A quadratic equation has either two different real roots, one real root, or two conjugate complex roots (this is the case when the discriminant is negative, i.e. when you have no real roots).
Two conjugate complex roots have the same real part and opposite imaginary parts. So, the solutions to Amina's equation will be in this form:
For some
Answer:
(c)
(ii)
Step-by-step explanation:
(a)The rate of growth of the population is proportional to the population, this is written as:
(b)
(c)
Suppose the net birthrate of the population is .1, and the initial population is 100.
k=0.1
P(0)=100
Substitution into P(t) gives:
C=100
Therefore:
(i)When t=10
(ii)When t=1000
Answer:
13/3 or 4 1/3
Step-by-step explanation:
First you convert your mixed numbers into improper fractions:
5/3 × 13/5
You can reduce these fractions by the greatest common factor of 5
1/3 × 13
Multiply
1/3 × 13 = 13/3 or 4 1/3
4,000 +000 +00 + 0 is stander form for four thousand
