Answer:

[tex]r = \sqrt{\frac{24}{h}}[/tex] inches

Step-by-step explanation:

Volume of a cone = [tex]\frac{1}{3} \pi r^{3}h[/tex]

 where: r = radius of cone

             h = perpendicular height of the cone

Provided volume of cone = 8π cubic inches

[tex]8\pi = \frac{1}{3}\pi r^{2} h[/tex]

Cross multiplication is applied and 'r' is isolated:

[tex]3(8\pi ) = \pi r^{2} h[/tex]

[tex]24\pi =\pi r^{2} h[/tex]

[tex]r^{2} h = \frac{24\pi}{\pi}[/tex]

[tex]\pi[/tex] in the numerator and denominator cancel each other out completely:

[tex]r^{2} h = 24[/tex]

[tex]r^{2} = \frac{24}{h}[/tex]

Taking the square root on both sides of the equation in order to get rid of the square:

[tex]r = \sqrt{\frac{24}{h}}[/tex] inches

The volume of the solid generated by revolving the region bounded by the given lines and curves about the x-axis is 8π/3 cubic units.

The volume of the solid generated by revolving this region about the x-axis can be found using the method of cylindrical shells. The volume is given by:

V = ∫[0, 2] 2πx(2 - 2√x) dx

Evaluating the definite integral:

V = π ∫[0, 2] (4x - 4x^(3/2)) dx

= π [2x^2 - 4/3 x^(3/2) ] |_0^2

= π [4 - (4/3)(2^(3/2))]

= 8π/3.

Therefore, the volume of the solid generated by revolving the region bounded by the lines y = 2 and y = 2√x and the x-axis about the x-axis is 8π/3 cubic units.

There are 0.0496 Gg/hr in 8.34 x 10^6 tons/week

To convert from tons/week to Gg/hr:

you need to divide the number of tons by the number of hours in a week and then multiply by 1 Gg/ton.

There are 168 hours in a week, so:

8.34 x 10^6 ton/wk / 168 hrs/week = 49642.85 ton/hr

And 1 Gg = 1,000,000 ton, so:

49642.85 ton/hr * 1 Gg/1,000,000 ton = 0.0496 Gg/hr

So, 8.34 x 10^6 tons/week is equivalent to 0.0496 Gg/hr.

The period of time during which the projectile is at least 240 feet above the ground is 3 seconds <= t <= 5 seconds.

What is time of projectile motion?

Vertical motion totally determines the time for projectile motion.

The height of the projectile above the ground after t seconds is given by s = -16t^2 + 128t. To find the period of time during which the projectile is at least 240 feet above the ground, we need to find the values of t for which s >= 240.

Solving for t:

-16t^2 + 128t >= 240

-16t^2 + 128t - 240 >= 0

t^2 - 8t + 15 >= 0

(t - 5)(t - 3) >= 0

So t must be between 3 and 5 seconds, inclusive.

Therefore, the period of time during which the projectile is at least 240 feet above the ground is 3 seconds <= t <= 5 seconds.

Each side of the given figure measures 2yd and the area of the polygon is A = 8 + 8√2 square units, and apothem is 8 + 8√2 units.

A polygon is a closed, two-dimensional (2-D) figure formed of segments of straight lines. The octagon is an 8-sided polygon in geometry. An octagon is referred to as a regular octagon if all of its sides and angles have equal lengths. In other words, an ordinary octagon has congruent sides. In a standard octagon, the inside angle is 135 degrees, and the outer angle is 45 degrees. A preset set of formulas known as the "octagon formula" can be used to calculate the area and perimeter of a regular octagon.

Given that the perimeter of the octagon is 16yd.

The perimeter is the sum of all the segments or boundaries. So, the perimeter of the octagon is:

P = 8s

16 = 8s

s= 2yd.

The area of a regular octagon is given as:

A = 2a²(1 + √2)

A = 2(2)²(1 + √2)

A = 8 + 8√2

The apothem is given by:

A = 1/2 (s)(a)

8 + 8√2 = 1/2 (2)(a)

a = 8 + 8√2

Hence, each side of the given figure measures 2yd and the area of the polygon is A = 8 + 8√2 square units, and apothem is 8 + 8√2 units.

Answer:

i- 72000 * π radians per hour,  ii- 65,940 miles per hour.

Step-by-step explanation:

(i) To find the car's angular speed in radians per hour, we need to find the number of radians the wheel rotates in one revolution, then multiply that by the number of revolutions per second. The number of radians in one revolution is equal to the circumference of the wheel divided by the wheel's radius. The wheel's circumference is given by 2 * π * r, where r is the wheel's radius (18 inches / 2 = 9 inches). Then, the number of radians per revolution is:

2 * π * r / r = 2 * π

So, the number of radians per second is:

2 * π * 10 revolutions per second = 20 * π radians per second

Finally, to convert radians per second to radians per hour, we multiply by 3600 (the number of seconds in an hour):

20 * π * 3600 seconds/hour = 72000 * π radians per hour

(ii) To find the car's linear speed in miles per hour, we need to multiply the wheel's circumference by the number of revolutions per hour. The wheel's circumference is given by 2 * π * r, so the linear speed is:

2 * π * r * 10 revolutions per second * 3600 seconds/hour = 18 * π * 10 * 3600 miles per hour

The answer is approximately equal to 65,940 miles per hour.

The percentage of increase is given by the equation A = 85 %

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the percentage change be represented as P

Now , the equation will be

The initial value be represented as A = 40

The final or increased value be B = 74

So , the percentage change P = [ ( | A - B | ) / A ] x 100

Substituting the values in the equation , we get

The percentage change P = [ ( 34 ) / 40 ] x 100

The percentage change P = 0.85 x 100

The percentage change P = 85 %

Step-by-step explanation:

To find the equation of a line that is parallel to another line, we can use the same slope for both lines. The slope of the line with the equation -14x + 3y = -4 can be found by rearranging the equation into slope-intercept form:

y = -14/3x - 4/3

The slope of this line is -14/3.

To find the equation of a line that passes through the point (2,-6) with the same slope, we can use the point-slope form of a line:

y - y1 = m(x - x1)

Where:

m is the slope of the line

(x1, y1) is a point on the line

Plugging in the values from the given information:

m = -14/3

x1 = 2

y1 = -6

y - (-6) = -14/3 (x - 2)

y + 6 = -14/3x + 14

So the equation of the line through the point (2,-6) that is parallel to the line with the equation -14x + 3y = -4 is:

y + 6 = -14/3x + 14.

The ratio of ozone used to the total amount of water treated per day can be calculated as follows:

Ozone used = 25,000 mg

Amount of water treated = 16,000,000 liters = 16,000,000 x 1000 ml = 16,000,000 x 1000 x 1000 mg = 16,000,000,000,000 mg

Ratio of ozone used to water treated = 25,000 / 16,000,000,000,000 = 1.5625 x 10^-11

So, the ratio of ozone used to the total amount of water treated per day is approximately 1.5625 x 10^-11.

[tex]15.625*10^{-4}[/tex] miligrams of ozone / liter of water.

[tex]\frac{25,000}{16,000,000} =\\ \\\frac{0.0015625}{1} =\\ \\\frac{15.625*10^{-4} }{1}[/tex]

At the end of two years if prices increase 5 percent the family needs to spend a total of $56227.50 on their annual living expenses.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Given that, the family spends $51,000 a year.

The first increase of 5% is given as:

A = (51000) (1 + 5/100)

A = 51000 (105/ 100) = 53550

For the second year increase:

A = 53550 (105 / 100) = 56227.50
