3 is always on the numerator. It is not effected by a power. The answer has to be something that leaves the numerator alone. That means that B is not correct.
The answer is going to be something that makes the denominator 1 when n = 1. That's going to be the answer to the question, because the first term in the sequence is just 3. The denominator must be 1. (not zero).
D is not the answer, because 3/5^1 = 3/5, so D is wrong.
A is not going to get us anywhere either. 3/5^(1 + 1) = 3/5^2 = 3/25 which is not the first term.
The only choice we have left is C. It must be the answer. 3/5^(1 - 1) = 3/5^0 = 3/1 = 3. There's your answer. Note anything raised to the zero power = 1.
Answer:
2.4 miles
Step-by-step explanation:
3/10 miles per day * 8 days = 2.4 miles
Answer:
360 minutes
Step-by-step explanation:
Given that:
Driving down the hill (d) = 12 minutes
Driving up the hill (u) = 24 minutes
Days = Monday - Friday = 5days
For 2 weeks : 2 * 5 = 10
Total time taken to drive up and down daily (T) : (12 + 24) minutes = 36 minutes
For the two weeks :
10(T)
= 10(36)
= 360 minutes
Model:
Let number of days = n
Number of minutes :
n(u + d)
Answer:
The graph of f(x) has exactly two x-intercepts not true.
A straight line cannot intersect the x axis twice, so a graph should never have two x-intercepts.
Hope this helps!
Answer:
x^2 / 4pi
Step-by-step explanation:
The area of a circle is (pi x r)^2
The circumference of a circle is 2pi x r
The find the radius, you need to divide x by 2pi, so x / 2pi
Then just plug it in as the radius:
(pi x (x / 2pi))^2 = x^2 / 4pi
