8th term is 0.30

Step-by-step explanation:

  • Step 1: nth term of a GP = a × r^n-1
  • Step 2: Find r.

⇒ r = a2/a1 = 216/648 = 1/3

  • Step 3: Calculate 8th term. a = 648, r = 1/3 and n = 8

⇒ 8th term =  648 × (1/3)^8-1 = 648 × (1/3)^7 = 648/2187 = 0.30

Answer:

<em>The translation corresponds to a translation of 13 units to the right</em>

Step-by-step explanation:

<u>Translation of a Graph</u>

If the graph of

y=f(x) is translated a units horizontally, then the equation of the translated graph is

y =f(x - a)

The value of a is considered positive for translations to the right.

The parent function is

y = x

and the given function is

y = x - 13

The translation corresponds to a translation of 13 units to the right

You buy 21 lbs of cucumbers which are 92% water. A few days later they’re 85% water. How much do they weigh then?
IrinaK [193]
To solve this, you must find the initial weight of the cucumber. To do this, you must divide the weight by the percentage of water and multiply it by 100.

(21/92)×100=22.83lbs.

Then, you multiply it by 85% and divide it by 100. Or simply multiply it by 0.85.

22.83×0.85=19.41lbs.
