I need in 5 min!! Please hurry !! An isosceles trapezoid has a perimeter of 32 meters. Its shorter base measures 4 meters and its longer base measures 6 meters. The two remaining sides have the same length; what is that length?

Answers

The length of each of the remaining sides of the isosceles trapezoid is 11 meters.

Let's denote the length of the remaining sides of the isosceles trapezoid as "x" meters each.

The perimeter of the trapezoid is the sum of all its side lengths. In this case, we have:

Shorter base + Longer base + Side 1 + Side 2 = Perimeter

Plugging in the given values:

4 + 6 + x + x = 32

Simplifying the equation:

10 + 2x = 32

Subtracting 10 from both sides:

2x = 22

Dividing both sides by 2:

x = 11

Therefore, the length of each of the remaining sides of the isosceles trapezoid is 11 meters.

The answer is DDDDDDDDDD

Determine the open intervals on which the function is increasing, decreasing, or constant. (Enter your answers using interval notation.)

…………..t + 2, t<0
F(t) =….2, 0 ≤ t ≤ 2
………….-t + 4, t > 2

increasing: ____________
decreasing: ___________
constant: ______________

Answers

Based on the analysis, we can summarize the intervals as follows:

Increasing: (-∞, 0)

Decreasing: (2, ∞)

Constant: [0, 2]

To determine the intervals on which the function is increasing, decreasing, or constant, we need to analyze the behavior of the function in each interval.

For the given function:

F(t) =

t + 2, t < 0

2, 0 ≤ t ≤ 2

-t + 4, t > 2

Let's consider each interval separately:

For t < 0:

In this interval, the function F(t) = t + 2 is a linear function with a positive slope. As t decreases, the function value increases.

Therefore, the function is increasing on the interval (-∞, 0).

For 0 ≤ t ≤ 2:

In this interval, the function F(t) is constant, as it is defined as F(t) = 2. The function value remains the same regardless of the value of t.

Therefore, the function is constant on the interval [0, 2].

For t > 2:

In this interval, the function F(t) = -t + 4 is a linear function with a negative slope. As t increases, the function value decreases.

Therefore, the function is decreasing on the interval (2, ∞).

To map Figure T to Figure U, we can use the following sequence of transformations:

Translation: Move the figure 10 units to the right and 12 units down.

This will shift all the points in Figure T by the specified distances.

Reflection: Reflect the figure across the vertical axis.

This will reverse the order of the points horizontally.

Translation: Move the figure 5 units to the right and 10 units up.

This will shift all the points in Figure T (which is now reflected) by the specified distances.

The resulting sequence of transformations would be:

Translation (10 units right, 12 units down) -> Reflection (across the vertical axis) -> Translation (5 units right, 10 units up)

Applying these transformations to Figure T should result in Figure U.

It is essential for a table to meet both criteria to represent a valid function.

Based on the given information, it appears that the table in question does not represent a function. This is because a function requires each element in the domain to be associated with exactly one element in the range (Statement B).

If any element in the domain has more than one corresponding element in the range, it violates the definition of a function.

Additionally, the table fails to show a function because each output does not have exactly one input (Statement D). In a true function, every output value should be associated with only one input value. If any output has multiple inputs, it indicates that the table is not a function.

2.2 C Calculate the value of x if the product of x + 3 and 2x + 3 is 14 more then the product of x + 1 and 2x + 1.​

Answers

Answer:

x = 1

Step-by-step explanation:

To solve the given equation, we'll start by setting up the equation and simplifying it step by step:

The product of (x + 3) and (2x + 3) is 14 more than the product of (x + 1) and (2x + 1).

(x + 3)(2x + 3) = (x + 1)(2x + 1) + 14

Expanding both sides of the equation:

2x^2 + 3x + 6x + 9 = 2x^2 + x + 2x + 1 + 14

Combining like terms:

2x^2 + 9x + 9 = 2x^2 + 3x + 15

Subtracting (2x^2 + 3x + 15) from both sides:

2x^2 + 9x + 9 - 2x^2 - 3x - 15 = 0

Simplifying:

6x - 6 = 0

Adding 6 to both sides:

6x = 6

Dividing both sides by 6:

x = 1

Therefore, the value of x that satisfies the equation is x = 1.

Triangle ABC with vertices at A(-1,-1), B(1,1), C(0,1) is dilated to create triangle A’B’C with vertices at A’(-3,-3), B’(3,3), C’(0,3) determine the scale factor used.

A. 1
B. 1/2
C. 3
D. 1/3

Answers

The scale factor used in the dilation is 3.

First, the distance between points A and B in triangle ABC is:

AB = √[(x₂ - x₁)² + (y₂ - y₁)²]

AB = √[(1 - (-1))² + (1 - (-1))²]

AB = √[(2)² + (2)²]

AB = √[4 + 4]

AB = √8

The distance between points A' and B' in triangle A'B'C' is:

A'B' = √[(x₂' - x₁')² + (y₂' - y₁')²]

A'B' = √[(3 - (-3))² + (3 - (-3))²]

A'B' = √[(6)² + (6)²]

A'B' = √[36 + 36]

A'B' = √72

The scale factor can be determined by dividing the corresponding side lengths:

Scale factor = A'B' / AB

Scale factor = √72 / √8

Scale factor = (√(72/8))

Scale factor = √9

Scale factor = 3

Answers

The perimeter of a rectangle with a length of Eight and one-sixth feet and a width of Six and two-thirds feet is  twenty-nine and four-sixths

The length of the rectangle is [tex]8\frac{1}{6}[/tex] feet, which can be written as a mixed number: 8 + 1/6 = 49/6 feet.

The width of the rectangle is [tex]6\frac{2}{3}[/tex]  feet, which can also be written as a mixed number: 6 + 2/3 = 6 2/3 = 20/3 feet.

To find the perimeter, we add twice the length and twice the width:

Perimeter = 2(length) + 2(width)

Perimeter = 2(49/6) + 2(20/3)

Perimeter = (98/6) + (40/3)

Perimeter = 98/6 + 80/6

Perimeter = 178/6

To simplify the fraction, we can divide the numerator and denominator by their greatest common divisor, which is 2:

Perimeter = (178/6) ÷ 2

Perimeter = 89/3

So, the perimeter of the rectangle is 89/3 feet. To express it as a mixed number:

Perimeter =[tex]29\frac{2}{3}[/tex] feet

The critical value, given the sample size of 5 and the confidence level of 99. 0 percent would be 16. 812.

How to find the critical value ?

The critical values for the chi-squared (χ^2) distribution depend on the degree of freedom and the level of significance.

The degree of freedom for a chi-squared distribution typically equals the sample size minus 1 so the degrees of freedom here is:

Step-by-step explanation:

To find the selling price of a car that is sold at a loss of 14% on the cost price, we can follow these steps:

Calculate the amount of the loss:

Loss = 14% of the cost price

Loss = 14/100 * $177,000

Subtract the loss from the cost price to find the selling price:

Selling Price = Cost Price - Loss

Selling Price = $177,000 - (14/100 * $177,000)

Simplify the expression:

Selling Price = $177,000 - ($24,780)

The angle of inclination from the base of skyscraper A to the top of skyscraper B is approximately 10.5°. If skyscraper B is 1463 feet​ tall, how far apart are the two​ skyscrapers? Assume the bases of the two buildings are at the same elevation.

Answers

The two Skyscrapers are approximately 7670.51 feet apart.

The distance between the two skyscrapers, we can use trigonometry and the given information about the angle of inclination and the height of skyscraper B. Let's break down the problem step by step.

1. Let's denote the distance between the bases of the two skyscrapers as d.

2. We can visualize the situation as a right triangle, where the height of skyscraper B (1463 feet) represents the opposite side and the distance between the two buildings (d) represents the adjacent side. The angle of inclination (10.5°) is the angle between the adjacent side and the hypotenuse.

3. The trigonometric function that relates the opposite side, adjacent side, and the angle of inclination is the tangent (tan) function: tan(angle) = opposite/adjacent.

4. Plugging in the known values, we have tan(10.5°) = 1463/d.

5. To solve for d, we can rearrange the equation: d = 1463 / tan(10.5°).

6. Evaluating the tangent of 10.5° using a calculator, we find that tan(10.5°) is approximately 0.1908.

7. Now, substituting this value into the equation, we have d = 1463 / 0.1908.

Answers

the answer is B, 5 weeks.

Answer:

5 weeks

Step-by-step explanation:

the two linear equations are:

sibling (A)      and  sibling (B)

y = 10x + 25   and y = 5x + 50

where y = mx + c

and x represents the number of weeks

after how many weeks will their savings accounts have the same amount of money i.e. for which value of x will both equations have the same value

inserting the value of x in both equations:

for x = 2.5  A = 50 and B = 62.5

for x = 5     A = 75  and B = 75

for x = 15    A = 175 and B = 125

for x = 75   A = 775 and B = 425

thus, after 5 weeks both siblings A and B will have the same amount of money in their accounts

The value of x (the perpendicular side) in the given triangle is 6√5 cm.

Let's denote the length of the perpendicular side as x.

Given that the hypotenuse is 14 cm and the base is 4 cm.

As per the Pythagoras's theorem, we can set up the equation:

x² + 4² = 14²

x² + 16 = 196

To solve for x, we subtract 16 from both sides of the equation:

x² = 180

Taking the square root of both sides, we get:

x = √180

Answers

I) 1. The slope (m) of a line is 150.

2. The equation of the line is y = 150x.

II) 1. The slope (m) of a line is 100.

2. The equation of the line is y = 100x.

To estimate the line of best fit using the given points (1, 150) and (6, 900), we can follow these steps:

1. The slope (m) of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:

m = (900 - 150) / (6 - 1)

m = 750 / 5

m = 150

2. We can use the point-slope form of a linear equation to write the equation of the line:

y - y₁ = m(x - x₁)

So, y - 150 = 150(x - 1)

y - 150 = 150x - 150

y = 150x

So, the equation of the line is y = 150x.

3. The slope of the line represents the change in y (sales) for each unit increase in x (TV ads). In this case, the slope is 150, which means that for every TV ad, CD sales increase by about 150 units.

Similarly, using the points (1, 100) and (8, 800) to estimate the line of best fit:

II) 1. the slope of the line:

m = (800 - 100) / (8 - 1)

m = 700 / 7

m = 100

and, the equation of the line:

y - 100 = 100(x - 1)

y - 100 = 100x - 100

y = 100x

So, the equation of the line is y = 100x.

and, the slope of the line represents the change in y (sales) for each unit increase in x (magazine ads). In this case, the slope is 100, which means that for every magazine ad, CD sales increase by about 100 units.

What is the domain of this radical function?
f(x)= root of x+1 -3

Answers

Answer:

The domain of a radical function is the set of all real numbers for which the function is defined. In this case, we have the function f(x) = √(x + 1) - 3.

For the function to be defined, the value inside the square root (√) must be non-negative, since the square root of a negative number is undefined in the real number system.

So, to determine the domain, we set the expression inside the square root greater than or equal to zero:

x + 1 ≥ 0

Solving for x:

x ≥ -1

Therefore, the domain of the given radical function is all real numbers greater than or equal to -1. In interval notation, the domain can be expressed as (-1, +∞).

-x squared +12x+14 and 2x+30 solve this system of equations

Answers

The value of x from equation 2 doesn't satisfy equation 1. Thus, there is no solution for this system of equations, meaning the given equations are inconsistent.

To solve the given system of equations, we have:

1) -x^2 + 12x + 14 = 0
2) 2x + 30 = 0

First, solve equation 2 for x:
2x = -30
x = -15

Now, substitute the value of x in equation 1:
-(-15)^2 + 12(-15) + 14 = 0
-225 - 180 + 14 = 0
-391 ≠ 0

Answer the question please

Answers

the stargazer is 24 miles away from the center of the city.

reasoning:
in order to solve the equation, you have to substitute 71 for y. you then get an equation that looks like this:

71 = 2.75x + 5

now we have to get rid of the +5. what you do to one side of the equation, you have to do to the other. SUBTRACT 5 from both sides. you now have:

66 = 2.75x

now you have to isolate the variable (the x). in order to do that, you have to DIVIDE both sides by 2.75, since that is the number that is attached to the variable. you are now left with:

24 = x

which is the answer to the equation because x represents the number of miles away from the center of the city the stargazer is.

PLEASE HELP ME. Which of the following number sentences is an example of the associative property of multiplication?

4 × 5 = 5 × 4
6 × 1 = 6
20 × (10 + 6) = (20 × 10) + (20 × 6)
(12 × 3) × 8 = 12 (3 × 8)

Answers

Answer:

(12 × 3) × 8 = 12 × (3 × 8)

Step-by-step explanation:

The associative property of multiplication states that the way in which factors are grouped in a multiplication expression does not change the product. In other words, if we have three or more numbers to multiply, it doesn't matter which order we multiply them in.

Out of the given number sentences, the example of the associative property of multiplication is:

(12 × 3) × 8 = 12 × (3 × 8)

This is because we can group the factors in either of the two ways and get the same product.

Hope this helps!
