Answer: x = -8

Step-by-step explanation:

12 ( x + 10 ) = 24

First we divide the two sides of the exercise by 12.

\(\boldsymbol{\sf{x+10=\dfrac{24}{12} }}\)

We divide 24 by 12..

x + 10 = 2

Subtract 10 from both sides.

x = 2 - 10

Subtract 10 from 2 to get. Since the number 10 is greater than 2, the result will be negative.

x = -8

Answer:

\( \sf \: x = - 8\)

Step-by-step explanation:

Given equation,

→ 12(x + 10) = 24

Now the value of x will be,

→ 12(x + 10) = 24

→ 12(x) + 12(10) = 24

→ 12x + 120 = 24

→ 12x = 24 - 120

→ 12x = -96

→ x = -96 ÷ 12

→ [ x = -8 ]

Hence, the value of x is -8.

If the perimeter of a rectangle is 24 feet and one of the sides has a length of x feet, the area of the rectangle is A = x (12 - x).

Let's consider a rectangle with one side measuring x feet. The perimeter of a rectangle is given by the formula

P = 2(l + w), where P represents the perimeter, l represents the length, and w represents the width.

In this case, since one of the sides has a length of x, we can substitute the values in the formula as follows:

24 = 2(x + w)

Simplifying the equation, we have

12 = x + w

To find the area of the rectangle, we use the formula A = lw, where A represents the area, l represents the length, and w represents the width. Since we know that one of the sides has a length of x, we can substitute x for the length, resulting in

A = xw

To determine the value of the width, we can rearrange the equation

12 = x + w to express w in terms of x, which gives w = 12 - x.

Substituting this value into the area formula, we have

A = x(12 - x)

This expression represents the area of the rectangle in terms of x.

The statement is: B. False. The center would be expected to attract about 72 employees.

To determine whether the statement is true or false, we need to consider the given information about the distribution of ages among clerical employees.

The statement claims that a training program for employees under the age of 30 at the center would be expected to attract about 36 employees.

Since the age of the clerical employees follows a normal distribution with a mean of 38 and a standard deviation of 6, we can use the properties of the normal distribution to evaluate the statement.

To calculate the number of employees under the age of 30, we need to find the proportion of employees within that age range. We can then multiply this proportion by the total number of employees (400) to estimate the number of employees under 30.

Using a standard normal distribution table or a calculator, we can find the z-score corresponding to an age of 30, given a mean of 38 and a standard deviation of 6.

z = (x - μ) / σ

z = (30 - 38) / 6

z = -1.33

Looking up the corresponding area under the standard normal curve for z = -1.33, we find that the proportion of employees under the age of 30 is approximately 0.0918.

To estimate the number of employees under 30, we multiply this proportion by the total number of employees:

Number of employees under 30 = 0.0918 * 400 ≈ 36.72

The estimated number of employees under 30 is approximately 36.72.

Therefore, the statement is: B. False. The center would be expected to attract about 72 employees.

The expression sin(e^37) does not have a well-defined limit as x approaches 0 from the left side since the argument e^37 is not an angle and is a constant.

To find the limit of the function sin(e^37) as x approaches 0 from the left side, we need to evaluate the limit and analyze the behavior of the function near 0.

The expression sin(e^37) represents the sine of a very large number, approximately equal to 5.32048241 × 10^16. The sine function oscillates between -1 and 1 as the input increases, but it does so in a periodic manner.

As x approaches 0 from the left side (x < 0), the function sin(e^37x) will oscillate rapidly between -1 and 1. However, since the argument of the sine function (e^37) is an extremely large constant, the oscillations will occur at a much higher frequency.

To calculate the limit, we can directly evaluate the function at x = 0 from the left side.

sin(e^37 * 0) = sin(0) = 0.

Therefore, the limit of sin(e^37) as x approaches 0 from the left side is equal to 0.

The maximum value of P = 9x + 8y subject to the given constraints is 64, and it occurs when x = 0 and y = 8.

To find the maximum value of P = 9x + 8y subject to the given constraints, we need to analyze the feasible region determined by the inequalities.

First, let's find the y-intercept of the first inequality: 8x + 6y <= 48.

To find the y-intercept, we set x = 0 and solve for y:

8(0) + 6y ≤ 48

6y ≤ 48

y ≤ 48/6

y ≤ 8

Therefore, the y-intercept of the first inequality is 8.

Next, let's graph the feasible region determined by the inequalities:

8x + 6y ≤ 48

7x + 7y ≤ 49

x ≥ 0

y ≥ 0

The feasible region is a quadrilateral bounded by the x-axis, y-axis, and the lines 8x + 6y = 48 and 7x + 7y = 49.

The region lies in the first quadrant and has vertices at (0, 0), (0, 8), (6, 1), and (7, 0).

To find the maximum value of P = 9x + 8y within this region, we evaluate P at each vertex and determine the maximum value.

P(0, 0) = 9(0) + 8(0) = 0

P(0, 8) = 9(0) + 8(8) = 64

P(6, 1) = 9(6) + 8(1) = 54 + 8 = 62

P(7, 0) = 9(7) + 8(0) = 63 + 0 = 63

Therefore, the maximum value of P = 9x + 8y within the feasible region is 64, which occurs at the vertex (0, 8).

The velocity of airflow during a respiratory cycle is given by v = 0.85 sin(pi t/3) ,t- time in s. One full respiratory cycle takes 6 s, and there are 10 cycles per min. The graph of the velocity function is a sinusoidal wave with amplitude 0.85 and period 6 s.

The given function for velocity during a respiratory cycle is v = 0.85 sin(pi t/3). The velocity is positive during inhalation and negative during exhalation. To find the time for one full respiratory cycle, we need to solve for the values of t that make v=0:

0 = 0.85 sin(pi t/3)

sin(pi t/3) = 0

pi t/3 = n pi

t = 3n, where n is an integer

Thus, one full respiratory cycle takes 6 seconds (when n=2). To find the number of cycles per minute, we can use the formula:

cycles per minute = 60 / time per cycle

Substituting the value of time per cycle, we get:

cycles per minute = 60 / 6 = 10

Therefore, there are 10 cycles per minute.

The graph of the velocity function is a sinusoidal wave with amplitude 0.85 and period 6 seconds. The function starts at 0, reaches a maximum value of 0.85 at t=3 seconds, goes through 0 again at t=6 seconds, reaches a minimum value of -0.85 at t=9 seconds, and returns to 0 at t=12 seconds. The graph repeats itself every 6 seconds, which is the period of the function. Thus, the graph is a sinusoidal wave that oscillates between positive and negative values with a frequency of 1/6 Hz (or 10 cycles per minute).

Answer:

The total charge on the rod is approximately 12.6424nC, or 2.0nC considering the correct significant figures.

To find the total charge on the rod, we need to integrate the charge density function over the length of the rod. Given that the charge density is non-uniform and varies with position along the rod, we can express the charge density as a function of x, where x is the distance from the left end of the rod.

The charge density function is given as λ(x) = (2.0nC/cm) * e^(-x/10).

To find the total charge, we integrate the charge density function from x = 0 to x = 10 cm:

Q = ∫(0 to 10) λ(x) dx.

Substituting the given charge density function into the integral, we have:

Q = ∫(0 to 10) (2.0nC/cm) * e^(-x/10) dx.

Integrating this expression gives us:

Q = -20nC * [e^(-x/10)] evaluated from 0 to 10.

Evaluating the expression at x = 10 and subtracting the value at x = 0, we get:

Q = -20nC * (e^(-10/10) - e^(0/10)).

Simplifying further:

Q = -20nC * (e^(-1) - 1).

Using the value of e (approximately 2.71828), we can calculate:

Q = -20nC * (2.71828^(-1) - 1).

Q ≈ -20nC * (0.36788 - 1).

Q ≈ -20nC * (-0.63212).

Q ≈ 12.6424nC.

Taking the absolute value of the charge (since charge cannot be negative), we find:

Q ≈ |12.6424nC|.

Therefore, the total charge on the rod is approximately 12.6424nC, or 2.0nC considering the correct significant figures.

Answer: 1182

Step-by-step explanation:

Answer:If p and q vary inversely, it means that their product remains constant. So we can set up the equation:

p * q = k

where k is the constant of variation.

Given that p is 29 when q is 25, we can substitute these values into the equation:

29 * 25 = k

725 = k

Now, let's determine the value of q when p is equal to 5:

p * q = k

5 * q = 725

q = 725 / 5

q = 145

The term 2/0 is undefined as it represents division by zero. Therefore, for b = 1.5, the integral ∫(0 to 1) 1/x^1.5 dx is not well-defined, and it does not converge. In summary, it is not possible to find a real number b > 0 such that the integral ∫(0 to 1) 1/x^b dx converges.

To find a real number b > 0 such that the integral ∫(0 to 1) 1/x^b dx converges, we need to ensure that the integrand function is integrable over the given interval.

Let's consider b = 2 as an example. In this case, the integral becomes:

∫(0 to 1) 1/x^2 dx

To evaluate this integral, we can use the antiderivative of 1/x^2, which is -1/x. Applying the Fundamental Theorem of Calculus, we have:

∫(0 to 1) 1/x^2 dx = [-1/x] evaluated from 0 to 1

= [-1/1 - (-1/0)]

However, the term -1/0 is undefined as it represents division by zero. Therefore, for b = 2, the integral ∫(0 to 1) 1/x^2 dx is not well-defined, and hence, it does not converge.

To find a suitable value of b such that the integral converges, we need to choose a value where the function 1/x^b remains integrable over the interval (0, 1). In other words, we need b > 1.

For example, let's choose b = 1.5. In this case, the integral becomes:

∫(0 to 1) 1/x^1.5 dx

We can evaluate this integral using the antiderivative of 1/x^1.5, which is 2/x^0.5. Applying the Fundamental Theorem of Calculus, we have:

∫(0 to 1) 1/x^1.5 dx = [2/x^0.5] evaluated from 0 to 1

= [2/1 - 2/0]

Again, the term 2/0 is undefined as it represents division by zero. Therefore, for b = 1.5, the integral ∫(0 to 1) 1/x^1.5 dx is not well-defined, and it does not converge.

In summary, it is not possible to find a real number b > 0 such that the integral ∫(0 to 1) 1/x^b dx converges.

The correlation coefficient (r) measures the strength and direction of the relationship between two variables. If the heart disease death rate is expressed as deaths per 1,000 people instead of as deaths per 100,000 people, it would change the units in which the death rate is expressed, but it would not change the underlying relationship between wine consumption and heart disease death rate.

In other words, regardless of the units in which the death rate is expressed, the correlation between wine consumption and heart disease death rate would remain the same. This is because the correlation measures the relationship between two variables, not the units in which they are expressed. It is important to note that expressing the death rate in different units may make it easier or more difficult to understand the relationship between two variables, but it does not change the underlying correlation.
