PLEASE HELP ASAP!!! BRAINLEST!!

Answer:

They are not congruent because they are not facing the same way.

Step-by-step explanation:

SAS stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

That is which postulate proves congruency.

The following equation of a quadratic function is given in standard form. f(x) = x²- 2x + 2 Determine the vertex for each quadra

olganol [36]

Answer:

The vertex for each quadratic is $(x,y) = (1,1)$

Step-by-step explanation:

To determine the vertex for each quadratic,

The vertex of the $x$ coordinate can be determined using the formula,

$x-vertex = \frac{-b}{2a}$

The standard form of the quadratic function is

$f(x) = ax^{2} + bx + c$

Hence, for the given equation of the quadratic function,

$f(x) = x^{2} -2x +2$

$a = 1$

$b = -2$

and $c = 2$

Hence, $x-vertex$ becomes,

$x-vertex = \frac{-b}{2a}$

$x-vertex = \frac{--2}{2(1)}$

$x-vertex = \frac{2}{2}$

∴ $x - vertex = 1$

This is the vertex for the $x-coordinate$

To determine, the vertex for the $y-coordinate$

We will put the value of the vertex of the $x-coordinate$ in the equation and write

$y-vertex = x^{2} - 2x + 2$

Then,

$y-vertex = (1)^{2} -2(1) + 2$

$y-vertex = 1 - 2 +2\\y-vertex = 1$

This the vertex for the $y-coordinate$

Hence, $(x,y) = (1,1)$

Write the equation of a circle with a center at (2.5, –3.5) and a diameter of 12.

Paul [167]

Answer:

second option

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus

(x - 2.5)² + (y - (- 3.5))² = 6², that is

(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle
