TiliK225 [7]

Answer:

The number of different possible values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.

Step-by-step explanation:

Given : For an integer n, the inequality  \[x^2 + nx + 15 < 0\]  has no real solutions in x.

To find : The number of different possible values of n ?

Solution :

The given inequality is   \[x^2 + nx + 15 < 0\] have no solution then the discriminant must be less than zero.

i.e. b^2-4ac

Here, a=1, b=n and c=15

{n}^{2}  - 4 \times 1 \times 15  \: <  \: 0

{n}^{2}  - 60  \: <  \: 0  

n^2

n

n

i.e. - 7.75 \:  <  \: n \:  <  \: 7.75

The integer values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.

never [62]
For one year:
0.08(1800) + 1800
But because it is 5 years:
5(0.08(1800)) + 1800
0.4(1800) + 1800
We can make it simpler:
1.4(1800)
Multiply:
2520
