A population of 805 cheetahs decreases by 10% per year. How many cheetahs will there be in the population after 6 years?
Phantasy [73]

Answer:

Step-by-step explanation:

y = a(b)^x

a would represent the initial value.

b would represent the change

x represents the number of years

y = 805(0.9)^6

y = 805(0.531441)

y = 427.8

y =  427 cheetahs

Can someone answer this please??

Volume of A = 1728

volume of B = 729  

<span> (1728 / 729) = (a / b)^3  (a = width of A, b = width of B)
  a / b = cube root (1728 / 729)  = 4/3   </span><span> b = 10 (given)
a / 10 = 4/3 </span><span>
  a = 40/3 = 13.33333</span>
 so width of A is 13.33m
