Answer:
x ≈ 14.7 
Step-by-step explanation:
use pythagorean therorem 
a^2 + b^2 = c^2
c is hypotenuse and we know the hypotenuse is 21
a^2 + b^2 = c^2
x^2 + 15^2 = 21^2
x^2 + 225 = 441
x^2 = 216
x = √216
x ≈ 14.7
 
        
             
        
        
        
Answer:
(0, 1)
Step-by-step explanation:
p(x) =2^x
- p(x) - is number of bacteria
- x - time, hour
Solution of p(x) = 1
Indicating initial number of 1 in the beginning
Coordinate of (0, 1) is the solution

If you're only dealing with integers, then the answer is:
[-8 , -3)
If you're dealing with real numbers, then the answer is:
[-8, -3)∪(-3, -2)
