Triangle TUV, with vertices T(-8,2), U(-2,8), and V(-9,9), is drawn inside a rectangle, as shown below.

Answers

Answer 1

The area of triangle TUV with vertices T(-8,2), U(-2,8), and V(-9,9) are 13.4 units.

What is triangle?

A triangle is a closed two-dimensional plane figure that has three sides, three angles, and three vertices. The sum of the angles of a triangle is always 180 degrees. Triangles can be classified based on the length of their sides and the size of their angles. Some common types of triangles include equilateral, isosceles, scalene, acute, obtuse, and right triangles. Triangles are a fundamental concept in geometry and are used in many areas of mathematics and science.

Here,

To find the area of triangle TUV, we can use the formula:

Area = 1/2 * base * height

We can choose any two sides of the triangle as the base and the corresponding height. Let's choose TU as the base and the perpendicular distance from V to TU as the height.

First, let's find the length of TU:

TU = √[(8 - 2)² + (-2 - (-8))²]

= √[6² + 6²]

= 6√(2)

Next, let's find the slope of TU:

mTU = (8 - 2) / (-2 - (-8))

= -3/2

The line perpendicular to TU passing through V has a slope equal to the negative reciprocal of mTU:

mVQ = 2/3

The equation of the line passing through V and perpendicular to TU is:

y - 9 = (2/3)(x + 9)

Solving for x and y at the point where this line intersects TU, we get:

y = (2/3)x + 19

(2/3)x + 19 = -3x/2 + 7

x = -8/7

y = 94/21

The perpendicular distance from V to TU is the absolute value of y - 8:

|94/21 - 8| = 2/21

So, the area of triangle TUV is:

Area = 1/2 * TU * (2/21)

= (1/21)√(2)

To find the area of rectangle QRS, we need to find the length and width. We can use the distance formula to find the length QR and the width QS:

QR = √[(9 - (-8))² + (9 - 2)²]

= √[289]

= 17

QS = √[(9 - (-9))² + (2 - 2)²]

= √[324]

= 18

So, the area of rectangle QRS is:

Area = QR * QS

= 17 * 18

= 306

Area of triangle QRS = Area of rectangle QRS - Area of triangle TUV

= 306 - (1/21)√(2)

≈ 13.4 units

So, the answer is (C) 13.

each letter of the alphabet is written on a piece of paper and put in a hat. if a piece of paper is chosen at random, what is the probability that it will be a vowel? the number of favorable outcomes is . the number of possible outcomes is . so p(vowel)

Answers

The probability of selecting a vowel from a hat with letters of the alphabet is 5/26 or approximately 0.1923. There are 5 vowels and 26 total letters.

There are 5 vowels in the English alphabet: A, E, I, O, and U. Therefore, the number of favorable outcomes (i.e., the number of vowels in the hat) is 5.

There are a total of 26 letters in the English alphabet. Therefore, the number of possible outcomes (i.e., the number of letters in the hat) is 26.

The probability of selecting a vowel is the ratio of the number of favorable outcomes to the number of possible outcomes:

P(vowel) = number of favorable outcomes / number of possible outcomes

P(vowel) = 5 / 26

Therefore, the probability of selecting a vowel is 5/26 or approximately 0.1923 (rounded to four decimal places).

The area of the figure composing of a rectangle and a semi-circle is 105.12 ft².

What is the area of the composite figure?

The figure in the image composes of a rectangle and a semi-circle.

The area of a rectangle is expressed as;

Area = Length × Width

The area of a semi-circle is expressed as;

Area = 1/2 × πr²

First, we find the area of the rectangle.

Area = Length × Width

Plug in Length = 10ft and Width = 8ft

Area = 10ft × 8ft

Area = 80ft²

Next, find the area of the semi-circle.

Area = 1/2 × πr²

Since diameter = 8ft, radius r = diameter/2 = 8ft/2 = 4ft

Area = 1/2 × 3.14 × (4ft)²

Area = 1/2 × 3.14 × 16 ft²

Area = 25.12 ft²

Now, area of the composite figure will be:

Area of the rectangle + Area of the semi-circle.

Area = 80ft² + 25.12 ft²

Area = 105.12 ft²

Therefore, the area of the figure is 105.12 ft².

two cards are drawn without replacement from a standard deck of 52 playing cards. what is the probability at least one of them is spades

Answers

To find the probability that at least one of the two cards drawn from a standard deck of 52 playing cards is a spade, we can use the complement rule.

The complement of the event "at least one of the cards is a spade" is "neither of the cards is a spade."

The probability that the first card is not a spade is 39/52 since there are 39 non-spade cards out of a total of 52 cards. Once the first non-spade card has been drawn, there will be 51 cards remaining, of which 38 are non-spades. Thus, the probability that the second card is also not a spade is 38/51.

To find the probability that neither of the two cards is a spade, we can multiply the probabilities of drawing a non-spade on the first card and a non-spade on the second card:

P(neither is spade) = (39/52) x (38/51) = 0.4498 (rounded to four decimal places)

The probability that at least one of the two cards is a spade is equal to 1 minus the probability that neither of the cards is a spade:

P(at least one is spade) = 1 - P(neither is spade)

P(at least one is spade) = 1 - 0.4498

P(at least one is spade) = 0.5502 (rounded to four decimal places)

Therefore, the probability that at least one of the two cards drawn from a standard deck of 52 playing cards is a spade is 0.5502 or approximately 55.02%.

Answers

Answer:

  5. 3 cm × 2 cm × 7 cm

  6. f(x) = x³ -3x² -x +3

Step-by-step explanation:

You want the dimensions of a cuboid with edges marked (x-1), (x-2), and (x+3) and a volume of 42 cm³. You also want the coefficients of a monic cubic f(x) with values f(2) = -3, f(-3) = -48, and f(-1) = f(1).

5. Cuboid

The volume of the cuboid is the product of its dimensions, so we have ...

  V = LWH

  42 = (x -1)(x -2)(x +3)

The value of x can be found as the solution to this equation. A graphical solution is attached. It shows x=4, so the dimensions are ...

  4 -1 = 3

  4 -2 = 2

  4 +3 = 7

The dimensions of the cuboid are 3 cm by 2 cm by 7 cm.

Note that the prime factors of 42 are 2, 3, 7, which have the required differences. You don't really need a polynomial to guess these are the dimensions.

The expanded polynomial is x³ -7x -36 = 0, so potential rational roots will be from the set {1, 2, 3, 4, 6, 9, 12, 18, 36}. An estimate of the upper bound of the real root puts it at ∛36 +√7 ≈ 5.9. We require x > 2, so the viable choices for testing are 3 and 4. x=4 is the solution.

6. Coefficients

The remainder theorem tells you that the remainder from dividing f(x) by (x-a) is f(a). To obtain linear equations in b, c, d, we can rearrange the function to ...

  bx² +cx +d = -x³ +f(x)

For x = ±1, we know the remainders f(x) are the same, so we can look at the difference of the equations for these x-values.

  (b(-1)² +c(-1) +d) - (b(1)² +c(1) +d) = (-(-1)³ +f(-1)) - (-(1)³ +f(1))

  b -b -c -c +d -d = 1 -(-1)

  -2c = 2

We can fill in values x=2, x=-3 to get two more equations in b, c, d. The coefficients of the three equations we have for the three unknowns are shown in the second attachment. The third attachment shows the solution of these equations is (b, c, d) = (-3, -1, 3).

The table in the first attachment confirms the remainders using these coefficients.

For problem 6, we started out using synthetic division, then realized the resulting equations are the same as those developed using the rearranged form shown above. We like to let calculators and spreadsheets do the tedious arithmetic where possible.

Answer:

5)The dimensions of the rectangular prism are 3 , 7 and 2.

6) f(x) = x³ - 3x² - x + 3

Step-by-step explanation:

5) The volume of rectangular prism = l*w*h.

    l*w*h= 42

(x- 1)(x -2)(x+3) = 42

We can find (x - 2) *(x + 3) using the identity (x + a)(x + b) = x² + (a +b)*x + ab

(x - 2)(x + 3) =x² + (-2 +3)x + (-3)*2

                   = x² + 1x - 6

(x -1)(x + 3)(x - 2) = 42

(x - 1)(x² + x - 6) = 42

x*x² + x*x - 6*x + (-1)*x² + (-1) *x + (-1)(-6) = 42

x³ + x² - 6x - x² - x + 6 - 42 = 0

x³ + x² - x² - 6x - x + 6 -42 = 0

Combine the like terms,

   x³ - 7x - 36 = 0

Find the zeros of the cubic polynomial by synthetic division method.

     4       1       0      -7      -36

                      4       16       36

              1       4       9          0

x - 4 is zero of the polynomial.  

Ignore the quadratic polynomial x² + 4x  + 9 as it will have irrational roots(zeros) and dimensions will be always positive integer.

x - 4 = 0

x = 4

length =  x - 1     =  4 - 1 = 3

Width  =   x + 3 = 4 + 3 = 7

Height =  x - 2 = 4 - 2  = 2

The dimensions of the rectangular prism are 3 , 7 and 2.

6)   f(x) = x³ + bx² + cx + d

It is given that when f(x) is dived by x + 1 and x- 1, the remainders are same.

   x + 1 = 0              ; x - 1 = 0

         x = -1             ;      x = 1

                       f(-1) =  f(1)

         -1 + b -  c + d = 1 + b + c + d

-1 -1 + b - b - c - c + d - d = 0

                -2 - 2c             = 0

                                   -2c = 2

     8 + 4b + 2c + d  = -3

   8 + 4b + 2*(-1) + d = -3    {from (I)}

      8 + 4b - 2 + d    = -3

                    4b + d = -3 + 2 - 8

                     4b + d = -9 -------------(II)

It is given that when f(x) divided by ( x + 3) it leaves a remainder (-48).

                             f(-3) = -48

        -27 + 9b - 3c + d = -48

       -27 + 9b - 3*(-1) +d = -48      {From (I)}

           -27 + 9b + 3 + d  = - 48

                       9b + d     = -48 + 27 - 3

Shiloh made a scale drawing of a triangular piece of art.

Shiloh used a scale factor of 4 when making her drawing.

If the base and the height of Shiloh's drawing are 7 inches and 2 inches respectively,

what is the area of the piece of art?

Shiloh used a scale factor of 4 when making her drawing.

Therefore, the actual dimensions of the original triangular piece are four times the dimensions of the scaled drawing. Thus, the actual dimensions of the base and the height of the triangular piece are, respectively:

4 × 7 = 28 inches and 4 × 2 = 8 inches.

Using the formula for the area of a triangle,

Answers

For each increase of one unit on the x-axis (the horizontal axis), the amount on the y-axis (the vertical axis) increases by the slope of the line.

Slope is the amount of change in the y-axis that occurs as a result of a one-unit change in the x-axis. It is also known as the rise over run.

A positive slope indicates that the line rises from left to right, while a negative slope indicates that the line falls from left to right. If the slope is zero, the line is horizontal.

If the line slopes up from left to right, it has a positive slope. As the value of x increases by one, the value of y also increases by the slope. If the line slopes downward from left to right, it has a negative slope. As the value of x increases by one, the value of y decreases by the slope.

The slope of a horizontal line is zero, and the slope of a vertical line is undefined because the x or y coordinate does not change as the other changes.

Therefore, the slope of a line represents the amount by which the value on the y-axis increases for every increase of one unit on the x-axis

Find the supplementary angles formed by the line y=3x-5 and the line 4x-3y=1

Answers

Answer:

= 55.3 degrees

Step-by-step explanation:

To find the supplementary angles formed by two lines, we need to find the angles formed by each line and then subtract the sum of those angles from 180 degrees.

Let's begin by finding the slope of each line. The first line y=3x-5 is in slope-intercept form,
where the slope is the coefficient of x, which is 3.

The second line 4x-3y=1 can be rearranged to slope-intercept form by solving for y:

4x - 3y = 1
-3y = -4x + 1
y = (4/3)x - 1/3

The slope of the second line is 4/3.

Next, we can find the angle formed by each line with the x-axis using the formula:

angle = arctan(slope)

where arctan is the inverse tangent function. We can use a calculator to find the angle in degrees.

For the first line, angle = arctan(3) ≈ 71.57 degrees.

For the second line, angle = arctan(4/3) ≈ 53.13 degrees.

To find the supplementary angles, we subtract the sum of these angles from 180 degrees:

supplementary angle = 180 - (71.57 + 53.13) = 55.3 degrees.

Therefore, the supplementary angles formed by the line y=3x-5 and the line 4x-3y=1 are 55.3 degrees.

Answer:

The effect on the graph of the function f(x) = 2^x when f(x) is replaced with f(x − 3) is that it translates horizontally 3 units right.

When a function is replaced with f(x - c), where c is a positive constant, the graph of the function shifts horizontally c units to the right. Similarly, if c is negative, the graph shifts horizontally c units to the left.

Therefore, replacing f(x) with f(x - 3) in the function f(x) = 2^x shifts the graph of the function horizontally by 3 units to the right.

a. equal to xero
b. equal to one
c. negative
d. positive

Answers

The sum of the deviations of the individual data elements from their mean is always equal to zero. Correct option is A.

This is because the deviation is defined as the difference between each data point and the mean of all the data points.

Since the mean is calculated as the sum of all the data points divided by the total number of data points, the positive deviations from the mean must be balanced out by the negative deviations from the mean. In other words, for every data point that is above the mean, there is a corresponding data point that is below the mean.

When we add up all the deviations from the mean, the positive deviations will cancel out the negative deviations, resulting in a sum of zero. This property of the sum of deviations from the mean is fundamental to many statistical concepts, such as variance and standard deviation.

Therefore, the correct answer to the question is (a) equal to zero, since the sum of the deviations from the mean is always zero.

2,400,000

Answers

Answer:

1440000

Step-by-step explanation:

Since for every mile, there are 12 people, we have 120000 miles. If we multiply 12 by 120000, we get 1440000.

Answer:

Population = 1,440,000

Step by step explanation:

The population of New Mexico can be calculated by multiplying the population density (12 people/square mile) by the area of the state (120,000 square miles):

Population = Population density x Area
Population = 12 people/square mile x 120,000 square miles
Population = 1,440,000

Therefore, the population of New Mexico is 1,440,000. The correct oval to mark is "1,440,000".

Which of the following explains why it is easier to reject the null hypothesis with a one-tailed test than with a two-tailed test with all the same parameters?
a. Because the standard deviation in a one-tailed test is larger than that for a two-tailed test
b. Because z-scores are calculated differently in a one-tailed test
c. Because the critical region is all on one side in a one-tailed test and needs to be split between the two tails in a two-tailed test
d. Because a two-tailed test uses a bimodal distributio

Answers

Because the critical region is all on one side in a one-tailed test and needs to be split between the two tails in a two-tailed test.

What is the difference between a one-tailed test and a two-tailed test in hypothesis testing?

In a one-tailed test, the alternative hypothesis is directional and the critical region is all on one side of the distribution. In a two-tailed test, the alternative hypothesis is non-directional and the critical region is split between the two tails of the distribution.

Why is it easier to reject the null hypothesis with a one-tailed test than with a two-tailed test?

It is easier to reject the null hypothesis with a one-tailed test because the critical region is all on one side of the distribution, making it more likely to observe a significant difference and reject the null hypothesis. In contrast, the critical region is split between the two tails in a two-tailed test, making it less likely to observe a significant difference and reject the null hypothesis.

HELP PLEASE ¨"half-life problem¨¨ A certain computer loses half of its value every four years. If the value of the computer after 6 years is $835, what was the initial value of the computer?

Answers

Thus, the computer was initially worth $3340 as the PC will be worth $835 after six years.

what is unitary method ?

In mathematics, the unitary approach entails determining the value of a single unit in a certain circumstance and using that value to resolve other issues that are connected to it. It is a quick and efficient method for handling issues involving direct proportion, indirect proportion, and other circumstances of a same nature. In disciplines including mathematics, science, business, and engineering, the unitary technique is widely employed.

given

Let V be the computer's starting value.

The computer's value drops to V/2 after four years.

The computer's value is decreased to V/2 1/2 = V/4 after six years.

We are informed that the PC will be worth $835 after six years. When we set this equal to V/4, we obtain:

V/4 = 835

Adding 4 to both sides results in:

V = 4 × 835 = $3340

Thus, the computer was initially worth $3340 as the PC will be worth $835 after six years.

A town has a population of 12,000 and grows at 3. 5% every year. What will be the population after 7 years, to the nearest whole number?

Answers

If the population growth rate is 3.5 percent every year then the population of the town after 7 years would be 14940.

Given that population grows 3.5 percent every year.

So, the increase in population after one year

= 3.5% of 12000

= (3.5/100) × 12000

= 420

Thus the increase in population after 7 year would be,

= population increase in one year × 7

= 420×7 = 2940

Hence population of the town after 7 years = (present population + increase in population)

= 12000 + 2940

= 14940

So the population of the town after 7 years with 3.5 % growth every year would be 14490.

A hexagon with an area of 75 square inches is dilated by a scale factor of 3. What is the area of the new hexagon?

Answers

From the given information provided, the area of the new hexagon when dilated by scale factor is 675 square inches.

When a polygon is dilated by a scale factor of k, its area is multiplied by k².

A hexagon is a six-sided polygon. It is a flat shape with straight sides, and all six of its angles add up to 720 degrees.

In this case, the hexagon is being dilated by a scale factor of 3, so the area of the new hexagon will be:

Area of new hexagon = (scale factor)² x Area of original hexagon

Area of new hexagon = 3² x 75

Area of new hexagon = 9 x 75

Area of new hexagon = 675 square inches

Therefore, the area of the new hexagon is 675 square inches.

On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 5 kg weighs 25 N. Calculate the mass of another object that weighs 15 N

Answers

The weight of an object varies directly with the mass of the object therefore, the mass of the other object that weighs 15 N is 3 kg.

We can use the formula for direct variation, which states that if y varies directly with x, then y = kx, where k is the constant of variation. In this case, the weight y varies directly with the mass x, so we have:

y = kx

We are given that when x = 5 kg, y = 25 N. Substituting these values into the formula, we get:

25 = k(5)

Solving for k, we have:

k = 5

Now we can use this value of k to find the mass of another object that weighs 15 N. Let's call the mass of this object x2. We know that y2, the weight of the object, is 15 N. So we have:

15 = 5x2

Solving for x2, we have:

x2 = 3 kg

Therefore, the mass of the other object that weighs 15 N is 3 kg.
