answer:

okay so i did it and i got these answers

- y = 20

- 4^8

- x = 0

step-by-step explanation:

my work

- p^3 × p^5 = p^-12 × p^y then 3 + 5 = -12 + y so: 20 = y

64 × 4^5 = 4^3 × 4^5 = 4^(3+5) so: its 4 over 8

10^x = 1 = 10^0 so: its 0

hope this helped :) pls give me brainliest <3

Answer:

y = 20
4^8
x = 0

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

a^0 = 1 . . . . for a ≠ 0

And, it is convenient to know the cubes of small integers:

1³ = 1; 2³ = 8; 3³ = 27; 4³ = 64; 5³ = 125

6³ = 216; 7³ = 343; 8³ = 512; 9³ = 729; 10³ = 1000

1) p^3 × p^5 = p^-12 × p^y

Equating exponents:

3 + 5 = -12 + y

20 = y . . . . . . . . . . . add 12

2) 64 × 4^5 = 4^3 × 4^5 = 4^(3+5) = 4^8

3) 10^x = 1 = 10^0

x = 0

What is the recursive rule for the sequence 2, -1, 1/2 , -1/4

Helga [31]

Answer:

$a_n=\frac{-1}{2}a_{n-1}$

$a_1=2$

Step-by-step explanation:

The recursive rule is a term defined in terms of other terms in the sequence.

The is a geometric sequence because it has a common ratio.

The common ratio can be found by dividing a term by previous term.

For example, all of these are equal:

$\frac{-1}{2}$

$\frac{\frac{1}{2}}{-1}$

$\frac{\frac{-1}{4}}{\frac{1}{2}}$

They are all equal to $\frac{-1}{2}$ .

So we are saying:

$\frac{\text{term}}{\text{previous term}}}=\frac{-1}{2}$

More formally:

$\frac{a_n}{a_{n-1}}=\frac{-1}{2}$ .

Multiply both sides by $a_{n-1}$ :

$a_n=\frac{-1}{2}a_{n-1}$

When doing recursive form, you need to state a term of the sequence (or more depending on the recursive form you have).

So the first term is 2.

So the full thing for the answer is:

$a_n=\frac{-1}{2}a_{n-1}$

$a_1=2$
