The value of k in the joint variation equation is 2.

To solve this problem, we need to determine the constant of variation, denoted as k, in the joint variation equation.

The joint variation equation is expressed as f = k * q^2 * h, where f is the dependent variable, q is one of the independent variables, h is another independent variable, and k is the constant of variation.

Given that f = 96 when q = 4 and h = 3, we can substitute these values into the equation to find the value of k.

96 = k * 4^2 * 3

96 = 16k * 3

96 = 48k

k = 96 / 48

k = 2

Therefore, the value of k is 2. This means that f varies jointly as q^2 and h with a constant of variation equal to 2.

Heracio used the computer 4 more hours to do homework than shop online.

To find out how many more hours Heracio used the computer to do homework than shop online, we first need to calculate the number of hours he spent on each activity.

Let's start by calculating the number of hours Heracio spent on each activity:

Shopping: 10% of 40 hours = 4 hours

Videos: 15% of 40 hours = 6 hours

Homework: 20% of 40 hours = 8 hours

Games: 20% of 40 hours = 8 hours

Social media: 25% of 40 hours = 10 hours

Now, to find out how many more hours Heracio used the computer to do homework than shop online, we need to subtract the number of hours spent shopping from the number of hours spent on homework:

8 hours (homework) - 4 hours (shopping) = 4 hours

Therefore, Heracio used the computer 4 more hours to do homework than shop online.

Answer: \(14*\sqrt[3]{x^{10}}\)

Step-by-step explanation:

First, let's remember the rules:

\(x^{1/n} = \sqrt[n]{x}\)

such that:

\(\sqrt[n]{x^m} = x^{m/n}\)

\((x^a)^b = x^{a*b}\)

\(x^a*x^b = x^{a + b}\)

Now we have the equation:

\(4*\sqrt[3]{x^{10}} + 5*x^3*\sqrt[3]{8*x}\)

First, let's rewrite the roots as we saw above:

\(4*x^{10/3} + 5*x^3*\sqrt[3]{8}*x^{1/3} = 4*x^{10/3} + 5*\sqrt[3]{8}*x^{3 + 1/3}\)

We also know that: \(\sqrt[3]{8} = 2\)

and that:  \(3 + 1/3 = 9/3 + 1/3 = 10/3\)

Replacing those two things in our equation, we get:

\(4*x^{10/3} + 5*\sqrt[3]{8}*x^{3 + 1/3} = 4*x^{10/3} + 5*2*x^{10/3} = (4 + 5*2)*x^{10/3}\)

\((4 + 10)*x^{10/3} = 14*\sqrt[3]{x^{10}}\)

The function m(x) = 2tan(3x+4) is obtained by applying a sequence of transformations to the parent tangent function.

To determine the sequence of transformations, let's break down the given function:

1. Inside the tangent function, we have the expression (3x+4). This represents a horizontal compression and translation.

2. The coefficient 3 in front of x causes the function to compress horizontally by a factor of 1/3. This means that the period of the function is shortened to one-third of the parent tangent function's period.

3. The constant term 4 inside the parentheses shifts the function horizontally to the left by 4 units. So, the graph of the function is shifted to the left by 4 units.

4. Outside the tangent function, we have the coefficient 2. This represents a vertical stretch.

5. The coefficient 2 multiplies the output of the tangent function by 2, resulting in a vertical stretch. This means that the graph of the function is stretched vertically by a factor of 2.

In summary, the sequence of transformations applied to the parent tangent function to create the function m(x) = 2tan(3x+4) is a horizontal compression by a factor of 1/3, a horizontal shift to the left by 4 units, and a vertical stretch by a factor of 2.

Example:
Let's consider a point on the parent tangent function, such as (0,0), which lies on the x-axis.

After applying the transformations, the corresponding point on the function m(x) = 2tan(3x+4) would be:
(0,0) -> (0,0) (since there is no vertical shift in this case)

This example helps illustrate the effect of the transformations on the graph of the function.

Based on the direct variation relationship between x and y, where y is 33 when x is 11, we find that y is 36 when x is 12.

If x and y vary directly, it means that they have a constant ratio between them. We can express this relationship as:

y = kx,

where k is the constant of variation.

To find the value of k, we can use the given information that when x is 11, y is 33. Substituting these values into the equation, we have:

33 = k * 11.

Dividing both sides by 11, we find:

k = 3.

Now that we have determined the constant of variation, we can find y when x is 12 by substituting this value into the equation:

y = 3 * 12.

Evaluating this expression, we get:

y = 36.

Therefore, when x is 12, y will be 36.

Based on the direct variation relationship between x and y, where y is 33 when x is 11, we find that y is 36 when x is 12.

6/7 of people are not having a disease, the whole is 1 so the difference is:

2/3 of those having a disease is:

15 people are the 1/7 fraction of total people referred to quarantine.

The total number is:

3/5 of 105 people are male, that is:

Number of female is:

Answer:

\(\sf (i) \quad \dfrac{1}{7}\)

\(\sf (ii) \quad \dfrac{2}{21}\)

\(\sf (iii) \quad 315\:people\)

\(\sf (iv) \quad 126\: females\)

Step-by-step explanation:

If 6/7 of people who are quarantined do not have the disease then the fraction of people that do have the disease is:

\(\begin{aligned} \implies 1-\dfrac{6}{7} & =\dfrac{7}{7}-\dfrac{6}{7}\\\\ & =\dfrac{7-6}{7}\\\\ & =\dfrac{1}{7}\end{aligned}\)

Therefore, 1/7 of people in quarantine have the disease.

We are told that 2/3 of the people who have the disease come from abroad.  Therefore, the fraction of diseased people coming from abroad is 2/3rds of the diseased people:

\(\begin{aligned} \implies \dfrac{2}{3} \textsf{ of }\dfrac{1}{7} & = \dfrac{2}{3} \times \dfrac{1}{7}\\\\ & = \dfrac{2 \times 1}{3 \times 7}\\\\ & = \dfrac{2}{21}\end{aligned}\)

Therefore, the fraction of diseased people who have come from abroad is 2/21.

We are told that 15 people who have the disease do not come from abroad.  So if 2/3 of the people who have the disease come from abroad, then 1/3 of the people who have the disease do not come from abroad.  Remember that 1/7 of the total people have the disease.

\(\begin{aligned} \implies \dfrac{1}{3} \textsf{ of }\dfrac{1}{7} & = \dfrac{1}{3} \times \dfrac{1}{7}\\\\ & = \dfrac{1 \times 1}{3 \times 7}\\\\ & = \dfrac{1}{21}\end{aligned}\)

Therefore, 1/21 of the total number of people have the disease and do not come from abroad.

Therefore, 15 people are equal to 1/21 of the total number of people:  

\(\implies \sf Total\:number\:of\:people=15 \times 21 = 315\)

Therefore, the total number of people in quarantine is 315.

If 3/5 of the total are male, then 2/5 must be female.

\(\begin{aligned} \implies \dfrac{2}{5} \textsf{ of }315 & = \dfrac{2}{5} \times 315\\\\ & = \dfrac{2 \times 315}{5}\\\\ & = \dfrac{630}{5}\\\\& = 126 \end{aligned}\)

Therefore, 126 females are in quarantine.
