Answer:

p = 3

Step-by-step explanation:

Given

4(2 + px) = 12x

If the coefficient of the x- term is the same on both sides of the equation, it will have no solution.

Distributing gives

8 + 4px = 12x ( equate the coefficients of the x- term )

4p = 12 ( divide both sides by 4 )

p = 3

The value of p when the equation has no solution will be 3. Then the correct option is B.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

4(2 + px) = 12x

8 + 4px = 12x

If the coefficient of the x-term is the same on both sides of the equation, it will have no solution.

4p = 12

p = 3

The value of p when the equation has no solution will be 3. Then the correct option is B.

The perimeter of a rectangular painting is 332 centimeters. if the length of the painting is 92 centimeters, what is its width?

If the length and perimeter of the painting are 92 cm and 332 cm, then the width of the rectangular painting is 74 cm.

Given Parameters :

Length of the painting (l) = 92 cm

The perimeter of the painting (b) = 332 cm

The perimeter of a rectangle is given by

P = 2 (l + b)

Putting the values in the formula, we get:

332 = 2 (92 + b)

332 = 184 + 2b

2b = 332 - 184 = 148

2b = 148

b = 148/2 = 74 cm

The probability of picking three black cards in a row, without replacement, from a standard deck of 52 playing cards is 2/17, or approximately 0.1176 (rounded to four decimal places).

The probability of picking a black card on the first draw = 26/52 = 1/2

        (since there are 26 black cards in the deck)

The probability of picking a black card on the second draw, given that a one was picked on the first draw and the card is not replaced = 25/51,    

        (since there are now only 25 black cards left out)

The probability of picking a black card on the third draw, given that the ones picked on the first two draws are not replaced = 24/50 = 12/25,

        (since there are now only 24 black cards left out)

To pick three black cards in a row, we need to multiply the probabilities of each individual draw = (1/2) * (25/51) * (12/25) = 6/51

Simplifying this fraction, we get = 6/51 = 2/17

Yes, in this situation is it possible that lim x → 1 f(x) exists.

A horizontal/vertical oblique line that approaches 0 but never reaches it is known as an asymptote. Its distance from the graph of the function keeps becoming smaller.

What's the vertical asymptote rule?

Vertical asymptotes happen when a factor from a rational expression's denominator does not cancel out with a factor from the numerator.

                        The existence of a vertical asymptote occurs when a factor does not cancel, as opposed to creating a hole at that number. Using a dotted vertical line, the vertical asymptote is shown.

The ROI (Return on Investment) measures the profitability of an investment and is calculated by dividing the net profit by the cost of the investment.

The ROAS (Return on Advertising Spend) measures the effectiveness of an advertising campaign and is calculated by dividing the revenue generated by the advertising campaign by the cost of the campaign. Based on the information provided, it can be concluded that the business did better on the second campaign.


In this case, the business had an ROI of 3 for the first campaign and a ROAS of 4 for the second campaign.

To compare the two campaigns, we can look at the ratios.

For the first campaign, the ROI was 3, meaning that for every dollar invested, the business received 3 dollars in profit.

For the second campaign, the ROAS was 4, meaning that for every dollar spent on advertising, the business generated 4 dollars in revenue.

Comparing these two ratios, we can see that the second campaign had a higher return on advertising spend (ROAS) compared to the first campaign's return on investment (ROI). This suggests that the second campaign performed better in terms of generating revenue in relation to the advertising cost.

We have the following function:

The domain is the input values of the function, in this case, it would be the interval of values that x can take, while the range is the output values of the function, that is, in this case, it would be the interval of values that it can take y.

In the case of a reciprocal function, the domain is affected since the denominator can never be 0 since it generates a mathematical indeterminacy, therefore, we calculate the domain by setting the denominator equal to 0, just like this:

The range is affected by the fact that it can never be the value of 7, because the previous expression has no way of making it equal to 0, therefore the range would be:

Using the factor theorem and limits, it is found that the end behavior of g(x) is that it goes to negative infinity.

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

The Factor Theorem states that a function with leading coefficient a and zeros \(x_1, x_2, ..., x_n\) is defined by:

\(g(x) = a(x - x_1)(x - x_2)...(x - x_n)\)

In the given table, \(f(x) = 0\) for \(x = -4, x = 12\), thus the zeros are: \(x_1 = -4, x_2 = 12\)

Then, the definition is:

\(g(x) = a(x - (-4))(x - 12)\)

\(g(x) = a(x + 4)(x - 12)\)

\(g(x) = a(x^2 - 8x - 48)\)

The end behavior is the limit of g(x) as x goes to infinity, thus:

\(\lim_{x \rightarrow \infty} g(x) = \lim_{x \rightarrow \infty} ax^2 = a \times \infty\)

Since the leading coefficient a is negative:

\(a \times \infty = -\infty\)

Thus, the end behavior of g(x) is that it goes to negative infinity.

Therefore, the degree of the resulting polynomial is m + n when two polynomials of degree m and n are multiplied together.

What is polynomial?

A polynomial is a mathematical expression consisting of variables and coefficients, which involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and can be of different degrees, which is the highest power of the variable in the polynomial.

Here,

When two polynomials are multiplied, the degree of the resulting polynomial is the sum of the degrees of the original polynomials. In other words, if the degree of the first polynomial is m and the degree of the second polynomial is n, then the degree of their product is m + n.

This can be understood by looking at the product of two terms in each polynomial. Each term in the first polynomial will multiply each term in the second polynomial, so the degree of the resulting term will be the sum of the degrees of the two terms. Since each term in each polynomial has a degree equal to the degree of the polynomial itself, the degree of the resulting term will be the sum of the degrees of the two polynomials, which is m + n.

Answer:

114.96 pounds at angle 81.76°

Step-by-step explanation:

Let i be the component along x-axis and j be the component along y-axis.

First force that is given is 150 acting at angle 40; \(F1 = 150cos170i + 150sin40j = 114.91i +96.42j\)

The second force 100 is acting at angle 170;

\(F2 = 100cos170i + 100sin170j = -98.48i + 17.36j\)

We now have the resultant force, which is: \(114.91i + 96.42j + (-98.48i + 17.36j) = 16.43i + 113.78j\)

Magnitude of resultant:

\(\sqrt{16.43^{2} + 113.78^{2} }\) = 114.96 pounds

Angle it makes with horizontal; inverse tangent of \(\frac{(113.78)}{(16.43)}\) = 81.76 degrees

The implicit equation for the plane passing through the points (−4,−1,1) , (0,3,−4) , and (0,3,6) is: 2x - y + 3 = 0

To find the implicit equation for the plane passing through the points (−4,−1,1), (0,3,−4), and (0,3,6), we can first find two vectors that lie on the plane. We can choose the vectors formed by subtracting the first point from the other two points:

v1 = <0 - (-4), 3 - (-1), -4 - 1> = <4, 4, -5>

v2 = <0 - (-4), 3 - (-1), 6 - 1> = <4, 4, 5>

We can then find the normal vector of the plane by taking the cross product of these two vectors:

n = v1 x v2 = <4, 4, -5> x <4, 4, 5> = <-40, 20, 0>

The equation of the plane can then be written in the form:

-40(x - x0) + 20(y - y0) = 0

where (x0, y0, z0) is any point on the plane. We can use any of the three points given to find the equation of the plane. Let's use the point (0, 3, -4):

-40(x - 0) + 20(y - 3) = 0

Simplifying this equation, we get:

-40x + 20y - 60 = 0

Dividing both sides by -20, we get the final implicit equation of the plane:

2x - y + 3 = 0

The positive difference in the 'y' coordinates of where they agreed to meet and where they should actually meet is 4

Step-by-step explanation:

The segement they form is, using the distance formula,

\(d=\sqrt{((x1-x2)^2+(y1-y2)^2)}\)

but since we only need to find the y coordinates,

we do not need it in this case

now ,

in our case, x1 = 5, y1 = -11

x2=-7, y2=13

so,

y1-y2 is the total y difference for the first points,

so d1=-11-13

d1 = -24

but since distance is positive,so,

d1 = 24

and the midpoint of that would be m= d/2,

m1 = 12

if Barbara is at (-5,5), then the distance will be,

since then, x2=-5,y2=5,

d2 = -11-5

d2=-16

or,

d2 = 16

and

m2 = 16/2

m2 = 8

so the positive difference in the 'y' coordinates of where they agreed to meet and where they should actually meet is,

diff = 12-8

diff = 4

so the difference in y coordinates is 4
