Mia enlarged a plan for an outdoor stage. The original plan is shown below. She dilated the outdoor stage by a scale factor of 4
with the center of dilation at the origin. Which ordered pair will be the coordinates of one of the new vertices? A (2,1) B (8,16) C (32,4) D (32,16)

Answer:
D (32,16)
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please see the attached photo.
In the photo, the four vertices are:
(-5,4) by a scale factor of 4 (-20, 16)
(8, 4) by a scale factor of 4 (32, 16)
(-6, -2) by a scale factor of 4 (-24, -8)
(8, -2) by a scale factor of 4 (31, -8)
So only D is correct.
Hope it will find you well.

In the given diagram, line BG bisects ∠ABC and ∠DEF, m∠ABC= 112°, and ∠ABC≅∠DEF. So the measure of angles are :
1. m∠DEF= 112° because ∠ABC≅∠DEF
2. m∠ABG= 56° because a straight line BG is bisecting ∠ABC in two equal parts. So,
3. m∠CBG= 56° because ∠ABG and ∠CBG are equal.
4. m∠DEG= 56° because ∠ABG ≅ ∠DEG
Answer:
400%
Step-by-step explanation:
Let the sales be "100" in 1994
Since, it decreased 80%, the sales was:
80% = 80/100 = 0.8
0.8 * 100 = 80 (decreased by 80)
So, it was
Sales in 1995: 100 - 80 = 20
Sales in 1996 was same as in 1994, so that's 100
Thus,
Sales in 1994: 100
Sales in 1995: 20
Sales in 1996: 100
We need to find percentage increase form 1995 to 1996, that is what percentage increase is from 20 to 100?
We will use the formula:
Where
New is 100
Old is 20
SO, we have:
So, it increased by 400%
