the diameter of the cylinder is 6 meters the height of the cylinder is 12 meters what is the volume

Answer:

24

Step-by-step explanation:

multiply 8 by 3

Since both sides are equal, we have shown that ∑(i=1 to 6) (dx_i + e) = d(∑\((i=1 to 6) x_i\)) + 6e. This represents the summation of the terms \((5x_3 + i)\) for i = 1 to 6.

To show that ∑(i=1 to 6) \((dx_i + e)\)= d(∑(i=1  \(x_i\)) + 6e, we can expand both sides and compare.

Left-hand side:

∑\((i=1 to 6) (dx_i + e) = (dx_1 + e) + (dx_2 + e) + (dx_3 + e) + (dx_4 + e) +\)(dx_5 + \(e) + (dx_6 + e)\)

                        = \(dx_1 + dx_2 + dx_3 + dx_4 + dx_5 + dx_6 + e + e + e + e\)+ e + e

                        = \((dx_1 + dx_2 + dx_3 + dx_4 + dx_5 + dx_6) + 6e\)

Right-hand side:

d(∑\((i=1 to 6) x_i)\)+ 6e = d\((x_1 + x_2 + x_3 + x_4 + x_5 + x_6)\)+ 6e

Now, let's compare the two sides:

Left-hand side: \((dx_1 + dx_2 + dx_3 + dx_4 + dx_5 + dx_6)\) + 6e

Right-hand side: d\((x_1 + x_2 + x_3 + x_4 + x_5 + x_6)\) + 6e

Since both sides are equal, we have shown that ∑\((i=1 to 6) (dx_i + e)\) = d(∑(i=1 to 6)\(x_i)\) + 6e.

To represent the equation\((5x_3 + 4) + (5x_3 + 5) + (5x_3 + 6) + (5x_3 +\)7) + \((5x_3 + 8) + (5x_3 + 9)\) using a Sigma operator notation, we can write it as:

∑\((i=1 to 6) (5x_3 + i)\)

This represents the summation of the terms \((5x_3 + i)\)for i = 1 to 6.

Step-by-step explanation:

The secant- secant angle TUV is half the measure of the intercepted arcs, that is

∠ TUV = \(\frac{1}{2}\) (SW - TV ) , substitute values

6x - 19 = \(\frac{1}{2}\) ( 12x - 5 - (2x + 7 ) ) ← multiply both sides by 2 to clear the fraction

12x - 38 = 12x - 5 - 2x - 7

12x - 38 = 10x - 12 ( subtract 10x from both sides )

2x - 38 = - 12 ( add 38 to both sides )

2x = 26 ( divide both sides by 2 )

x = 13

Then

SW = 12x - 5 = 12(13) - 5 = 156 - 5 = 151°

Using the information given in the problem to set up two equations and by solving them

25% of the number is 80.

An equation is a mathematical statement that expresses the equality of two expressions. It typically consists of two parts: the left-hand side and the right-hand side, separated by an equal sign (=). The left-hand side and right-hand side can contain variables, numbers, and mathematical operations such as addition, subtraction, multiplication, and division.

Let's call the number we're looking for "x". We can use the information given in the problem to set up two equations:

0.7x = 224 (equation 1)

0.95x = 304 (equation 2)

We want to find 25% of the same number, which can be written as 0.25x. We can solve for x using either equation 1 or equation 2 and then plug that value into 0.25x to find the answer.

Let's solve for x using equation 2:

0.95x = 304

x = 304/0.95

x = 320

Now that we know x is 320, we can find 25% of that number:

0.25x = 0.25(320) = 80

So 25% of the number we were looking for is 80.

Using concept of linear equations, Wesley earns $9 commission for selling a pair of shoes and $16 commission for selling a pair of boots.

What is a linear equation ?

A linear equation is an algebraic equation that describes a straight line in a two-dimensional plane. It involves variables that are raised to the first power, such as x, y, or z. A linear equation can be written in the form y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis). The slope represents the rate of change of the line, and the y-intercept represents the value of y when x is equal to zero.

Now,

Let's assume that Wesley earns a certain amount of commission for selling a pair of shoes and a certain amount for selling a pair of boots. Let's call the commission for selling a pair of shoes "S" and the commission for selling a pair of boots "B".

From the given information, we can set up the following system of equations:

9S + 10B = 241 (Yesterday's sales)

7S + 8B = 191 (Today's sales)

We can solve for S and B by using any method of solving linear equations, such as substitution or elimination. Here, we will use the elimination method:

Multiplying the first equation by 8 and the second equation by -10, we get:

72S + 80B = 1928

-70S - 80B = -1910

Adding the two equations, we get:

2S = 18

Therefore,

S = 9

Substituting this value of S into the first equation, we get:

9(9) + 10B = 241

81 + 10B = 241

10B = 160

B = 16

Therefore, Wesley earns $9 commission for selling a pair of shoes and $16 commission for selling a pair of boots.

The decision for this test at a .05 level of significance is not enough information to make a decision the correct answer is (d).

To make a decision for a hypothesis test, we compare the obtained test statistic (in this case, z = 1.80) with the critical value(s) based on the chosen level of significance (in this case, α = 0.05).

For a one-sample z test, if the obtained test statistic falls in the rejection region (i.e., beyond the critical value(s)), we reject the null hypothesis. Otherwise, if the obtained test statistic does not fall in the rejection region, we fail to reject the null hypothesis.

Without knowing the critical value(s) corresponding to a significance level of 0.05 and the directionality of the test (one-tailed or two-tailed), we cannot determine the decision for this test. Therefore, the correct answer is (d) There is not enough information to make a decision.

Answer: 300

Step-by-step explanation:

50 x 6 = 300

The final summary:

- The x-intercept with a negative value of x is (-1, 0).

- The x-intercept with a positive value of x is (5, 0).

- The y-intercept is (0, 5/6) or approximately (0, 0.833).

- The vertical asymptote is x = 6.

To find the intercepts and the vertical asymptote of the function\(\[ f(x) = \frac{x^2 - 4x - 5}{x - 6} \]\), we'll evaluate the function for specific values of x.

1. X-Intercepts:

The x-intercepts are the points where the graph of the function intersects the x-axis. To find them, we set f(x) = 0 and solve for x.

\(\[ \frac{x^2 - 4x - 5}{x - 6} = 0 \]\)

Since a fraction is equal to zero only when its numerator is zero, we can set the numerator equal to zero:

\(\[ x^2 - 4x - 5 = 0 \]\)

Now we can solve this quadratic equation by factoring or using the quadratic formula.

The factored form of the equation is:

\(\[ (x - 5)(x + 1) = 0 \]\)

Setting each factor equal to zero, we have:

x - 5 = 0  -->  x = 5

x + 1 = 0  -->  x = -1

So the x-intercepts are (5, 0) and (-1, 0).

2. Y-Intercept:

The y-intercept is the point where the graph of the function intersects the y-axis. To find it, we set x = 0 in the equation of the function.

\(\[ f(0) = \frac{0^2 - 4(0) - 5}{0 - 6} \]\)

\(\[ f(0) = \frac{-5}{-6} \]\)

\(\[ f(0) = \frac{5}{6} \]\)

So the y-intercept is (0, 5/6) or approximately (0, 0.833).

3. Vertical Asymptote:

The vertical asymptote is a vertical line that the graph of the function approaches but never crosses. In this case, the vertical asymptote occurs when the denominator of the function becomes zero.

Since the denominator is x - 6, we set it equal to zero and solve for x:

x - 6 = 0

x = 6

So the vertical asymptote is x = 6.

To summarize:

- The x-intercept with a negative value of x is (-1, 0).

- The x-intercept with a positive value of x is (5, 0).

- The y-intercept is (0, 5/6) or approximately (0, 0.833).

- The vertical asymptote is x = 6.

Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We can apply this theorem only in a right triangle.

Example:

The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.

Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm

We have,

We know that the pitch of a roof is defined as the ratio of the vertical rise to the horizontal distance, and is typically expressed as a fraction.

In this case, we are given that the roof is 13 feet long, with 5 feet of vertical rise and x feet of horizontal distance.

Therefore,

The pitch of the roof.

Pitch = vertical rise / horizontal distance

Pitch = 5 / x

We don't know the value of x, but we can use the fact that the roof is 13 feet long to solve it.

Since the horizontal distance and vertical rise form the legs of a right triangle, we can use the Pythagorean theorem to find the value of x.

x² + 5² = 13²

x² + 25 = 169

x² = 144

x = 12

Now,

Pitch = 5 / x

The real interest rate, using the approximation formula, is 0.01 or 1%. This means that after considering the expected inflation rate, the purchasing power of the money grows at a rate of 1%.

The real interest rate can be calculated using the approximation formula: real interest rate = nominal interest rate - expected inflation rate.

We have:

Nominal interest rate (i) = 0.04

Expected inflation rate (+1) = 0.03

Using the formula, we can substitute the given values:

Real interest rate = 0.04 - 0.03

Calculating the difference:

Real interest rate = 0.01

Therefore, the real interest rate, using the approximation formula, is 0.01 or 1%.

The nominal interest rate represents the rate at which money grows in a bank account or investment without considering inflation. On the other hand, the real interest rate takes into account the effects of inflation, allowing us to understand the true purchasing power of the money.

To calculate the real interest rate, we subtract the expected inflation rate from the nominal interest rate. In this case, the nominal interest rate is 0.04 (4%), and the expected inflation rate is 0.03 (3%).

Substituting the values into the formula, we get:

Real interest rate = 0.04 - 0.03

Real interest rate = 0.01 or 1%

Therefore, the real interest rate, in this scenario, is 0.01 or 1%. This means that after accounting for inflation, the purchasing power of the money grows at a rate of 1%.
