Short Answer: Current speed = 3 miles per hour. Given details for downstream distance of 4.48 miles at time 0.32 hours and upstream distance of the same 4.48 miles taking 0.56 hours. Using the equation d = r*t, we equate distances for both directions leading to a function in terms of the current speed. With each correction to solve ultimately yields the current speed as 3 mph.
Answer: B: n^2+6n+1
Step-by-step explanation:
A=n
B=2n+6
C=n^2-1
AB-C
n(2n+6)-n^2-1
2n^2+6n-n^2+1
n^2+6n+1
The slope equals $0.10 (since $1.00 per 10 tokens translates to $0.10 per token)
The y-intercept is $60 (the fixed yearly membership fee)
The linear equation is y = 0.10x + 60 (following y = mx + b)
The domain consists of all x values where x ≥ 0 (negative token quantities are impossible)
The range includes all y values with y ≥ 60 (plugging the domain values into the function)
The y-intercept of this function stands at $60
Four statements:
1) Start by dividing the x-axis into equal segments.
2) n = 212/5 = 42.4.
3) Each segment along the x-axis represents 42.4. This means you can plot the point -212 at x = -5
4) The y-axis can keep its magnitude and you can plot the coordinate of -4 at y = -4
Ella utilized 60% more than what was necessary, indicating she used (1 + 0.60) = 1.60 times the required amount. Man, I'm pleased to see you know some Spanish. Good luck, buddy!
