Answer:
Section A
Volume of the cylindrical tool = 1413.72cm³
Section B
1) Curved Surface Area of the right circular cone = 251.33cm²
2) Volume of the right circular cone = 402.12cm³
Step-by-step explanation:
Section A
We are asked to find the volume of the cylindrical moulding tool.
Volume of a cylinder = πr²h
From the question, the cylindrical tool had a diameter of 10cm. This means the radius of the tool = Diameter ÷ 2 = 10cm ÷ 2 = 5cm
The height of the cylindrical tool = 18cm
Volume of the cylindrical tool = π × (5cm)² × 18cm
1413.7166941cm³
Approximately = 1413.72cm³
Section B
The height of a right circular cone is 6cm and its radius is 8cm.
1) Calculate its curved surface area.
The formula for the curved surface area of a right circular cone =
πrl
r = radius = 8cm
h = height = 6cm
l = √(r² +h²) = √(8² + 6²) = √100
l = 10cm
The curved surface area = πrl
= π × 8cm × 10cm
= 251.33cm²
2) Calculate the volume of the cone.
The formula for the volume of a cone=
1/3πr²h
radius (r) = 8cm
height (h) = 6cm
1/3πr²h
1/3 × π × 8² × 6
= 402.12cm³

A pair of shoes is ticketed $49.99 but marked 15% off. You had a coupon for an additional 10% off the sales price. You have to pay 6.75% sales tax on shoes. How much are you paying?
Answer:
$40.86
Step-by-step explanation:
just multiply 49.99 times 0.15 then multiply 49.99 times 0.10 then add those together to get 12.49 then multiply 49.99 times 0.0675 to get 3.37 then subtract 12.49 from 49.99 then add 3.37 to that so like
(49.99 - 12.49) + 3.37 = 40.86

270 is 75% of what number?
Answer:
360
Step-by-step explanation:
270 = 75% of x
270 = 0.75 × x
0.75x = 270
x = 270/0.75
x = 360
Answer: 360
Answer:
360
Step-by-step explanation:
We have, 75% × x = 270
or, 75/100 × x = 270
Multiplying both sides by 100 and dividing both sides by 75,
we have x = 270 × 100/75x = 360
If you are using a calculator, simply enter 270×100÷75, which will give you the answer.
ind the taylor series for f centered at 9 if f (n)(9) = (−1)nn! 8n(n 1) . [infinity] n = 0 what is the radius of convergence r of the taylor series? r =
The radius of convergence r is 1/8.
How to find the Taylor series?To find the Taylor series for f centered at 9, we can use the formula:
f(x) = ∑ (n=0 to infinity) [f^(n)(a)/(n!)] * (x-a)^n
where f^(n) denotes the nth derivative of f.
In this case, we are given that:
f^(n)(9) = (-1)^n * n! * 8^n * (n+1)
So, we can plug this into the formula for the Taylor series and get:
f(x) = ∑ (n=0 to infinity) [(-1)^n * 8^n * (n+1)/(n!)] * (x-9)^n
To find the radius of convergence r of the Taylor series, we can use the ratio test:
lim (n->infinity) |[(-1)^(n+1) * 8^(n+1) * (n+2)/((n+1)!)] / [(-1)^n * 8^n * (n+1)/(n!)]|
= lim (n->infinity) |(-1) * 8 * (n+2)/(n+1)|
= 8
Since the limit is equal to 8, which is a finite value, the series converges for values of x such that:
|x - 9| < 1/8
Therefore, the radius of convergence r is 1/8.

The depth of the water if the speed of the tsunami is 10 m/s is approximately 0.34 meters, or 34 centimeters, given by the equation d = s / (3v).
What is speed?Speed is the rate at which an object moves through a distance per unit of time. It is often expressed in meters per second (m/s) or kilometers per hour (km/h).
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It usually contains variables, constants, and mathematical operations, and can be solved to find the value of the variables.
According to the given information:
The equation relating the speed of a tsunami and the depth of the water is s = 3vd, where s is the speed of the wave (in m/s), v is the velocity of gravity (which is approximately 9.8 m/s²), and d is the depth of the water (in meters).
We can rearrange the equation to solve for d, which gives us:
d = s / (3v)
Plugging in the given values, we get:
d = 10 m/s / (3 × 9.8 m/s²)
Simplifying, we get:
d = 10 / 29.4
Therefore, the depth of the water is approximately 0.34 meters, or 34 centimeters.
So, if the speed of the tsunami is 10 m/s, the depth of the water is approximately 0.34 meters.

The half life of a radioactive substance is 1474 years. What is the annual decay rate? Express the percent to 4 significant digits. TIP Enter your answer as an integer or decimal number. Examples: 3, -4,5.5172 Enter DNE for Does Not Exist, oo for Infinity
This confirms that our answer of approximately 12.371% (or 0.12371 as a decimal) is correct.
To find the annual decay rate, we need to first convert the half-life of the substance into a decimal fraction. We can do this by dividing 1474 by 365 (the number of days in a year) to get 4.037. This means that the substance decays by 50% every 4.037 years.
To find the annual decay rate, we need to convert this decimal fraction into a percentage. We can do this by multiplying it by 100. So, the annual decay rate is approximately 12.371%, expressed to 4 significant digits.
To check our answer, we can use the formula:
A = A0 (1 - r)t
where A is the amount of substance remaining after time t, A0 is the initial amount of substance, and r is the annual decay rate (expressed as a decimal fraction). If we plug in t = 1 year (since we want to find the annual decay rate), A0 = 100 (assuming we start with 100 units of the substance), and A = 50 (since the substance decays by 50% in one half-life), we get:
50 = 100 (1 - r)1
Simplifying this equation, we get:
0.5 = 1 - r
r = 0.5

is (, ) = 3 − 32 an harmonic function? if yes, then find a corresponding analytic function ()
No, f(x, y) = 3x - 3y^2 is not a harmonic function.
A harmonic function is a twice continuously differentiable function f(x, y) that satisfies the Laplace equation:
∂²f/∂x² + ∂²f/∂y² = 0.
Let's check if f(x, y) = 3x - 3y^2 satisfies the Laplace equation:
∂²f/∂x² = ∂/∂x(3) = 0
∂²f/∂y² = ∂/∂y(-6y) = -6
∂²f/∂x² + ∂²f/∂y² = 0 + (-6) = -6 ≠ 0
Since the Laplace equation is not satisfied, f(x, y) = 3x - 3y^2 is not a harmonic function.
As for finding a corresponding analytic function, an analytic function is a function that is locally given by a convergent power series. Since f(x, y) is not a harmonic function, there is no corresponding analytic function.

Wilson viaja 53.7 millas en 1.6 horas. ¿Cuál es su velocidad promedio a la décima de milla por hora
más cercana?
Uniform line movement.
The uniform rectilinear movement is the movement that maintains a variation of the distance with respect to time always constant, since the acceleration is zero.
If we know that Wilson travels 53.7 miles in 1.6 hours, we determine the average speed from the following equation:
Speed = distance / time
Speed = 53.7 miles / 1.6 hours
Speed = 33.5625 miles/hour
V = 33.6 miles/hour
The average speed that Wilson travels is: V = 33.6 miles/hour.

teaspoon of tea per ounce of water plus a teaspoon for the pot. Use the inverse to find the number of ounces of water needed if 7 teaspoons of tea are used.
Using the given ratio, we can set up a proportion to find the number of ounces of water needed if 7 teaspoons of tea are used. Let x be the number of ounces of water needed:
1 teaspoon / 6 ounces = 7 teaspoons / x + 1 teaspoon
Multiplying both sides by the denominator on the right side gives:
x + 1 = 7 teaspoons * 6 ounces / 1 teaspoon
Simplifying the right side gives:
x + 1 = 42 ounces
Subtracting 1 from both sides gives:
x = 41 ounces
Therefore, 41 ounces of water are needed if 7 teaspoons of tea are used.
In summary, to find the number of ounces of water needed if 7 teaspoons of tea are used, we can use the inverse of the given ratio and set up a proportion to solve for x. The resulting proportion shows that 41 ounces of water are needed to make the tea.
