Option B:
The 12th term is 354294.
Solution:
Given data:
and
To find
The given sequence is a geometric sequence.
The general term of the geometric sequence is .
If we have 2 terms of a geometric sequence and (n > K),
then we can write the general term as .
Here we have and .
So, n = 7 and k = 4 ( 7 > 4)
This can be written as
Taking cube root on both sides of the equation, we get
r = 3
Hence the 12th term of the geometric sequence is 354294.
x=-7
We can write them both like functions like this
A= 5x -4
B= 3x +8
Where
x=input
A=Output A
B=Output B
We want the output of A 3 times the output of B this can be written like this:
A= 3b
we replace with the functions
5x-4 = 3(3x+8)
solve for x and you get -7
Answer:
yes it very is..................
Step-by-step explanation:
........
For this case we have the following variables:
x: number of hours that it takes Mr. David to complete a job working alone.
y: number of hours it takes Mr. Ludwing to complete a job working alone.
k: number of hours it takes for both of them to do a job working together.
We now write the equation that models the problem.
To do this, we must add the work rate per hour of each and equal to the rate of work per hour of both.
We have then:
Answer:
The algebraic expression that models the problem is:
15 mph = 15 miles traveled in a one hour time span.
15+3=18 miles, 60 minutes- 30 minutes = 30 minutes.
18 miles in the span of 30 minutes
