Graph the image of this figure after a dilation with a scale factor of 1/3 centered at the origin.Use the polygon tool to graph the dilated figure.

Answers

Answer 1

Answer:

Answer:

see attached diagram

Step-by-step explanation:

A dilation with a scale factor of $(1)/(3)$ centered at the origin has a rule:

$(x,y)\mapsto\left((x)/(3),(y)/(3)\right).$

Then the image of the triangle ABC is triangle DEF(see attached diagram) with coordinates

$D\left((-3)/(3),(3)/(3)\right)\Rightarrow D(-1,1);$
$E\left((3)/(3),(9)/(3)\right)\Rightarrow E(1,3);$
$F\left((6)/(3),(6)/(3)\right)\Rightarrow F(2,2).$

The distance traveled, in miles, as a function of time, in hours, is defined by D(t). D(t) = Which times and distances are represented by the function? Check all that apply. The starting distance, at 0 hours, is 300 miles.
By 2 hours, the distance traveled is 725 miles.
At 2.5 hours, the distance traveled is 875 miles.
At 3 hours, the distance is constant, at 880 miles.
The total distance traveled in 6 hours is 1,062.5 miles.

Answers

*The complete question is attached in image form with this answer*

The correct options are:
(b) By 2 hours, the distance traveled is 725 miles.
(d) At 3 hours, the distance is constant, at 880 miles.
(e) The total distance traveled in 6 hours is 1,062.5 miles.

Explanation:
At t = 2 hours, the answer would be:

D(2) = 300(2) + 125 = 725 miles (at t lies in the range of 0 and 2.5) <-- (Option b).

At t = 3 hours, the answer would be:
D(3) = 880 (since t is in the range of 2.5 and 3.5) <-- Option (d)

At t = 6 hours the answer would become:
D(6) = 75(6) + 612.5 = 1,062.5 miles (since t is in the range of 3.5 and 6) <-- Option (e).

At t=0, D(0) = 300(0) + 125 = 125 ≠ 300 (since t lies in 0 and 2.5).
At t=2.5, D(2.5) = 880 ≠ 875 (since t lies in 2.5 and 3.5)
