Answer:
The largest even integer is 0
Step-by-step explanation:
Given as :
The sum of four consecutive even number = - 12
Let The first even number = 2 x
The second even number = (2 x + 2)
The third even number = (2 x + 4)
The fourth even number = (2 x + 6)
<u>According to question</u>
sum of four consecutive even number = - 12
Or, 2 x + (2 x + 2) + (2 x + 4) + (2 x + 6) = - 12
Or, (2 x + 2 x + 2 x + 2 x) + (2 + 4 + 6) = - 12
Or, 8 x + 12 = - 12
Or, 8 x = - 12 - 12
Or, 8 x = - 24
∴ x =
i.e x = - 3
now, putting the value of x
The first even number = 2 × - 3 = - 6
The second even number = (2 × - 3 + 2) = - 6 + 2 = - 4
The third even number = (2 × - 3 + 4) = - 6 + 4 = - 2
The fourth even number = (2 × - 3 + 6) = - 6 + 6 = 0
So, The largest even integer = 0
Hence, The largest even integer is 0 Answer
The equation for the situation is
It will take around 9 years for her to have around 5 sheep
Step-by-step explanation:
The exponential decay growth/decay equation is , where
- a is the initial value
- b is the growth/decay factor
- If b > 1, then it is a growth factor
- If 0 < b < 1, then it is a decay factor
Erica is a sheep farmer. She is having a problem with wolves attacking the flock. She starts with an initial 200 sheep and notices that the population is two-thirds of the previous year
∵ The population is decreased
∴ The equation is decay
∵ The population is two-thirds of the previous year
∴ The decay factor is
∵ She starts with an initial 200 sheep
∴ the initial value is 200
∵ The decay equation is , where y represent the
population in x years
∵ a = 200
∵ b =
∴
The equation for the situation is
∵ The population after x years is around 5 sheep
- Substitute y by 5 to find x
∵
- Divide both sides by 200
∴
- Insert ㏒ for both sides
∴
∴
- Divide both sides by
∴ 9.098 = x
∴ x is around 9 years
It will take around 9 years for her to have around 5 sheep
