Step-by-step explanation:

To find the measure of the central angle for the group that likes the student government program in a circle graph, we need to determine what proportion of the total number of students surveyed this group represents. We can do this by adding up the number of students who like the program and the number of students who think it is unnecessary, since these two groups represent the total number of students surveyed. Then we can divide the number of students who like the program by the total number of students surveyed and multiply by 360, which is the total number of degrees in a circle.

Total number of students surveyed = 190 + 135 + 220 = 545

Proportion of students who like the program = 190 / 545 ≈ 0.3486

So the measure of the central angle for the group that likes the program would be:

0.3486 x 360 ≈ 125

Therefore, the measure of the central angle for the group that likes the student government program would be approximately 125 degrees in a circle graph.

Step-by-step explanation: Because jasmine is enlarging the drawing, we can divide 60 and 3.75 to get how much she is enlarging. 60 divided by 3.75 is 16 meaning she is enlarging by 16. So now we multiply 16 times 2.5 to find the top and we get 40.

The expression [tex]\frac{3x^2 + 6x + 3}{x + 1}[/tex] , where x ≠ -1, is equivalent to Option (D) 3x + 3. We can factor the numerator of the expression by first factoring out the greatest common factor of 3.

What is numerator ?

In a fraction, the numerator is the top number that represents the quantity being considered.

Take 3 common from expression:

[tex]3(x^2 + 2x + 1)[/tex]

We can further factor the expression inside the parentheses using the identity [tex](x + 1)^2 = x^2 + 2x + 1[/tex] , giving:

[tex]3(x + 1)^2[/tex]

Therefore, the original expression can be written as:

[tex]\frac{3(x + 1)^2}{x + 1}[/tex]

We can simplify this expression by canceling out the (x + 1) term in the numerator and denominator, leaving us with:

[tex]3(x + 1)[/tex]

So the expression [tex]\frac{3x^2 + 6x + 3}{x + 1}[/tex] , where x ≠ -1, is equivalent to 3(x + 1). This expression represents a straight line with a slope of 3 and a y-intercept of 3.

If the original triangle has an area equal to 729 small dotty triangles. The original triangle has an area of 8 square units.

Let's first find the pattern of the number of small triangles in each row. The first row has 1 small triangle. The second row has 3 small triangles. The third row has 5 small triangles, and the fourth row has 7 small triangles. We can see that the pattern is that each row has 2 more small triangles than the previous row.

To find how many small triangles are in the third row, we add 2 to the number of small triangles in the second row:

3 + 2 = 5

So there are 5 small triangles in the third row.

To find how many small triangles are in the fourth row, we add 2 to the number of small triangles in the third row:

5 + 2 = 7

So there are 7 small triangles in the fourth row.

To find the total number of rows, we can count the number of rows from the top of the triangle to the bottom. Alternatively, we can use the formula for the sum of an arithmetic series to find the number of terms in the sequence. In this case, the first term is 1, the common difference is 2, and the last term is 7. Using the formula:

n = (last term - first term) / common difference + 1

n = (7 - 1) / 2 + 1

n = 4

So there are 4 rows in the triangle.

Finally, we can use the formula for the sum of an arithmetic series to find the total number of small triangles in the original triangle. In this case, the first term is 1, the common difference is 2, and the number of terms is 4. Using the formula:

sum = (n / 2) * (first term + last term)

sum = (4 / 2) * (1 + 7)

sum = 4 * 4

sum = 16

So there are 16 small triangles in the original triangle. Since each small triangle has an area of 1/2, the total area of the original triangle is:

area = 16 * (1/2)

area = 8

Therefore, the original triangle has an area of 8 square units.

Answer:

The correct answer you're looking for is either 85, or 68.07 (rounded)
The correct answer is if x is the hypotenuse or the most extensive length than its 85.
If x is one of the legs then 68.07 (rounded) is the correct answer.

Recommendation:

When trying to solve for a missing length you need to be sure whether it's just a leg or the hypotenuse, usually would be obvious in a picture as the sides attached to the 90º angle are usually legs and the one opposite of it is the hypotenuse.
Anywho below are the two different ways to get the answer.

Disclaimer:

There will be two answers that I will have given and I would suggest looking at the question to see which one it is, I am not only giving one possible answer. (Also very long answer, sorry!)

Note:

If messaged or commented on which numbers go on which side I'll be more than happy to confirm one answer.

Step-by-step explanation:

Figuring out only if X is Hypotenuse:

To solve for a hypotenuse you need to use the equation for the Pythagorean Theorem which states: [tex]a^{2} +b^{2}= c^{2}[/tex].

In this case, 36, and 77 are the two legs that make up this triangle.

We would insert these two numbers to replace a and b for when solving the equation.

Now you have [tex]36^{2}+ 77^{2}= c^{2}[/tex].

You then do the exponent operations for the terms that we know the values of and also add them up together to get this equation:
1296 + 5929 = 7725 or [tex]c^{2}[/tex].

After that, we'll make sure to add the terms on the first side and keep [tex]c^{2}[/tex] on the other and to also square root them giving this equation: [tex]\sqrt{7725} = \sqrt{c^{2}[/tex].

With that, your answer is 85 = X


Figuring out only if X is a Leg:

Figuring out only if X is Hypotenuse:
To solve for a leg you need to use the equation for the Pythagorean Theorem which states: [tex]c^{2}- b^{2}= a^{2}[/tex]

In this case, 36, is one of the two legs that make up this triangle while 77 is the Hypotenuse.

We would insert these two numbers to replace b and c when solving the equation.

Now you have [tex]72^{2} -36^{2} =a^{2}[/tex]

You then do the exponent operations for the terms that we know the values of and also add them up together to get this equation:
5929 - 1296 = 4633 or [tex]a^{2}[/tex]

After that, we'll make sure to subtract the terms on the first side and keep [tex]a^{2}[/tex] them on the other and also to square root them giving this equation:  
[tex]\sqrt{4633} =\sqrt{a^{2} }[/tex]

With that, your answer is 68.07 (rounded) = X

The correct inequality that represents the allowable measurements the bar can bend is | x - 4.5 | ≤ 0.1 , So correct option is E.

n mathematics, an inequality is a statement that indicates that two values are not equal. It is a relationship between two expressions that can be compared using inequality symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).

For example, 5 < 10 is an inequality that indicates that 5 is less than 10. Similarly, x + 3 ≤ 8 is an inequality that indicates that the sum of x and 3 is less than or equal to 8.

Inequalities are used to express relationships between quantities that are not necessarily equal. They can be used to represent constraints, limits, or ranges of values. Inequality statements can be combined with other mathematical expressions, such as equations or inequalities, to create more complex mathematical models.

The correct inequality that represents the allowable measurements the bar can bend is:

| x - 4.5 | ≤ 0.1

This is because the average allowable bend is 4.5 cm with a margin of error of 0.1 cm, which means that the actual allowable bend can range from 4.4 cm to 4.6 cm. The absolute value inequality represents this range of values, with the center of the range being 4.5 cm.

The permutation is a bijective function because it is both a one-one and an onto function.

A permutation of a set in mathematics is, broadly speaking, the rearrangement of its elements if the set already has an ordered structure into a sequence or linear order. Here, the components of sets are arranged in a linear or sequential order.

The bijective function is both a one-one function and an onto function.

One-one function means that for every value of the domain, there is only one value of the range. This means that an output value never repeats.

An element x is mapped to each element y by the function f known as the onto function. In other words, there is an x for every y such that:        

                                    f(x) = y

Now we have to prove why permutation is defined as bijective.

The permutation is basically an arrangement of elements.

So for the new arrangement, at one position there is only one element.

So it is one-one.

Also, we are using the given number of elements. we are just changing its positions. So every element in the co-domain is mapped to at least one element in the domain. Also, the co-domain is the range.

So it is onto function.

Therefore the permutation is a bijective function because it is both one-one and onto function.

Here,

=> h² = 2² + 3²

=> h² = 4 + 9

=> h² = 13

=> h = √(13)

Using the specification of csc, we can now determine the value of csc:

csc θ = hypotenuse / opposite

csc θ = sqrt(13) / 3

csc(θ) - csc(90° - θ) must be calculated using the identity:

csc(90° - θ) = sec θ

As a result, we have:

csc θ - csc(90° - θ) = csc θ - sec θ

= (hypotenuse / opposite) - (hypotenuse / adjacent)

= (√(13) / 3) - (√(13) / 2)

= √(13) / 6 * (2 - 3)

= -√(13) / 6
