R * (1/T₁ - 1/T₂).

Given ΔH° = +115 kJ/mol and Kₚ at 25°C = 4.6x10¹⁴,

we find K₂ for 400°C and 800°C to be 6.2x10¹⁶ and 3.1x10³⁶, respectively.

Q11. To prepare a 2.1 L solution with pH 3.50, we use the equation pH = -log[H₃O⁺]. Converting pH to [H₃O⁺] concentration gives 3.2x10⁻⁴ M.

Using the relation [H₃O⁺] = [H₂SO₄], we find the required concentration of H₂SO₄ to be 2.1x10⁻² M.

To find the volume needed, we use the formula C₁V₁ = C₂V₂, where C₁ = 2 mM, C₂ = 2.1x10⁻² M, and V₂ = 2.1 L,

yielding V₁ ≈ 1 L.

Q12. For the 0.100 M HIO₃ solution, we can use the equation for the ionization of a weak acid,

Ka = [H₃O⁺][IO₃⁻]/[HIO₃]. Since [H₃O⁺] = [IO₃⁻],

we have [H₃O⁺]² = Ka * [HIO₃] = 0.016 * 0.100 M,

leading to [H₃O⁺] ≈ 0.126 M.

The [OH⁻] concentration can be calculated using Kw = [H₃O⁺][OH⁻] = 1 * 10⁻¹⁴, giving [OH⁻] ≈ 7.94 * 10⁻¹⁴ M.

Q13. To find the grams of benzoic acid (C₆H₅COOH) needed to make a 250 ml solution with pH 3, we first calculate the [H₃O⁺] concentration using pH = -log[H₃O⁺].

Thus, [H₃O⁺] = 10^(-3), which is approximately 7.94 * 10⁻⁴ M. Then, we use the acid dissociation constant (Ka) equation for benzoic acid: Ka = [H₃O⁺][C₆H₅COO⁻]/[C₆H₅COOH].

Since [H₃O⁺] ≈ [C₆H₅COO⁻], Ka ≈ 7.94 * 10⁻⁴. Next, we set up the expression for Ka and solve for [C₆H₅COOH] to get approximately 0.0100 M.

Finally, we use the formula m = C * V to find the grams of benzoic acid required, which comes out to be approximately 0.25 grams.

Q14. For the 0.55 M H₂SO₄ solution, we first consider the ionization of the first H⁺ to calculate the pH.

Using Ka₁ = [H₃O⁺][HSO₄⁻]/[H₂SO₄], we can approximate

[H₃O⁺] = [HSO₄⁻] = √(Ka₁ * [H₂SO₄])

          ≈ 0.0496 M.

Hence, the pH is approximately 1.30. As H₂SO₄ is a strong acid, its ionization is complete, resulting in [SO₄⁻] = 0.55 M. The [H₃O⁺] concentration remains the same as the initial concentration, i.e., 0.0496 M.

The slope of the line that passes through the points (-5, 6) and (-9, -6) is 3

What is slope ?

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).

Let the given points as shown:

(x1,y1)= (-5, 6) and (x2,y2)= (-9, -6)

Slope = m = (y2-y1) /( x2-x1)

                 = (-6-6) /(-9-(-5))

                 = -12/-4

                 = 3

The alternative hypothesis states that the difference is greater than zero.

What Are Tails in a Hypothesis Test?

First, we need to cover some background material to understand the tails in a test. Typically, hypothesis tests take all of the sample data and convert it to a single value, which is known as a test statistic. You’re probably already familiar with some test statistics.

For example, t-tests calculate t-values. F-tests, such as ANOVA, generate F-values. The chi-square test of independence and some distribution tests produce chi-square values. All of these values are test statistics.

Keep in mind that this t-distribution assumes that the null hypothesis is correct for the population. Consequently, the peak (most likely value) of the distribution occurs at t=0, which represents the null hypothesis in a t-test. Typically, the null hypothesis states that there is no effect. As t-values move further away from zero, it represents larger effect sizes. When the null hypothesis is true for the population, obtaining samples that exhibit a large apparent effect becomes less likely, which is why the probabilities taper off for t-values further from zero.

Hence the answer is the alternative hypothesis states that the difference is greater than zero.

The options that represent an amount and price of gas that Pedro purchased are 19 gallons of gas for $52.25, 16 gallons of gas for $44. So options C and D are correct.

To calculate the amount of gas and the total price that Pedro purchased, we need to use the formula:

Price = Cost per gallon * Number of gallons

Dividing the total price by the cost per gallon will give us the number of gallons purchased. We can then compare this with the given options to see which one(s) match.

Using the given cost per gallon of $2.75, we can check each option:

a) 13.75 gallons of gas for $41.25

Price = $2.75/gallon * 13.75 gallons = $37.81

This option does not match the total price of $41.25, so it is not correct.

b) 22 gallons of gas for $71.5

Price = $2.75/gallon * 22 gallons = $60.50

This option does not match the total price of $71.5, so it is not correct.

c) 19 gallons of gas for $52.25

Price = $2.75/gallon * 19 gallons = $52.25

This option matches the total price of $52.25, so it is correct.

d) 16 gallons of gas for $44

Price = $2.75/gallon * 16 gallons = $44

This option matches the total price of $44, so it is correct.

The statement that shows a discrepancy between the check register and bank statement is: C. Gavin: The balance in his check register is $500 and the balance in his bank statement is $510.

The check register shows a balance of $500, while the bank statement shows a balance of $510.

In the case of Gavin, where the balance in his check register is $500 and the balance in his bank statement is $510, there is a $10 discrepancy between the two.

A possible explanation for this discrepancy could be outstanding checks or deposits that have not yet cleared or been recorded in either the check register or the bank statement.

For example, Gavin might have written a check for $20 that has not been cashed or processed by the bank yet. Therefore, the check register still reflects the $20 in his balance, while the bank statement does not show the deduction.

After calculating the partial derivatives and the cross product, we can find the double integral of the magnitude over the region (0 ≤ r ≤ √3, 0 ≤ θ ≤ 2π). This double integral gives the surface area of the part of the plane inside the cylinder.

To find the area of the surface of the part of the plane x + 2y + 3z = 1 that lies inside the cylinder x^2 + y^2 = 3, we can use a parametric representation for the plane and cylinder intersection.

Let x = r * cos(θ) and y = r * sin(θ), where r^2 = 3 (from the cylinder equation). Now, we can find z in terms of r and θ using the plane equation:

z = (1 - x - 2y) / 3
z = (1 - r * cos(θ) - 2r * sin(θ)) / 3

Now, we have the parametric representation of the intersection: (r * cos(θ), r * sin(θ), (1 - r * cos(θ) - 2r * sin(θ)) / 3). To find the surface area, we need to calculate the partial derivatives with respect to r and θ and then find the magnitude of the cross product.

The fluid force on the sheet metal's top side when submerged horizontally in 7 feet of water is 12441.6 lb.

Given,

The area of the top side of a piece of sheet metal = 4 square feet

The sheet metal is submerged horizontally in 7 feet of water.

Fluid Force on the top side can be found as follows,

Formula used:

Fluid Force = weight-density × volume × depth of fluid

Fluid Force = 62.4 × volume × 7

As the sheet metal is completely submerged, the volume is equal to the area of the sheet metal.

Volume = Area × Depth

= 4 × 7

= 28

Fluid Force = 62.4 × 28 × 7

                   = 12441.6 lb

Thus, the fluid force on the sheet metal's top side when submerged horizontally in 7 feet of water is 12441.6 lb.

Therefore, the fluid force on the top side is 55838.08 lb.

Given, the area of the top side of a piece of sheet metal is 4 square feet and it is submerged horizontally in 7 feet of water.

The weight-density of water is 62.4 pounds per cubic foot.To find: the fluid force on the top side.Solution:Fluid force formula is given by,

F = ρ * g * V

Where, ρ is the density of the fluidg is the acceleration due to gravityV is the volume of the fluid displaced.Furthermore, the volume of fluid displaced is equal to the volume of the metal sheet submerged in the water.

Therefore,Volume of fluid displaced = Volume of metal sheet submerged in the water = area of metal sheet * depth submerged

Volume of metal sheet submerged in the water = 4 square feet * 7 feet

= 28 cubic feet

Now, calculate the fluid force on the top side of the metal sheet by using the fluid force formula.

F = ρ * g * V

Here, the density of water,

ρ = 62.4 pounds per cubic foot

g = 32.2 ft/s² (the acceleration due to gravity)

V = 28 cubic feet∴

F = 62.4 * 32.2 * 28 lb

= 55838.08 lb

Answer:

Point M will be located between 0 and 1 at \(\frac{1}{13}\).

Step-by-step explanation:

Two points A and B have been given on a number line.

Point A is at -3 and point B at 7.

Distance between these points AB = 7 - (-3)

                                                           = 7 + 3

                                                           = 10 units

Another point M divides the given segment AB in the ratio of 4 : 9.

Therefore, length of segment AM will be = \(\frac{4\times 10}{(4+9)}\)

                                                                    = \(\frac{40}{13}\)

                                                                    = \(3\frac{1}{13}\) units

Now the position of point M will be at \((-3+3\frac{1}{13})\) = \(\frac{1}{13}\)

Therefore, point M will be located between 0 and 1 at \(\frac{1}{13}\).
