¿Cuál de las figuras tiene ángulos agudos? A. El triángulo equilátero. B. El cuadrado. C. El pentágono regular. D. El heptágono regular.

Answers

Answer 1

Answer:

A. El triángulo equilátero.

Step-by-step explanation:

Un triángulo equilátero tiene ángulos agudos.

Los ángulos agudos tienen una medida de menos de 90 grados.

La suma de los ángulos del triángulo siempre debe ser igual a 180 grados.

Cuando 3 ángulos son iguales, la medida de cada uno de ellos vendrá dada por

3 veces = 180

x = 180/2 = 60 grados

La suma de los ángulos del cuadrado siempre es igual a 360 grados. Cuando 4 ángulos son iguales, la medida de cada uno de ellos vendrá dada por

4x = 360

x = 360/4 = 90 grados

Un cuadrado tiene cuatro ángulos rectos.

La suma de los ángulos del pentágono siempre es igual a 540 grados. Cuando 5 ángulos son iguales, la medida de cada uno de ellos vendrá dada por

5 veces = 540

x = 540/5 = 108 grados

Un pentágono regular tiene 5 ángulos obtusos.

La suma de los ángulos interiores del heptágono siempre es igual a 900 grados. Cuando 7 ángulos son iguales, la medida de cada uno de ellos vendrá dada por

7x = 900

x = 900/7 = 128,57 grados

Un heptágono regular tiene 7 ángulos obtusos.

Entonces, solo el triángulo equlateral tiene ángulos agudos.

English

An equilateral triangle has acute angles.

Acute angles are having measurement less than 90 degrees.

The  sum of angles of the triangle must always be equal to 180 degrees.

When 3 angles are equal then the measure of each of them will be given by

3x= 180

x= 180/2= 60 degrees

The  sum of angles of square always equal 360 degrees. When 4 angles are equal then the measure of each of them will be given by

4x= 360

x= 360/4= 90 degrees

A square has four right angles.

The  sum of angles of pentagon always equal 540 degrees. When 5 angles are equal then the measure of each of them will be given by

5x= 540

x= 540/5= 108 degrees

A regular pentagon has 5 obtuse angles.

The  sum of  interior angles of heptagon always equal 900 degrees. When 7 angles are equal then the measure of each of them will be given by

7x= 900

x= 900/7= 128.57 degrees

A regular heptagon has 7 obtuse angles.

So only equilateral triangle has acute angles.

How do you find the area of a isosceles triangle without the height?

Answers

Since an isosceles triangle has two equal sides, it has two equal angles and two equal heights. Therefore, if you know the length of two sides, you can use the formula A = (1/2)bh to calculate the area, where b is the length of the base and h is the length of the two equal heights.

An isosceles triangle is a triangle with two equal sides and two equal angles. Since the two equal sides also have two equal heights, we can use the formula A = (1/2)bh to calculate the area of the triangle without the height. The formula A = (1/2)bh requires the length of the base (b) and the length of the equal heights (h). Therefore, if you know the length of two sides, you can use the formula to calculate the area of the isosceles triangle without the height.

1. Determine the length of two sides of the triangle.

2. Calculate the area of the triangle using the formula A = (1/2)bh, where b is the length of the base and h is the length of the two equal heights.

3. Plug the known values into the formula and solve for the area.

He starts with 13.2 gallons of gas in his gas tank. a) Write a slope-intercept equation that models how much gas remains in his tank after each mile of of travel(hint: g/mi)

Answers

Given :

Mr. Ford's 2002 Focus would get 36 miles/gallon.

He starts with 13.2 gallons of gas in his gas tank.

To Find :

Write a slope-intercept equation that models how much gas remains in his tank after each mile of of travel(hint: g/mi).

Solution :

Let, required equation is :

y = mx + c

Here, y is gas remains in gallons.

Here, m is slope i.e. miles travelled per gallon.

So, m = -36  ( since gas is decreasing )

Initially distance travelled is 0 i.e. putting x = 0

y = c = 13.2

Therefore, y = -36x + 13.2 this is the required equation.

The function f is given by f(x)= (x-2) (x+4) . Without using graphing technology, answer the following questions.
1. What are the x-intercepts of the graph representing f?

2. What are the x- and y-coordinates of the vertex of the graph?

3. What is the y-intercept?

Answers

Answer:

Step-by-step explanation:

1. What are the x-intercepts of the graph representing f?  They are the points on the horizontal axis where the graph touches or crosses the axis.  Note that on this axis, y = 0.

2. What are the x- and y-coordinates of the vertex of the graph?  Since the function is written as the product of two binomials, we can take these coordinates directly from the binomials:  (x - 2) yields x = 2 and (x + 4) yields x = -4.

3. What is the y-intercept?   Multiply out these binomials.  We get:

f(x) = x^2 + 2 - 8.   When x = 0, y = -8.  The y-intercept is (0, -8).

1) The x-intercepts of the graph representing f are; 2 and 4

2) The x- and y-coordinates of the vertex of the graph are; (1, -5)

3) The y-intercept is at; (0, -8)

We are given the function; f(x) = (x - 2)(x + 4)

1) The x-intercepts of a graph are the points where the graph crosses the x-axis. The x-intercepts are the value of x when f(x) = 0. Thus, the x-intercepts here are 2 and 4.

2) The vertex is the lowest point of the graph in this case as the parabola opens upwards.

Let us expand the function to get;

f(x) = x² - 2x + 4x - 8

f(x) = x² + 2x - 8

where;  a = 1, b = 2, c = -8

Formula for the x-coordinate of the vertex is;

x = -b/2a

x = -2/2(1)

x = 1

Thus;

y =  (1 - 2)(1 + 4)

y = -5

x- and y-coordinates of the vertex of the graph are; (1, -5)

3) The y-intercept is the point at which x = 0. Thus;

y = 0² + 2(0) - 8

y = -8

The y-intercept is (0, -8).

How do you write an expression in vertex form?

Answers

Therefore a quadratic function can be written in vertex form as

y = a(x - h)^2 + k.

Define quadratic function.

In mathematics, a polynomial of degree two in one or more variables is referred to as a quadratic polynomial. The polynomial function that a quadratic polynomial defines is known as a quadratic function.

What is a polynomial function?

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1.

A quadratic function can be written in vertex form as y = a(x - h)^2 + k

Where (h, k) is the vertex, and a is the leading coefficient.

y = ax^2 + bx + c (standard form)

y = a(x + b/2a)^2 + c - b^2/4a

y = a(x - h)^2 + k where h = -b/2a and k = c - b^2/4a

For example,when y = 3x^2 - 6x - 5

y = 3x^2 - 6x - 5

y = 3(x^2 - 2x) - 5

y = 3(x^2 - 2x + 1 - 1) - 5 = 3(x - 1)^2 - 8

So, the equation is in vertex form y = 3(x - 1)^2 - 8

Note that this only works for parabolas that opens upwards or downwards, if the parabola opens to the sides, the vertex form is y = a(x-h)^2 +k

A designer is planning a trail mix box that is shaped like a rectangular prism. The front of the box must have the width and height shown. Volume of the box must be 162 cubic inches. What must be the depth, d, of the box?

Answers

Answer:

The box must be 2.4 in deep.

Step-by-step explanation:

Front dimensions are 9 in by 7.5 in.  Find the area of the front:  it is

A = (9 in)(7.5 in) = 67.5 in^2.  One way to complete this work would be to divide the given volume by this area, 67.5 in^2.  

A slightly different approach follows:

The volume must be 162 in^2.  Given V = (width)(height)(depth),

                                   V

(depth) must be -----------------------

                            (width)(height)

In this particular case,

                                162 in^3

(depth) must be ----------------------- = 2.4 in

                              (7.5 in)(9 in)

The box must be 2.4 in deep.

Write an explicit formula for the sequence 1,4,7,10... Then find a14.

Answers

Answer:

The formula is [tex]a_n = 3n-2[/tex]

The 14th term is 40, in other words, [tex]a_{14} = 40[/tex]

========================================================

Explanation:

The given sequence is 1, 4, 7, 10, ...

Subtract each adjacent term:

4-1 = 37-4 = 310-7 = 3

This shows that each term is increasing by 3. This is the common difference, so d = 3.

The first term is [tex]a_1 = 1[/tex]

The nth term of the arithmetic sequence is...

[tex]a_n = a_1 + d(n-1)\\\\a_n = 1 + 3(n-1)\\\\a_n = 1 + 3n-3\\\\a_n = 3n-2\\\\[/tex]

As a check, let's plug in say n = 3 to find that:

[tex]a_n = 3n-2\\\\a_3 = 3(3)-2\\\\a_3 = 9-2\\\\a_3 = 7\\\\[/tex]

The third term is 7, which matches with the sequence given to us. I'll let you confirm the other values.

-----------

We'll repeat this idea but now for n = 14 to find the 14th term of the sequence.

[tex]a_n = 3n-2\\\\a_{14} = 3(14)-2\\\\a_{14} = 42-2\\\\a_{14} = 40\\\\[/tex]

The 14th term is 40.

You can make a table of values to help confirm the answer. In the first column you'll have the values of n (1,2,3,...) all the way up to 14. The second column will consist of the sequence 1, 4, 7, 10, ... each time going up by 3 until you reach the 14th term of 40.

What is miles and foot ?

The mile is a customary unit of measurement in the United States and the United Kingdom that is based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. It is often referred to as the international mile or statute mile to distinguish it from other miles.

The British imperial and American customary systems of measurement both use the foot as a unit of length, denoted by the standard symbol: ft. An other sign that is frequently used is the prime symbol, ′. One foot is precisely equal to 0.3048 meters as of the International Yard and Pound Agreement of 1959.

5,280 feet per mile, sometimes known as a statute mile, is a unit of measurement (1.609 km). It derives from the mille passus, or "thousand paces," of the Romans, which was equivalent to 5,000 Roman feet.

65 miles per hour

so 65 * 5280 = 343200 ft travelled in 1 hr

in one minute distance travelled = 343200/60 = 5720  fts
