Answer: The infinite geometric series converges to 38.4
====================================================
Explanation:
Divide each term by its previous term
term2/term1 = 9.6/19.2 = 0.5
term3/term2 = 4.8/9.6 = 0.5
The common ratio is r = 0.5
Since -1 < r < 1 is true, this means the infinite geometric series converges.
It converges to...
S = a/(1-r)
S = 19.2/(1-0.5)
S = 38.4
Answer:
7
Step-by-step explanation:
3x- 1/9y = 18
value of x when y is 27
3x- 1/9*27 = 18
3x- 3 = 18
3x = 18 + 3
3x = 21
x= 21/3
x = 7
Hope this helps you!
Answer:
8 = 3a + 4
4=3a
4/3=a
hope this helps
have a good day :)
Step-by-step explanation:
Answer:
Because we only work with positive bases, bx is always positive.
Step-by-step explanation:
The values of f(x), therefore, are either always positive or always negative, depending on the sign of a. Smaller values of b lead to faster rates of decay.
4 7/8 + 2 3/8 =
= 39/8 + 19/8
= (39 + 19)/8
= 58/8
= 7 2/8
= 7 1/4 miles
