Answer:
9 M
Step-by-step explanation:
a^2+b^2=c^2
12^2+b^2=15^2
144+b^2=225
-144 -144
b^2=81
b=sqrt of 81
b=9
f(1) = 5; f(n) = 5 ⋅ d(n − 1), n > 0
f(1) = 5; f(n) = 5 ⋅ d(n + 1), n > 0
f(1) = 5; f(n) = 5 + d(n − 1), n > 0
f(1) = 5; f(n) = 5 + d(n + 1), n > 0
Answer:
f(1) = 5; f(n) = 5 + d(n − 1), n > 0
Step-by-step explanation:
Given
f(1) = 5
f(2) = 10
Required
Determine f(n)
From the formulas in the option, we understand that the sequence is Arithmetic.
And will be determined using
f(n) = a + (n - 1)d
Where a = f(1) = 5
Substitute 5 for a,
f(n) = 5 + (n - 1)d
Or
f(n) = 5 + d(n - 1)
To test,
Take n = 2
d = f(2) - f(1) = 10 - 5 = 5
So, we have
f(n) = a + (n - 1)d
f(n) = 5 + (2 - 1) * 5
f(n) = 5 + 1 * 5
f(n) = 5 + 5
f(n) = 10
Hence,
Option B answers the question.
Answer:
The person who answered above meant to say that it was C not B.
Step-by-step explanation:
His answer was (1) = 5; f(n) = 5 + d(n − 1), n > 0 and this would have been c not b. B would have been f(1) = 5; f(n) = 5 ⋅ d(n + 1), n > 0 which is incorrect.
Plz dont report me i'm just trying to correct the answer above.
And i'm not doing this for points either. Just trying to help people fix their mistakes so that others don't mess up, that is all.
Answer:
d
Step-by-step explanation:
the circumference of the moon is 10,921 km
The answer is 2 1/2. Because you need to cross cancel then you take the "freeway", and you get 5/2 and simplified is 2 1/2.And since half equals .5 it would be 2.5 just in case you also needed decimal.
