Step-by-step explanation:

the scale factor is the ratio of corresponding sides, image to original, so

scale factor = $\frac{A'C'}{AC}$ = $\frac{9}{6}$ = $\frac{3}{2}$ = 1 $\frac{1}{2}$

Answer:

value of a in terms of b and c is: $\mathbf{a=bc}$

Option D is correct.

Step-by-step explanation:

We are given:

$a=b^2c^2d \:and\: d=\frac{1}{a}$

We need to find a in terms of b and c

We have: $a=b^2c^2d$

Put value of d $d=\frac{1}{a}$

$a=b^2c^2(\frac{1}{a})\\a^2=b^2c^2\\Taking \:squareroot\:on\:both\:sides\\\sqrt{a^2}=\sqrt{b^2c^2}\\a=bc$

So, value of a in terms of b and c is: $\mathbf{a=bc}$

Option D is correct.

Funcion. que a cada numero le asocia su mitad

expeople1 [14]

La función que a cada número le asocia su mitad es: f(x)= x/2

Explicación:

La mitad de una cantidad consiste en dividir el total en dos partes iguales, por lo tanto, la función debe representar una división entre el total y 2. Sea x el total, la función sería:

f(x)= x/2

Ejemplos:

La mitad de 20: f(20)= 20/2 = 10

La mitad de 8: f(8)= 8/2 = 4

La mitad de 100: f(100)= 100/2 = 50

La mitad de 2354: f(2354)= 2354/2 =1177

I dont understand what does this want me to do？

1. Construct a circle of arbitrary radius (r₁) with center at point P (blue circle)
2. Mark the points of intersection of the circle with the line AB (points E and D)
3. Construct two circles of identical radii (r₂) with centers at points E and D (green and red circles). Notice: r₂ > r₁
4. Draw a segment through the intersection points of the green and red circles.
