Answer:

y= \(\frac{2}{5}\)(x)+2

Step-by-step explanation:

First take two points from the line (x-int (-5,0) and y-int (0,2)). Once you get that you want to find the slope using the formula \(\frac{Y_{2} -Y_{1} }{X_{2}- x_{1} }\). Substitute the values and find the slope. Once you find the slope (m) to be \(\frac{2}{5}\), take any of the two points and apply it to the slope intercept formula (y=mx+b) to find b. I took the point (0,2) and applied it to the formula. It should look like 2= \(\frac{2}{5}\)(0)+b. Solve for b by multiplying 2/5 by zero and your left with 2=b. Plugin the missing varibles for the equation and it should come out to be y= \(\frac{2}{5}\)(x)+2.

A key requirement for the process of testing hypotheses in the scientific method is experimentation. A hypothesis is an idea or explanation for a phenomenon that is grounded in existing knowledge or observations, and the scientific method involves testing those hypotheses through experimentation.

The process of testing hypotheses requires the development of a testable hypothesis, the design of experiments to test the hypothesis, and the collection and analysis of data from those experiments to evaluate the hypothesis. The experiments must be designed carefully, with appropriate controls and variables to ensure that the results are reliable and valid. Scientists also need to communicate their findings to the scientific community, which involves publishing their results in scientific journals and presenting their work at conferences.

This helps to ensure that other scientists can replicate their experiments and validate their findings, which is a critical part of the scientific process. Ultimately, the process of testing hypotheses is essential for advancing scientific knowledge and understanding how the world works.

→ f(x) = 35

Now we have to,

→ Find the required value of x.

Forming the equation,

→ f(x) = f(x)

→ 2x + 3 = 35

Then the value of x will be,

→ 2x + 3 = 35

→ 2x = 35 - 3

→ 2x = 32

→ x = 32 ÷ 2

→ [ x = 16 ]

Hence, the value of x is 16.

The volume enclosed by the two curves when revolved about the x-axis is \(\(\frac{6\pi}{5} \ln 3 - \frac{3\pi}{2} \cdot 3^{\frac{4}{5}}\).\) To find the volume when the area enclosed by the graphs of \(\(y = x^2\)\)and \(\(y = \frac{3}{x^3}\)\) is revolved about the x-axis, we can use the method of cylindrical shells.

First, let's find the points of intersection between the two curves by setting them equal to each other:

\(\[x^2 = \frac{3}{x^3}\]\)

To simplify this equation, we can multiply both sides by \(\(x^3\)\):

\(\[x^5 = 3\]\)

Now, taking the fifth root of both sides:

\(\[x = \sqrt[5]{3}\]\)

So the two curves intersect at \(\(x = \sqrt[5]{3}\)\).

To calculate the volume area enclosed by the graphs of \(\(y = x^2\)\)and \(\(y = \frac{3}{x^3}\)\) is revolved about the x-axis, we need to integrate the circumference of each cylindrical shell multiplied by its height. The height of each shell is the difference in the y-values of the two curves, and the circumference is\(\(2\pi x\)\).

Let's integrate from \(\(x = 0\)\) to \(\(x = \sqrt[5]{3}\)\):

\(\[V = \int_0^{\sqrt[5]{3}} 2\pi x \left(\frac{3}{x^3} - x^2\right) \, dx\]\)

Simplifying this expression:

\(\[V = 2\pi \int_0^{\sqrt[5]{3}} \left(\frac{3}{x} - x^3\right) \, dx\]\)

Integrating each term separately:

\(\[V = 2\pi \left[3 \ln|x| - \frac{x^4}{4}\right]_0^{\sqrt[5]{3}}\]\)

Plugging in the limits of integration:

\(\[V = 2\pi \left[3 \ln|\sqrt[5]{3}| - \frac{\sqrt[5]{3}^4}{4}\right] - 2\pi \left[3 \ln|0| - \frac{0^4}{4}\right]\]\)

Since \(\(\ln|0|\)\)is undefined, the second term on the right side is zero:

\(\[V = 2\pi \left[3 \ln|\sqrt[5]{3}| - \frac{\sqrt[5]{3}^4}{4}\right]\]\)

Simplifying further:

\(\[V = 2\pi \left[3 \ln 3^{\frac{1}{5}} - \frac{3}{4} \cdot 3^{\frac{4}{5}}\right]\]\)

Using the properties of logarithms, we can simplify the first term:

\(\[V = 2\pi \left[3 \cdot \frac{1}{5} \ln 3 - \frac{3}{4} \cdot 3^{\frac{4}{5}}\right]\]\)

\(\[V = \frac{6\pi}{5} \ln 3 - \frac{3\pi}{2} \cdot 3^{\frac{4}{5}}\]\)

So the volume enclosed by the two curves when revolved about the x-axis is \(\(\frac{6\pi}{5} \ln 3 - \frac{3\pi}{2} \cdot 3^{\frac{4}{5}}\).\)

The length of the rectangle is 19 cm.

The formula for the area of a rectangle,

Area = Length x Width

Given that the area is 336 cm squared.

So, we can set up an equation,

⇒ 336 = (w + 5)w

where w represents the width of the rectangle.

Expanding this equation,

⇒ 336 = w² + 5w

Moving all terms to one side:

⇒ w² + 5w - 336 = 0

This is a quadratic equation that we can solve using the quadratic formula,

⇒ w = (-5 ± √(5² - 4(1)(-336))) / (2(1))

⇒ w = (-5 ± 23) / 2

We'll take the positive value,

⇒ w = 14

So, the width of the rectangle is 14 cm.

We also know that the length is 5 cm more than the width,

Therefore,

⇒ l = w + 5

⇒ l = 14 + 5

⇒ l = 19

Therefore, the length of the rectangle is 19 cm.

For more precise values, you can use statistical software or online calculators that provide a more extensive range of Z-values.

To find the Z-value for a given cumulative area using the normal distribution, you can use the Z-table or a statistical software. Since I can't provide an interactive table, I'll calculate the approximate Z-values using the Z-table for the provided cumulative areas:

a) A = 36.32%

To find the Z-value for a cumulative area of 36.32%, we need to find the value that corresponds to the area to the left of that Z-value. In other words, we're looking for the Z-value that has an area of 0.3632 to the left of it.

Approximate Z-value: 0.39

b) A = 10.75%

We're looking for the Z-value that has an area of 0.1075 to the left of it.

Approximate Z-value: -1.22

c) A = 90%

We're looking for the Z-value that has an area of 0.9 to the left of it.

Approximate Z-value: 1.28

d) A = 95%

We're looking for the Z-value that has an area of 0.95 to the left of it.

Approximate Z-value: 1.65

e) A = 5%

We're looking for the Z-value that has an area of 0.05 to the left of it.

Approximate Z-value: -1.65

f) A = 50%

The cumulative area of 50% is the median, and since the normal distribution is symmetric, the Z-value will be 0.

Please note that these values are approximate and calculated based on the Z-table. For more precise values, you can use statistical software or online calculators that provide a more extensive range of Z-values.

Solving a system of equations we can see that each pair of pants costs €82.94 and each coat costs €26.37

Let's define the variables:

x = cost of a pant

y = cost of a coat.

First, we know that:

3x + 2y = 245

And then there are discounts of 20% and 5%, and the cost of one of each is 100.75, then:

0.8x + 0.95y = 100.75

Then we have a system of equations:

3x + 2y = 245

0.8x + 0.95y = 100.75

We can isolate x on the second equation to get:

x = (100.75 - 0.96y)/0.8

x = 125.9 - 1.2y

Replace that in the other equation:

3*(125.9 - 1.2y) + 2y = 245

Solving for y:

3*125.9 - 3*1.2y + 2y = 245

y*(2 - 3*1.2) = 245 - 3*125.9

y = (245 - 3*125.9)/(2 - 3*1.2)

y = 82.94

Then the value of x is:

x = 125.9 - 1.2*82.94

We can use the formula of slope to find this answer.

The formula to find the slope is y2-y1/x2-x1.

The slope of line ST is 1/5: 2-0/5-(-5);   2/10=1/5

We know that for two lines to be perpendicular, they have to have reciprocal opposite slopes. For example, if the slope of a line is 2/1 then the slope of a line perpendicular is -1/2.

Therefore, the perpendicular line should have a slope of: 1/5------>-5

To find which answer it is, follow the steps below:

y2-y1/x2-x1

plugin known values

-2-y1/0-(-1)

-2-y1/1

In order to make this -5, y1 needs to be 3

-2-3/1=-5

3 is the correct value

The value of y is 3.

The slope of a line is a measure of its steepness.

Given:

Ware( -1, y)

Now,

slope of line ST =2-0/5-(-5)

slope=1/5

As two lines to be perpendicular, they have to have reciprocal opposite slopes.

Thus, the perpendicular line slope =-5

Now, y2-y1/x2-x1

= -2-y1/0-(-1)

= -2-y1/1
