Answer: −420x+1073
Step-by-step explanation:
Let's simplify step-by-step.
955−105x(4)+118=955+−420x+118
Combine Like Terms:
=955+−420x+118=(−420x)+(955+118)=−420x+1073
Answer: =−420x+1073
Answer:
We have the function:
r = -3 + 4*cos(θ)
And we want to find the value of θ where we have the maximum value of r.
For this, we can see that the cosine function has a positive coeficient, so when the cosine function has a maximum, also does the value of r.
We know that the meaximum value of the cosine is 1, and it happens when:
θ = 2n*pi, for any integer value of n.
Then the answer is θ = 2n*pi, in this point we have:
r = -3 + 4*cos (2n*pi) = -3 + 4 = 1
The maximum value of r is 7
(while you may have a biger, in magnitude, value for r if you select the negative solutions for the cosine, you need to remember that the radius must be always a positive number)
I think the answer would be the 0.039.

d - distance
v - speed
t - time
Car A:

Car B:
15 mph faster than car A

Both cars traveled equal distances:

Car B traveled at the speed of 60 mph.
