That would be 644.8 / 31 = 20.8 feet / second
It’s not exactly equal to one, but in many cases in math they ask for a rounded answer.
Answer:
Equation 1
In the story it said Eli's mom doubled the money he left, that is what the two represents. 10 is the original amount he had. -k is the money he lost.
Equation 2
20 is the the result of the original 10 being multiplied. -2k, now the 2 is still the amount that the mom doubled his amount by, and the k is how much money Eli lost.
Hope this helps!!
Answer:
A If this is maths!!!
Step-by-step explanation:
If we rely solely on mathematics then the answer must be A. The other options seem to be from economy so it has nothing with mathematics. Please make sure that this is math task then answer.
An arithmetic sequence starts with one number and you add the common difference to the previous term to get the current term
So...
f(x)=mx+b
m=common difference
b=starting point
f(11)=125=11m+b
-
f(1)=5=1m+b
--------
120=10m
Divide both sides by 10
12=m
Your common difference is 12.
