Answer:
I will be using differentiation method
Step-by-step explanation:
x^2+5x =-8
2×x ×x^2-1 +5x = -8
2x +5x = -8
7x = -8
divide both sides by the co-efficient of x
7x÷7=-8÷7
x =-1.5
since its the zeros it should be x -/+ something
(x-1)(x+1)(x+4)
multiply for standard form
((x^2)-1)(x+4)
x^3-x
+ x^2 -4
x^2 + x^2 -x -4
Answer: After 13 (12) hours, there would be 6,500 bacteria across the culture.
Step-by-step explanation:
The bacteria grew by 500 each 4 hours, so to know how much there would be 13 hours later:
Simple, add 500 bacteria to every 4 hours until you reach 13 hours. 4 = 5.5k, 8 = 6k, 12 = 6.5k. Now, 12 is closer to 13 than anything we would've gotten if we kept going.
And there's your answer.
If you could post the picture I can help
-2 + 6 < 4 equals 4 < 4.
First, simplify -2 + 6 to get 4. / Your problem should look like: 4 < 4.
If you are looking for the solution to this problem, there is none since 4 < 4 is false.
