When dropped, a super ball will bounce back to 80% of its peak height,continuing on in this way for each bounce.
Liono4ka [1.6K]

An expression for the height of the nth bounce is 0.80X^N = Height.

<h3><u>Equations</u></h3>

Since when dropped, a super ball will bounce back to 80% of its peak height, continuing on in this way for each bounce, to determine an expression for the height of the nth bounce the following calculation must be performed:

  • X = Initial value
  • 80% = 0.80
  • N = Number of times the ball bounces
  • 0.80X^N = Height

Therefore, an expression for the height of the nth bounce is 0.80X^N = Height.

Find the reciprocal
Sav [38]

Answer:

Depends on what number(s)/fraction(s) your working with.

Step-by-step explanation:

Find the reciprocal of a fraction by flipping it. The definition of "reciprocal" is simple. To find the reciprocal of any number, just calculate "1 ÷ (that number)." For a fraction, the reciprocal is just a different fraction, with the numbers "flipped" upside down (inverted).

PLEASE ANSWER I WILL MARK THE BRAINIEST ANSWER :)<br><br>factorise: X^2 + 10x + 16
Damm [24]

Answer:

(x+2)(x+8)

Step-by-step explanation:

1.)find factors of the third expression(16)that will add up to give the second expression(10)

16=2×8. 10=2+8

2.)substitute those factors inplace of 10

{x}^{2}  + 10x + 16

x {}^{2}  + 2x + 8x + 16

3.)factorise using grouping method

( {x}^{2}  + 2x) + (8x + 16)

x(x + 2) + 8(x + 2)

= (x + 2)(x + 8)
