A scientist is growing bacteria. The number of bacterial cells triples every week.

There are currently 20 cells.

Which expression shows how to find the number of cells in 4 weeks?

o f(4) = 3 20^4
o f (4) = 4 - 20^3
o f(4) = 20 - 3^4
o f (4) = 20 - 4^3​

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
