<h3>
Answer: 36.4 units (choice A)</h3>
===========================================================
Explanation:
Let's use the distance formula to find the distance from D to E
Note: uppercase D refers to the point, while lowercase d is the distance from D to E.
The length of segment DE is roughly 10.198 units long.
----------------
Repeat for the distance from E to F.
Segment EF is roughly 11.1803 units long.
----------------
Repeat for the distance from F to D.
Unlike the others, this result is exact.
----------------
Add up the three segment lengths to get the perimeter
DE + EF + FD
10.198 + 11.1803 + 15
36.3783
The perimeter is approximately 36.3783 units which rounds to <u>36.4</u>
The answer has been confirmed with GeoGebra.
The answer is A
A function is a relation that associates all the elements in x with just ONE element in y. This means a number in x can only have one number in y, if it has more than one the relation is not a function.
A vertical line can't be a function because it associates one element in x with many elements in y
Answer:
d
Step-by-step explanation:
Answer:
The value of x is x
Step-by-step explanation:
Y=2x using the formula y=mx+b, m =rise over run which is 2/1, and b is zero since the y intercept is zero
