A population of 800 cheetahs decreases by 6% per year. How many cheetahs will there be in the population after 8
years?

488

Step-by-step explanation:

Each year, 94% of the amount of cheetahs in previous year is left. Let's say we start with x. If x decreases by 10% a year, how much of x is left after 3 years? We would do, x * (0.9*0.9*0.9), which is 0.729x.

0.94 * 0.94 * 0.94 * 0.94 * 0.94 * 0.94 * 0.94 * 0.94 = 0.6095689385410813

800 * 0.6095689385410813 = 487.655151

We must round 487.655151 to 488.

Hope this helps :)

Have a nice day!

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
