Mathematics
1 answer:
vitfil [10]3 years ago

Answer:

(4, 13/5)

Step-by-step explanation:

Aquí, estamos encontrando el punto que divide el segmento en 1/4

supongamos que tenemos la proporción 1: 4 como a: b

Matemáticamente, el punto que divide el segmento será;

Coordenada x = (bx1 + ax2) / (a ​​+ b)

donde (x1, x2) = (3,8)

Al conectar estos valores, tenemos; (4 (3) + 1 (8) / (1+ 4) = (12 + 8) / 5 = 20/5 = 4

Coordenada y = (by1 + ay2) / (a ​​+ b) donde (y1, y2) = (1,9)

Conectando estos valores que tenemos; (4 (1) + 1 (9)) / (1 + 4) = (4 + 9) / 5 = 13/5

Por lo tanto, las coordenadas del punto es (4,13 / 5)

The function h(x) is a transformation of the square root parent function,
kondaur [170]

Answer:

A. h(x)=\sqrt{x-3}

Step-by-step explanation:

<h3>Step 1: Definition</h3>

The parent function of \sqrt{x} is translated to the left when h is positive in the transformation \sqrt{x+h}.

If h is negative, the graph translates towards the left with the distance equal to the value of h.

<h3>Step 2: Implementation</h3>

Here the graph moved 3 units towards the right. This means that h is negative and has the value of 3.

So, plugging that into the parent function for translation, the function becomes:

h(x)=\sqrt{x-3}

The graph of the function f(x)=−4(x−3)2+9 will be a parabola opening in which direction?
sesenic [268]

Answer:

downwards

Step-by-step explanation:

the equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

• if a > 0 then parabola opens upwards

• if a < 0 then parabola opens downwards

for

f(x) = - 4(x - 3)² + 9 with a = - 4 < 0 , then

the parabola opens downwards
