Given:
Triangle DEF
To find:
The perimeter of triangle DEF.
Solution:
Coordinate of D = (-1, 1)
Coordinate of E = (2, 1)
Coordinate of F = (-1, 4)
Distance formula:

<u>Distance of DE:</u>
Here, 


d = 3 units
<u>Distance of EF:</u>
Here, 



d = 4.2 units
<u>Distance of FD:</u>
Here, 


d = 3 units
Perimeter of ΔDEF = DE + FE + FD
= 3 + 4.2 + 3
= 10.2 units
The perimeter of triangle DEF is 10.2 units.
<u><em>Hello, this should help you out!</em></u>
In this graph, the y values move up 3 units each. Therefore, the blue parabola underwent a translation of 3 units upward.
For further explanation, we see that (0,0) goes up to (0,3), meaning the graph shifted upwards 3 units. So, each y value is raised by positive 3 units!

Answer:
1.2
Step-by-step explanation:
So in the picture, there is the working out I did (sorry for the bad writing). When you work out the question, remember to match the decimal points (I've done this in the pic). The answer I got was 1.20 but that is the same as 1.2.
hope this helps :)
The money would be multiplied by a factor of 16 after 28 years
<h3>How to determine the factor?</h3>
The rate is given as:
Rate = Double every 7 years
There are 4 7 years in 28 years.
So, the factor would be:
Factor = Rate^4
This gives
Factor = 2^4
Evaluate
Factor = 16
Hence, the money would be multiplied by a factor of 16 after 28 years
