Answer:
I think it is 123 for number 9 i can't see, the other problems
Step-by-step explanation:
Answer:
3(60/10)
Step-by-step explanation:
10 students require 3 cookies, which you already know. So, since you need to find for 60, you can divide 60 by 10 into 6. Then, 6x3 will equal 18. Or, you can say:
10=3
20=6
30=9
40=12
50=15
60=18
10x2=3x2 and so forth....
Answer:

You gave the explicit form.
Step-by-step explanation:
You gave the explicit form.
The recursive form is giving you a term in terms of previous terms of the sequence.
So the recursive form of a geometric sequence is
and they also give a term of the sequence; like first term is such and such number. All this says is to get a term in the sequence you just multiply previous term by the common ratio.
r is the common ratio and can found by choosing a term and dividing by the term that is right before it.
So here r=-3 since all of these say that it does:
-54/18
18/-6
-6/2
If these quotients didn't match, then it wouldn't be geometric.
Anyways the recursive form for this geometric sequence is

Answer:
There are no amount of anything that u included just the actual product
Step-by-step explanation:
Pythagorean theorem= a^2 + b^2= c^2
The sides are a & b and the hypotenuse is c.
a= 9ft
b= 12ft
c= ?
a^2 + b^2= c^2
(9)^2 + (12)^2= c^2
81 + 144= c^2
225= c^2
take the square root of 225 and c
15= c
ANSWER: c= 15 feet
Hope this helps! :)
