Answers

Answer 1

The area of the shaded region is  73.4 cm².

What is Area ?

An object's area is the space that its boundary encloses. A closed figure's area is determined by how many unit squares are present on its surface.

Given : Radius of circle = 5 cm

The area of circle = πr²

                             = 25π = 78.57 cm²

Now, the area of segment can be found by using the formula :

                 = 1/2 × r² × [ πФ/180 - sinФ]

So, area of segment = 1/2 × 25 × [ π×80/180 - Sin 80 ]

                                  = 25/2 × [4π/9 - 0.9848 ]

                                  = 25/2 × [1.3968 - 0.9848]

                                  = 5.15 cm² approx.

So, Th area of shaded region = area of circle - area of segment

                                                  = 78.57 - 5.15

                                                 = 73.4 cm²

Step-by-step explanation:

Hello There!

Remember this is the triangle angle rule:

The angles of a triangle MUST have a sum of 180

That being said we can find the missing angle by subtracting the given angles ( 87 and 32 in this case) from 180

so missing angle = 180 - 87 - 32

180 - 87 = 93

93 - 32 = 61

so we can conclude that the answer is c

In this exercise we have to observe the graph informing and in this way identify the best alternative that represents this question, so we have to:

Letter B

So to start, we have to look at the graph axes separately, being the X axis first, then:

When we look at the area demarcated on the X axis, we realize that it is only about negative values, so X will always be less than zero.Now looking at the Y axis, we can see that it will always be values ​​greater than or equal to -1.

Thus, the alternative is found in the letter B, since:

The diameter of a circle with an area of 1,808.64 square meters, rounded to the nearest meter.

What is the diameter of the circle?

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.

What is Inequality?

Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given:

According to the question, we have the Expression

(x-1 )/ (1-x) < 0

Because the function exists, the denominator is not equal to zero. That is, x does not equal 1. Because the denominator is zero when x = 1 and the function is not defined.

Thus, in the solution set of (x-1 )/ (1-x) < 0  excluding one, at every real number is function is defined.

Therefore, the correct option is C shows the solution set.

3. What is the axis of symmetry of the graph of function f(x) = x² - 6x – 1

Answers

Answer:

guihnijiop;kl;lkm

Step-by-step explanation:

Answer:

A parabola has an axis of symmetry at x = 3 if the x-value of the vertex is 3.

f(x) = x^2 + 3x + 1 = x^2 + 3x + 9/4 - 5/4 = (x + 3/2)^2 - 5/4 => vertex = (-3/2, -5/4)

f(x) = x^2 - 3x - 3 = x^2 - 3x + 9/4 - 21/4 = (x - 3/2)^2 - 21/4 => vertex = (3/2, -21/4)

f(x) = x^2 + 6x + 3 = x^2 + 6x + 9 - 6 = (x + 3)^2 - 6 => vertex = (-3, -6)

f(x) = x^2 - 6x - 1 = x^2 - 6x + 9 - 10 = (x - 3)^2 - 10 => vertex = (3, -10)

Therefore, f(x) = x^2 - 6x - 1 has an axis of symmetry at x = 3.

A) False ; R^2 is not a two dimensional subspace of R^3 because Vector R^2 will have 2 entries while vector R^3 has 3 entries

B) False : The number of variable in the equation is not equal to the Dimension because dim of Null A represents the number of free variables

C) False : This is because you can span R^3 with an infinite set of vectors but that doesn't make it infinite dimensional subspace

D) False : This is only possible when S has exactly n elements/vectors

E) True : Since R^3 is a three dimensional subspace it is spanned with 3 vectors whom are linearly independent

I invite each of you to sit down in front of your television set when your station goes on the air and stay there, for a day, without a book, without a magazine, without a newspaper, without a profit and loss sheet or a rating book to distract you. Keep your eyes glued to that set until the station signs off. I can assure you that what you will observe is a vast wasteland.[2] You will see a procession of game shows, formula comedies about totally unbelievable families, blood and thunder, mayhem, violence, sadism, murder, western bad men, western good men, private eyes, gangsters, more violence, and cartoons. And endlessly, commercialsmany screaming, cajoling, and offending. And most of all, boredom. True, you'll see a few things you will enjoy. But they will be very, very few. And if you think I exaggerate, I only ask you to try it.[3] Is there one person in this room who claims that broadcasting can't do better? Well a glance at next season's proposed programming can give us little heart. Of 73 and 1/2 hours of prime evening time, the networks have tentatively scheduled 59 hours of categories of action-adventure, situation comedy, variety, quiz, and movies. Is there one network president in this room who claims he can't do better?[4] The best estimates indicate that during the hours of 5 to 6 P.M. sixty percent of your audience is composed of children under twelve. And most young children today, believe it or not, spend as much time watching television as they do in the schoolroom. I repeatlet that sink in, ladies and gentlemenmost young children today spend as much time watching television as they do in the schoolroom. It used to be said that there were three great influences on a child: home, school, and church. Today, there is a fourth great influence, and you ladies and gentlemen in this room control it.[5] If parents, teachers, and ministers conducted their responsibilities by following the ratings, children would have a steady diet of ice cream, school holidays, and no Sunday school. What about your responsibilities? Is there no room on television to teach, to inform, to uplift, to stretch, to enlarge the capacities of our children? Is there no room for programs deepening their understanding of children in other lands? There are some fine children's shows, but they are drowned out in the massive doses of cartoons, violence, and more violence. Must these be your trademarks? Search your consciences and see if you cannot offer more to your young beneficiaries whose future you guide so many hours each and every day [6] You must provide a wider range of choices, more diversity, more alternatives. It is not enough to cater to the nation's whims; you must also serve the nation's needs. And I would add this: that if some of you persist in a relentless search for the highest rating and the lowest common denominator, you may very well lose your audience.
