A rectangle i formed by placing two identical quare ide by ide. The area of the rectangle i 288 quared cm. What i the perimeter of one quare?

Answer:

2.73 meters away from the building.

Step-by-step explanation:

To find the distance from the building to the flagpole, we can use the tangent function. Let's call the distance from the building to the flagpole "d".

The tangent of the angle of elevation is equal to the height of the flagpole (h) divided by the distance from the building to the flagpole (d):

tan 48° = h / d

The tangent of the angle of depression is equal to the distance from the building to the flagpole (d) divided by the height of the observer (3.5 m):

tan 35° = d / 3.5

We can use these two equations to find the value of d. Solving the first equation for h:

h = tan 48° * d

And substituting that into the second equation:

tan 35° = d / (tan 48° * d / 3.5)

Solving for d:

d = 3.5 * tan 35° / tan 48°

Using a calculator, we can find that:

d = 3.5 * tan 35° / tan 48° = 3.5 * 1.3602668 / 1.7415198 = 2.73 m

So the flagpole is 2.73 meters away from the building.

Answer: Musical preferences

A variable is a lurking variable if it can influence an explanatory/response relationship. So it must be related to both the explanatory and response variable. It is not likely your musical preferences affect mortality or how much sweetener you consume.

The number of soft drink brands available for purchase is not a lurking variable in this scenario. Correct option is C.

The statement is asking which of the given variables is not a lurking variable in the scenario where Shawna is considering the correlation between the calories of sweeteners consumed and the mortality rates among women, and is trying to determine whether drinking more soft drinks will lead to a higher chance of her dying.

A lurking variable is a variable that is not included in the analysis, but has an effect on the relationship between the variables being studied. In this case, the variables being studied are the calories of sweeteners consumed and the mortality rates among women, and the effect of drinking more soft drinks on the chances of dying.

Out of the given variables, the number of soft drink brands available for purchase would not be a lurking variable, as it does not have an effect on the relationship being studied.

Shawna's weight, the time of day she exercises, and the amount of caffeine available in soft drinks could all potentially have an effect on the relationship being studied, either as confounding variables or moderators.

For example, Shawna's weight could be a confounding variable, as it is associated with both sweetener consumption and mortality rates. The time of day she exercises could be a moderator, as exercise may affect the metabolism of sweeteners and caffeine, which could in turn affect mortality rates.

The amount of caffeine available in soft drinks could be a confounding variable, as caffeine consumption is associated with both sweetener consumption and mortality rates.

In summary, the number of soft drink brands available for purchase is not a lurking variable in this scenario, while Shawna's weight, the time of day she exercises, and the amount of caffeine available in soft drinks could potentially be confounding variables or moderators that need to be accounted for in the analysis.

The measure of ∠R =49, ∠T = 61 , ∠M = 70 , ∠N = 61, x = 7 and y = 13.

What are Congruent triangles?

When all three corresponding sides are the same length and all three corresponding angles are the same size, two triangles are said to be congruent.

Given, ΔLMN ≅ ΔRST,

So, ∠L = ∠R  = 49

     ∠M = ∠S = 70

     ∠N = ∠T = 4y + 9

Now, In triangle RST,

∠R + ∠S + ∠T = 180 ( sum of all angles of a triangle is 180 )

49 + 70 + ∠T = 180

   ∴ ∠T = 61 = ∠N

and, 4y + 9 = 61

       y = 13.

Now, In triangle LMN ,

∠L + ∠M + ∠N = 180

49 + 10x + 61 = 180

In all three cases, the height of the cone is proportional to the volume and inversely proportional to the square of the radius. So, if we know the volume and radius of a cone, we can use the formula for h to find its height.

[tex]\text{Height } = h = \frac{3V}{\pi r^2} = \frac{3V}{\pi (2^2)} = \frac{3V}{4\pi}[/tex]

The volume of a cone is given by the formula V = (1/3)πr²h, where V is the volume, r is the radius, and h is the height of the cone.

If we rearrange this formula to solve for h, we get h = 3V / (πr²). This means that the height of a cone is directly proportional to the volume and inversely proportional to the square of the radius.

a. If the radius of a cone is 2 inches and its volume is given, we can find its height by plugging in the values of V and r into the formula for h.

[tex]h = \frac{3V}{\pi r^2} = \frac{3V}{\pi (2^2)} = \frac{3V}{4\pi}[/tex]

b. Similarly, if the radius is 3 inches, the height would be:

[tex]h = \frac{3V}{\pi r^2} = \frac{3V}{\pi (3^2)} = \frac{3V}{9\pi}[/tex]

c. If the radius is 6 inches, the height would be:

[tex]h = \frac{3V}{\pi r^2} = \frac{3V}{\pi (6^2)} = \frac{3V}{36\pi}[/tex]

In all three cases, the height of the cone is proportional to the volume and inversely proportional to the square of the radius. So, if we know the volume and radius of a cone, we can use the formula for h to find its height.

Answer:

To rewrite the expression 27 - 4x + x² in the form (x + a)² + b, we can complete the square.

Starting with x² + (-4x) + 27:

x² - 4x + 4x² = 4x² - 4x

Adding (4/2)² = 4 to both sides:

4x² - 4x + 4 = 4x² - 4x + 4

The expression is now in the form (x - 2)² + 0, so a = -2 and b = 0.

Therefore, 27 - 4x + x² = (x - 2)² + 0.

The left Riemann Sum approximation for the integral of 20(4x² - 2x)dx over the interval [0, 20] with four equal subintervals is 165250.

In calculus, the integral is a mathematical tool that allows us to find the area under a curve. It is an important concept that is used in many fields of science and engineering. One way to estimate the value of an integral is by using a Riemann Sum, which involves dividing the region under the curve into small rectangles and adding up their areas.

In this case, we will be using a left Riemann Sum with four equal subintervals to estimate the integral of 20(4x² - 2x)dx.

To use a left Riemann Sum, we need to first divide the interval of integration into equal subintervals. In this case, we have four subintervals of width

=> (b - a)/n = (20 - 0)/4 = 5.

The left endpoint of each subinterval will be used as the height of the rectangle that represents the area under the curve in that subinterval.

Next, we need to evaluate the function 20(4x² - 2x) at the left endpoints of each subinterval. These values will be used as the heights of the rectangles. The left endpoints are 0, 5, 10, and 15, so we have:

f(0) = 20(4(0)² - 2(0)) = 0

f(5) = 20(4(5)² - 2(5)) = 1900

f(10) = 20(4(10)² - 2(10)) = 7200

f(15) = 20(4(15)² - 2(15)) = 15150

We can now find the area of each rectangle by multiplying its height by its width (5). The total area is the sum of these areas:

(0)(5) + (1900)(5) + (7200)(5) + (15150)(5) = 165250

An equation is a mathematical statement that expresses the equality of two expressions. It typically consists of two parts: the left-hand side and the right-hand side, separated by an equal sign (=). The left-hand side and right-hand side can contain variables, numbers, and mathematical operations such as addition, subtraction, multiplication, and division.

Let's call the number we're looking for "x". We can use the information given in the problem to set up two equations:

0.7x = 224 (equation 1)

0.95x = 304 (equation 2)

We want to find 25% of the same number, which can be written as 0.25x. We can solve for x using either equation 1 or equation 2 and then plug that value into 0.25x to find the answer.

Let's solve for x using equation 2:

0.95x = 304

x = 304/0.95

x = 320

Now that we know x is 320, we can find 25% of that number:

If the wax was priced at $1.67 per square foot, it would cost $1,664.99 to wax the entire floor. The right answer is C.

The floor is made up of a trapezoid and a rectangle.

The area of a trapezoid can be calculated as:

A = (b₁ + b₂)/2 x h

Where b₁ and b₂ are the lengths of the bases and h is the height.

The trapezoid is 14 feet tall, and its bases are 33 feet long and (28 - 19) or 9 feet wide. Thus, its area is:

A = (33 + 9)/2 x  14

A = 294 square feet

The rectangle is 37 feet tall with a 19-foot base. Thus, its area is:

A = 19 x 37

A = 703 square feet

The area of the triangle and trapezoid together make up the overall area of the figure.

A = 294 + 703

A = 997 square feet

Finally, to find the cost of the wax, we multiply the area by the cost per square foot:

Cost = 997 * $1.67

3. Determine the updated median and mean.

4. Evaluate the original mean and median in comparison to the new mean and median. Depending on whether the collection of numbers is even or odd, the median will decline while the mean will increase.

We must first determine the mean and median of the initial set of data in order to evaluate how the addition of a smaller data point will impact those values. Adding together all the values and dividing by the total number of values yields the mean. We place the middle value in the set of integers after sorting them from least to largest to determine the median. We include the new, smaller data point in the set after finding the mean and median. We next perform the same calculations as previously to determine the new mean and median. Finally, we contrast the updated mean and median with the baseline values. The median may stay the same or drop depending on whether the set of numbers is even or odd, while the mean often decreases as it is compared to other values.

We can use the Pythagorean theorem to solve this problem. Let's call the distance from the ball to the center of the green "d". We know that the marker is 150 yards from the center of the green, and the golfer has paced off 35 yards in a direction 110 degrees from the marker.

Let's use x to represent the horizontal distance from the marker to the ball, and y to represent the vertical distance from the marker to the ball. Then, we have:

x = 35 * cos(110)

y = 35 * sin(110)

Using the Pythagorean theorem, we can find the distance "d" from the ball to the center of the green:

d^2 = x^2 + (y + 150)^2

Plugging in the values for x and y, we get:

d^2 = 35^2 * cos(110)^2 + (35 * sin(110) + 150)^2

d^2 = 1225 + (150 + 35 * sin(110))^2

Using a calculator, we can find that sin(110) = 0.939, so:

d^2 = 1225 + (150 + 31.65)^2

d^2 = 1225 + (181.65)^2

d^2 = 1225 + 32762.7225

Taking the square root of both sides:

d = sqrt(1225 + 32762.7225)

d = sqrt(33987.7225)

d = 183.83

Rounding to the nearest yard:

d = 184 yards

So, the ball is 184 yards from the center of the green.

The Roth IRA will provide Ethan with the most future benefit, with the IRA valued at $195,902.08 and the Roth at $211,633.75. The difference in the future value of the two accounts is $15,731.67.

A purchase made with the intention of creating income or capital growth is known as an investment. An asset's value increasing over time is referred to as appreciation. When a person invests in a thing, they do not intend to utilise it as a source of immediate consumption, but rather as a tool for future economic growth.

The Roth IRA will provide Ethan with the most future benefit. The IRA will be valued $195,902.08 after 30 years, while the Roth IRA will be worth $211,633.75. As a result, the Roth IRA is valued $15,731.67 more than the IRA.

To determine the IRA's future value, use the formula FV = P(1+r)n, where P is the monthly payment, r is the interest rate, and n is the number of periods (in this case, 30 years). With our data in, we get: FV = 416.66(1+0.025)30 = $195,902.08.

We may apply the same approach to compute the future value of the Roth IRA, but with a $5,000 yearly payout. With our values in, we get: FV = 5000(1+0.025)30 = $211,633.75.

The difference in the future value of the two accounts is $15,731.67, which is the amount that the Roth IRA will be worth more than the IRA.

The inverse function of f(x) = [tex]\frac{x-7}{x+4}[/tex] is f⁻¹(x) = [tex]\frac{4x+7}{1-x}[/tex].

A function that can reverse into another function is known as an inverse function or anti function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f-1" or "F-1." Here, (-1) should not be confused with an exponent or a reciprocal.

Given that the function is f(x) = [tex]\frac{x-7}{x+4}[/tex]

Change f(x) (or whatever the function name is) to "y".  In this case you'd get:

y = [tex]\frac{x-7}{x+4}[/tex]

Now, switch x and y.  Wherever you see y, put x.  And wherever you see x, put y.

x = [tex]\frac{y-7}{y+4}[/tex]

Solve the new equation for y.

x (y + 4) = y - 7

xy + 4x = y - 7

4x + 7 = y - xy

4x + 7 = y (1 - x)

y = [tex]\frac{4x+7}{1-x}[/tex]

Change y back to function notation.  The correct notation for the "inverse of f(x)" is "f⁻¹(x)".  So that would give you:

The actual distance between the basketball court and the pool is 37.5 feet

Distance refers to the amount of space between two objects or points. It is a measure of how far apart two things are from each other.

The scale of the model is 3 inches = 5 feet. This means that every 3 inches on the model represents 5 feet in actual size. We are given that the distance between the basketball court and the pool on the model is 22.5 inches. To find the actual distance between these areas, we need to use the scale.

We can start by setting up a proportion using the scale. We know that 3 inches on the model represents 5 feet in actual size. Therefore, we can say that:

3 inches / 5 feet = 22.5 inches / x

We are trying to solve for x, which represents the actual distance between the basketball court and the pool. To solve for x, we can cross-multiply and simplify the equation:

3 inches x x = 5 feet x 22.5 inches

3x = 112.5

x = 37.5 feet
