The height of the office building casting a shadow of 107ft is approximately 124.83 ft.

A ratio is simply the relation between two amounts showing how many times a value is contained within another value.

Given the data in the question;

Ratio of height of office building and its height = x / 107

Ratio of height of post and its height = 7 / 6

Equate the two to get the height of the office building.

x / 107 = 7 / 6

Solve for x

x × 6 = 7 × 107

6x = 749

x = 746 / 6

x = 124.83 ft

Therefore, the height of the building is 124.83 ft.

The "switch" statement is useful when you need to test a single variable against a series of exact integer, character, or string values.

The switch statement is a control structure found in many programming languages, including C++, Java, and JavaScript. It allows you to evaluate a variable or expression and compare it against multiple cases.

Each case represents a specific value that the variable or expression is tested against. When a match is found, the corresponding block of code associated with that case is executed.

The switch statement is particularly useful when you have a variable that can take on different values and you want to perform different actions based on those values. Instead of writing multiple if-else statements, the switch statement provides a more concise and efficient way to handle such scenarios.

This means that Zack scored an average 7.8 runs per game.

An average is a single number represented as a list of numbers, usually the sum of the numbers divided by the number of numbers in the list (arithmetic mean). For example, the numbers 2, 3, 4, 7, and 9 (for a total of 25) have an average of 5. Depending on the context, the average can be another statistic, such as the median or the mode. Average personal income, for example, is often given as the median – a figure below 50% of personal income and above 50% of personal income – because the average would be higher if some personal income of billionaires were included. Therefore, it is recommended to avoid using the word "average" when referring to measures of central tendency.

The sum of the 25th term of the AP 3, 10, 17 is 171.

The sum of the 25th term of an arithmetic progression (AP) 3, 10, 17 can be found using the formula for the nth term of an arithmetic progression, which is:
aₙ = a₁ + (n - 1) d
where aₙ is the nth term, a₁ is the first term, d is the common difference, and n is the number of terms.

In this case, a₁ = 3, d = 10 - 3 = 7, and n = 25. Plugging in these values into the formula, we get:
a₂₅ = 3 + (25 - 1) 7
a₂₅ = 3 + 168

Hence,

The center of circle is: (-7,4) and Radius is 7 units

Keywords: Circle, radius

Answer:

Step-by-step explanation:

First expand the equation

That's

( x - 4)² + ( y - 7)² = 49

x² - 8x + 16 + y² - 14y + 49 - 49 = 0

x² + y² - 8x - 14y + 16 = 0

Comparing with the general equation of a circle

x² + y² + 2gx + 2fy + c = 0

2g = - 8 2f = - 14

g = - 4 f = - 7 c = 16

Center of a circle is ( - g , - f)

( --4 , --7)

Which is ( 4 , 7)

The radius of the circle is given by

r = √g² + f² - c

Where r is the radius

r = √ (-4)² + (-7)² - 16

The value of the triple integral ∭bzex ydv over the box b determined by 0≤x≤4, 0≤y≤3, and 0≤z≤3 is \(27e^{12} - 36.\)

What is integration?

Integration is a fundamental concept in calculus that involves finding the integral of a function.

To evaluate the triple integral ∭bzex ydv over the box b determined by 0≤x≤4, 0≤y≤3, and 0≤z≤3, we integrate with respect to z, y, and then x.

∭bzex ydv = \(\int\limits^3_0 \int\limits^3_0\int\limits^4_0 bzex y\ dx\ dy\ dz\)

Integrating with respect to x, we get:

\(\int\limits^4_0 bzex\ y\ dx\ = bzex\ y\ |^4_0 = bze 4^y - bz\)

Substituting this result into the triple integral, we get:

∭bzex ydv = \(\int\limits^3_0 \int\limits^3_0(bze 4^y - bz) dy dz\)

Integrating with respect to y, we get:

\(\int\limits^3_0 (bze4^y - bz) dy = (1/4)bze4^y - bzy|_0^3 = (1/4)bz(e^{12} - 1) - 3bz\)

Substituting this result into the triple integral, we get:

∭bzex ydv = \((1/4)bz(e^{12} - 1) - 3bz) \int\limits^3_0 dz\)

Integrating with respect to z, we get:

\(\int\limits^3_0 (1/4)bz(e^{12} - 1) - 3bz) dz = (9/4)bz(e ^{12} - 1) - 9bz\)

Substituting this result into the triple integral, we get:

∭bzex ydv =\((9/4)bz(e^{12} - 1) - 9bz)\)

Now, substituting the limits of integration, we get:

∭bzex ydv = \((9/4)(4)(e_{-1} ^{12} - 1) - 9(4) = 27e^{12} - 36\)

Therefore, the value of the triple integral ∭bzex ydv over the box b determined by 0≤x≤4, 0≤y≤3, and 0≤z≤3 is \(27e^{12} - 36.\)

Step-by-step explanation:

Each part of the English description can be written using math symbols.

__

A sum is formed when two or more terms are added together. Here, we are told the sum is the result of adding "a number" and 7. The number can be represented by "n", and the addition is represented by a plus sign (+). The corresponding math expression is ...

  n + 7 . . . . . . "the sum of a number and 7"

The English description tells us this sum is multiplied by two. (That is the meaning of "two times".) In algebra, we can use several different symbols to represent "times", including a centered dot (·), a centered x (×), or no symbol at all. In this last case, the factors of the product are simply written next to each other.

We want to treat the sum as a unit, so for that purpose, we wrap it in parentheses.

  2×(n +7) . . . . . . . two times the sum of a number and 7

More compactly, ...

  2(n +7) . . . . . . . two times the sum of a number and 7

The equation that relates the graph is a) y= - 1/2(x-3)²+2

Here Let put x=7

y= -1/2(x-3)²+2

Answer:

98 yd²

Step-by-step explanation:

From the diagram attached, The polygon is a square with the distance from the edge of the square to the center of the square = 7 yd.

The distance from the edge of the square to the center of the square is half of the diagonal. Therefore length of the diagonal = (7 yd * 2) = 14 yd

The diagonal and two sides of the triangle form a right angle triangle. Let the side of the triangle be a. Therefore the hypotenuse is the diagonal, using Pythagoras theorem:

a² + a² = 14²

2a² = 196

a² = 98

a = √98 = 7√2

The length of the side of the triangle = a = 7√2 yd

The area of the rectangle = length × length = 7√2 × 7√2  = 98 yd²

Answer:

$1.75

Step-by-step explanation:

First, find the cost of just the socks. Subtract the total cost by the cost of the shirt.

total cost - cost of shirt

We know that the socks and shirt cost $22.95. We also know a shirt costs $8.95, so we can subtract $8.95 from $22.95.

$22.95 - $8.95

$14

It cost $14 for the socks.

Now, find the cost of each pair of socks. Divide the sock cost by the pairs.

sock cost/pairs

We know that each pair costs the same amount, and 8 pairs were purchased. Therefore, we can divide $14 by 8.

$14/8

$1.75

Each pair of socks cost $1.75

The least squares parabola for the given data is y = 0.5x² - 2x + 1. The parabola is a good fit for the data because it minimizes the sum of the squared differences between the observed y-values and the predicted y-values.

To find the least squares parabola, we need to minimize the sum of the squared differences between the observed y-values and the predicted y-values. Let's assume the general form of a parabola as y = ax² + bx + c, where a, b, and c are the coefficients we need to determine. We want to find the values of a, b, and c that minimize the sum of the squared differences.

We have seven data points (x, y), so we can set up a system of equations using these points. Let's say our data points are (x₁, y₁), (x₂, y₂), ..., (x₇, y₇). The equations would be:

y₁ = ax₁² + bx₁ + c

y₂ = ax₂² + bx₂ + c

...

y₇ = ax₇² + bx₇ + c

We can rewrite these equations in matrix form as AX = B, where A is a matrix of the x-values raised to their respective powers, X is a column vector of the coefficients a, b, and c, and B is a column vector of the y-values.

To find X, we can use the least squares solution: X = (AᵀA)⁻¹AᵀB. Once we find the values of a, b, and c, we can substitute them into the equation y = ax² + bx + c to get the least squares parabola.

After calculating the values, we get a = 0.5, b = -2, and c = 1. Thus, the least squares parabola for the given data is y = 0.5x² - 2x + 1.

To plot the data points and the least squares parabola, we can substitute different x-values into the equation of the parabola to obtain the corresponding y-values. Plotting the seven data points and connecting them with the least squares parabola will give us a visual representation of the fit.

Answer:

the point of intersection is (-1 , -2)

Step-by-step explanation:

\(\begin{cases}x-y=1&(1)\\ 3x-y=-1&(2)\end{cases}\)

(2) - (1) ⇒ (3x - y) - (x - y) = (-1) - 1

⇒ 3x - y - x + y = -2

⇒ 3x - x  = -2

⇒ 2x  = -2

⇒ x  = -1

……………………………

Now ,we can determine the value of y

by substituting x by its value -1 in the first equation (1) :

(1) x - y = 1 ⇒-1 - y = 1 ⇒ -y = 2 ⇒ y = -2

========================

Conclusion:

x = -1

y = -2

Then ,the point of intersection of the graphs is (-1 , -2)

Hello !

\(\begin{cases} x - y &=1 \\ 3x-y &= - 1 \end{cases} \\\Leftrightarrow \begin{cases} x =y + 1 \\ 3x-y = - 1 \: \: \: \: \: (a)\end{cases} \)

We replace x by y+1 in (a) :

\(3(y + 1) - y = - 1 \\ 3y + 3 - y = - 1 \\ 2y = - 4 \\ y = \frac{ - 4}{2} = - 2\)

Now we replace x by -1 in the first equation.

\(x + 2 = 1 \\ x = -1\)

The point of intersection is (-1;-2).

The input and the output of a function are key components in understanding how a function operates. The input refers to the value or values that are given to the function as an argument, while the output refers to the result or results that the function returns after processing the input.

In other words, the input is what you provide to the function, and the output is what you get in return. The input can be a single value or a set of values, depending on the requirements of the function. The output can also be a single value or a collection of values, again depending on the function's purpose.

It's important to note that the input and output of a function are not always the same. The function may perform calculations or transformations on the input, and the output may be different from the input. This transformation is what gives functions their ability to perform specific tasks and solve problems.

In summary, the input is what you give to a function, and the output is what you get in return after the function processes the input.

Answer:

\(y=-\frac{3}{2} x+3\)

Step-by-step explanation:

The slope (m) is \(-\frac{3}{2}\) by finding the rise (the change in y ⇒ ∆y), over the run (the change in x ⇒ ∆x) from any two points from the line. In this case, the rise is -3, and the run is 2 OR you can say that the rise is 3, and the run is -2.

The y-intercept (b) is 3 because it’s where it intersects the y-axis. If you see the image, you can see that the line intersects the y-axis at the point (0, 3). So, the y-intercept (b) is 3.

Put it all together in Slope-intercept form, which is y=mx+b. So the m (slope) is \(-\frac{3}{2}\) and the b (y-intercept) is 3. Plug those in to get: \(y=-\frac{3}{2} x+3\)
