The distance the plane traveled from point A to point B is approximately y - x:

Distance = y - x

≈ 14046.99 feet - 20246.71 feet

≈ -6200.72 feet.

To find the distance the plane traveled from point A to point B, we can use trigonometry and the concept of similar triangles.

Let's denote the distance from point A to the plane as x, and the distance from point B to the plane as y. We are given the altitude of the plane (constant) as 7275 feet.

At point A, Carlos measures an angle of elevation of 20 degrees to the plane, and at point B, he measures an angle of elevation of 37 degrees to the plane.

Using trigonometry, we can set up the following equations:

tan(20 degrees) = 7275 / x,

tan(37 degrees) = 7275 / y.

We can rearrange these equations to solve for x and y:

x = 7275 / tan(20 degrees),

y = 7275 / tan(37 degrees).

Using a calculator, we can evaluate these expressions:

x ≈ 20246.71 feet,

y ≈ 14046.99 feet.

Therefore, the distance the plane traveled from point A to point B is approximately y - x:

Distance = y - x

≈ 14046.99 feet - 20246.71 feet

≈ -6200.72 feet.

Since the distance cannot be negative, we can round the absolute value of the result to the nearest foot:

Distance ≈ 6201 feet.

To solve for the surface area of a rectangular prism, you'll need to find the area of each of its six faces and add them together.

A rectangular prism has three pairs of faces: two each for length (L), width (W), and height (H).

First, find the area of the two faces with dimensions L x W. The area is calculated by multiplying length by width: A₁ = L * W. Since there are two such faces, the total area for these is 2A₁ = 2(L * W).

Next, find the area of the two faces with dimensions L x H. The area is calculated by multiplying length by height: A₂ = L * H. The total area for these faces is 2A₂ = 2(L * H).

Finally, find the area of the two faces with dimensions W x H. The area is calculated by multiplying width by height: A₃ = W * H. The total area for these faces is 2A₃ = 2(W * H).

To find the total surface area of the rectangular prism, add the areas of all six faces together: Surface Area = 2A₁ + 2A₂ + 2A₃ = 2(L * W) + 2(L * H) + 2(W * H).

So, the formula for the surface area of a rectangular prism is Surface Area = 2(L * W + L * H + W * H).

The measure of angle TUV, given that line segment UT is tangent to circle V, and angle VTS is 145, is 55°.

Based on the information provided, you are looking to find the measure of angle TUV, given that line segment UT is tangent to circle V, and angle VTS is 145º.

Since UT is tangent to circle V, it means that angle UTV is a right angle (90º). Now, we know that the sum of the angles in a triangle is 180º. Therefore, to find the measure of angle TUV (m∠TUV), we can use the following formula:

m∠TUV + m∠UTV + m∠VTS = 180º

Substitute the given values:

m∠TUV + 90º + 145º = 180º

Solve for m∠TUV:

m∠TUV = 180º - 90º - 145º

Let's call the initial number of bacteria in the petri dish as $N_0 = 100$. After 12 hours, the number of bacteria triples, which means there are now $3N_0$ bacteria. After another 12 hours, the number of bacteria triples again, which means there are now $3(3N_0) = 9N_0$ bacteria.

We can see a pattern here that after every 12 hours, the number of bacteria is multiplied by 3. Let's calculate the number of bacteria after 1 hour:

$\sf\implies\:N_1 = N_0 \times 3^{1/12}$

After simplifying:

$\sf\implies\:N_1 = 100 \times 3^{1/12}$

Using a calculator, we can find that $\sf\:3^{1/12} \approx 1.1548$. Therefore:

$\sf\implies\:N_1 \approx{\boxed{115.48}}$

So the equivalent hourly rate at which the number of bacteria is increasing is approximately 15.48% per hour.

In general, if the number of bacteria triples every $t$ hours, the equivalent hourly rate can be calculated as:

$\sf\implies\:r = 3^{1/t} - 1$

where $r$ is the hourly rate expressed as a decimal.

The first step in solving the equation is to isolate the radical term, and the second step is to eliminate the radical by raising both sides to the power of 3. Solving this equation for x initially yields x = 0, x = 2, and x = -2. Checking the solutions shows that it is not a real solution.

The first step in solving the equation (4x)[tex]^{1/3}[/tex] - x = 0 is to isolate the radical term by adding x to both sides of the equation. This gives us

(4x)[tex]^{1/3}[/tex]= x.
The second step is to raise both sides of the equation to the power of 3, which eliminates the radical. This results in 4x = x³.

Solving this equation for x initially yields x = 0, x = 2, and x = -2.
Checking the solutions shows that only x = 2 is a valid solution, as plugging it back into the original equation yields (4*2)[tex]^{1/3}[/tex] - 2 = 0. However, plugging in x = 0 results in a division by zero, and plugging in x = -2 yields a negative number under the radical, which is not a real solution.

Using substitution method, the cost of a chicken is $44.56 and the cost of a rabbit is $36.78.

Let's use the substitution method to solve the problem.

Let's assume that the cost of a chicken is "x" dollars and the cost of a rabbit is "y" dollars.

From the first statement, we know that:

5x + 8y = 517 --- equation (1)

And from the second statement, we know that:

8x + 11y = 761 --- equation (2)

Now we can solve for one of the variables in terms of the other from one of the equations, and then substitute that expression into the other equation to solve for the remaining variable.

Solving equation (1) for "y", we get:

y = (517 - 5x) / 8

Now we can substitute this expression for "y" into equation (2), and solve for "x":

8x + 11[(517 - 5x) / 8] = 761

Multiplying both sides by 8 to eliminate the fraction, we get:

64x + 11(517 - 5x) = 6088

Expanding the brackets, we get:

64x + 5687 - 55x = 6088

Combining like terms, we get:

9x = 401

Dividing both sides by 9, we get:

x = 44.56

So the cost of a chicken is $44.56.

Now we can substitute this value for "x" into equation (1) to solve for "y":

5(44.56) + 8y = 517

Simplifying, we get:

222.80 + 8y = 517

Subtracting 222.80 from both sides, we get:

8y = 294.20

Dividing both sides by 8, we get:

y = 36.78

So the cost of a rabbit is $36.78.

Therefore, the cost of a chicken is $44.56 and the cost of a rabbit is $36.78.

The value of the expression 11C7 is 330. This can be calculated using the formula for combinations, which is nCr = n!/r!(n-r)!, where n is the total number of objects and r is the number of objects being selected. So, the correct answer is A).

To calculate the value of the expression 11C7, we need to use the formula for combinations or binomial coefficients, which is

nCr = n! / (r! * (n-r)!)

where n is the total number of items, r is the number of items to be chosen, and ! denotes the factorial operation (the product of all positive integers up to n).

11C7 = 11! / (7! * (11-7)!)

= 11! / (7! * 4!)

= (11 * 10 * 9 * 8 * 7 * 6 * 5) / (4 * 3 * 2 * 1)

To verify that the function f(x) = -4x^2 + 12x - 4ln x attains an absolute maximum and absolute minimum on [1/2,2], we can use the Extreme Value Theorem.

First, we need to check if the function is continuous on the interval [1/2,2] and differentiable on the open interval (1/2,2).

The function is continuous on [1/2,2] because it is a polynomial and the natural logarithm function is continuous on its domain.

To check if it is differentiable on (1/2,2), we need to take the derivative:

f'(x) = -8x + 12 - 4/x

This is defined and continuous on the open interval (1/2,2).

Now we can find the critical points by setting f'(x) = 0:

-8x + 12 - 4/x = 0

Multiplying both sides by x and rearranging, we get:

-8x^2 + 12x - 4 = 0

Dividing by -4, we get:

2x^2 - 3x + 1 = 0

This factors as (2x - 1)(x - 1) = 0, so the critical points are x = 1/2 and x = 1.

We also need to check the endpoints of the interval:

f(1/2) = -4(1/4) + 6 - 4ln(1/2) = 2 - 4ln(1/2)

f(2) = -4(4) + 12(2) - 4ln(2) = 8 - 4ln(2)

Now we can compare the function values at the critical points and endpoints to find the absolute maximum and minimum:

f(1/2) = 2 - 4ln(1/2) ≈ 5.39

f(1) = -4(1) + 12(1) - 4ln(1) = 8

f(2) = 8 - 4ln(2) ≈ 0.31

So the absolute maximum value is 8, which occurs at x = 1, and the absolute minimum value is 0.31, which occurs at x = 2.

Therefore, the function f(x) = -4x^2 + 12x - 4ln x attains an absolute maximum and absolute minimum on [1/2,2], and the absolute maximum value is 8 and the absolute minimum value is 0.31.
To verify that the function f(x) = -4x^2 + 12x - 4ln(x) attains an absolute maximum and minimum on the interval [1/2, 2], we will first find its critical points by taking the first derivative and setting it to zero, and then evaluate the function at the critical points and endpoints.

The first derivative of f(x) is:

f'(x) = -8x + 12 - 4/x

Setting f'(x) to zero, we have:

-8x + 12 - 4/x = 0

Multiplying by x to remove the fraction, we get:

-8x^2 + 12x - 4 = 0

Dividing by -4, we have:

2x^2 - 3x + 1 = 0

Factoring, we get:

(x-1)(2x-1) = 0

This gives us the critical points x = 1 and x = 1/2.

Now, we evaluate f(x) at the critical points and endpoints:

f(1/2) = -4(1/2)^2 + 12(1/2) - 4ln(1/2)
f(1) = -4(1)^2 + 12(1) - 4ln(1)
f(2) = -4(2)^2 + 12(2) - 4ln(2)

Calculating these values, we get:

f(1/2) ≈ 5.386
f(1) = 4
f(2) ≈ -4

The absolute maximum value is ≈ 5.386 at x = 1/2, and the absolute minimum value is ≈ -4 at x = 2.

The resultant component of the vector is calculated as follows;

a = (-9, 6)

b = (3, 1)

The result of 1/3a = ¹/₃ (-9), ¹/₃(6) = (-3, 2)

The result of 2b = 2(3, 1) = (6, 2)

The result of the vector addition is calculated as follows;

1/3a - 2b

= (-3, 2) - (6, 2)

= (-3 -6, 2 -2)

= (-9, 0)

Answer:

60 square inches

Step-by-step explanation:

Pt refers to Pythagoras Theorem. You know two sides of a right angled triangle, how do you find the 3rd side? Pythagoras Theorem. Then the rest is easy. Just do the area of all of the 4 triangles and the area of the square and add them up

The shape of the distribution  in histogram is skewed left and mean=43.071429 and standard deviation= 15.886445 are used together to measure the center and spread of the data.

What is histogram?

A grouped frequency distribution with continuous classes is graphically represented by a histogram. It is an area diagram, and its size is proportional to the frequencies in the associated classes. Due to the base's coverage of the spaces between class boundaries, all of the rectangles in such representations are contiguous.

We can make a sideways histogram. (makes it easier if typing text, but if you are writing on paper then you don't have to make it sideways) Each row will represent a range of 10 (1st row is 10 to 19, 2nd row is 20 to 29, etc)

=> 13 23 28 33 34 38 44 45 49 50 55 59 65 67

The data looks like it is slightly skewed left (hump towards the right [down]). The mean and the standard deviation are used together to measure the center and spread of the data.

Mean = [tex]\frac{ 13+23+28+33+34+38+44+45+49+50+55+59+65+67}{14}=\frac{603}{14}[/tex] = 43.071429

Standard deviation = 15.886445

Hence the shape of the distribution  in histogram is skewed left and mean=43.071429 and standard deviation= 15.886445 are used together to measure the center and spread of the data.
