Answer:
No
Step-by-step explanation:
7460400-7450400=10 000, that is ten thousand
To translate 4 units to the right, you replace
with
So we get
The common difference is d = 4 because we add 4 to each term to get the next one.
The starting term is a1 = 3
The nth term of this arithmetic sequence is
an = a1 + d(n-1)
an = 3 + 4(n-1)
an = 3 + 4n-4
an = 4n - 1
Plug in n = 25 to find the 25th term
an = 4n - 1
a25 = 4*25 - 1
a25 = 100 - 1
a25 = 99
So we're summing the series : 3+7+11+15+...+99
We could write out all the terms and add them all up. That's a lot more work than needed though. Luckily we have a handy formula to make things a lot better
The sum of the first n terms is Sn. The formula for Sn is
Sn = n*(a1+an)/2
Plug in n = 25 to get
Sn = n*(a1+an)/2
S25 = 25*(a1+a25)/2
Then plug in a1 = 3 and a25 = 99. Then compute to simplify
S25 = 25*(a1+a25)/2
S25 = 25*(3+99)/2
S25 = 25*(102)/2
S25 = 2550/2
S25 = 1275
The final answer is 1275
Answer:
0, $12.40, $24.79, $37.19, $49.58
0 ≤ f(g) ≤ 49.58
Step-by-step explanation:
The cost of fill up gas, f(g) as a function of number of gallons of gas needed (g) is given by f(g) = 2.479g ........(1)
So, f(0) = $0
f(5) = 2.479 × 5 = $12.40
f(10) = 2.479 × 10 = $24.79
f(15) = 2.479 × 15 = $37.19
and f(20) = 2.479 × 20 = $49.58
And the practical range of this function is 0 ≤ f(g) ≤ 49.58
Therefore, option D is correct. (Answer)
