Answer:

Step-by-step explanation:

First, calculate the angle of FDE (assume it as α) by:

[tex]EF=\frac{\alpha}{360}\times(2\pi)(DE) \rightarrow 2\pi = \frac{\alpha}{360}(2\pi)(6)[/tex]

[tex]\alpha=60^{0}[/tex]

So, use this angle to calculate the area of FDE (unshaded region):

[tex]A_{US}=\frac{\alpha}{360}\times(\pi)(DE)^{2}=\frac{60}{360}(\pi)(6^{2})=6\pi[/tex]

So, the shaded region can be determined by:

[tex]A_{S}=A-A_{US}=\pi(DE)^{2}-6\pi=36\pi-6\pi=30\pi=\frac{60}{2}\pi[/tex]

Answer:

9

Step-by-step explanation:

the equation for the line should be:

y=9x-10

The slope of the line that passes through the point (−10,9) and (10,18) is undefined.

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

We need to find the slope of the line that passes through the point (−10,9) and (10,18)

Where x₁ - x coordinate, y₁ - y coordinate, m - slope

Slope: (18 - 9) / ( -10 + 10)

m = 9/0

So, the slope is undefined.

Hence, the slope of the line that passes through the point (−10,9) and (10,18) is undefined.

Answer:

x=237/7 and y=-199/7

Explanation:

Multiply the second equation by 2, then add the equations together.

(−2x+3y=−153)

2(x+2y=−23)

Becomes:

−2x+3y=−153

2x+4y=−46

Add these equations to eliminate x:

7y=−199

Then solve 7y=−199 for y:

7y=−199

(Divide both sides by 7)

y=−199/7

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

−2x+3y=−153

Substitute −199/7 for y in−2x+3y=−153:

Add 597/7 to both sides

Divide both sides by -2

Step-by-step explanation:

The surface area of the larger solid is approximately 971.13 m².

A scale factor is the ratio of the corresponding sides of two similar objects.

Let's find the scale factor as follows:

z = scale factor

x = the volume of the larger solid

y = the volume of the smaller solid

Therefore,

z³ = x / y

z³ = 1408 / 594

z = ∛1408 / 594

z = 11.2081573 / 8.40611799

z = 1.33

Therefore,

let's find the surface area of the larger solid.

The scale factor squared is equal to the surface area of the larger solid divided by the surface area of the smaller solid. Therefore,

z² = larger solid / 549

surface area of the larger solid =  1.33² × 549

surface area of the larger solid = 1.7689 × 549

surface area of the larger solid = 971.1261

surface area of the larger solid = 971.13 m²

Answer:

V = π ∫₀² (y² − 8y + 6√(2y)) dy

or

V = π ∫₀² (6x − 5x² + x³) dx

Step-by-step explanation:

y₁ = 0.5x²

y₂ = x

First, find the intersections of the curves.

0.5x² = x

x² = 2x

x² − 2x = 0

x (x − 2) = 0

x = 0 or x = 2

So the points of intersection are (0, 0) and (2, 2).

When we revolve this region about the line x = 3, we get a hollow shape that looks like an upside-down funnel, or a volcano.

One option is to use washer method to find the volume, by cutting a thin horizontal slice of thickness dy, inner radius 3−x₁ = 3−√(2y), and outer radius of 3−x₂ = 3−y.

V = ∫₀² π [(3−y)² − (3−√(2y))²] dy

V = ∫₀² π (9 − 6y + y² − 9 + 6√(2y) − 2y) dy

V = π ∫₀² (y² − 8y + 6√(2y)) dy

Another option is to use shell method to find the volume, by cutting a thin vertical slice of thickness dx, radius 3−x, and height y₂−y₁ = x−0.5x².

V = ∫₀² 2π (3 − x) (x − 0.5x²) dx

V = ∫₀² 2π (3x − 1.5x² − x² + 0.5x³) dx

V = ∫₀² 2π (3x − 2.5x² + 0.5x³) dx

V = π ∫₀² (6x − 5x² + x³) dx

The second option is arguably easier to evaluate, but either one will get you the same answer (V = 8π/3).

~Lenvy~

The expression which is equivalent to 5x² - 18x + 9 is (5x – 3)(x - 3).

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given expression is,

5x² - 18x + 9

We have to find the equivalent expression of this.

We have to factor this.

Using quadratic formula,

x = -(-18) ± √[(-18)² - (4 × 5 × 9)] / (2 × 5)

  = (18 ± √144) / 10

  = (18 ± 12) / 10

x = 3 and x = 3/5

So the expression can be factored as

(x - 3)(x - 3/5) = 0

(x - 3)(5x - 3) = 0

Hence the correct option is (5x – 3)(x - 3).

Basic quadratic equation has this following form:

Using the normal probability distribution and the central limit theorem, it is found that the probability is of 0.9974 = 99.74%, which means that the pilot should take action.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, for the population, the mean and the standard deviation are given by, respectively:

[tex]\mu = 185.47, \sigma = 39[/tex].

For a sample of 37 passengers, we have that:

[tex]n = 37, s = \frac{39}{\sqrt{37}} = 6.4116[/tex]

The probability that the aircraft is overloaded is one subtracted by the p-value of Z when X = 167.6, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{167.6 - 185.47}{6.4116}[/tex]

[tex]Z = -2.79[/tex]

[tex]Z = -2.79[/tex] has a p-value of 0.0026.

1 - 0.0026 = 0.9974.

There is a 0.9974 = 99.74% probability that the aircraft is overloaded. Since this is a very high probability, the pilot should take action.

after approximately 137 minutes, there will be 10 bacteria remaining.

To find the time at which there will be 10 bacteria remaining, we can use the half-life model for exponential decay, which is given by:

N(t) = N₀ * [tex](1/2)^{(t / t_{half})[/tex]

where:

N(t) = the number of bacteria at time t

N₀ = the initial number of bacteria

t = time (in minutes)

t_half = the half-life of the bacteria

We are given that the initial number of bacteria (N₀) is 500 and after 17 minutes there are 150 bacteria (N(17) = 150).

Let's use this information to find the value of k (the decay constant):

150 = 500 * [tex](1/2)^{(17 / t_{half})[/tex]

Divide both sides by 500:

[tex](1/2)^{(17 / t_{half})[/tex] = 150 / 500

[tex](1/2)^{(17 / t_{half})[/tex] = 0.3

Now, we can write the equation as an exponent:

17 / t_half = log base (1/2) of 0.3

Using logarithms:

t_half = 17 / log base (1/2) of 0.3

Now, calculate t_half:

t_half = 17 / log base 2 of 0.3 ≈ 38.555

Now, we can find the time at which there will be 10 bacteria remaining (N(t) = 10):

10 = 500 * [tex](1/2)^{(t / 38.555)[/tex]

Divide both sides by 500:

[tex](1/2)^{(t / 38.555)[/tex] = 10 / 500

[tex](1/2)^{(t / 38.555)[/tex] = 0.02

Write the equation as an exponent:

t / 38.555 = log base (1/2) of 0.02

Using logarithms:

t = 38.555 * log base 2 of 0.02 ≈ 137.08

Rounding to the nearest whole number:

t ≈ 137

So, after approximately 137 minutes, there will be 10 bacteria remaining.
