Mathematics
1 answer:
Lunna [17]3 years ago
3 0

Answer:

2nd option

Step-by-step explanation:

trinomial is 2x² + 10x -4 = 0

a = 2

b = 10

c = -4

(-b±√b²-4ac) / 2a

= [-10±√100-4(2)(-4)] / 2

= (-10±2\sqrt{33}) / 4

= (-5+\sqrt{33})/2, = (-5-\sqrt{33})/2  (simplified)

Zelda has 8 rabbits with which to start an animal farm. If the rabbit population doubles each month, in how many months will the
Nana76 [90]

Answer:

9.5 months

Step-by-step explanation:

We would be using the expression

y = abⁿ

Where

a = starting number = 8 rabbits

b = rate of change = the number of rabbits doubles = 2

n = number of time intervals that has passed = unknown = number of months

y = rabbit population = 5800

y = abⁿ

5800 = 8 × 2ⁿ

Divide both sides by 8

5800 ÷ 8 = 2ⁿ

725 = 2ⁿ

n = 9.5 months.

Therefore, the number of months in which the rabbit population would reach 5,800 is 9.5 months
