Step-by-step answer:
Given:
Geometric sequence with
second term, T2 = 6
third term, T3 = 12
Wants to have the explicit and recursive rules.
Solution:
common ratio, r = 12/6 = 2
Therefore the first term, T1
= second term /r
= 6/2
=3
Thus the absolute rule is
Tn = T1 *r^(n-1) where T1 = 3, r=2. Check: T3 = T1*2^(3-1) = 3*2^2=12 ...good
The recursive rule (depending on the previous term)
Tn = Tn-1*r = 2*Tn-1
(f + g)(x) is x² + 4x - 4
<u>Step-by-step explanation:</u>
Step 1:
Given f(x) = 4x + 1, g(x) = x² - 5. Find (f+g)(x)
(f + g)(x) = f(x) + g(x) = 4x + 1 + x² - 5 = x² + 4x - 4
Answer:
5280 miles
Step-by-step explanation:
So, you are one third of the way to the mid point.
One-third can be represented as a fraction - .
The mid point will be half the race, so .
If you are a third of the way to the halfway point, you are done with the race.
If 880 miles is of the race, then the total amount of the race will be <em>6 times 880 (as </em>).
So the race in total is 5280 miles long.
Hope this helped!
Answer:
d=-6
Step-by-step explanation:
25% of 584 is 146. If you meant to say "25% off of the dealer's cost", the answer would be $438, since you're finding what 25% of the original price is (146) and subtracting it from the original price. The equation would be 584 - 146 = 438. I hope this helped <3
