We know that the height of the rectangular shape is BC=AD= 4 feet and the the area is A=29.2 ft^2. Since the area of our rectangle is given by

we get

By moving the number 4 to the left hand side, we have

which also is the lenght of one side of our parallelogram.

Now, the area of our parallelogram is given by

where the base is given by segment DC=7.3 ft and the height FG=2 BC. Then, we get

by substituting our previous result and BC=4 ft, we obtain

Then, the answer is 58.4 ft^2

Answer:

The ratio of original area to enlarged area is 1/4.

Step-by-step explanation:

Area of original circular garden is

\(\pi {( \frac{d}{2} )}^{2} = \pi \frac{ {d}^{2} }{4} \)

Area of enlarged circular garden is

\(\pi ( { \frac{2d}{2}) }^{2} = \pi {d}^{2} \)

So the ratio of original area to enlarged area is 1/4.

When the function g(x) = 4 - x and fog (x) = 11 - 2x then the function f(x) is

When a function is expressed in terms of another function it can be called a composite function

if g(x) = 4 - x and fog (x) = 11 - 2x

let f(x) = ax + b

fog = f(g(x))

11 - 2x = f((4 - x) + b)

11 - 2x = a(4 - x) + b

11 - 2x = 4a - ax + b

grouping by coefficients

11 - 2x = (4a + b) - ax

equating the coefficients

11 = 4a + b

-2x = -ax

a = 2

plugging a = 2 into 11 = 4a + b

11 = 4 * 2 + b

11 = 8 + b

b = 3

if a = 2  and b = 3 then f(x) = 2x + 3

Answer:

\(V=34.64\ cm^3\)

Step-by-step explanation:

Given that,

The side of an equilateral prism = 4 cm

The altitude of the prism = 5 cm

We need to find the volume of the prism. The formula for the volume of a prism is as follows :

\(V=A\times h\)

Where

A is the area of equilateral triangle, \(A=\dfrac{\sqrt3}{4}a^2\)

So,

\(V=\dfrac{\sqrt3}{4}a^2\times h\\\\V=\dfrac{\sqrt3}{4}\times 4^2\times 5\\\\V=34.64\ cm^3\)

So, the volume of the prism is equal to \(34.64\ cm^3\).

The equation of the circle, obtained by applying the completing the square method to the specified equation indicates that the center and radius of the circle are;

Center (0, 6) and radius 7.5

The general form of the equation of a circle is; (x - h)² + (y - k)² = r², where;

(h, k) = The coordinates of the center of the circle

r = The measure of the length of the radius

The possible equation obtained from a similar question on the internet can be presented as follows;

x² + y² - 12·y - 20.25 = 0

The above equation can be evaluated using the completing the square method and excluding the x² term as follows;

y² - 12·y - 20.25 = 0

y² - 12·y = 20.25

y² - 12·y + (-12/2)² = 20.25 + (-12/2)²

y² - 12·y + (-6)² = 20.25 + (-6)² = 56.25

(y - 6)² = 56.25

Therefore;

y - 6 = √(56.25) = ±7.5

The possible equation of the circle obtained by plugging in the x² term therefore is; (x - 0)² + (y - 6)² = 7.5²

The center of the circle is therefore;

(h, k) = (0, 6)

The radius of the circle, r = 7.5

The possible correction is therefore, option (a), where the 5 is a typing error

Answer:

19 1/11

Explanation:

To solve this problem, we first need to convert all of the fractions to a common denominator. To do this, we find the least common multiple of the denominators, which is 55. Then, we multiply each fraction by the necessary multiple to get the fractions to have a denominator of 55:

24 1/10 - 5 9/11 = (245 + 1)/(105) - (55 + 9)/(115) = 121/50 - 29/55

Next, we can add or subtract the fractions by adding or subtracting the numerators and keeping the denominator the same:

121/50 - 29/55 = (121 - 29)/55 = 92/55

Finally, we can simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 11:

92/55 = (92/11)/(55/11) = 8/5

The final answer is 8/5, which is equivalent to 19 1/11.

The approximate elevation of a person who can see 85 miles to the horizon is 4956 feet above sea level.

What is distance?

Distance is the measure of how far apart two objects or locations are from each other. It is usually measured in units such as meters, kilometers, miles, or feet.

We can use the given formula d(n) = √1.49n to find the elevation n of a person who can see 85 miles to the horizon:

d(n) = 85 miles

√1.49n = 85

Squaring both sides, we get:

1.49n = 85²

n = (85²)/1.49

n ≈ 4956.38

Rounding to the nearest foot, we get:

n ≈ 4956 feet

Therefore, the approximate elevation of a person who can see 85 miles to the horizon is 4956 feet above sea level.

The alternating series test states that if the terms of a series alternate in sign and decrease in absolute value, then the series converges.

Let's first rewrite the given power series as an alternating series. We can do this by multiplying and dividing each term by (-1)^n, which will alternate the sign of the terms:

[infinity]∑ (-1)^n(x-5)^n / (2^n n^2) n=1

Now, we can apply the alternating series test to this series to verify convergence at certain values of x. To use the alternating series test, we need to show that the terms decrease in absolute value. We can do this by taking the absolute value of the terms and comparing them to the next term:

|(-1)^n(x-5)^n / (2^n n^2)| = |(x-5)^n| / (2^n n^2)

To simplify the comparison, we can take the ratio of the absolute values of consecutive terms:

|(x-5)^(n+1) / ((n+1)^2 2(x-5)^n)| = |(x-5) / (2(n+1)^2)|

Now, we need to find values of x for which the series converges. The radius of convergence is given as 2, which means the series converges for |x-5| < 2.

Checking each option:

a. x=6: |6-5| = 1, which is less than 2, so the series converges at x=6.

b. x=4: |4-5| = 1, which is not less than 2, so we cannot use the alternating series test to verify convergence at x=4.

c. x=2: |2-5| = 3, which is not less than 2, so we cannot use the alternating series test to verify convergence at x=2.

d. x=0: |0-5| = 5, which is not less than 2, so we cannot use the alternating series test to verify convergence at x=0.

e. x=-1: |-1-5| = 6, which is not less than 2, so we cannot use the alternating series test to verify convergence at x=-1.

Therefore, we can only use the alternating series test to verify convergence at x=6.

Perpendicular lines have slopes that are opposite reciprocals.

This means we take a number, change its sign, and flop it over.

Here, we have 1/4.

First, we change its sign:

-1/4

Now, we flop it over:

-4

So the slope of the line perpendicular to the given line is -4.

Now, we are given the slope of the line and a point that the line passes through.

We can use the Point-Slope formula:

The t-distribution value is -1.67 for the given mean samples of 35 and 45. Thus, option B is correct.

M₁ = 35

M₂ = 45

SM1-M2 = 6.00

The t-value or t-distribution formula is calculated from the sample mean which consists of real numbers. To calculate the t-value, the formula we need to use here is:

t = (M₁ - M₂) / SM1-M2

Substituting the given values into the formula:

t = (35 - 45) / 6.00

t = -10 / 6.00

t = -1.67

Therefore, we can conclude that the value of t is -1.67 for the samples given.

The measure of the height of the building is approximately 1,154.8 feet.

We can use trigonometry to solve this problem. Let h be the height of the building. Then we have:

tan(30°) = h/2,000

We can solve for h by multiplying both sides by 2,000:

h = 2,000 tan(30°)

Using a calculator, we can evaluate tan(30°) to be approximately 0.5774. Substituting this value, we get:

h = 2,000 × 0.5774

h ≈ 1,154.8

Therefore, the height of the building is approximately 1,154.8 feet.

The integral of f(x,y,z)=8xz over the region in the first octant (x,y,z≥0) above the parabolic cylinder \(z=y^{2}\) and below the paraboloid \(z=8-2x^{2} -y^{2}\) is 128/9.

The first step is to find the bounds of integration. The region in the first octant (x,y,z≥0) is bounded by the planes x=0, y=0, and z=0.

The parabolic cylinder z=y2 is bounded by the planes x=0 and \(z=y^{2}\). The paraboloid \(z=8-2x^{2} -y^{2}\) is bounded by the planes x=0, y=0, and z=8.

The next step is to set up the integral. The integral is:

\(\int\limits {0^{1} } \int\limits {0^{\sqrt{x} } }\int\limits {y^{8}-2x^{2} -y^{2} 8xzdxdy\)

We can evaluate the integral by integrating with respect to z first. The integral with respect to z is:

\(8x^{2} (8-2x^{2}-y^{2} )-8xy^{2} -y^{8} -2x^{2} -y^{2}\)

Simplifying this expression, we get the equation:

\(8x^{2} (8-2x^{2}-y^{2} )-8xy^{2}\)

We can now integrate with respect to x. The integral with respect to x is:

\(4(8-2x^{2}-y^{2} )^{2} -4xy^{2}-0^1\)

Simplifying this expression, we get the equation:

\(4(8-2x^{2}-y^{2} )^{2} -4xy^{2}\)

We can now integrate with respect to y. The integral with respect to y is:

\(4\frac{(8-2-y)^{3} }{3} -4y^{3} -0^1\)

Simplifying this expression, we get the equation:

\(\frac{128}{9}\)

Therefore, the integral of f(x,y,z)=8xz over the region in the first octant (x,y,z≥0) above the parabolic cylinder \(z=y^{2}\) and below the paraboloid \(z=8-2x^{2} -y^{2}\) is \(\frac{128}{9}\).
