What is the perimeter of the rectangle pictured below? Show all work for full credit.
Answer:
≈38.57 units.
Step-by-step explanation:
To find the perimeter of a rectangle, we need to add up the lengths of all its sides.
First, gather the coordinates:
R - (4, 5)
U - (8, -3)
F - (-6, 0)
O - (-2, -8)
Using the coordinates given, we can calculate the lengths of the sides of the rectangle using the distance formula:
d = √((x2 - x1)^2 + (y2 - y1)^2)
So, for the rectangle with vertices R, U, F, and O, we have:
Side RU: d = √((8 - 4)^2 + (-3 - 5)^2) = √(16 + 64) = √80
Side UF: d = √((-6 - 8)^2 + (0 - (-3))^2) = √(196 + 9) = √205
Side FO: d = √((-6 - (-2))^2 + (0 - (-8))^2) = √(16 + 64) = √80
Side OR: d = √((-2 - 4)^2 + (-8 - 5)^2) = √(36 + 169) = √205
Since opposite sides of a rectangle are congruent, we have RU = FO and UF = OR. Therefore, the perimeter of the rectangle is:
Perimeter = RU + UF + FO + OR
Perimeter = √80 + √205 + √80 + √205
Perimeter ≈ 38.57
Therefore, the perimeter of the rectangle is approximately 38.57 units.
Find each length. Round to the nearest hundredth. 40. XZ
In right angle triangle ΔXYZ in which ∠XYZ = 90° and ∠XZY i= 25°.
YZ = 33 inch, the length of XZ to the nearest hundredth is approximately 13.99 inches.
What is trigonometric function?A trigonometric function is a mathematical function that relates the angles of a right triangle to the ratios of its sides. Three basic trigonometric functions are sine (sin), cosine (cos), and tangent (tan).
In a right triangle, if one angle is θ (where θ is not the right angle), then we can define the following trigonometric functions:
sine of θ (sin θ): the ratio of the length of the side opposite θ to the length of the hypotenuse
cosine of θ (cos θ): the ratio of the length of the adjacent side to the length of the hypotenuse
tangent of θ (tan θ): the ratio of the length of the side opposite θ to the length of the adjacent side
We can use the trigonometric function sine to relate the lengths of the sides in the right triangle XYZ. In particular, we know that:
sin(25°) = XZ / 33
To solve for XZ, we can multiply both sides by 33 and simplify:
XZ = 33 sin(25°)
XZ ≈ 13.99 (rounded to the nearest hundredth)

In a laboratory experiment, the population of bacteria in a petri dish started off at 7400 and is growing exponentially at 13% per hour. Write a function to represent the population of bacteria after t hours, where the rate of change per minute can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per minute, to the nearest hundredth of a percent.
The function to represent the bacteria population after t hours is f(t) = 7400 * [tex]e^(0.13/60 * t)[/tex].
What is derivative?A derivative is a measure of how much a function changes as its input value changes. It is defined as the limit of the rate of change of the function with respect to its input as the change in the input approaches zero.
According to question:The function to represent the bacteria population after t hours, where the function's constant can be used to calculate the rate of change per minute is:
f(t) = 7400 * [tex]e^(0.13/60 * t)[/tex]
where:
f(t) = population of bacteria after t hours
e = Euler's number (approximately 2.71828)
t = time in hours
0.13/60 = rate of change per minute (converted from 13% per hour)
To determine the percentage rate of change per minute, we can calculate the derivative of the function with respect to time (t):
df/dt = 7400 * 0.13/60 * [tex]e^(0.13/60 * t)[/tex]
At t = 0 (the start of the experiment), the rate of change per minute is:
df/dt = 7400 * 0.13/60 * [tex]e^(0.13/60 * 0)[/tex] = 12.1166
To express this rate of change as a percentage, we can divide it by the initial population and multiply by 100:
rate of change per minute = (df/dt) / P(0) * 100% = 12.1166 / 7400 * 100% = 0.1638% (rounded to the nearest hundredth of a percent)

take-home pay to entertainment, then what
percent of his total budget will entertainment
comprise? How much money will be budgeted
towards entertainment each month?
Entertainment will comprise 90% of Ryan's total budget. The amount budgeted towards entertainment each month will be 90% of his take-home pay.
What is the frequency?The number of periods or cycles per second is called frequency. The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second.
According to the given information:Let's assume Ryan's take-home pay is P dollars.
Given that Ryan saves 10% of his take-home pay for retirement, he will save 0.10P dollars.
The remainder of his take-home pay after saving for retirement will be 90% of his take-home pay, which is 0.90P dollars.
Now, if Ryan allocates the remainder of his take-home pay to entertainment, the percentage of his total budget that entertainment will comprise can be calculated as:
Percentage of entertainment budget = (Entertainment budget / Total budget) * 100
Since the entertainment budget is 0.90P dollars and the total budget is P dollars, the percentage of his total budget that entertainment will comprise is:
Percentage of entertainment budget = (0.90P / P) * 100
Percentage of entertainment budget = 90%
So, entertainment will comprise 90% of Ryan's total budget.
The amount of money budgeted towards entertainment each month will be 0.90P dollars, which is 90% of his take-home pay.
Therefore, Entertainment will comprise 90% of Ryan's total budget. The amount budgeted towards entertainment each month will be 90% of his take-home pay.

What is the slope from -7,5 to -3,4? Please help
The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line and in the given situation the slope (m) is -1/4 respectively.
What do we mean by slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b.
M represents the line's slope.
And b is the b in the point that is the y-intercept (0, b).
For instance, the slope and y-intercept of the equation y = 3x - 7 are 3 and 0, respectively.
So, the slope formula is:
m = y₂-y₁/x₂-x₁
Now, insert values as follows:
m = y₂-y₁/x₂-x₁
m = 4-5/-3-(-7)
m = -1/-3+7
m = -1/4

The length of line segment AC is equal to 34 units.
What is the Tangent Secant Theorem?In Mathematics and Geometry, the Tangent Secant Theorem states that if a secant segment and a tangent segment are drawn to an external point outside a circle, then, the product of the length of the external segment and the secant segment's length would be equal to the square of the tangent segment's length.
By applying the Tangent Secant Theorem to this circle, we have the following:
DC² = AB × BC
15² = (3x + 1) × 9
225 = 27x + 9
27x = 225 - 9
27x = 216

1/3 of the dozen fruits in a fruit seller cart are apple. If 1/4 of all the fruits are oranges and the rest of the fruits are bananas, find how many dozen bananas are there in the fruits sellers cart
Apples make up one-third of the dozen fruits in a fruit vendor cart. If bananas make up the remaining fruit and oranges make up 1/4 of the total fruit, there are 2.5 dozen bananas in the fruit vendor's cart.
First, let's calculate how many apples are in the cart:
1/3 of 6 dozen fruits = 2 dozen fruits are apples
Next, let's calculate what proportion of the fruits are oranges:
1/4 of all fruits = (1/4) x 6 dozen = 1.5 dozen fruits are oranges
To find the number of dozen bananas, we can subtract the number of dozen apples and oranges from the total number of dozen fruits in the cart:
Total number of dozen fruits = 6 dozen
Number of dozen apples = 2 dozen
Number of dozen oranges = 1.5 dozen
Number of dozen bananas = Total number of dozen fruits - Number of dozen apples - Number of dozen orangesNumber of dozen bananas = 6 dozen - 2 dozen - 1.5 dozen
Number of dozen bananas = 2.5 dozen
Therefore, there are 2.5 dozen bananas in the fruit seller's cart.

Twenty students measure their height for an experiment in their science classroom how can a line plot help the students analyze your results
A line plot can be a useful tool for the students to analyze their results because it allows them to easily see the distribution of heights among the 20 students. By plotting each student's height as a dot above a number line, the students can quickly see how many students fall into each height range and identify any outliers or patterns in the data.
For example, if most of the dots fall within a small range of heights, the students can see that there is a cluster of heights in that range. Conversely, if there are only a few dots in a particular height range, the students can see that there is less variation in that range.
The line plot can also help the students to identify the mode, which is the most common height among the students, and the median, which is the middle height when the heights are ordered from smallest to largest. These measures of central tendency can help the students to understand the typical height of their classmates and how much variation there is in the data.
Overall, a line plot is a simple and effective way for the students to visualize and analyze their height data, and it can help them to draw meaningful conclusions about the distribution of heights among the 20 students.

One hose can fill a goldfish pond in 42 minutes, and two hoses can fill the same pond in 30 minutes. Find how long it takes the second hose
alone to fill the pond.
It takes __ minutes for the second hose alone to fill the pond.
It takes 105 minutes for the second hose alone to fill the pond.
What is an expression?An expression is a combination of numbers, variables, and mathematical operations, such as addition, subtraction, multiplication, and division, among others.
Let x be the time it takes for the second hose to fill the pond alone.
The rate at which the first hose fills the pond is 1/42 (ponds/minute).
The rate at which the second hose fills the pond is 1/x (ponds/minute).
The combined rate at which the two hoses fill the pond is 1/30 (ponds/minute).
Since they are filling the same pond, we can add their rates to get the combined rate:
⇒ 1/42 + 1/x = 1/30
To solve for x, we can simplify this equation;
⇒ 30x + 1260 = 42x
Subtracting 30x from both sides gives:
⇒ 1260 = 12x
⇒ x = 105
Therefore, it takes the second hose alone 105 minutes to fill the pond.

What is the height of the pole? (1 point)121 centimeters
220 centimeters
225 centimeters
231 centimeters
The height of the pole is 220 centimeters. We can solve it in the following manner.
We can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the legs (the sides adjacent to the right angle) is equal to the square of the length of the hypotenuse (the side opposite the right angle).
Let h be the height of the pole. Then, we have:
h² + 21² = 221²
Simplifying the right side of the equation, we get:
h² + 441 = 48841
Subtracting 441 from both sides, we get:
h² = 48400
Taking the square root of both sides, we get:
h = 220
Therefore, the height of the pole is 220 cm.

A. Investment 1: ROI = 20%, Investment 2: ROI = 18%, Investment 3: ROI = 24%. B. Select Investment 3 with the highest ROI of 24% as it generates the most return for the investment amount.
C. Investment 3 is attractive with positive residual income, but from Brown's perspective, the imputed interest charge may reduce overall profitability.
A. To calculate the ROI for each investment, we can use the following formula:
ROI = (Income / Investment) x 100%
For Investment 1: ROI = (50,000 / 250,000) x 100% = 20%
For Investment 2: ROI = (54,000 / 300,000) x 100% = 18%
For Investment 3: ROI = (96,000 / 400,000) x 100% = 24%
B. If the manager's focus is on Glengarry's divisional performance, he would select Investment 3 because it has the highest ROI of 24%. This investment generates the highest return for the amount invested, which is the primary concern for divisional performance.
C. To calculate the residual income for Investment 3, we need to subtract the imputed interest charge from its profit margin traceable to the division:
Residual Income = Profit margin traceable to the division - (Average asset investment x Imputed interest rate)
Residual Income = 96,000 - (400,000 x 22%) = 96,000 - 88,000 = 8,000
From Glengarry's perspective, Investment 3 is attractive because it generates a positive residual income of $8,000. However, from Brown's perspective, it may not be as attractive because the imputed interest charge reduces the overall profitability of the investment.

regular price is 100%, so if we take off 85% from that, that'd be 100% - 85% = 15%, so the sale price is really 15% of the regular price, well, we know regular price is $15.

Suav just started a running plan where he runs 20 miles the first week and then increases the number of miles he runs by 5% each week. If he keeps up this plan for 25 weeks, how many total miles would Suav have run, to the nearest whole number?
Suav would have run approximately [tex]$970$[/tex] miles in [tex]$25$[/tex] weeks, to the nearest whole number.
What are the whole numbers?
Whole numbers are the set of numbers that include all positive integers (1, 2, 3, ...) as well as zero (0). Whole numbers do not include any negative numbers or fractions. Therefore, the set of whole numbers is {0, 1, 2, 3, ...}.
Suav runs [tex]$20$[/tex] miles the first week. Let's use a formula to calculate the number of miles he runs in subsequent weeks. Let [tex]$m$[/tex] be the number of miles he runs in a particular week, and [tex]$w$[/tex] be the number of weeks elapsed since the first week. Then, we have:
[tex]$$m = 20 \cdot 1.05^{w-1}$$[/tex]
This formula takes into account the [tex]$5%$[/tex] increase in miles each week, starting from the initial [tex]$20$[/tex] miles in the first week.
To find the total number of miles Suav runs over [tex]$25$[/tex] weeks, we can sum up the miles he runs in each week using the formula above. That is,
[tex]$$\text{Total miles} = 20 + m_2 + m_3 + \cdots + m_{25}$$[/tex]
where [tex]$m_2, m_3, \ldots, m_{25}$[/tex] are the number of miles he runs in the second to [tex]25$th[/tex] week, respectively.
We can use the formula for [tex]$m$[/tex] to find each of these values. For example, the number of miles he runs in the second week is:
[tex]$$m_2 = 20 \cdot 1.05^{2-1} = 21$$[/tex]
Similarly, we can find the number of miles he runs in each of the other weeks:
[tex]m_3 &= 20 \cdot 1.05^{3-1} = 22.05[/tex]
[tex]m_4 &= 20 \cdot 1.05^{4-1} = 23.103[/tex]
[tex]&\vdots[/tex]
[tex]m_{25} &= 20 \cdot 1.05^{25-1} = 57.597[/tex]
Now, we can substitute these values into the formula for the total miles and simplify:
[tex]\text{Total miles} &= 20 + 21 + 22.05 + \cdots + 57.597 \&\approx 970[/tex]
Therefore, Suav would have run approximately [tex]$970$[/tex] miles in [tex]$25$[/tex] weeks, to the nearest whole number.

Answer
well if it is 5% each week, then it would be 20 +1. doing this for 25 weeks means it would be 20 + 25 then.
Sorry if wrong. i don't know if u do 5% after each time or from the main number. it doesn't say weather or not.
