Answer:
10th term is 10
Step-by-step explanation:
The nth term for finding the geometric progression is expressed as;
Tn = ar^n-1
a is the first term
r is the common ratio
n is the number of terms
a11 = ar^11-1
a11 = ar^10
Since a11 = -5 and r = -1/2
-5 = a(-1/2)^10
-5 = a(1/1024)
a= 1024 * -5
a = -5120
Nest is to get the 10th terms
a10 = ar^9
a10 = -5120 * (-1/2)^9
a10 = -5120 * -1/512
a10 = 10
Hence the 10th term of the sequence is 10
The rule for multiplying similar bases with exponents is:
(a^b)*(a^c)=a^(b+c)
In this case you have:
(x^9)(x^2)
x^(9+2)
x^11
Answer:
A A A B B B C C C
Step-by-step explanation:
We have the Greedy algorithm, the solution at any time is considered an optimal algorithm.
In our case the sequence is x x x y y y z z z
In addition to the Greedy algorithm, the first advertiser chooses their choice without considering the minimum methods.
Now we must consider the worst case of greedy algorithm so we must suppose that it starts from advertiser C, then B and followed by A.
Therefore the worst option would come being:
C C C B B B, in addition that A cannot bid for any query.
Which means that the sequence of the balanced algorithm will be A A A B B B C C C
Answer:
whatever is higher than 1.5 is higher than r
Step-by-step explanation:
-1.2 ≤ -0.8r
-1.2/0.8 ≤ -0.8r/0.8
-1.5 ≤ -r
-1.5/-1 ≤ -r/-1
1.5 ≥ r
1.5 is equal to or bigger than r
The answer is 18 inches.
Let r=radius and d=diameter
2r=d
2(9)=d
18=d
Hope this helps!
