Answer:
Step-by-step explanation:
The first step to solve this question is to analyze the given sequence.
We can notice that the difference between 8.5 and 7.15 is
And again the difference between the second and the third term is :
One way to describe all the numbers in the sequence is by using a formula.
We can write :
Given the sequence 
with 
∈ I
For example :
which verifies our original sequence.
We can obtain any term we want of the sequence.
Some of the terms that complete the sequence are :
Answer:
Step-by-step explanation:
Domain consists of all the input values shown on the x-axis. Range is the set of possible output values, which are shown on the y-axis.
DE = AB, EF = BC and AC = DF, hence triangle ABC is congruent to triangle DEF.
<h3>
Congruent shape</h3>
Two shapes are said to be congruent if they have the same shape, all their corresponding angles and sides are congruent to one another.
Given that DE = AB and BC = EF.
In right triangle DEF, using Pythagoras:
DF² = DE² + EF²
Also, In right triangle ABC, using Pythagoras:
AC² = AB² + BC²
But DE = AB and EF = BC, hence:
AC² = DE² + EF²
AC² = DF²
Taking square root of both sides, hence:
AC = DF
Since DE = AB, EF = BC and AC = DF, hence triangle ABC is congruent to triangle DEF.
