The formula is
A=p (1+r)^t
A future value 6678
P present value 5300
R interest rate 0.065
T time?
6678=5300 (1+0.065)^t
6678/5300=(1+0.065)^t
Take the log for both sides
Log (6678/5300)=t×log (1+0.065)
Divide both sides by log (1+0.065)
T=(log(6,678÷5,300)÷log(1+0.065))
T=3.7 years
Hope it helps!

Answer: Option 'a' is correct.
Step-by-step explanation:
As we know about the discriminant value i.e.
if we have given a quadratic equation :
then,
discriminant value will be
There are 3 properties regarding discriminant value as follows:
So, here we need a zero real number solutions i.e. there does not exists any real number.
So,
Hence, Option'a' is correct.
(a) The third side could be 6 cm long because the rule for this triangle is that the third side must be greater than 1 and less than 7. (4 - 3 = 1; 4 + 3 = 7) Then you can draw the triangle with Side 1 = 3 cm; Side 2 = 4 cm; Side 3 = 6 cm.
(b) The third side could not be 1 cm long because the rule for this triangle is that the third side must be greater than 1 and less than 7. (4 - 3 = 1; 4 + 3 = 7) This means that you cannot draw the triangle.
