4x^5 – x^4
Step-by-step explanation:
i took it and was correct
Marie because if you put a 0 behind .4 that equals .40 and then you compare .25 and .40 therefore .25 is closer
The explicit formula of the arithmetic sequence:

d - common difference
We have the recursive formula of an arithmetic sequence:

Therefore we have:

Substitute:

<h3>Answer: aₙ = 7 - 3n</h3>
Speed is given by the formula:
speed=distance/ time
this implies that when we rewrite the above formula for distance we shall have:
distance=speed*time
from our question:
speed=60 mph
time=3 1/2 hours=3.5 hours
thus
distance=60x3.5
=210 miles
the answer is 210 miles
