A cone with height h and radius r has volume V = 1/3πr^2h. If a certain cone with a height of 9 inches has volume V = 3πx^2 + 42πx + 147π, what is the cone’s radius r in terms of x?

Answers

Answer 1

The cone’s radius r in terms of x is x + 7

How to determine tthe cone’s radius r in terms of x?

From the question, we have the following parameters that can be used in our computation:

Volume, V = 3πx^2 + 42πx + 147π

Height, h = 9

The volume of a cone is

V = 1/3πr^2h

Substitute the known values in the above equation, so, we have the following representation

1/3πr^2 * 9 = 3πx^2 + 42πx + 147π

So, we have

3πr^2 = 3πx^2 + 42πx + 147π

Divide by 3π

r^2 = x^2 + 14x + 49

So, we have

r = √(x² + 14x + 49)

Evaluate

r = x + 7

Conan fills 5 tubes. 2 tennis balls are left. How many tubes does Conan need to put away all the tennis balls?

Answers

Therefore , the solution of the given problem of linear equation comes out to be conan needs one more tube to put away the remaining 2 tennis balls.

A linear equation is precisely what?

A straightforward regression curve is created using the equation y=mx+b. The y-intercept is m, and the slope is B. The previous line is usually referred to as a "math equation mixing numerous variables," even though y / y represent independent components. Only two variables are present in bivariate linear equations. There are no known solutions to application issues involving linear equations.

Here,

We know that Conan has 5 tubes, and that 2 tennis balls are left unfilled. This means that he has already filled up 5 - 1 = 4 tubes.

Each tube can hold a certain number of tennis balls, so we need to know how many tennis balls each tube can hold. Once we know that, we can figure out how many tubes are needed to hold the remaining 2 tennis balls.

Let's say each tube can hold n tennis balls. Then, the 4 filled tubes have a total capacity of 4n tennis balls. We also know that there are 2 tennis balls left unfilled. Therefore, we can set up the following equation:

4n + 2 = 5n

Simplifying this equation, we get:

2 = n

So each tube can hold 2 tennis balls. Therefore, Conan needs one more tube to put away the remaining 2 tennis balls.

Find an equation of the line that satisfies the given conditions.Through (−9, −11); perpendicular to the line passing through (−6, 1) and (−2, −1)

Answers

The equation of the line passing through (9,11) and perpendicular to the line passing through (6,1) and (2,1) is x = 6

Find the slope of the line passing through (6,1) and (2,1):

The slope of a line passing through two points (x1,y1) and (x2,y2) is given by:

slope = (y2 - y1) / (x2 - x1)

Substituting the given coordinates, we get:

slope = (1 - 1) / (2 - 6) = 0

Therefore, the slope of the line passing through (6,1) and (2,1) is 0.

Find the slope of the line perpendicular to the line passing through (6,1) and (2,1):

The slope of a line perpendicular to a line with slope m is given by:

perpendicular slope = -1/m

Substituting the slope of the line passing through (6,1) and (2,1), we get:

perpendicular slope = -1/0 (which is undefined)

This means that the line perpendicular to the line passing through (6,1) and (2,1) is a vertical line passing through the point (6,1) and (2,1).

Write the equation of the line passing through (9,11) and perpendicular to the line passing through (6,1) and (2,1):

Since the line passing through (6,1) and (2,1) is a horizontal line with equation y = 1, the line perpendicular to it is a vertical line passing through the point (6,1) and (2,1). The equation of a vertical line passing through a point (a,b) is given by:

To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it contains no "equal to" symbol. It will be regarded as a phrase.

Given that

x⁻¹/(x⁻¹ + y⁻¹) + x⁻¹/(x⁻¹ - y⁻¹) = 2y²/(y² - x²)

Now solve the left-side expression:

Answers

The value of the average normal distribution with a 95% degree of confidence is Z 1.96 as 95% of the area under the standard normal distribution curve should fall between -Z and Z, hence Z should be selected to reflect this.

In statistics, the standard normal distribution is a bell-shaped curve with a mean of 0 and a standard deviation of 1. The region beneath the curve between any two values represents the chance of seeing a value inside a given range.

At a 95% confidence level, the value of Z should be chosen so that 95% of the area under the standard normal distribution curve is between -Z and Z. Using a calculator or a generic table of the normal distribution, we may determine Z = 1.96 with a 95% confidence interval. In 95% of the situations, the values of the classic normal distribution lie between +/- 1.96 standard deviations from the mean.

She walks a distance of 8.85 meters from the flagpole, then places a mirror on flat on the ground, marked with an X at the center. She then steps 1.1 meters to the other side of the mirror, until she can see the top of the flagpole clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.15 meters. How tall is the flagpole? Round your answer to the nearest hundredth of a meter.

Answers

The height of the flagpole is approximately 10.05 meters.

What is Trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used to solve problems related to measurements of angles and distances.

We want to find the height h of the flagpole. We can use similar triangles to set up an equation involving the distances and heights in the diagram. In particular, we have two similar triangles: one formed by the mirror, Chloe's eyes, and the top of the flagpole, and another formed by the mirror, Chloe's feet, and the bottom of the flagpole. These triangles are similar because they have the same angles (due to the reflection in the mirror) and share one angle (the one formed by Chloe's eyes, the mirror, and the flagpole). Therefore, we can set up the following proportion:

h / (d + 1.15) = h / 1.1

where d is the distance from the mirror to the base of the flagpole. Solving for h, we get:

h = (1.1 / (d + 1.15)) * h

Cross-multiplying, we get:

h * (d + 1.15) = 1.1 * h

Simplifying, we get:

d = (1.1 / h) - 1.15

Now we can use the distance of 8.85 meters to set up another proportion involving the similar triangles:

h / d = (h + 1.15 + 1.1) / 8.85

where h + 1.15 + 1.1 is the total height of the triangle formed by the mirror, Chloe's eyes, and the top of the flagpole. Solving for h, we get:

h = (8.85 * d) / (d + 2.25)

Substituting the expression for d that we found earlier, we get:

h = (8.85 * ((1.1 / h) - 1.15)) / (((1.1 / h) - 1.15) + 2.25)

Simplifying and solving for h, we get:

h ≈ 10.05 meters

Therefore, the height of the flagpole is approximately 10.05 meters.

Step-by-step explanation:

A politician claims that he has 70% chance of being elected into oce. Arandom sample of 500 votes showed that he has 60% chance of being
elected into office. At 5% significance level, can we conclude that the
politician's claim is valid?

Answers

the sample data supports the claim that the politician's chance of being elected is less than 70%.

To test whether the politician's claim is valid, we can perform a hypothesis test using the null hypothesis that the true probability of the politician being elected is 0.7 and the alternative hypothesis that the true probability is less than 0.7.

Let p be the true probability of the politician being elected. We have:

Null hypothesis: H 0 : p = 0.7

Alternative hypothesis: H a : p < 0.7 (one-tailed test with alpha = 0.05)

We can use the sample proportion, denoted by p, to estimate the true proportion p. The test statistic for testing the above hypotheses is given by:

z = (p - p) / √(p×(1-p)/n)

where n = 500 is the sample size. Under the null hypothesis, the test statistic follows a standard normal distribution. Using the given sample proportion p = 0.6, we can compute the test statistic as follows:

z = (0.6 - 0.7) / √(0.7×(1-0.7)/500) = -3.05

The corresponding p-value for this test statistic is P(Z < -3.05) = 0.0012 (using a standard normal distribution table or calculator).

Since the p-value (0.0012) is less than the significance level (0.05), we reject the null hypothesis and conclude that there is sufficient evidence to suggest that the true probability of the politician being elected is less than 0.7. In other words, the sample data supports the claim that the politician's chance of being elected is less than 70%.

πr_c^2h_c / 4 = πr_p^2h_p / 5

h_c / h_p = (r_p / r_c)^2 * (5 / 4)

Answers

The expression below are correct:

πr_c^2h_c / 4 = πr_p^2h_p / 5

h_c / h_p = (r_p / r_c)^2 * (5 / 4)

How can we prove this assertion?

To prove that the equation

πr_c^2h_c / 4 = πr_p^2h_p / 5

and

h_c / h_p = (r_p / r_c)^2 * (5 / 4)

are correct, we can use some algebraic manipulation and the properties of ratios.

Starting with the first equation, we can simplify it as follows:

πr_c^2h_c / 4 = πr_p^2h_p / 5

5πr_c^2h_c = 4πr_p^2h_p (multiply both sides by 20 to get rid of fractions)

5r_c^2h_c = 4r_p^2h_p (cancel out π on both sides)

Next, we can rearrange the second equation to solve for h_c:

h_c / h_p = (r_p / r_c)^2 * (5 / 4)

h_c = h_p * (r_p / r_c)^2 * (5 / 4) (multiply both sides by h_p)

Now we can substitute this expression for h_c into the simplified version of the first equation:

5r_c^2h_c = 4r_p^2h_p

5r_c^2(h_p * (r_p / r_c)^2 * (5 / 4)) = 4r_p^2h_p (substitute h_c)

5r_c^2r_p^2(5/4) = 4r_p^2h_p (simplify)

5r_c^2 = (16/25)h_p (divide both sides by 4r_p^2)

Finally, we can substitute this expression for h_p into the earlier expression we found for h_c:

h_c = h_p * (r_p / r_c)^2 * (5 / 4)

h_c = (5/16)r_c^2 (substitute for h_p)

h_c / r_c^2 = 5/16

This means that the ratio of the height to the radius squared for cylinder c is 5/16, which is a constant value. We can also rearrange the simplified first equation to solve for h_p in terms of r_c and r_p:

5r_c^2h_c = 4r_p^2h_p

h_p = (5/4)h_c(r_c/r_p)^2 (divide both sides by 4r_p^2 and multiply by 5/4)

Substituting this expression for h_p into the second equation, we get:

h_c / h_p = (r_p / r_c)^2 * (5 / 4)

h_c / ((5/4)h_c(r_c/r_p)^2) = (r_p / r_c)^2 * (5 / 4) (substitute for h_p)

1 / ((5/4)(r_c/r_p)^2) = (r_p / r_c)^2 * (5 / 4) (simplify)

Now we can simplify this expression using the fact that (r_p / r_c)^2 = 1 / (r_c / r_p)^2:

1 / ((5/4)(r_c/r_p)^2) = (1 / (r_c/r_p)^2) * (5/4)

1 / (5/4) = (r_c/r_p)^4 * (5/4)

4/5 = (r_c/r_p)^4

(r_c/r_p)^2 = √(2/√5) or -(√2/√(√5))

How to calculate value of g ?

Answers

To calculate the value of g we have to multiply the G( universal gravitational constant) and M( mass of body) divide by R square.

Earth's acceleration caused by gravity, or the magnitude of g, is 9.8 m/s2. According to this, an item falling freely on Earth would accelerate by 9.8 metres per second. The gravity of the Earth is to blame for this acceleration.

The acceleration due to gravity formula is given by

[tex]g = \frac{GM}{R^2}[/tex]

Where,

G is the universal gravitational constant, G = 6.674×10-11m3kg-1s-2.

M is the mass of the massive body measured using kg.

Given.. a square proof it’s a rhombus.

Answers

Yes, in solid geometry a square is a rhombus. A rhombus has all four sides equal just like a square for why it is also known as a titled square.

Define a rhombus.

A rhombus can be thought of as a special parallelogram since it is a quadrilateral with two pairs of parallel sides. Similar to a square, a rhombus likewise has equal sides on each of its four sides. As a result, it's frequently referred to as a tilted square.

According to definition, a square is a regular quadrilateral with four equal sides and four equal 90-degree angles.

Rhombus also has four equal sides.

After simplifying and finding x, we obtain: (x - 4)([tex]x^2[/tex] - 4x + 32) = 0

[tex]x^3[/tex] - [tex]8x^2[/tex] - 64x + 128 = 0

There are no actual roots for the quadratic factor, hence we have the:

x = 4

Line BC, therefore, has a length of 4.

Describe Inequality.

In mathematics, an inequality is a statement that two values are not equal. Instead, one value is either greater than or less than the other value. Inequalities are represented by symbols such as < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to).

For example, the inequality 5 < 8 means that 5 is less than 8, while the inequality x + 3 > 7 means that the sum of x and 3 is greater than 7.

Inequalities can be graphed on a number line, which is a horizontal line that represents the set of real numbers. To graph an inequality on a number line, you can draw a closed or open circle at the value of the variable that satisfies the inequality, and shade the region to the left or right of the circle, depending on the direction of the inequality.

For example, to graph the inequality x < 3, you would draw an open circle at 3 on the number line, and shade the region to the left of the circle, because x is less than 3. Similarly, to graph the inequality y ≥ -2, you would draw a closed circle at -2 on the number line, and shade the region to the right of the circle, because y is greater than or equal to -2.

Graphing inequalities on a number line is a useful tool for solving problems and visualizing the solutions to inequalities in one variable.

Let BC = x.

Using the Triangle Inequality on triangle ABD, we have:

AB + BD > AD

6 + x > 4 + 2

x > -4

Using the Triangle Inequality on triangle BDC, we have:

BC + CD > BD

x + 2 > 4

x > 2

Therefore, we have:

2 < x < 6

Now, we can use the Law of Cosines on triangle BDC:

BD² = BC² + CD² - 2BC·CD·cos(BDC)

Substituting known values and solving for x, we have:

4 = x² + 4 - 8x·cos(BDC)

x² - 8x·cos(BDC) + 0 = 0

x(x - 8·cos(BDC)) = 0

Since x cannot be zero, we have:

x - 8·cos(BDC) = 0

cos(BDC) = x/8

Using the Law of Cosines on triangle ACE:

AC² = AE² + CE² - 2AE·CE·cos(ACE)

Substituting known values and simplifying, we have:

(6 + x)² = 4² + 2² - 2·4·2·cos(ACE)

36 + 12x + x² = 20 - 16cos(ACE)

cos(ACE) = (12x + x² - 16)/(-16)

Since cos(BDC) = cos(ACE), we have:

x/8 = (12x + x² - 16)/(-16)

Simplifying and solving for x, we have:

8x² + 64x - x³ - 128 = 0

x³ - 8x² - 64x + 128 = 0

(x - 4)(x² - 4x + 32) = 0

The quadratic factor has no real roots, so we have:

x = 4

Therefore, the length of line BC is 4.

Eight upright domino's of increasing heights are lined up to be knocked down. The dominos are numbered 0 to 7. The smallest domino, #0 is 5.00 cm tall and will be toppled by a person to start the chain reaction. Each subsequent domino is 13% taller than the one before. What is the height of domino number 7?

Answers

The required height of domino number 7 is 11.76 cm (rounded to two decimal places).

What is arithmetic progression?

Arithmetic progression is the series of numbers that have common differences between adjacent values.

Here,
Since each subsequent domino is 13% taller than the one before, we can find the height of each domino by multiplying the height of the previous domino by 1.13.

Starting with the height of the smallest domino, we can calculate the height of each subsequent domino using this rule:

Height of domino n = Height of domino (n-1) × 1.13

Using this formula, we can find the height of each domino:

Height of domino 1 = 5.00 cm × 1.13 = 5.65 cm

Height of domino 2 = 5.65 cm × 1.13 = 6.38 cm

Height of domino 3 = 6.38 cm × 1.13 = 7.21 cm

Height of domino 4 = 7.21 cm × 1.13 = 8.16 cm

Height of domino 5 = 8.16 cm × 1.13 = 9.22 cm

Height of domino 6 = 9.22 cm × 1.13 = 10.41 cm

Height of domino 7 = 10.41 cm × 1.13 = 11.76 cm

Therefore, the height of domino number 7 is 11.76 cm (rounded to two decimal places).
