Answer:

19

Step-by-step explanation:

r = 32.5 cm

C = 2πr = 2(3.14159)(32.5 cm) = 204.20 cm

40 m = 40 m × (100 cm)/m = 4000 cm

4000 cm / 204.2 cm = 19.588

Answer: 19

The percent decrease is found by using the formula (original price - new price)/(original price). The percent decrease is then (2.49 - 1.99)/2.49 = 0.20 = 20%. A percent increase is found by using the formula (new price - original price)/(original price). The percent increase is then (2.49 - 1.99)/1.99 = 0.25 = 25%. The percents of change are not the same. The percent increase is greater.

Answer:

2.49-1.99= 0.5

0.5 divided by2.49 times 100 is about 20% decrease

1.99-2.49+0.5 also so it is also a 25 percent increase

section 2 has dimensions:

length = 46 - 21 = 25

width = 30 - 14 = 16

Area = 25 * 16 = 400

Therefore , the solution of the given problem of percentage comes out to be 38 years old is the median age.

In statistics, a "a%" is a figure or statistic that is expressed as a percentage of 100. The words "pct," "pct," but instead "pc" are also not frequently used. However, the sign "%" is frequently used to represent it. The percentage sum is flat; there are no dimensions. Percentages are truly integers because their numerator almost always equals 100. Either the % symbol (%) or the additional term "fraction" must come before a number to denote that it is a percentage.

Here,

The following algorithm must be used to determine the mean age:

=> mean = (all years added together) / (total number of persons)

The representative age for each age group is the age that falls in the middle of the range. With this approach, we can determine the total age as follows:

=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)

=> 162 + 644 + 924 + 2970 + 4636 + 2688 + 1152 + 1520 + 272.25

=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)

According to the information provided, there are 460 people in total.

=> mean = 17745.25 / 460

=> mean = 17745.25 / 460

As a result, the average lifespan is roughly 38.552 years.

The age category in this instance with the highest frequency has a midpoint of 38 and a frequency of 122. As a result, 38 years old is the median age.

Answer: Neither They were the same shade of Grey.

Step-by-step explanation:

it’s the right answer trust me

Color would be the same for both statue and stone buildings.

Let's, consider paint black as = x

and paint white as = y

If both the paints are mixed then paint z which is grey is formed.

Represented as,

x(black) + y(white) = z(grey)

Whereas, for the stone building double the amount of black and white colors are being used,

2x + 2y = 2z, coating of grey color would be also double.

Canceling 2 from both sides,

x + y = z

x(black) + y(white) = z(grey)

Therefore color would be the same for both statue and stone buildings.

Answer:

He should have said that his small brother had 100 small building bricks, but lost 5 in total now.

The Volume generated when the region between the curves is rotated around the y - axis is 1216500335.46

Volume of the curves:

The volume of the solid formed by revolving the region bounded by the curve x = f(y) and the y-axis between y = c and y = d about the y-axis is given by

V = π ∫dc [f(y)]2dy.

The cross-section perpendicular to the axis of revolution has the form of a disk of radius R = f(y).

Given,

y = x³

Here we have to find the volume along to the y axis.

With limit as y = 0 and y = 27.

When we apply the values it can be written as,

=>\(V=\pi \int\limits^0_{27} {(x^3)^2} \, dx\)

\(\implies V=\pi \int\limits^0_{27} {(x^6)} \, dx\)

Apply the limits then we get,

\(\implies V = \pi [0^6 - (27)^6]\)

=> V = π [0 - 387420489]

=> V =   π x 387420489

=> V = 1216500335.46

The parametric equation for the tangent line to the curve is x = 1 - t, y = t, z = 1 - t.

For this question,

The curve is given as

x(t)=e^-t cos(t),

y(t) =e^-t sin(t),

z(t)=e^-t

The point is at (1,0,1)

The vector equation for the curve is

r(t) = { x(t), y(t), z(t) }

Differentiate r(t) with respect to t,

x'(t) = -e^-t cos(t) + e^-t (-sin(t))

⇒ x'(t) = -e^-t cos(t) - e^-t sin(t)

⇒ x'(t) = -e^-t (cos(t) + sin(t))

y'(t) = - e^-t sin(t) + e^-t cos(t)

⇒ y'(t) = e^-t ((cos(t) - sin(t))

z'(t) = -e^-t

Then, r'(t) = { -e^-t (cos(t) + sin(t)), e^-t ((cos(t) - sin(t)), -e^-t }

The parameter value corresponding to (1,0,1) is t = 0. Putting in t=0 into r'(t) to solve for r'(t), we get

⇒  r'(t) = { -e^-0 (cos(0) + sin(0)), e^-0 ((cos(0) - sin(0)), -e^-0 }

⇒  r'(t) = { -1(1+0), 1(1-0), -1 }

⇒  r'(t) = { -1, 1, -1 }

The parametric equation for line through the point (x₀, y₀, z₀) and parallel to the direction vector <a, b, c > are

x = x₀+at

y = y₀+bt

z = z₀+ct

Now substituting the (x₀, y₀, z₀) as (1,0,1) and <a, b, c > into x, y and z, respectively to solve for the parametric equation of the tangent line to the curve, we get

x = 1 + (-1)t

⇒ x = 1 - t

y = 0 + (1)t

⇒ y = t

z = 1 + (-1)t

⇒ z = 1 - t

Hence we can conclude that the parametric equation for the tangent line to the curve is x = 1 - t, y = t, z = 1 - t.

We can use the method of Lagrange multipliers to find the extrema of f(x, y) subject to the constraint x^2 + y^2 = 1. Let λ be the Lagrange multiplier.

We set up the following system of equations:

∇f(x, y) = λ∇g(x, y)

g(x, y) = x^2 + y^2 - 1

where ∇ is the gradient operator, and g(x, y) is the constraint function.

Taking the partial derivatives of f(x, y), we get:

∂f/∂x = (-1/4)e^(-xy/4)y

∂f/∂y = (-1/4)e^(-xy/4)x

Taking the partial derivatives of g(x, y), we get:

∂g/∂x = 2x

∂g/∂y = 2y

Setting up the system of equations, we get:

(-1/4)e^(-xy/4)y = 2λx

(-1/4)e^(-xy/4)x = 2λy

x^2 + y^2 - 1 = 0

We can solve for x and y from the first two equations:

x = (-1/2λ)e^(-xy/4)y

y = (-1/2λ)e^(-xy/4)x

Substituting these into the equation for g(x, y), we get:

(-1/4λ^2)e^(-xy/2)(x^2 + y^2) + 1 = 0

Substituting x^2 + y^2 = 1, we get:

(-1/4λ^2)e^(-xy/2) + 1 = 0

e^(-xy/2) = 4λ^2

Substituting this into the equations for x and y, we get:

x = (-1/2λ)(4λ^2)y = -2λy

y = (-1/2λ)(4λ^2)x = -2λx

Solving for λ, we get:

λ = ±1/2

Substituting λ = 1/2, we get:

x = -y

x^2 + y^2 = 1

Solving for x and y, we get:

x = -1/√2

y = 1/√2

Substituting λ = -1/2, we get:

x = y

x^2 + y^2 = 1

Solving for x and y, we get:

x = 1/√2

y = 1/√2

Therefore, the extrema of f(x, y) subject to the constraint x^2 + y^2 = 1 are:

f(-1/√2, 1/√2) = e^(1/8)

f(1/√2, 1/√2) = e^(1/8)

Both of these are local maxima of f(x, y) subject to the constraint x^2 + y^2 = 1.

7x/7 = -21/7 (Divided 7 on both sides by using the division property of equality)

x = -3 (Simplified)

Therefore, x = -3.

\(\boxed {x = -33}\)

Step-by-step explanation:

Solve for the value of \(x\):

\(6 + \frac{x}{3} = -5\)

-Multiply both sides by \(3\):

\(3 \times 6 + \frac{x}{3} = -5 \times 3\)

\(18 + x = -15\)

-Subtract \(18\) to both sides:

\(18 - 18 + x = -15 - 18\)

\(\boxed {x = -33}\)

Therefore, the value of \(x\) is \(-33\).
