\bf \textit{equation of a circle}\\\\ 
(x- h)^2+(y- k)^2= r^2
\qquad 
center~~(\stackrel{-2}{ h},\stackrel{5}{ k})\qquad \qquad 
radius=\stackrel{4}{ r}
\\\\\\\
[x-(-2)]^2+[y-5]^2=4^2\implies (x+2)^2+(y-5)^2=16

If quadrilateral PQRS is a kite, which statements must be true? Check all that apply.
mel-nik [20]

A kite is a quadrilateral in which two disjoint pairs of consecutive sides are congruent (“disjoint pairs” means that one side can’t be used in both pairs).

Then:

  • Two disjoint pairs of consecutive sides are congruent by definition - QP≅QR and QR is not congruent to RS (one side can’t be used in both pairs);
  • One diagonal (segment QS, the main diagonal) is the perpendicular bisector of the other diagonal (segment PR, the cross diagonal), so PM≅MR;
  • The opposite angles at the endpoints of the cross diagonal are congruent, thus ∠QPS≅∠QRS.
  • ∠PQR is not congruent to ∠PSR, because they are not angles at the endpoints of the cross diagonal.

Answer: correct options are A, B and E.

The sum of two and the quotient of a number xxx and five. <br><br> write an equation
Alina [70]

we have to write an equation

The sum of two and the quotient of a number x and five

Firstly, we will find the quotient of a number x and five

For finding quotient , we always divide

For example: if we have to find quotient of a number 10 and 2

so,

quotient is

=\frac{10}{2}

Similarly , we have to find

the quotient of a number x and five

so, the quotient is

=\frac{x}{5}

now, we need to add 2 with quotient

so, we will get equation as

=2+\frac{x}{5}................Answer

The function f(x) = –x2 – 4x + 5 is shown on the graph. On a coordinate plane, a parabola opens down. It goes through (negative
vagabundo [1.1K]

Considering the vertex of the parabola, the correct statement is given by:

The range of the function is all real numbers less than or equal to 9.

<h3>What is the vertex of a quadratic equation?</h3>

A quadratic equation is modeled by:

y = ax^2 + bx + c

The vertex is given by:

(x_v, y_v)

In which:

  • x_v = -\frac{b}{2a}
  • y_v = -\frac{b^2 - 4ac}{4a}

Considering the coefficient a, we have that:

  • If a < 0, the vertex is a maximum point, which means that the range is all real numbers less than or equal to y_v.
  • If a > 0, the vertex is a minimum point, which means that the range is all real numbers greater than or equal to y_v.

In this problem, we have that:

  • a = -1 < 0, hence the vertex is a maximum point.
  • The vertex is (-2,9).

Hence the range is described by:

The range of the function is all real numbers less than or equal to 9.

Is my answer correct?
Yanka [14]

I would have used graph b. Because it shows the decrease more than graph a.
