If xy=0 we assume x and y equal 0
so
the zeros are wehre f(x)=0
0=5(2x-5)(5x+4)
set each to zero
5 is not equal 0 so we don't do that
0=2x-5
5=2x
5/2=x
0=5x+4
-4=5x
-4/5=x
zeroes at x=5/2 and -4/5
        
                    
             
        
        
        
Answer:
55
Step-by-step explanation:
In a triangle all the angles = 180 degrees
That means: x + y + 90 = 180
x + y = 180 - 90 = 90
35 + y = 90
y = 90 - 35 
y = 55 degrees

Answer: There are 2.25×10³⁴ bacteria at the end of 24 hours.
Step-by-step explanation:
Since we have given that 
Number of bacteria initially = 1
It triples in number every 20 minutes.
So, 
So, our equation becomes

We need to find the number of bacteria that it will contain at the end of 24 hours.
So, it becomes,

Hence, there are 2.25×10³⁴ bacteria at the end of 24 hours.
