Answer:
I will use x as the distance traveled in 7 hours
450/5.5 = x/7.7 - set up proportion
5.5x = 3465 - cross products
5.5x/5.5 = 3465/5.5 - divide each side by 5.5
x = 630 - answer
hope this helps.
Step-by-step explanation:
The quadratic equation is in factored form, which is f(x) = (x - a)(x - b), where a and b are the x-values for the x-intercepts.
The x-values for the x-intercepts are 4 and -2. We know that the y-value at any x-intercept must be 0 (otherwise it isn't an x-intercept).
Thus, either the points (4,0) or (-2,0) must be your answer (the question is only asking for one x-intercept).
Answer:
1) Distance in feet equals 1640.4 feet
2) Distance in miles equals 0.3107 miles.
Step-by-step explanation:
From the basic conversion factors we know that
1 meter = 3.2808 feet
Thus by proportion we conclude that
Similarly using the basic conversion factors we know that
1 mile = 1609.34 meters
thus we conclude that 1 meter =
miles
Hence by proportion 500 meters = 
miles
V=1/3Bh B=area of base h=height
2x + 3 + x = 39
3x + 3 = 39
3x = 36
x = 12
