Answer:
I'll give it straight: the following are rational numbers.
- Whole numbers
- Terminating decimals
- Repeating decimals
- Improper fractions (and all other fractions)
- (Integers, too)
- If square root is whole number, square root of a square is perfect, and therefore, rational
- Since a rational number is any number that can be written as a fraction, if a mixed number, such as 1 1/2, can be written as a fraction, then it is rational (1 1/2 can be written as 3/2, therefore it is rational)
Step-by-step explanation:
Answer:
It would be (-1,-3)
Step-by-step explanation:
All you have to do is divide your point by 4, since it's a fractions. If it's not, multiply.
-4 / 4 = -1
-12 / 4 = -3
Answer:
0.200
Step-by-step explanation:
∑ₓ₌₁⁴⁰ (1 + i)⁻ˣ = 5
∑ₓ₌₁⁴⁰ ((1 + i)⁻¹)ˣ = 5
This is a geometric series. The sum of the first n terms of a geometric series is:
S = a₁ (1 − rⁿ) / (1 − r)
where a₁ is the first term and r is the common ratio.
Here, a₁ = (1 + i)⁻¹, r = (1 + i)⁻¹, and n = 40. For simplicity, let's write both a₁ and r in terms of r. So a₁ = r and r = r.
5 = r (1 − r⁴⁰) / (1 − r)
5 (1 − r) = r (1 − r⁴⁰)
5 − 5r = r − r⁴¹
r⁴¹ − 6r + 5 = 0
Solving with a calculator, r ≈ 0.8334.
Therefore:
(1 + i)⁻¹ = 0.8334
1 + i = 1.200
i = 0.200
Answer:
Slope intercept form is y=2x+b
