Answer:
1 2 real
2. No real
3. 2 Real
4. One real Multiplicity 2.
Step-by-step explanation:
Find the value of the discriminant D (b^2 - 4ac) :-
1 . D = (1)^1 -4 * -3 * 12 = 1 + 144 = 145
D is positive so there re 2 real solutions.
2. D = (-6)^2 - 4*2*5 = 36 - 40 = -4
D is negative so there are NO real solutions.
3. D = (7)^2 - 4 * 1 * -11 = 49 + 44 = 93
2 real
solutions
4. D = (-8)^2 - 4* -1 * -16 = 64 - 64
1 solution. Multiplicity 2.
Let x be an integer. And the consecutive integer = x+1.

Answer:
$9.60
Step-by-step explanation:
The question above is a simple interest question.
The formula for the amount of money after a given period of time using simple interest is given as:
A = P(1 + rt)
Where
P = Initial Amount saved or invested = $8
R = Interest rate = 5%
t = Time in years = 4
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Solving our equation:
A = 8(1 + (0.05 × 4)) = 9.6
A = $9.60
The amount of money that will be in a bank account after 4 years is $9.60
