There are some bacteria in a dish. Every hour, each bacterium splits into 3 bacteria. Hence, in total after 3 hours, we have 27 bacteria.

Bacteria are ubiquitous, largely free-living creatures that frequently only have one biological cell. They make up a significant portion of the prokaryotic microbial kingdom. Bacteria, which tend to be a few micrometres long and were among the initial organisms that appeared on Earth, are found in the majority of its habitats.

n = the number of bacteria at a given hour

at zero hour=1 bacteria.

1 bacteria after an hour is split in to 3 bacteria.

n(1)  = 3

n(2)  = 3 x 3  = 9 bacteria

n(3)  = 9 x 3  = 27 bacteria

Hence, in total after 3 hours, we have 27 bacteria

A 17% reduction means that the dress cost 83% (100 - 17) of the original amount.

\(\large \fbox{\begin{minipage}{8.1 cm}83\% of the original price = \£45.65\\\\$\Rightarrow$1\% of the original price = $\frac{45.65}{83}$\\\\$\Rightarrow$1\% of the original price = 0.55\\\\$\Rightarrow$100\% of the original price = 0.55 \times 100\\\\$\Rightarrow$100\% \text{ of the original price = \£55}\end{minipage}}\)

The probability that x is less than 5 = 0.45

Discrete probability distribution:

It is a type of probability distribution that displays all the possible values of a discrete random variable accompanying the affiliated probabilities. We can also say that a discrete probability distribution provides the chance of occurrence of every possible value of a discrete random variable.

The value of the integral ∫∫∫E √(x² + y²) dv in cylindrical coordinates is 5.

To evaluate the given integral, we can use cylindrical coordinates, which are defined by the radial distance ρ, the azimuthal angle φ, and the height z.

The region E is described as the space inside the cylinder (x - 1)² + y² = 1 and between the planes z = -1 and z = 1. In cylindrical coordinates, the equation of the cylinder becomes ρ² = 1, which represents a cylinder of radius 1 centered along the z-axis. The limits for the variables are ρ = 0 to ρ = 1, φ = 0 to φ = 2π, and z = -1 to z = 1.

The integrand is √(x² + y²), which in cylindrical coordinates becomes ρ. Therefore, the integral can be rewritten as ∫∫∫E ρ dv.

Using cylindrical coordinates, the volume element dv is ρ dρ dφ dz.

Integrating with respect to ρ, φ, and z over their respective limits, we get:

∫∫∫E ρ dv = ∫[φ=0 to 2π] ∫[ρ=0 to 1] ∫[z=-1 to 1] ρ ρ dρ dφ dz.

Integrating ρ with respect to ρ gives (ρ²/2), and evaluating it from 0 to 1 gives (1/2 - 0) = 1/2.

Integrating the remaining terms with respect to their respective variables gives 2π for φ and 2 for z.

Therefore, the final result of the integral is (1/2) * 2π * 2 = 5.

Hence, the value of the integral ∫∫∫E √(x² + y²) dv in cylindrical coordinates is 5.

Answer:

Step-by-step explanation:

x² − 1 is not a factor of P(x) = 2x⁴ + 7.

Factor Theorem:

The point of the factor theorem is the inverse of the remainder theorem. If we divide a polynomial by x = a globally and the remainder is zero, then not only is x = a a root of the polynomial (courtesy of the Remainder Theorem), but x − a is also a factor of the polynomial (Factor Theorem courtesy of ).

According to the factor theorem, (y – a) can be considered as a factor of a polynomial g(y) of degree n ≥ 1 if and only if g(a) = 0. where a is any real number. The factor set formula is g(y) = (y – a) q(y). It is important to note that all of the following apply to any polynomial g(y).

According to the Question:

P(x) = 2x⁴+ 7 > 0 for any real x, so it has not real zeros. Because P(x) has not factor x² - 1 = (x + 1)(x -1) what has real zeros 1 and - 1.

Given:

On the first day, she drove 650 miles in 10 hours.

On the second day, she got a later start and drove 540 miles in 8 hours.

To find:

Difference between average speed of second day and first day.

Solution:

We know that,

\(Speed=\dfrac{Distance}{Time}\)

On the first day, she drove 650 miles in 10 hours.  So, the average speed is

\(Speed=\dfrac{650}{10}\)

\(Speed=65\)

So, the average speed on first day is 65 miles per hour.

On the second day, she got a later start and drove 540 miles in 8 hours.

\(Speed=\dfrac{540}{8}\)

\(Speed=67.5\)

So, the average speed on second day is 67.5 miles per hour.

Difference between average speed is

\(67.5-65=2.5\)

Therefore, the average speed on the second day is 2.5 miles per hour is faster than first day.

Answer:

(8x+4) ( x-5)

Step-by-step explanation:

Well we can't factor out the 8 and solve because if we do the -20 and -36 will be decimals.

So we do this

8 * -20 = -160

We need to find 2 number that multiplies  to -160 and adds to -36

-40 and 4 fit this category

they add to -36 and multiply to -160

Now we write the equation as

8x(x-5) + 4(x-5)

Answer:

Step-by-step explanation:

See attached worksheet.

∂g/∂u is equal to 21u⁵cos⁴(v)sin⁴(v)(cos(v) + u³cos⁴(v)sin²(v)sin(v)).

To find the indicated derivative, we need to use the chain rule. Let's differentiate step by step:

Given:

g(u, v) = f(x(u, v), y(u, v))

f(x, y) = 7x³y³

x(u, v) = ucos(v)

y(u, v) = usin(v)

To find ∂g/∂u, we differentiate g(u, v) with respect to u while treating v as a constant:

∂g/∂u = (∂f/∂x) * (∂x/∂u) + (∂f/∂y) * (∂y/∂u)

To find ∂f/∂x, we differentiate f(x, y) with respect to x:

∂f/∂x = 21x²y³

To find ∂x/∂u, we differentiate x(u, v) with respect to u:

∂x/∂u = cos(v)

To find ∂f/∂y, we differentiate f(x, y) with respect to y:

∂f/∂y = 21x³y²

To find ∂y/∂u, we differentiate y(u, v) with respect to u:

∂y/∂u = sin(v)

Now, we can substitute these partial derivatives into the equation for ∂g/∂u:

∂g/∂u = (21x²y³) * (cos(v)) + (21x³y²) * (sin(v))

To find the simplified form, we substitute the given values of x(u, v) and y(u, v) into the equation:

x(u, v) = ucos(v) = u * cos(v)

y(u, v) = usin(v) = u * sin(v)

∂g/∂u = (21(u * cos(v))²(u * sin(v))³) * (cos(v)) + (21(u * cos(v))³(u * sin(v))²) * (sin(v))

Simplifying further, we get:

∂g/∂u = 21u⁵cos⁴(v)sin⁴(v)(cos(v) + u³cos⁴(v)sin²(v)sin(v))

The term "directrix" refers to the circumference of a cone's base, and "generatrix" or "generating line" refers to each line segment between the directrix and apex.

(For a relationship between the directrix of a conic section and the name "directrix" in this sense, see Dandelin spheres.

A cone's volume is equal to one-third of the sum of the base's area and the cone's height. Cubic units are used to measure volume.

A cone's radius affects how tall it is. A cone with a radius of 1 /2 has a height of 0.26. Volume is the amount of space that is occupied by a three-dimensional object.

A cone's volume (V) is determined by:

V = (1/3)πr²h

Where r is the radius and h is the height.

For a radius of 1/2:

=(1/3)π*(1/2)²*h

=(1/3)(22/77)(1/4)h

=0.26

The value of x is approximately 2.8462° and the value of maN is 37°.

To find the value of x and maN, we need to use the given information. According to the question, maN is equal to (13x)°.
To solve for x, we can set up an equation:
maN = (13x)°
Now, since we know that maN is equal to 37°, we can substitute this value into the equation:
37° = (13x)°
To isolate x, we divide both sides of the equation by 13:
37° / 13 = (13x)° / 13
This simplifies to:
2.8462° ≈ x°
Therefore, the value of x is approximately 2.8462°.
Now, let's find the value of maN. We already know that maN is equal to (13x)°. Substituting the value of x that we just found, we get:
maN = (13 * 2.8462)°
Simplifying the multiplication:
maN = 37°
So, the value of maN is 37°.

To minimize the surface area of a box with a square base and a fixed volume V, its dimensions should be x = y = z =  (V¹/³). For V = 1000 meters cubed, the dimensions are x = y = z = 10 meters.

To minimize the surface area, we can use the formula for the surface area of a box with a square base: A = 2x² + 4xy, where x = y (square base) and z = V/x². Differentiating A with respect to x and setting the derivative equal to zero, we find the critical points.

A' = 4x - 4V/x³. Setting A' = 0, we get 4x = 4V/x³, and x⁴ = V, so x = (V¹/³). Since x = y, the dimensions are x = y = z = (V¹/³).

For part (ii), let V = 1000 meters cubed. Then, the dimensions are x = y = z = (1000)¹/³ = 10 meters.

For part (iii), sketch the surface area function A(x) = 2x²+ 4x(V/x²) with a reasonable domain, such as [1, 20] meters for x-axis and [300, 2500] meters squared for the y-axis. Label axes appropriately, including units.
