Question 4 (5 points)
AABC was dilated to form ADEF.
What scale factor was used in the dilation?
HELP ASAP

The scale factor was used in the dilation is 3

Step-by-step explanation:

Dilation is a kind of transformation that changes the size of figures

Image of a figure by dilation and the figure are similar

If a triangle dilated by a scale factor k then its image is similar to it, and the constant ratio between their corresponding sides is equal to k

∵ Δ ABC is dilated to form Δ DEF

∴ Δs ABC and DEF are similar

- That mean their corresponding sides have constant ratio

   equal the scale factor of dilation

∴

Size of Δ DEF is greater than size of Δ ABC, that means k > 1

∵ AC = 2 units

∵ DF = 6 units

∵

∴

∴ 3 = k

∵ The scale factor of dilation is equal to the constant ratio k

∵ k = 3

∴ The scale factor was used in the dilation is 3

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
