Answer:

32 × 10^(10k)

Step-by-step explanation:

y = 16 x 10^8k

y^5/4 = ⁴√y^5

= ⁴√16^5 x 10^40k

= ⁴√2^20 x 10^40k

= 2^5 × 10^10k

= 32 x 10^(10k)

Answer: The right option that represents possible inputs and outputs of the function is the ordered pair

{(-2, -18), (2, 14), (0, -2)}

Step-by-step explanation:

By crosschecking;

Y=8x-2

When x=-2 , y= 8(-2) -2 , y= -16-2, y=-18 . (-2,-18)

When x=2 , y= 8(2) -2 , y= 16-2, y= 14

(2,14)

When x=0 , y= 8(0) -2 ,y= 0-2, y= -2

(0,-2)

Each side of a square is (7 + 3x) units. Which is the perimeter of the square?

galben [10]

If one side is 7 + 3x units then 4 sides of the square is 4 (7 + 3x).

4 (7 + 3x)
28 + 12x

Perimeter = 28 + 12x

What is the recursive formula for this arithmetic sequence 6, -24, 96, -384

Artemon [7]

Answer:

Option A. $a_{1} =6$ $a_{n}= a_{n-1}(-4)$

Step-by-step explanation:

The given sequence in the question is 6,-24,96,-384.......n

and we have to give the recursive formula for this arithmetic sequence.

We can re write the sequence to make it more simpler

6,6(-4),(-24)(-4),(96)(-4).......n terms

Now we can say $a_{1} = 6$

and $a_{n}= a_{n-1}(-4)$

Therefore the recursive formula of the sequence is $a_{1} = 6$

$a_{n}= a_{n-1}(-4)$

3/5 of a number is 162. Work out the number. How do I do this AQA question?

stiks02 [169]

Answer:

The number is 270

Step-by-step explanation:

Let the number be 'x'

3/5 of x = 162

$\frac{3}{5}*x = 162\\\\x=162*\frac{5}{3}\\\\x=54 * 5\\\\x = 270$
