Mohamed and Li Jing were asked to find an explicit formula for the sequence -5\,,-25\,,-125\,,-625,...−5,−25,−125,−625,...Minus,
ANTONII [103]
Answer:
the equation is given as 
Explanation:
As the sequence is given as −5,−25,−125,−625,...
From this the first term is given as
a1=-5
Now the relation between this term and the next term is to be observed.
d=a2-a1=-25-(-5)=-25+5=-20
d=a3-a2=-125-(-25)=-125+25=-100
Now it is observed that the difference is not same this indicates that the relation is not arithmetic.
next up is the geometric sequence so the value of ratio is given as
r=a2/a1=-25/-5=5
r=a3/a2=-125/-25=5
As the ratio is same this indicates, this is a geometric sequence.
Now for the geometric sequence, the value of the general term is given as
Here a1=-5 and r=5 so the equation is given as
Answer:
Number 2- Misreading the data is a very serious issue
Explanation:
Answer:
What these stars most have in common is that they are in hydrostatic equilibrium during the main sequence.
Explanation:
These stars are quite diverse and cover a wide spectrum of size and brightness since they are the most numerous group of stars in the entire universe.
A main sequence star:
- has not yet consumed all the hydrogen in its core
- can be yellow, white or blue but not yet a dwarf star
Hello There,
The answer is :
because it is covered in ice
because it has a deep ocean beeath
becasue there is a chance it hosts life
Hope this help have a great day :)
We can draw the conclusions that the rock is sedimentary rock due to it's feature that is formed by different rocks, and from the round pebbles we can deduce that the rock is a conglomerate
