If x is a non-zero rational number and y is an irrational number, then y/x is irrational: TRUE

Assume that y/x is rational.

This means that we can write y/x as a fraction in the form a/b, where a and b are integers and b is non-zero.
y/x = a/b

Multiplying both sides by x, we get:
y = ax/b

Since x is a rational number, it can be expressed as a fraction in the form c/d, where c and d are integers and d is non-zero.
x = c/d

Substituting x with c/d in the above equation, we get:
y = ac/bd

Now, we have expressed y as a fraction, which contradicts the given fact that y is an irrational number. Hence, our assumption that y/x is rational must be false.
Therefore, y/x is irrational.

To solve the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0, we can use algebraic methods and the unit circle to determine the values of x that satisfy the equation.

1. Start by rearranging the equation to a quadratic form: \(6sin^2(x)\) + 6sin(x) + 1 = 0.

2. Notice that the equation resembles a quadratic equation in terms of sin(x). Let's substitute sin(x) with a variable, such as u: \(6u^2\) + 6u + 1 = 0.

3. Solve this quadratic equation for u. You can use the quadratic formula or factorization methods to find the values of u. The solutions are u = (-3 ± √3) / 6.

4. Since sin(x) = u, substitute back the values of u into sin(x) to obtain the values for sin(x): sin(x) = (-3 ± √3) / 6.

5. To find the values of x, we can use the inverse sine function. Take the inverse sine of both sides: x = arcsin[(-3 ± √3) / 6].

6. The arcsin function has a range of [-π/2, π/2], so the values of x lie within that range. Use a calculator to find the approximate values of x based on the values obtained in step 5.

7. Plot the obtained x-values on the graph to show the solutions of the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0. The graph will illustrate the points where the curve intersects the x-axis.

Answer: In order to calculate the bill for this household, we will need first to determine the total amount of water consumed in liters. Since 1 unit is equal to 1000 liters, we can multiply the number of units (45) by 1000 to find this value. 45 units * 1000 liters/unit = 45,000 liters

Next, we will need to determine the cost of the water consumed. Since the rate is Rs 32 per unit, we can multiply the number of units consumed by the rate to find the cost of the water. 45 units * Rs 32/unit = Rs 1440

Since the household consumed less than 10 units of water, they will be charged the minimum charge of Rs 100.

Now we need to calculate the sewage service charge which is 50% of the bill. So, Rs 1440 * 0.5 = Rs 720

Now we need to add the sewage service charge with the water bill and get the final bill. Rs 1440 + Rs 720 = Rs 2160

Since the payment is made within one month of the bill being issued, there is a 3% discount so that the final bill will be Rs 2160 - (3/100)*Rs 2160 = Rs 2094

So, the payment of the bill including a 50% sewage service charge if the payment is made within one month of the bill being issued would be Rs 2094.

Step-by-step explanation:

[1] Mass of evaporating dish #1: 36.190 g

[2] Mass of evaporating dish and original sample: 37.020 g

To calculate the mass of the original sample, we subtract the mass of the evaporating dish from the total mass:

Mass of original sample = Mass of evaporating dish and original sample - Mass of evaporating dish

Mass of original sample = 37.020 g - 36.190 g

Mass of original sample = 0.830 g

[3] Mass of evaporating dish after subliming NH4Cl(g): 36.550 g

To calculate the mass of NH4Cl(g), we subtract the final mass of the evaporating dish from the initial mass:

Mass of NH4Cl(g) = Mass of evaporating dish - Mass of evaporating dish after subliming NH4Cl(g)

Mass of NH4Cl(g) = 36.190 g - 36.550 g

Mass of NH4Cl(g) = -0.360 g (Note: The negative value indicates an error in measurement or calculation. Please double-check the data provided.)

To calculate the percent of NH4Cl (%), we use the formula:

Percent of NH4Cl = (Mass of NH4Cl(g) / Mass of original sample) * 100

Percent of NH4Cl = (-0.360 g / 0.830 g) * 100

Percent of NH4Cl = -43.37% (Note: The negative value also suggests an error. Please review the data carefully.)

Moving on to the determination of Sodium Chloride:

[4] Mass of evaporating dish #2: 41.63 g

[5] Mass of watch glass: 47.84 g

[6] Mass of evaporating dish #2, watch glass, and NaCl(g): 89.510 g

To calculate the mass of NaCl(g), we subtract the sum of the masses of the evaporating dish #2 and the watch glass from the total mass:

Mass of NaCl(g) = Mass of evaporating dish #2, watch glass, and NaCl(g) - (Mass of evaporating dish #2 + Mass of watch glass)

Mass of NaCl(g) = 89.510 g - (41.63 g + 47.84 g)

Mass of NaCl(g) = 89.510 g - 89.47 g

Mass of NaCl(g) = 0.040 g

To calculate the percent of NaCl (%), we use the formula:

Percent of NaCl = (Mass of NaCl(g) / Mass of original sample) * 100

Percent of NaCl = (0.040 g / 0.830 g) * 100

Percent of NaCl = 4.82%

To determine the change in angular momentum (ΔL) of a cylinder from t = 0 to t = t0, a student can use the equation:

ΔL = I * Δω

where ΔL is the change in angular momentum, I is the moment of inertia of the cylinder, and Δω is the change in angular velocity.

To calculate Δω, the student needs to know the initial and final angular velocities, ω0 and ωt0, respectively. The change in angular velocity can be calculated as:

Δω = ωt0 - ω0

Once Δω is determined, the student can use the moment of inertia (I) of the cylinder to calculate ΔL using the equation mentioned earlier.

The moment of inertia (I) depends on the mass distribution and shape of the cylinder. For a solid cylinder rotating about its central axis, the moment of inertia is given by:

I = (1/2) * m * r^2

where m is the mass of the cylinder and r is the radius of the cylinder.

By substituting the known values for Δω and I into the equation ΔL = I * Δω, the student can calculate the change in angular momentum (ΔL) of the cylinder from t = 0 to t = t0.

It's important to note that this method assumes that no external torques act on the cylinder during the time interval. If there are external torques involved, the equation for ΔL would need to include those torques as well.

The critical points are x = π/4 and x = 3π/4, and the extreme values on the interval [0,2] are 1/2 and -1/2,

To find the critical points of f(x) = 2 sin(x) cos(x) on the interval [0, 2] and determine the extreme values, we will first take the derivative of the function and set it equal to zero to find the critical points.

f(x) = 2 sin(x) cos(x)

f'(x) = 2 cos(x) cos(x) - 2 sin(x) sin(x) (using the product rule)

\(f'(x) = 2(cos^2(x) - sin^2(x))\)

f'(x) = 2(cos(2x))

Setting f'(x) equal to zero to find the critical points, we get:

2(cos(2x)) = 0

cos(2x) = 0

2x = π/2, 3π/2, 5π/2

x = π/4, 3π/4, 5π/4

Only the values x = π/4 and x = 3π/4 are in the interval [0,2], so these are the critical points.

Next, we need to determine the extreme values of f(x) at these critical points and the endpoints of the interval [0,2].

We can do this by evaluating the function at these points and comparing the values.

f(0) = 0

f(π/4) = 2(sin(π/4)cos(π/4)) = sin(π/2)/2 = 1/2

f(3π/4) = 2(sin(3π/4)cos(3π/4)) = -sin(π/2)/2 = -1/2

f(2) = 0

Therefore, the function has a maximum value of 1/2 at x = π/4 and a minimum value of -1/2 at x = 3π/4.

There are no extreme values at the endpoints of the interval [0,2].

Thus, the critical points are x = π/4 and x = 3π/4, and the extreme values on the interval [0,2] are 1/2 and -1/2, respectively.

The final answer is: π/4, 3π/4, 1/2, -1/2

Answer:

x = 7

y = 2

Step-by-step explanation:

In the above question, we are given 2 equations which are simultaneous. To solve this equation, we have to find the values of x and y

x + 3y = 13 ........ Equation 1

x - y = 5...........Equation 2

From Equation 2,

x = 5 + y

Substitute 5 + y for x in Equation 1

x + 3y = 13 ........ Equation 1

5 + y + 3y = 13

5 + 4y = 13

4y = 13 - 5

4y = 8

y = 8/4

y = 2

Since y = 2, substitute , 2 for y in Equation 2

x - y = 5...........Equation 2

x - 2 = 5

x = 5 + 2

x = 7

Using L'Hopital's rule, we can find that the limit is equal to (g(0) - 3)/2.

Since the line tangent to g at (0,3) has slope 2, we know that g(0) - 3 = 2(0) = 0. Therefore, the limit is 0/2 = 0. Based on the given information, we have a twice-differentiable function g(x) and its tangent line at the point (0,3). To find the value of the limit as x approaches 0 for g(x)e^(-x) - 3x^2 - 2x, we can use L'Hopital's rule since it involves indeterminate forms of the type 0/0 or ∞/∞.  Apply L'Hopital's rule twice on the given expression. Then, evaluate the resulting expression at x=0. This will give you the value of the limit for the given expression.

The bars in a histogram are not separated because the data being represented is continuous.

A histogram is a graphical representation of the distribution of data. Histograms are used to illustrate the frequency of data values in a set of information. They provide an estimation of the probability distribution of a continuous variable, which is critical for data analysis in numerous fields.

A histogram can be a bar chart with a frequency count, percentage frequency, or density. Histograms are used to visualize continuous data because they represent an estimation of the underlying probability density function of the random variable that produces the data.

Continuous data is quantitative data that can be measured and manipulated in fractions or decimal points. This data is often represented as a line on a graph. Discrete data, on the other hand, can only take on specific values that are distinct from one another.

Examples of discrete data are the number of pets you have or the number of cars in your garage. They can also be represented graphically as a bar graph because the information falls into discrete bins.

The property states that when two vectors a and b are multiplied together, the result is equal to the negative of b multiplied by a. This can be shown by multiplying the components of both vectors and then multiplying the result by -1.

a×b = (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1)

= (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1)

= (−1) * (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1)

= (−1) * (b2*a3 - b3*a2, b3*a1 - b1*a3, b1*a2 - b2*a1)

= − b × a.

The property a × b = − b × a states that when two vectors a and b are multiplied, the result is equal to the negative of b multiplied by a. This can be proven by first expanding the components of both vectors. For a vector a=(a1,a2,a3) and b=(b1,b2,b3), the expanded form of a×b is (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1). This can then be multiplied by -1 to get the expanded form of -b×a, which is (b2*a3 - b3*a2, b3*a1 - b1*a3, b1*a2 - b2*a1). Since this is equal to the original form of a×b, this proves the property.
