Step-by-step explanation:
The nth term of a geometric progression can be determined by using the formula:
Tn=arn−1
where: a = first term and r = common ratio
Substitute the given values of first term and common ratio into the formula:
Tn=arn−1
T5=(40)(0.5)5−1
T5=(40)(0.5)4
T5=(40)(0.0625)
T5=2.5
Answer:
It's fine. It is a function. The language can be very convoluted. Put simply a domain value cannot have 2 different range values.
Step-by-step explanation:
The confusing part I think, is probably the fact that -1 and 1 both have an answer of 5.
That's fine. Parabolas do that and they are functions. Two different xs can have the same value. The thing that eliminates functions is when the x value (the domain) has two different y values (the range values). Then you don't have a function.
To try and make it clearer if 1 pointed at both 3 and 5 you would not have a function.
Product tells us we’re going to multiply.
6 x 6r = 36r
8s x 4 = 32s
We don’t have a number value to substitute in for r or s, so we just leave those variables as they are.

Answer:

Step-by-step explanation:

Answer: AB/y = BC/z = AC/x
Step-by-step explanation:
Side AB corresponds to side y, side BC corresponds to side z, and side AC corresponds to side x.
