Answer:
It is c im pretty surebecause it saysevery mile(x)is 2 so 2x
Step-by-step explanation:
I think you have to first separate the integral:1/(1+v^2) + v/(1+v^2),
so the integral of the first term is ArcTan (v) and for the integral of the second term i recommend you to do a change of variable:
y= 1+v^2
so
dy= 2v
and
v= dy/2and then you substitute:v/(1+v^2) = (1/2)(dy/y)
and the integral is
(1/2) (In y)finally you plug in the initial variables:
(1/2)(In [1+v^2])
so the total integral is:
ArcTan (y) + (1/2)(In [1+v^2])
Since 5 miles is equaled to 4 inches multiply the 8 miles by 4/5 to get 6 2/5
Answer:
a+8
Step-by-step explanation:
"sum" tells you to add the two numbers together.
You would distibute first distribute
6x-10=8
add 10 on both sides
6x=18
Then you divide 6 on both sides to get x by itself so
x=3
