Step-by-step explanation:
Rate of growth equals 420/100 = 4.2 times per hour
So after t=three hours,
size of culture = 100*(4.2)^t = 100*4.2^3=7408.8 bacteria,
round to nearest unit 7409 bacteria after three hours (after initial size of 100).
Answer:
1. x^2-9x+18
2. 2x^2-4x-16
3. 3x^2-19x-14
4. 6x^2 +14x + 8
Step-by-step explanation:
1. (x-3)(x-6)
x^2 - 6x - 3x +18 = x^2-9x+18
2. (2x+4)(x-4)
2x^2-8x+4x-16 = 2x^2-4x-16
3. (x-7)(3x+2)
3x^2+2x-21x-14 = 3x^2-19x-14
4. (3x+4)(2x+2)
6x^2+6x+8x+8 = 6x^2 +14x + 8
