Answer: 1.4 pi, and pi/180

Step-by-step explanation:

b)

this is a negative angle; It is also less than 0.5pi, (pi/2, which is the border of the first quadrant). therefore the reference angle is just the positive version:

so 1.4pi is the reference angle

c)

pi/180 is already in the first quadrant. so pi/180 would be the reference angle.

The value of x is 5.

Using Angle Sum Property

The sum of the angles in a triangle is always 180 degrees. So, we can set up an equation:

9x-1 + 62 + 74 = 180

Simplifying the equation:

9x + 135 = 180

9x = 45

x = 5

Therefore, x is 5.

Answer:

[tex]\bold{V=7048.48 ft^3}[/tex]

Step-by-step explanation:

Solution Given:

radius(r)=12

In right-angled triangle

Hypotenuse = 18

base angle =60°

Note:
In a right-angled triangle, we can use the trigonometric ratios sine, cosine, and tangent to relate the angles and sides of the triangle.
Here are the trigonometric ratios for a right-angled triangle:

Sine (sin): The sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.

[tex]\boxed{\bold{sin(A) =\frac{ opposite}{hypotenuse}}}[/tex]

Cosine (cos): The cosine of an angle is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.

[tex]\boxed{\bold{cos(A) = \frac{adjacent}{hypotenuse}}}[/tex]

Tangent (tan): The tangent of an angle is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

[tex]\boxed{\bold{tan(A) =\frac{ opposite}{adjacent}}}[/tex]

Now for the question:

Over here the relation between opposite or height and hypotenuse is given by Sine, So using this formula:

[tex]\bold{sin(60^0) =\frac{ opposite\:or\ height}{18}}[/tex]

doing criss-cross multiplication:

Sin 60°*18=opposite or height

[tex]\frac{\sqrt{3}}{2}*18[/tex] =opposite or height

opposite or height(h)=[tex]9\sqrt{3}[/tex]

Again,

We have

[tex]\boxed{\bold{Volume\:of\:cylinder= \pi * r^2 * h}}[/tex]

where:

π (pi) is a mathematical constant approximately equal to 3.14

r is the radius of the base of the cylinder

h is the height of the cylinder

Now Substituting value

[tex]Volume = \pi * r^2 * h\\Volume=3.14*12^2*9\sqrt{3}\\Volume=\bold{7048.48 ft^3}[/tex]

Step-by-step explanation:

The circumference of a circle can be calculated using the formula C = 2πr, where C is the circumference and r is the radius.

Given a radius of 2.5 meters and using an approximation of π = 3.14, we can calculate the circumference as:

The correct answer to the fraction task is 3/5 + 1/2 = 11/10 expressed as a fraction and 4/7 is incorrect answer

The pupil made an error in their addition of 3/5 and 1/2, resulting in an incorrect answer of 4/7.

To solve the task correctly, we need to find a common denominator for 3/5 and 1/2.

The least common multiple of 5 and 2 is 10, so we can rewrite the fractions with a denominator of 10 as follows:

3/5 = 6/10

1/2 = 5/10

Now we can add the fractions:

6/10 + 5/10 = 11/10

a) there are 8,535,316 ways to choose a dance committee of 8 students. b) there are 497,070 ways to choose a dance committee consisting of 2 freshmen, 2 sophomores, 2 juniors, and 2 seniors. c) there are 4,410 ways to choose a dance committee consisting of 4 juniors and 4 seniors.

a) To determine the number of ways a dance committee of 8 students can be chosen, we need to consider the total number of eligible students and choose a group of 8 from them.

Total number of eligible students = 7 freshmen + 10 sophomores + 9 juniors + 7 seniors = 33 students

The number of ways to choose a committee of 8 students from a pool of 33 is given by the combination formula:

C(33, 8) = 33! / (8!(33-8)!) = 8,535,316

Therefore, there are 8,535,316 ways to choose a dance committee of 8 students.

b) To choose a dance committee consisting of 2 freshmen, 2 sophomores, 2 juniors, and 2 seniors,

Number of ways to choose 2 freshmen from 7 freshmen = C(7, 2) = 21

Number of ways to choose 2 sophomores from 10 sophomores = C(10, 2) = 45

Number of ways to choose 2 juniors from 9 juniors = C(9, 2) = 36

Number of ways to choose 2 seniors from 7 seniors = C(7, 2) = 21

Total number of ways to choose the dance committee = 21 * 45 * 36 * 21 = 497,070

Therefore, there are 497,070 ways to choose a dance committee consisting of 2 freshmen, 2 sophomores, 2 juniors, and 2 seniors.

c) To choose a dance committee consisting of 4 juniors and 4 seniors,

Number of ways to choose 4 juniors from 9 juniors = C(9, 4) = 126

Number of ways to choose 4 seniors from 7 seniors = C(7, 4) = 35

Total number of ways to choose the dance committee = 126 * 35 = 4,410

Therefore, there are 4,410 ways to choose a dance committee consisting of 4 juniors and 4 seniors.

d) The probability of selecting a committee consisting of 2 freshmen, 2 sophomores, 2 juniors, and 2 seniors

Favorable outcomes = 497,070 (from part b)

Total possible outcomes = 8,535,316 (from part a)

Probability = Favorable outcomes / Total possible outcomes

= 497,070 / 8,535,316

Therefore, the probability of selecting a committee consisting of 2 freshmen, 2 sophomores, 2 juniors, and 2 seniors is approximately 0.058.

Answer:

OD) x = -2, -5

Step-by-step explanation:

To solve the quadratic equation x^2 + 7x + 10 = 0, we can use factoring or the quadratic formula.

Using factoring:

We need to find two numbers whose sum is 7 and whose product is 10. These numbers are 2 and 5. So, we can write x^2 + 7x + 10 = 0 as (x + 2)(x + 5) = 0.

Setting each factor to 0, we get x + 2 = 0 or x + 5 = 0. Solving for x, we get x = -2 or x = -5.

Using the quadratic formula:

The quadratic formula is x = (-b ± sqrt(b^2 - 4ac)) / 2a, where a, b, and c are the coefficients of the quadratic equation. In this case, a = 1, b = 7, and c = 10.

Substituting these values into the formula, we get x = (-7 ± sqrt(7^2 - 4(1)(10))) / 2(1)

Simplifying, we get x = (-7 ± sqrt(9)) / 2

Therefore, x = (-7 + 3) / 2 or x = (-7 - 3) / 2

Solving for x, we get x = -2 or x = -5.

Thus, the solutions of the quadratic equation x^2 + 7x + 10 = 0 are x = -2 or x = -5.

Therefore, the answer is (OD) x = -2, -5.

It can be said that  the statement that correctly compares the function shown on this graph with the function y =4x + 2 is

'The expresion indicated on the graph has a smaller rate of change, but a higher starting point.' (Option A)

We have the expression - y = mx + c, where m is the slope and

c is known as the y-intercept"

For given question,

We have been given a expresion  which states: y = 4x + 2

This function represents a line.

Looking at the above function side by side with slop-intercept form of the line.

We can state that we have slope of the line = 4 and y - intercept = 2

Note that the pace of change of the line is given by the slope.

This means that  the required pace of change of function y = 4x + 2 will be 4.

A beginning point of a function is the commencement value in a linear expression .

The beginning point of above function f(x) is 2.

The graph of the line passes via points (-1, 1) and (0, 4)

So using slope formula,

m1 = (4-1)/(0-(-1))

m1 = 3

This means that  the pace of change of function shown on the graph is 3.

This means, the pace of change of function shown on the graph is smaller than the pace of change of function y = 4x + 2

The expression of the function shown on the graph would be y = 3x + 4

The point of incetion of the function shown on the graph is 4.

This signifies that the starting point of the graphed function is higher than the starting point of the function y = 4x + 2.

As a result, the accurate statement comparing the function displayed on this graph to the function y=4x + 2 is 'The function shown on the graph has a lesser rate of change, but a higher beginning point.'

The solution to the system of equations is given as follows:

Considering the augmented matrix, the system of equations is defined as follows:

Adding the first and third equations, we have that:

-4x - 6y = -36.

From the second equation, we have that:

2x + 3y = 18.

The addition equation is a multiple of this equation, hence the system has an infinite number of solutions.

From the second equation, we have that:

2x + 3y = 18.

x + 1.5y = 9

x = 9 - 1.5y.

The definition for z is given as follows:

z = x + y - 7.

Hence the variable y is:

y = z - x + 7.

The variable x is of:

x = 9 - 1.5(z - x + 7)

x = 9 - 1.5z + 1.5x - 10.5

0.5x = 1.5 + 1.5z

Width of big solid = 6 cm = w₂

Let,
