The scale factor of dilation from AB to EF is 0.25
<h3>How to determine the scale factor of dilation?</h3>
The given parameters are:
- EFJL is dilation of ABIK
- AB has a length of 12
- EF has a length of 3
From the above parameters, side lengths AB and EF are corresponding sides
This means that:
The scale factor of dilation (k) is
k = AB/EF
So, we have
k = 3/12
Evaluate
k = 0.25
Hence, the scale factor of dilation from AB to EF is 0.25

Answer:
- t = 2.7 seconds
- t = 4.9 seconds
Step-by-step explanation:
<h3>Given </h3>
Function
<h3>To find</h3>
- Value of t when s(t) = 213
<h3>Solution</h3>
- 213 = -16t^2 + 122t
- 16t^2 - 122t + 213 = 0
- t = (122 ± √(-122)² -4*16*213)/2*16
- t = (61 ± √313)/16
- t = 2.7 seconds, t = 4.9 seconds
-43x + 16 < 79
Subtract 16 from both sides,
-43x < 63
Divide -43 from both sides,
x < -63/43
Hope this helps!
