So we know that the bacteria grows 3x as much every ten minutes. From this we know that it'll be 3 mm in 20 minute. Continuing the pattern, we can figure out that in 40 minutes the bacteria will be 81 mm.
The pattern: 10min - 3 20min - 9 30min - 27 40min - 81
Answer:
<em>y = - 2x + 5 </em>
Step-by-step explanation:
m , ( , )
y - = m( x - )
~~~~~~~~~~~
m = - 2 and ( 4 , - 3 )
y - ( - 3 ) = - 2( x - 4 )
y + 3 = - 2x + 8
<em>y = - 2x + 5</em>
Factors of 75 and 100
75=1,3,5,15,25
100=1,2,4,5,10,20,25
25 is your greatest common factor
The general equation of a hyperbola with a horizontal transverse axis is defined as:
x²/a² - y²/b² = 1
Solving for b², we use the formula: a² + b² = c²
b² = 12² - 9² = 63
Equation of our hyperbola will be:
x²/81 - y²/63 = 1
