top left: speed = 2.7 miles per hour  = 2.7 MPH

top right: speed = 0 miles per hour  = 0 MPH

bottom left: speed = 4 miles per hour  = 4 mi/h

bottom right: speed = 2 miles per hour  = 2 mi/h

and so, the fastest is bottom left. And pay attention in class! i'm in highschool and Iearned this in 6th grade!

Step-by-step explanation:

key: speed= distance/time

distance= speedxtime

time=distance/speed

top left: 8/3= 2.66667 MPH= 2.7 MPH

top right: 0/8= 0 MPH= 0 MPH

bottom left: 8/2= 4 MPH= 4 MPH

bottom right: 8/4= 2 MPH= 2 MPH

Find the oth term of the geometric sequence 7, 14, 28, ...
yaroslaw [1]

Answer:

The nth term of the geometric sequence 7, 14, 28, ... is:

a_n=7\cdot \:2^{n-1}

Step-by-step explanation:

Given the geometric sequence

7, 14, 28, ...

We know that a geometric sequence has a constant ratio 'r' and is defined by

a_n=a_1\cdot r^{n-1}

where a₁ is the first term and r is the common ratio

Computing the ratios of all the adjacent terms

\frac{14}{7}=2,\:\quad \frac{28}{14}=2

The ratio of all the adjacent terms is the same and equal to

r=2

now substituting r = 2 and a₁ = 7 in the nth term

a_n=a_1\cdot r^{n-1}

a_n=7\cdot \:2^{n-1}

Therefore, the nth term of the geometric sequence 7, 14, 28, ... is:

a_n=7\cdot \:2^{n-1}

8s - 11s + 6

(8s - 11s) + 6

-3s + 6

-3s + 6 is your answer.
