Answer: d

Step-by-step explanation:

Let x be the smaller angle and y be the larger angle. Since the measure of the larger angle y is 8 times the measure of the smaller angle x, it follows:

\(y=8x\)

Since x and y form a linear pair, so the sum of their measures is equal to 180 degrees as follows:

\(x+y=180^{\circ}\\x+8x=180^\circ\\9x=180^\circ\\x=20^{\circ}\)

Then, it follows:

\(y=8x=8\cdot 20^{\circ}=160^{\circ}\)

So, the measure of the larger angle is \(160^{\circ}\).

The expression (15x - 6) / (7x - 6), where no denominator equals zero, is equivalent to (15x - 6) / (7x - 6).

To simplify the expression (15x - 6) / (7x - 6), we can start by factoring the numerator and the denominator if possible. However, since no denominator can equal zero, we need to ensure that the expression 7x - 6 is not equal to zero. Let's solve the equation 7x - 6 = 0 to find the value of x that makes the denominator zero.

7x - 6 = 0

7x = 6

x = 6/7

Since x = 6/7 is the value that makes the denominator zero, we cannot use this value in our simplified expression. Therefore, we need to exclude x = 6/7 from the domain of the expression.

Now, let's consider the remaining values of x that do not make the denominator zero. We can simplify the expression by dividing both the numerator and the denominator by their greatest common divisor. In this case, the greatest common divisor of 15x - 6 and 7x - 6 is 1 since there are no common factors other than 1.

Dividing both the numerator and the denominator by 1 yields:

(15x - 6) / (7x - 6)

Since we cannot further simplify the expression due to the restriction on the domain, the simplified form of the expression, where no denominator equals zero, is:

(15x - 6) / (7x - 6)

In summary, the expression (15x - 6) / (7x - 6), where no denominator equals zero, is equivalent to (15x - 6) / (7x - 6).

Step-by-step explanation:

The statement "int grades[] = { 100, 90, 99, 80 };" initializes an integer array called "grades" with the values 100, 90, 99, and 80. The given statement is an example of initializing an integer array in C++.

The array is named "grades" and has an unspecified size denoted by the empty square brackets []. The values inside the curly braces { } represent the initial values of the array elements.

In this case, the array "grades" is initialized with four elements: 100, 90, 99, and 80. The first element of the array, grades[0], is assigned the value 100, the second element, grades[1], is assigned 90, the third element, grades[2], is assigned 99, and the fourth element, grades[3], is assigned 80.

The array can be accessed and manipulated using its index values. This type of initialization allows you to assign initial values to an exhibition during its declaration conveniently.

The integral θ(r)=∫⎝⎛±2μ(E−U−2μr2l2)l/r2dr⎞⎠⎟+constant gives the change in the angle θ of a body undergoing orbital motion as a function of the radius r.

The integral θ(r)=∫⎝⎛±2μ(E−U−2μr2l2)l/r2dr⎞⎠⎟+constant is a result of the conservation of angular momentum. The angular momentum of a body is defined as the product of its mass, its velocity, and the distance from the center of rotation.

In the case of orbital motion, the velocity of the body is given by v=rω, where ω is the angular velocity. The angular momentum is then l=mrv=mr2ω.

The conservation of angular momentum states that the angular momentum of a body remains constant unless an external torque is applied. In the case of orbital motion, the only external torque is the gravitational force.

The gravitational force is always perpendicular to the velocity, so it does not change the magnitude of the angular momentum. However, it does change the direction of the angular momentum, which is why the body undergoes orbital motion.

The integral θ(r)=∫⎝⎛±2μ(E−U−2μr2l2)l/r2dr⎞⎠⎟+constant can be derived by using the conservation of angular momentum and the equation for the gravitational force. The integral gives the change in the angle θ of the body as a function of the radius r. The ± sign in the integral represents the two possible directions of rotation.

The integral θ(r)=∫⎝⎛±2μ(E−U−2μr2l2)l/r2dr⎞⎠⎟+constant is a powerful tool for studying orbital motion. It can be used to calculate the change in the angle of the body as it moves along its orbit, and it can also be used to calculate the total energy of the body.

There are several different sampling methods that could be employed for this study, including:

Simple random sampling: This method involves randomly selecting a certain number of students from each campus and measuring the distance between their hometowns and their campuses.

Stratified random sampling: This method involves dividing the student population at each campus into different strata (e.g. by major or year in school) and then randomly selecting a certain number of students from each stratum.

Cluster sampling: This method involves randomly selecting a certain number of campuses and then measuring the distance between the hometowns of all students at those campuses and their respective campuses.

Multi-stage sampling: This method involves using a combination of the above methods, such as first using cluster sampling to select a certain number of campuses and then using stratified random sampling to select a certain number of students from each campus.

This study would be an enumerative study because it seeks to measure the characteristics of a population, in this case, the average distance between the hometowns of students and their campuses, by counting and measuring them.

It is not an analytic study because it doesn't involve testing a hypothesis or making causal inferences.

This value represents the present worth below which the probability is 0.5, indicating a negative present worth.

To estimate the probability that the present worth is negative using the NORM.INV function in Excel,

we need to calculate the present worth of the project and then determine the corresponding probability using the normal distribution.

The present worth of the project can be calculated by finding the sum of the present values of the annual receipts over the 10-year period, minus the initial investment. The present value of each annual receipt can be calculated by discounting it back to the present using the minimum attractive rate of return (MARR).

Using the given information, the present value of the initial investment is $10,000. The present value of each annual receipt is calculated by dividing the expected return of $1,800 by \((1+MARR)^t\),

where t is the year. We then sum up these present values for each year.

We can use the NORM.INV function in Excel to estimate the probability of a negative present worth. The function requires the probability value, mean, and standard deviation as inputs.

Since we have a mean and standard deviation for the present worth,

we can calculate the corresponding probability of a negative present worth using NORM.INV.

This value represents the present worth below which the probability is 0.5. By using the NORM.INV function,

we can estimate the probability that the present worth is negative based on the given data and assumptions.

When one dimension of a prism is doubled, the volume of the prism also doubles. When two dimensions are doubled, the volume increases by a factor of four. When all three dimensions are doubled, the volume increases by a factor of eight.

The volume of a prism is determined by multiplying its base area by its height. Let's consider a prism with dimensions length (L), width (W), and height (H). If one dimension is doubled, let's say the length (L), the new length becomes 2L. Since volume is proportional to the product of the dimensions, the new volume is calculated as (2L) * W * H, which simplifies to 2(L * W * H). Therefore, the volume doubles when one dimension is doubled.

Similarly, when two dimensions are doubled, let's say the length (L) and width (W), the new length becomes 2L and the new width becomes 2W. The new volume is calculated as (2L) * (2W) * H, which simplifies to 4(L * W * H). Hence, the volume increases by a factor of four when two dimensions are doubled.

When all three dimensions are doubled, each dimension becomes twice its original value. So, the new volume is calculated as (2L) * (2W) * (2H), which simplifies to 8(L * W * H). Consequently, the volume increases by a factor of eight when all three dimensions are doubled.

In summary, doubling one dimension doubles the volume, doubling two dimensions increases the volume by a factor of four, and doubling all three dimensions increases the volume by a factor of eight.

The titration curve for a spectrometric titration of A(analyte) by adding B (titrant), the volume of B at end point is 100 ml and absobance at this point is equals to zero. So, option(c) is right one.

We have a spectrometric titration with A (analyte) B (titrant) = C + D ( products)

In the spectrophotometric titration of the colored substrat and colored titrant to produce colorless products, the absorbance is maximum intially because both the analyte and the titrant are colored. The absorbance of the solution decreases with the addition if the titrant due to the formation of the colorless products. The abosrbance becomes zero at the end point where the reaction undergoes completion and all substrate is converted into products. Then, the absorbance of the solution again increases due to the addition of the colored titrant solution. The titration curve is present in attached figure. At end point volume of B can be determined by following equation, \(M_A V_A = M_B V_B \)

where M --> represents molarity

V --> volume

here \( M_A =0.001 M , M_B = 0.001 M\) and \(V_A = 100 ml \).

So, \(0.001 (100) = (0.001 ) V_B\)

=> \(V_B = 100 ml\)

As the products C and D are colourless, so at that point absorbance is equals to the zero. Hence, Volume 100 ml, of B is added and absorbance is zero.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted ΔABC.

In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

Given is ΔQPL, such that the m∠Q is five times the m∠P and m∠L is 12 more than twice the m∠P. It is also the larger acute angle is 10 degree less then three times the measure of smaller acute angle.

[1] - It is given that -

∠Q = 5∠P

∠L = 2∠P + 12

For the triangle ΔQPL, we can write -

∠Q + ∠P + ∠L = 180

5∠P + 2∠P + 12 + ∠P = 180

8∠P = 168

∠P = 21°

∠Q = 5∠P = 5 x 21 = 105°

∠L = 2∠P + 12 = 2 x 21 + 12 = 54°

[2] -

Assume that the larger acute angle is [x] and the smaller angle be [y]. Then -

x = 3y - 10

Then -

x + y + 90 = 180

3y - 10 + y + 90 = 180

4y = 100

y = 25

x = 3 x 25 - 10

x = 65
