Answer:

general, factored, and vertex form.

general: y=ax^2+b^2+c

Factored: y=(x+a)(x+b)

Vertex: y=a(x-h)^2+k

What is the order of magnitude

Angelina_Jolie [31]

Answer:

El orden de magnitud de un número es la potencia decimal del valor relativo de su cifra significativa. Por tanto, se dice por ejemplo que dos números difieren 2 órdenes de magnitud si uno es 100 veces más grande que el otro.

Let AB // ED , AB = 10 units, AC = 12 units, and DE = 5 units. What is the length of AD?

zheka24 [161]

Answer:

length of CD = 18 units.

Step-by-step explanation:

In ΔABC and ΔCED,

AB║DE and AD is a transversal line,

m∠ABC = m∠CED [Alternate interior angles]

m∠ACB = m∠DCE [Vertically opposite angles]

ΔABC ~ ΔCED [By AA property of similarity]

Therefore, by the property of similar triangles, corresponding sides will be proportional.

$\frac{AB}{DE}= \frac{AC}{DC}$

$\frac{10}{5}=\frac{12}{CD}$

CD = 6

Since, AD = AC + CD

AD = 12 + 6

= 18 units

Therefore, length of CD = 18 units.
