Answer:

  16

Step-by-step explanation:

Age problems can be solved by expressing the given relationships in math terms, then solving the resulting equation(s). Let J represent Judy's age now. Then Adami's age now is J/2. Six years ago, the relationship was ...

  (J -6) = 5(J/2 -6)

  J -6 = 2.5J -30

  24 = 1.5J

  16 = J

Judy is now 16 years old.

__

Additional comment

Adami is 8 now. 6 years ago, Judy was 10 and Adami was 2.

Here is an alternate approach. Let 'a' represent Adami's age 6 years ago. The relationship at present is ...

  2(a+6) = 5a +6

  6 = 3a . . . . . . . . . simplify, subtract 2a+6

  2 = a   ⇒   5a+6 = 16

Answer:

the slope is the rise over run so how ever many up it goes over how far side to side it goes these numbers are fractions and will very based on the rise over run.  

Step-by-step explanation:

The value of P'(5) = 65 and  P'(6) = 65.

Mr. Wutz owns a hot dog business called 'Wutz upDogs.' The daily profit function is given by P(x) = 65x + 7, where x is the number of hot dogs sold.

To evaluate P'(6), the derivative of P(x) at x = 6, we need to use the power rule for derivatives. The power rule states that d/dx(xn) = nxn-1. Therefore, P'(6) = 65(6)1 = 65 dollars per hot dog.

To evaluate P'(5), the derivative of P(x) at x = 5, we use the same power rule. Therefore, P'(5) = 65(5)1 = 65 dollars per hot dog.

The chemical tracer commonly used to trace the paths of afferent axons is called "biocytin."

Afferent nerve fibers are axons (nerve fibers) of sensory neurons that carry sensory information from sensory receptors to the central nervous system. Many afferent projections arrive at a particular brain region. Afferent nerve fiber.

The chemical tracer commonly used to trace the paths of afferent axons is called "biocytin." Biocytin is a modified form of biotin that can be taken up by neurons and transported along their axons. It is often injected into a specific region of interest and allowed to diffuse throughout the neural tissue. Afferent axons originating from the injected area can then take up and transport the biocytin, allowing researchers to visualize and study their pathways using various histological techniques, such as immunohistochemistry or avidin-biotin complex staining.

Answer: The shirt's price after reduction = $ 84.15

Step-by-step explanation:

Given: Price of shirt= $ 85

Marked up percent = 10%

Reduced percent = 10%

Price after mark up = (Price of shirt) + 10% of (Price of shirt)

= $ (85+10% x 85)

= $ (85+(0.1) x (85))

= $ (85+8.5)

= $ 93.5

Price after 10% reduction = (Price after mark up)- 10% of (Price after mark up)

= $ (93.5-0.1 x 93.5)

= $ (93.5-9.35)

= $ 84.15

Hence, the shirt's price after reduction = $ 84.15

Answer:

6,560

Step-by-step explanation:

Answer:

6,560

Step-by-step explanation:

We are given the first four terms of the sequence:

2, 6, 18, 54, ...

We need to find another four terms to find the sum.

I don't know how to explain how I got the pattern but you have to multiply by 3:

2 * 3 = 6

6 * 3 = 18

18 * 3 = 54

To find the next term, we will multiply 54 by 3:

54 * 3 = 162

2, 6, 18, 54, 162, ...

We now have 5 terms.

Next, multiply 162 by 3:

162 * 3 = 486

2, 6, 18, 54, 162, 486, ...

We now have 6 terms.

Next, multiply 486 by 3:

486 * 3 = 1458

2, 6, 18, 54, 162, 486, 1458, ...

We now have 7 terms.

Lastly, multiply 1458 by 3:

1458 * 3 = 4374

2, 6, 18, 54, 162, 486, 1458, 4374, ...

We now have the first 8 terms.

Now, we add all these numbers together:

2 + 6 + 18 + 54 + 162 + 486 + 1458 + 4374 = 6560

The sum of the first eight terms of the geometric sequence is 6,560

The vertex of the graph of f(x) = |x - 5| - 6 is (5, -6). It lies in the fourth quadrant.

Therefore the answer is (5, -6).

The graph f(x) = |x - 5| - 6 is symmetrical about the axis  x = 5.

A vertex of a graph is a node of a graph. For a graph of the form f(x) = a|x - h| + k, the vertex is (h, k). So in this case where f(x) = |x - 5| - 6, a = 1, h = 5 and k = -6. Therefore the vertex of the given graph f(x) is

Random sampling is most important to quantitative research methods.

Quantitative research relies on collecting numerical data and analyzing it statistically to draw conclusions about a population. Random sampling is a crucial aspect of quantitative research as it ensures that the sample selected is representative of the population being studied. By randomly selecting participants or data points from the population, researchers can minimize bias and increase the generalizability of their findings.

This allows them to make accurate inferences about the larger population based on the characteristics observed in the sample. Random sampling helps to reduce the potential for selection bias and ensures that each member of the population has an equal chance of being included in the sample, which enhances the validity and reliability of the research results.

The correct answer to the question is option d) 75 PCF.

To calculate the expected vertical load, we need to consider the weight of the concrete slab and the additional load due to the concrete's temperature and pouring rate. The weight of the slab can be calculated by multiplying the density of the concrete (150 PCF) by the depth (6 inches) and the area (1 square foot). This gives us a weight of 75 pounds per square foot (PSF).

The temperature and pouring rate do not directly affect the vertical load. The temperature and pouring rate are factors that may affect the structural integrity of the slab or the time it takes for the concrete to fully cure. However, they do not contribute to the actual load borne by the slab itself. Therefore, the correct answer is 75 PCF, as it represents the weight of the concrete slab alone.

Explanation:

The given table looks like this

\(\begin{array}{|c|c|} \cline{1-2}\text{number of rolls} & \text{number of people}\\\cline{1-2}1 & \\\cline{1-2}6 & 3\\\cline{1-2}10 & \\\cline{1-2}16 & \\\cline{1-2}25 & \\\cline{1-2}n & \\\cline{1-2}\end{array}\)

Focus on the row that has two values in it.

x = number of rolls = 6

y = number of people 3

k = constant of proportionality

y = kx

k = y/x = 3/6 = 0.5

The constant of proportionality is k = 0.5 which gives the direct variation equation of y = 0.5x

If x = 1, then y = 0.5*1 = 0.5 meaning that 1 roll feeds 0.5 people. This means we need 2 rolls to feed one person.

If x = 10, then y = 0.5x = 0.5*10 = 5 people can be fed with those 10 rolls. This process is continued until we finish filling out the table.

The final result is approximately 57 remainder 0.252608 in base 8.

To divide 10625 base 8 by 137 base 8, we can convert the numbers to base 10, perform the division, and then convert the result back to base 8.

Let's convert the numbers to base 10 first:

\(10625 base 8 = 1 \times 8^4 + 0 \times 8^3 + 6 \times 8^2 + 2 \times 8^1 + 5 \times 8^0\)

= 4096 + 0 + 384 + 16 + 5

= 4501

\(137 base 8 = 1 \times 8^2 + 3 \times 8^1 + 7 \times 8^0\)

= 64 + 24 + 7

= 95

Now we can perform the division:

4501 / 95 ≈ 47.378947

Since we are working with base 8, we need to convert the result back to base 8. The integer part of the result will be the quotient, and the fractional part will be used to find the digits of the remainder.

Quotient: 47 base 8

Remainder: \(0.378947 \times 8 = 3.031576\) (approximately)

Converting the quotient and remainder back to base 8:

Quotient: 47 base 8 =\(5 \times 8^1 + 7 \times 8^0 = 57\)base 8

Remainder: \(0.031576 \times 8 = 0.252608\) (approximately)

The function y = sin x / (1 + cos x) has a domain of all real numbers except for x = (2n + 1)π. It intersects the x-axis at x = nπ and the y-axis at y = 0. The function is symmetric about the y-axis. There  is a horizontal asymptote at y = -1. It increases on intervals where -π/2 < x < π/2 and decreases on intervals where π/2 < x < 3π/2. There are no local maximum or minimum values. The concavity of the function changes at x = nπ and there are no points of inflection.

A. The domain of the function y = sin x / (1 + cos x) includes all real numbers except for values of x that make the denominator equal to zero. In this case, the denominator is 1 + cos x, which is equal to zero when cos x = -1. Solving for x, we find x = (2n + 1)π, where n is an integer. Therefore, the domain is all real numbers except for x = (2n + 1)π.

B. To find the x-intercepts, we set y = 0 and solve for x. Setting sin x / (1 + cos x) = 0, we have sin x = 0. This equation is satisfied when x = nπ, where n is an integer. Hence, the function intersects the x-axis at x = nπ. The y-intercept is found by substituting x = 0 into the function, which gives y = 0 / (1 + 1) = 0.

C. The function y = sin x / (1 + cos x) is symmetric about the y-axis. This can be observed from the fact that replacing x with -x in the function does not change its value.

D. There are no vertical asymptotes for this function since the denominator is never zero. However, as x approaches positive or negative infinity, the function approaches a horizontal asymptote at y = -1.

E. The function increases on intervals where -π/2 < x < π/2 because the value of sin x is positive and the value of cos x is always greater than or equal to -1. It decreases on intervals where π/2 < x < 3π/2 because the value of sin x is negative while the value of cos x remains greater than or equal to -1.

F. The function y = sin x / (1 + cos x) does not have any local maximum or minimum values since it is always changing and never reaches a maximum or minimum point.

G. The concavity of the function changes at x = nπ, where n is an integer. Specifically, the function changes from concave up to concave down or vice versa at these points. However, there are no points of inflection where the concavity changes from concave up to concave down or vice versa.

H. Based on the information above, we can sketch the curve of the function. The curve will be symmetric about the y-axis, intersecting the x-axis at x = nπ and the y-axis at y = 0. It will approach a horizontal asymptote at y = -1 as x approaches positive or negative infinity. The curve will increase on intervals where -π/2 < x < π/2 and decrease on intervals where π/2 < x < 3π/2. There are no local maximum or minimum points, and the concavity changes at x = nπ, but there
