Answers

Answer 1

the value of f(5) is 10, which is option (b) ,  the value of f(-2) is -12, which is option (d).  To find the value of f(5) using synthetic substitution, we first set up the synthetic division table as follows:

5 | 3  -9  -20

   |||___

   |   |   |

We write the coefficients of the polynomial in the top row of the table and the root (in this case, 5) outside the division symbol. We then bring down the first coefficient (3) and multiply it by the root to get 15, which we write below the second coefficient (-9). We add 15 and -9 to get 6, which we then multiply by the root to get 30, which we write below the third coefficient (-20). We add 30 and -20 to get 10, which is the remainder. Therefore, the value of f(5) is 10, which is option (b).

6) To find f(-2) using synthetic substitution, we set up the synthetic division table as follows:

-2 | 1   0   8   24

  |_|||

  |    |   |   |

We write the coefficients of the polynomial in the top row of the table and the root (in this case, -2) outside the division symbol. We then bring down the first coefficient (1) and multiply it by the root to get -2, which we write below the second coefficient (0). We add -2 and 0 to get -2, which we then multiply by the root to get 4, which we write below the third coefficient (8). We add 4 and 8 to get 12, which we then multiply by the root to get -24, which we write below the fourth coefficient (24). We add 12 and -24 to get -12, which is the remainder. Therefore, the value of f(-2) is -12, which is option (d).

Find the inverse function, f-4 (x) : f(x) = 4(3x + 2).

Answers

Answer:

To find the inverse function of f(x) = 4(3x + 2), we need to solve for x in terms of f(x) and then interchange the roles of x and f(x) in the expression to obtain the inverse function.

Let y = f(x) = 4(3x + 2)

Dividing both sides by 4, we get:

y/4 = 3x + 2

Subtracting 2 from both sides, we get:

y/4 - 2 = 3x

Dividing both sides by 3, we get:

(y/4 - 2) / 3 = x

Hence, the inverse function is:

f^-1(x) = (x/4 - 2) / 3

Or we can also write it as:

f^-1(x) = (1/3)x/4 - 2/3

Therefore, the inverse function of f(x) = 4(3x + 2) is f^-1(x) = (1/3)x/4 - 2/3.

Find the area of a segment of a circle if the central angle of the segment is 50° and the radius is 15

Answers

In conclusion the area of the segment is approximately 32.76 square units.

How to find?

To find the area of a segment of a circle, we can use the formula:

Area of segment = (θ/360)πr²2 - (1/2)rsin(θ)

where:

θ is the central angle of the segment in degrees

r is the radius of the circle

π is a constant approximately equal to 3.14

sin is the sine function

In this case, the central angle is 50° and the radius is 15. Substituting these values into the formula, we get:

Area of segment = (50/360)π(15)²2 - (1/2)(15)sin(50)

= (5/36)π(225) - (1/2)(15)(0.766)

= 32.76 square units (rounded to two decimal places)

Therefore, the area of the segment is approximately 32.76 square units.

Which car park should I use?

There is a Park and Ride service where it costs 40p per hour to park, but you also have to pay 60p for the bus fare into town.
Alternatively, I could park for free at the railway station and get the train to Mathstown - a return ticket costs £3.50.

What advice would you give me if I was trying to decide whether to use one of the car parks, the Park and Ride, or the train?

Answers

Answer:

To determine which option is the most cost-effective, you can use some simple math. Let's assume you need to park for 8 hours:

Park and Ride:

Parking cost: 8 hours x £0.40 = £3.20

Bus fare: £0.60 x 2 (round trip) = £1.20

Total cost: £4.40

Free parking at the railway station:

Train fare: £3.50 x 2 (round trip) = £7.00

Total cost: £7.00

Based on the calculations above, the Park and Ride option is cheaper for an 8-hour parking period. However, you should also consider factors such as convenience and travel time when making your decision. If the railway station is closer to your destination or has more frequent train services, it may be the better option despite the higher cost.

a reporter for an international newspaper is given an assignment that is randomly chosen from the following destinations worldwide: 8 continental united states assignments, 29 south american assignments, 15 european union assignments, and 22 asian assignments. find the probability that he gets an assignment in the united states or asia . express your answer as a fraction

Answers

The probability that the reporter gets an assignment in the United States or Asia is 15/37.

To find the probability that the reporter gets an assignment in the United States or Asia, we first need to determine the total number of assignments in the pool.

Total number of assignments = 8 + 29 + 15 + 22 = 74

Next, we need to determine the number of assignments that are in the United States or Asia.

Number of assignments in the United States or Asia = 8 + 22 = 30

Finally, we can calculate the probability of the reporter getting an assignment in the United States or Asia by dividing the number of assignments in the United States or Asia by the total number of assignments:

Probability of getting an assignment in the United States or Asia = (Number of assignments in the United States or Asia) / (Total number of assignments)

Probability of getting an assignment in the United States or Asia = 30/74

Therefore, the probability of the reporter getting an assignment in the United States or Asia is 30/74, which can be simplified by dividing both the numerator and denominator by their greatest common factor (GCF), which in this case is 2:

Probability of getting an assignment in the United States or Asia = 15/37

Answers

Answer:

(4,2) represents the number of ways to choose 2 items from a set of 4 distinct items. The formula for C(n,r) is n! / (r! * (n-r)!), where n is the total number of items and r is the number of items being chosen. Plugging in the values for C(4,2), we get: C(4,2) = 4! / (2! * (4-2)!) = 24 / (2 * 2) = 6 Therefore, there are 6 ways to choose 2 items from a set of 4 distinct items.

0 / 350

The value of the given combination C(4, 2) by applying the combination formula in factorial form is equals to option 6.

To evaluate C(4, 2), we use the combination formula, also known as "n choose r" or "C(n, r)",

which calculates the number of ways to choose r items from a set of n distinct items without considering their order. The formula for C(n, r) is:

C(n, r) = n! / (r! × (n - r)!)

Where "!" denotes the factorial of a number, which is the product of all positive integers up to that number.

For example,

4! = 4 × 3 ×2 × 1

   = 24.

Now, let's plug the values into the formula for C(4, 2):

C(4, 2) = 4! / (2! × (4 - 2)!)

= 4! / (2! × 2!)

= (4 × 3 × 2 × 1) / ((2 × 1) × (2 × 1))

= (24) / (4)

= 6

Therefore , the value of the combination C(4, 2) equals  to option 6.

The geese population at Whitney National Park was 450 in 1999. If it increased by 24% within a one year period, what was the geese population at Whitney National Park in 2000?

Answers

Answer:

558

Step-by-step explanation:

To find the geese population at Whitney National Park in 2000, we need to add 24% of the population in 1999 to the population in 1999.

First, we need to calculate 24% of 450:

24% of 450 = 0.24 x 450 = 108

So the increase in the geese population from 1999 to 2000 is 108.

To find the population in 2000, we need to add this increase to the population in 1999:

Population in 2000 = Population in 1999 + Increase

Population in 2000 = 450 + 108

Population in 2000 = 558

Therefore, the geese population at Whitney National Park in 2000 was 558.

If the measure of angle 11 is 90 degrees, and the measure of angle 9 is 60 degrees, what is the measure of angle 10?

Answers

The measure of angle 10 is 30 degrees.

What is an angle?

we can see that angle 10 and angle 11 form a straight line, and angle 9 and angle 10 form a triangle with angle 11.

Since angle 11 is a right angle with a measure of 90 degrees, the sum of angles 9 and 10 in the triangle must be 90 degrees.

We know that the measure of angle 9 is 60 degrees, so we can solve for the measure of angle 10 as follows:

angle 9 + angle 10 = 90 degrees

60 degrees + angle 10 = 90 degrees

angle 10 = 90 degrees - 60 degrees

angle 10 = 30 degrees

Therefore, the measure of angle 10 is 30 degrees.

Step-By-Step:

The height triangle has a height of 17.3 yards and a width of 12 yards. 3. Finally, connect the two triangles to create the pyramid's surface area. The surface area of the pyramid is 116.7 yards².

Answer:

116.7 yards².

Answer:

The first step is to find the area of the base triangle:

Area = (1/2) x base x height

Area = (1/2) x 20 yards x 17.3 yards

Area = 173 square yards

To find the surface area of the pyramid, we need to find the areas of the four triangular faces and add them to the base area.

Area of a triangular face = (1/2) x base x height

Area of each face = (1/2) x 20 yards x 12 yards

Area of each face = 120 square yards

Now we can add up all the areas:

Surface area = base area + area of four faces

Surface area = 173 square yards + 4 x 120 square yards

Surface area = 653 square yards

Therefore, the surface area of the pyramid is 653 square yards.

Find the value of < Z O X


< Z O X = °

Answers

The unknown angles on the straight line is as follows:

∠ZOX = 64 degrees

How to find the angles on a straight line?

The sum of angles in a line segment is 180 degrees. Therefore, let's find the angle ∠ZOX as follows:

∠YOX = ∠YOZ + ∠ZOX

Therefore,

∠ZOX = ∠YOX -  ∠YOZ

∠YOX = 180°

Therefore,

5x + 6 + 3x - 2 = 180

8x + 4 = 180

8x = 180 - 4

8x = 176

x = 176 / 8

x = 22

Hence,

∠ZOX = 3x - 2

∠ZOX = 3(22) - 2

∠ZOX = 66 - 2

∠ZOX = 64 degrees

What is law of cosine?

According to a trigonometry rule, the square of a side in a plane triangle is equal to the total of the squares of the other sides minus twice that amount, along with the cosine of the angle that separates them.

Here using law of cosine we can find the distance between Bert and Ernie. Then,

[tex]a^2=b^2+c^2-2ab cos(A)[/tex]

Here a = BC , b = 5 mi , c = 6.5 mi and A = 100° then,

=> [tex]BC^2 = 5^2+6.5^2-2\times5\times6.5\times cos (100\textdegree)[/tex]

=> [tex]BC ^2= 25+42.25-65\times(0.1736)[/tex]

=> [tex]BC^2= 78.534[/tex]

=> BC = 8.8 miles.

Hence the distance between Bert and Ernie is 8.8 miles.

what is the equation for a cosecant function with vertical asymptotes found at such that n is an integer?

Answers

The equation for a cosecant function with vertical asymptotes found at x = nπ such that n is an integer is `y = csc(x - nπ)`.

The cosecant function is the reciprocal of the sine function. The cosecant of a particular angle in a right triangle is the ratio of the hypotenuse to the side opposite the angle.

The cosecant function is written as follows: `csc(x) = 1/sin(x)`

Asymptotes are straight lines or curves that a graph approaches but never touches.

As a result, the graph of a curve gets closer and closer to the asymptote as it moves further away from the origin, but it never touches it.

For a function to have vertical asymptotes at `x = nπ`, the denominator of the function should equal zero. In the cosecant function, the denominator is equal to `sin(x - nπ)`.

Therefore, the vertical asymptotes are where `sin(x - nπ) = 0`.

The general form of the cosecant function is `y = A csc(B(x - C)) + D`.

The constants A, B, C, and D are used to alter the form of the graph of the cosecant function.

They can be used to alter the amplitude, period, phase shift, and vertical displacement of the graph, respectively.

A. True
B. False

please help me!!

Answers

(1)  The scale factor for this dilation is 1/6.

(2) The scale factor for this dilation is 6.

(3) False. A dilation with a scale factor less than 1 is a reduction, not an enlargement.

What is the scale factor?

1. To find the scale factor for the dilation with center at the origin that maps point M(-12,18) to M(-2,3) we can use the formula:

new coordinate / old coordinate = scale factor

For the x-coordinate:

-2 / -12 = 1/6

For the y-coordinate:

3 / 18 = 1/6

Since both coordinates have the same scale factor, we can conclude that the scale factor for this dilation is 1/6.

2. To find the scale factor for the dilation with center at the origin that maps point M(-2,3) to M'(-12,18) we can again use the formula:

new coordinate / old coordinate = scale factor

For the x-coordinate:

-12 / -2 = 6

For the y-coordinate:

18 / 3 = 6

Since both coordinates have the same scale factor, we can conclude that the scale factor for this dilation is 6.

3. False. A dilation with a scale factor less than 1 is a reduction, not an enlargement. An enlargement is a dilation with a scale factor greater than 1.

In a class of 40 students each student take at least One of Physics and Chemistry. If the number of student that take Physics is three times the number that take both Subsect and the number that take chemistry is twice the number that take Physic, find the number of Student that take Physics only​

Answers

the number of students who take only Physics is 15.

Define equation

An equation is a mathematical statement that shows that two expressions are equal. It is typically written using an equal sign (=) between the two expressions. The expressions on either side of the equal sign are called the left-hand side (LHS) and the right-hand side (RHS) of the equation.

Let's denote the number of students who take only Physics by x.

The total number of students who take Physics or Chemistry=40The number of Physics students is three times the number who take both: number of Physics students = 3The number of Chemistry students is twice the number who take Physics: number of Chemistry students = 2

We can use these equations to solve for x, the number of students who take only Physics:

40 = 3(number who take both) + 2(number of Physics students) - number who take both40 = 2(number who take both) + 2(number of Physics students)20 = number who take both + number of Physics students

Substituting the expression for the number of Physics students in terms of the number who take both, we get:

20 = number who take both + 3(number who take both)

20 = 4(number who take both)

number who take both = 5

this value in the expression for the number of Physics students, we get:

number of Physics students = 3(number who take both) = 15

Finally, we can use the first equation to solve for the number of students who take only Physics:

40 = 15 + 2(number of students who take only Physics) - 5

40 = 10 + 2(number of students who take only Physics)

number of students who take only Physics = 15

Therefore, the number of students who take only Physics is 15.
