The surface area of the figure = 2733.3 sq. in.

First we fine the surface area of the top surface of the figure.

The top surface is an rectangle with length = 19 in. and width = 17 in

Using the formula for the area of rectangle, the area of top face would be,

A₁ = 19 × 17

A₁ = 323 sq. in.

The slant face of the figure is a rectangle with  length = 22 in. and width = 17 in

Using the formula for the area of rectangle, the area of slant surface of the figure would be,

A₂ = 22 × 17

A₂ = 374 sq. in.

There are two parallel trapezoidal surface of the figure with bases 35 in. and 19 in. respectively.

The height of the trapezoid = 20.3 in.

Using the formula for that area of trapezoid, the area of two trapezoidal surface of the figure would be,

A₃ = 2 × (sum of lengths two bases/2) × height

A₃ = 2 × (35 + 19/2) × 20.3

A₃ = 1096.2 sq. in.

The area of the bottom surface would be,

A₄ = 35 × 17

A₄ = 595 sq. in.

The area of right surface would be,

A₅ = 20.3 × 17

A₅ = 345.1 sq. in.

So, the total surface area would be,

A = A₁ + A₂ + A₃ + A₄ + A₅

A = 323 + 374 +  1096.2 +  595 + 345.1

A = 2733.3 sq. in.

Therefore, the surface area of the figure = 2733.3 sq. in.

Answer:

x = - [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

consider the right triangle formed by the x- axis, the y- coordinate of the given point and the radius of the circle 1 , to the point from the centre.

using Pythagoras' identity

x² + ( [tex]\frac{4}{5}[/tex] )² = 1²

x² + [tex]\frac{16}{25}[/tex] = 1 ( subtract [tex]\frac{16}{25}[/tex] from both sides )

x² = 1 - [tex]\frac{16}{25}[/tex] = [tex]\frac{9}{25}[/tex] ( take square root of both sides )

x² = ± [tex]\sqrt{\frac{9}{25} }[/tex] = ± [tex]\frac{\sqrt{9} }{\sqrt{25} }[/tex] = ± [tex]\frac{3}{5}[/tex]

since the given point is in the second quadrant , then

x = - [tex]\frac{3}{5}[/tex]

The slope of the polar curve at θ = π/4 is 24. Therefore, option D is correct.

To find the slope of the polar curve r = 6cos(2θ) - 5 at θ = π/4, we need to find the derivative of r with respect to θ, and then substitute θ = π/4 into the resulting expression.

Using the chain rule of differentiation, we have:

dr/dθ = dr/d(cos(2θ)) * d(cos(2θ))/dθ

To find the first derivative, we can use the power rule of differentiation:

dr/d(cos(2θ)) = -12sin(2θ)

To find the second derivative, we can use the chain rule again:

d(cos(2θ))/dθ = -2sin(2θ)

Substituting these into the expression for dr/dθ, we get:

dr/dθ = -12sin(2θ) * (-2sin(2θ)) = 24sin^2(2θ)

Now, substituting θ = π/4, we get:

dr/dθ|θ=π/4 = 24sin^2(π/2) = 24

The slope of the polar curve at θ = π/4 is therefore 24.

The city with a population of 500,000 would produce 305,000 tons of pollutants.

We have,

Let's call the unknown amount of pollutants in the second city "x".

According to the problem,

The amount of pollution is directly proportional to the number of people. This means that we can set up a proportion:

Pollution/number of people

= pollution/number of people

Using the values we know:

= 21350/35000

= x/500000

Simplifying:

0.61 = x/500000

To solve for x, we can cross-multiply:

0.61 x 500000 = x

x = 305000

Therefore,

Answer:

The formula for simple interest is:

I = P * r * t

Where:

I = Interest earned

P = Principal amount (initial amount deposited)

r = Annual interest rate (as a decimal)

t = Time in years

Using the given values, we have:

P = $500

r = 0.04 (4% expressed as a decimal)

t = 6 years

I = P * r * t

I = $500 * 0.04 * 6

I = $120

So the interest earned after 6 years is $120. To find the total amount of money in the account, we add the interest to the principal:

Total = P + I

Total = $500 + $120

Total = $620

Therefore, there will be $620 in the account after 6 years.

The conclusion is there is not a significant difference between the preference for the three food containers.

The appropriate statistic to use in this case is a chi-squared test. This test will help us determine if there is a significant difference between the preference of the three food containers.

The critical value for the chi-squared test with 2 degrees of freedom is 5.991.

The chi-squared statistic is calculated as follows:

(74-103)²/103 + (103-123)²/123 + (123-103)²/103

= 3.9/3.9

= 1.0

The chi-squared statistic (1.0) is less than the critical value (5.991). Therefore, there is not a significant difference between the preference for the three food containers.

The statistical results can be presented in the following form:

Chi-squared statistic = 1.0

Critical value = 5.991

Therefore, the conclusion is there is not a significant difference between the preference for the three food containers.

An axon is a long, tubelike structure extending from a neuron's cell body branch-like fiber extending in clusters from a neuron's cell body messenger of the nervous system is true.

We have,

An axon is a long, tubelike structure that extends from a neuron's cell body.

It is a specialized fiber that carries electrical impulses, known as action potentials, away from the cell body and towards the axon terminals.

Axons are covered by a fatty substance called myelin, which insulates and protects the axon and helps to speed up the transmission of signals.

At the end of the axon, there are small branches called axon terminals, which release chemicals called neurotransmitters into the synapse, the small gap between the axon terminals and the dendrites of the next neuron in the circuit.

This allows the electrical signal to be converted into a chemical signal and transmitted to the next neuron, continuing the chain of communication in the nervous system.

The probability of at least 8 homes would prefer brand B compare to compare A is given by 0.672.

Sample size 'n'= 25

Proportion of people prefer brand A = 0.4

This implies ,

Proportion of people prefer brand B 'p' = 1 - 0.4

                                                                  = 0.6

Using the binomial distribution.

Let X be the number of homes that prefer brand B out of the 25 homes surveyed.

Then X follows a binomial distribution with parameters n = 25 and p = 0.6

Probability that at least 8 homes would state a preference for brand B. expressed as,

P(X ≥ 8) = 1 - P(X < 8)

Using the binomial distribution, compute P(X < 8) as follows,

P(X < 8) = Σ [²⁵Cₓ] × 0.6ˣ × 0.4²⁵⁻ˣ, for x = 0, 1, 2, ..., 7

where ²⁵Cₓ is the binomial coefficient which represents the number of ways to choose k homes out of 25.

Two 1-quart bottles = 64 fluid ounces (2 x 32)

Two 1-pint bottles = 32 fluid ounces (2 x 16)

One 1-quart bottle and eight 8-ounce fluid glasses = 96 fluid ounces (32 + 8 x 8)
