Softa [21]

Para redondear este número a 1,000, verifiquemos el tercer dígito del número.

Si el dígito es mayor que 5, aumentamos el siguiente número en 1 unidad.

Si el dígito es menor o igual a 5, mantenemos el siguiente número.

El tercer dígito es 3, por lo que el número redondeado es:

19/100+7/10 wich fraction can be used in place of 7/10 to find the value of the expression​
Dimas [21]

Answer:

70/100.

Step-by-step explanation:

When adding fractions, you need to find a common denominator.

This just means that the numbers at the bottom of both fractions you are adding must be the same.

So for 19/100 + 1/10, you need to match the two denominators (bottom numbers).

To do this, you need to multiply 10 by 10 to get 100.

What you do to the bottom, you must always do to the top as well.

So multiply 7 by 10 and get 70.

70/100 will replace 7/10.

Now you can add fractions because the bottom numbers are the same.

Y = – 2x² + 12x - 7
Vikentia [17]

Answer:

a) axis of symmetry: <em> </em><em>x</em> = <em>h</em>

b) Vertex: (3, 11).

c/d) Maximum point = vertex (3, 11).

Step-by-step explanation:

<em><u>Note:</u></em><em> </em>This post will only provide the answers for parts a through d, in accordance with Brainly's Guidelines.

Given the quadratic equation, y = – 2x² + 12x - 7, where a = -2, b = 12, and c = -7:

<h3>  </h3><h3>a) What is equation of the axis of symmetry?</h3>

The <u>axis of symmetry</u> is an imaginary line that divides the graph of a parabola into two symmetrical parts.  The axis of symmetry goes through the x-coordinate of the vertex, (<em>h</em>, k). Hence, the axis of symmetry is often represented by the following equation: x = h.  

<h3 /><h3>b) What is the vertex?</h3>

We can find the x-coordinate of the vertex by using the following formula:

\displaystyle\mathsf{x\:=\:\frac{-b}{2a}}

Substitute the given values for a = -2, and b = 12 into the formula:

\displaystyle\mathsf{x\:=\:\frac{-(12)}{2(-2)}\:=\:\frac{-12}{-4}\:=\:3}

Hence, the x-coordinate of the vertex is 3.  

Substitute x = 3 into the given quadratic equation to find its corresponding y-coordinate:

y = – 2x² + 12x – 7

y = – 2(3)² + 12(3) – 7

y = –2(9) + 36 – 7

y = – 18 + 36 – 7

y = 11

Therefore, the <u>vertex</u> of the given quadratic equation is (3, 11).

<h3 /><h3>c/d) Does the equation have a maximum or minimum? What is the maximum/minimum?</h3>

The value of the "<em>a</em>" coefficient in the quadratic equation, y = <u>a</u>x² + bx + c, determines whether a given parabola has either a minimum, or a maximum.

  • If <em>a</em> > 1, then it means that the graph of a parabola opens <u>upward</u>, and the vertex is its <u><em>minimum</em></u> point.
  • If <em>a</em> < 0, then the graph of a parabola opens downward, and the vertex is its <u><em>maximum</em></u> point.  

Since the value of our given quadratic equation is a = -2, then it means that its graph opens <em>downward</em>, and that the <u>vertex is its maximum point</u>.  

Attached is a screenshot of the graph, where it shows the vertex occurring at point (3, 11), for which the axis of symmetry goes through at x = 3.
