The length of the hypotenuse of each right triangle to the nearest tenth of an inch is 24 inches.

Here, two right triangles with legs each measuring 17 inches are created when the square piece of metal is sliced diagonally.

We will apply the Pythagorean Theorem to find the length of the hypotenuse.

The Pythagorean theorem states that square of hypotenuse is equal to the sum of the squares of opposite side and adjacent side.

Now,

[tex]Hypotenuse^{2} = 17^{2}+ 17^{2} \\Hypotenuse^{2} =289+289\\Hypotenuse^{2} =578\\Hypotenuse=\sqrt{ 578}\\Hypotenuse=24.04[/tex]

⇒ Hypotenuse ≈ 24 inches (to the nearest tenth of an inch)

The derivative of the given function with respect to x is:
f'(x) = e^(x^2 + 1) * (1 + 2x^2)

To find the derivative of the given function. Let's first rewrite the function for clarity: f(x) = x * e^(x^2 + 1).

To find the derivative f'(x) with respect to x, we'll apply the product rule since we have a product of two functions: x and e^(x^2 + 1). The product rule states that if you have a function f(x) = g(x) * h(x), then f'(x) = g'(x) * h(x) + g(x) * h'(x).

In this case, g(x) = x and h(x) = e^(x^2 + 1). First, let's find the derivatives g'(x) and h'(x):

g'(x) = d/dx (x) = 1
h'(x) = d/dx (e^(x^2 + 1)) = e^(x^2 + 1) * d/dx (x^2 + 1) = e^(x^2 + 1) * (2x)

Now, we can apply the product rule:

f'(x) = g'(x) * h(x) + g(x) * h'(x) = 1 * e^(x^2 + 1) + x * (e^(x^2 + 1) * 2x)

Simplifying the expression, we get:

f'(x) = e^(x^2 + 1) + 2x^2 * e^(x^2 + 1)

The following is the value of x and mBD: x = 83/6 and mBD⌢ = 83°.

Given circle E (⊙E) with diameter AC, we have the following information:

1. m∠CED = (3x)°
2. m∠BEC = (3x + 2)°
3. m∠AEB = (6x + 7)°

Since AC is the diameter of the circle, the inscribed angle ∠AEB is subtended by the diameter and thus forms a semicircle. In a semicircle, the inscribed angle is always a right angle. Therefore, m∠AEB = 90°. We can now set up the equation:

(6x + 7)° = 90°

Solving for x:
6x = 83
x = 83/6

Now, we need to find the measure of arc BD (mBD⌢). We can do this by finding the measure of angle BEC, as the measure of an inscribed angle is half the measure of its intercepted arc.

m∠BEC = (3x + 2)° = (3(83/6) + 2)° = (83/2)°

Since the measure of an inscribed angle is half the measure of its intercepted arc:

mBD⌢ = 2(m∠BEC) = 2(83/2)° = 83°

If the null hypothesis is rejected in a chi-square test of independence, it means that there is a significant association between the two variables being studied. In this case, the fear of crime is dependent on one's perception of whether their neighborhood is a high crime area or not.

Therefore, the most appropriate conclusion that can be made is that there is a significant relationship between the two variables, and one's perception of their neighborhood being a high crime area or not is a predictor of fear of crime. However, the chi-square test of independence does not determine causality, so it is not possible to conclude which variable is causing the other.

To determine the domain of the function (g o f o g)(x), we need to consider the domains of the functions g(x) and f(x), as well as the composition of these functions.

Let's assume that the domain of g(x) is G and the domain of f(x) is F.

Since (g o f o g)(x) means that we apply the function g to f(x), and then apply g to the result again, we need to ensure that the output of f(x) is a valid input for g(x).

Therefore, the domain of (g o f o g)(x) is the set of all values of x in F such that g(f(x)) is in G, and g(y) is in G for all y in the range of g(f(x)).

In other words, the domain of (g o f o g)(x) is the set of all x in F such that f(x) is in the domain of g, and g(f(x)) is in the domain of g.

The maximum area of the quadrilateral is achieved when it is a square with a side length of 50cm, resulting in an area of 2500cm².

This is because a square has equal sides and equal angles,

resulting in the most efficient use of the perimeter to enclose the maximum area.

To see why, consider a rectangle with a perimeter of 200cm.

If the rectangle is long and thin, with one side much longer than the others,

then it will have a smaller area than a square with the same perimeter.

This is because the longer sides of the rectangle will be less effective at enclosing area than the shorter sides.

The expression equation y = sin x + cos x / csc x can be simplified to y = cos x sin^2 x + cos^2 x.

To simplify the expression, we can first replace csc x with 1/sin x. This gives us y = sin x cos x + cos^2 x / sin x.

Next, we can factor out cos x from the numerator of the second term to get y = cos x (sin x + cos x) / sin x.

Using the identity sin^2 x + cos^2 x = 1, we can replace sin^2 x with 1 - cos^2 x in the numerator of the first term. This gives us y = cos x (1 - cos^2 x) / sin x + cos x (sin x + cos x) / sin x.

Simplifying the expression further, we get y = cos x (1 - cos^2 x + sin x + cos x) / sin x.

Finally, we can combine the terms in the numerator to get y = cos x (sin^2 x + 2cos x sin x + 1) / sin x.

Using the identity sin^2 x = 1 - cos^2 x, we get y = cos x (3cos^2 x + 2cos x) / sin x.

Simplifying the expression, we arrive at y = cos x (cos x + 2) (3cos x + 2) / sin x.

Therefore, the simplified expression is y = cos x sin^2 x + cos^2 x, which can also be written as y = cos x (sin x)^2 + cos^2 x.

The perimeter of the triangle formed by joining the midpoints of the sides of the original triangle is 3.

To find the perimeter of the triangle formed by joining the midpoints of the sides of the original triangle, we first need to find the midpoints. The midpoint of a side of a triangle is the point that is exactly halfway between the endpoints of that side.

Using the formula for the midpoint of a line segment ((x1+x2)/2, (y1+y2)/2), we can find the midpoints of the sides with lengths 9, 12, and 15:

Midpoint of the side with length 9: ((9+12)/2, (0+0)/2) = (10.5, 0)

Midpoint of the side with length 12: ((9+15)/2, (0+0)/2) = (12, 0)

Midpoint of the side with length 15: ((12+9)/2, (0+0)/2) = (10.5, 0)

Note that all three midpoints lie on the x-axis.

Now we can find the lengths of the sides of the triangle formed by joining the midpoints. These sides are the line segments connecting the midpoints, and their lengths are equal to the distances between the midpoints:

Length of the side connecting (10.5, 0) and (12, 0):

d = sqrt((12-10.5)^2 + (0-0)^2) = 1.5

Length of the side connecting (10.5, 0) and (10.5, 0):

d = sqrt((10.5-10.5)^2 + (0-0)^2) = 0

Length of the side connecting (12, 0) and (10.5, 0):

d = sqrt((10.5-12)^2 + (0-0)^2) = 1.5

So the triangle formed by joining the midpoints of the sides of the original triangle is an isosceles triangle with two sides of length 1.5 and one side of length 0. The perimeter of this triangle is:

Perimeter = 1.5 + 1.5 + 0 = 3

Last week, the ratio of bananas sold to watermelons sold was 4 : 3.

This ratio means that for every 4 bananas sold, the number of watermelons sold was 3.

Since there were 48 bananas sold, we can find the number of watermelons sold by subtracting 12 from 48:

48 bananas - 12 = 36 watermelons

Now, we can determine the ratio of bananas sold to watermelons sold. The ratio would be:

Bananas : Watermelons = 48 : 36

To simplify this ratio, we can divide both numbers by their greatest common divisor (GCD), which in this case is 12:

48 ÷ 12 = 4
36 ÷ 12 = 3

So, the simplified ratio is:

4 : 3

Approximately 378 people can fit in a passenger car with a length of 70 feet and a width of 9 feet.

To determine the number of people who can fit in a passenger car with a length of 70 feet and a width of 9 feet, we need to consider the available space inside the car and the amount of space required per person.

Assuming that the passenger car is a rectangular box shape, the volume of the car can be calculated as follows:

Volume of car = Length x Width x Height

Since we are only interested in the number of people who can fit in the car, we will assume a standard height of 6 feet for simplicity. Therefore, the volume of the car can be calculated as follows:

Volume of car = 70 feet x 9 feet x 6 feet

Volume of car = 3,780 cubic feet

Next, we need to determine the amount of space required per person. This can vary depending on the seating arrangement and the size of the individuals, but as a general rule, we can estimate that each person requires approximately 10 to 12 cubic feet of space in a seated position.

Assuming we use the lower end of that estimate and allocate 10 cubic feet of space per person, we can calculate the number of people who can fit in the car as follows:

Number of people = Volume of car / Space per person

Number of people = 3,780 cubic feet / 10 cubic feet per person

Number of people = 378 people

Therefore, if we assume a standard height of 6 feet and allocate 10 cubic feet of space per person, approximately 378 people can fit in a passenger car with a length of 70 feet and a width of 9 feet. However, it is important to note that this is just an estimate and the actual number of people who can fit in the car will depend on factors such as the seating arrangement and the size of the individuals.

The volume of the solid is 32/15 cubic units.

To find the volume of the solid, we need to integrate the area of each square cross section perpendicular to the x-axis over the interval [a, b], where a and b are the x-coordinates of the intersection points of f(x) and g(x):

First, we find the intersection points of the two functions:

x²+1 = 2x+1

x² - 2x = 0

x(x-2) = 0

x = 0 or x = 2

So, a = 0 and b = 2.

Next, we find the side length of each square cross section. Since the cross section is a square, the side length is equal to the difference between the y-coordinates of the functions f(x) and g(x) at each x:

Side length = f(x) - g(x) = (x²+1) - (2x+1) = x² - 2x

Finally, we integrate the area of each square cross section over the interval [0, 2] to get the volume of the solid:

V = ∫[0,2] (x² - 2x)² dx

V = ∫[0,2] (x⁴- 4x³ + 4x²) dx

V = [1/5 x⁵ - 1 x⁴ + 4/3 x³] [0,2]

V = (1/5 x⁵ - 1 x⁴ + 4/3 x³)|[0,2]

V = (1/5(2⁵) - 1(2⁴) + 4/3(2³)) - (1/5(0⁵) - 1(0⁴) + 4/3(0³))

V = (32/5 - 16/3)
