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.

The total price including 7 percent tax on a $9.79 purchase is $10.67
A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
Given that, there is a 7 percent tax on a $9.79 purchase
Therefore, total price =
7% of 9.79 + 9.79
= 0.8811 + 9.79
= 10.67
Hence, the total price including 7 percent tax on a $9.79 purchase is $10.67
