Answer:
Step-by-step explanation:
Depending on what type of fraction you're trying to simplify there are different ways.
One subtraction example would be:
6-3/7-4 you minus the numerator and denominator to get 3/3 since we have 3 on both top and bottom our simplified answer would be 1
Let 'x' be the distance from THE far bank where 700 is the distance to the NEAR bank
boat one has travelled 700 (rate = 700/unit time) boat two has travelled x rate = x / unit time
boat one then travels x + 400 more and boat two travels 700 + (700+x -400) more when they meet
The time is the same rate x time = distance distance/rate = time equate the distances divided by the respective rates
(700 + x + 400)/700 = ( x + 700 + (700+x-400) )/x
1100x + x^2 = 1400x + 700000
x^2-300x -700000 = 0 quadratic formula yields x = 1000
One boat travels 700 the other 1000 whe they first meet.....width of river = 700+ 1000 = 1700 m
-20 because 40 is a positive and spent is negative
The maximum number of turning points in a cubic function is 2.
In this case,
The discriminant is
, which means the derivative has no real roots. This means there are no critical points and thus no turning points/relative extrema.
To get the difference between the two diameters, all you have to do is subtract the smaller diameter (Mercury) from the larger diameter (Saturn) as follows:
Difference between the two diameters =diameter of Saturn-diameter of Mercury
Difference between the two diameters = (1.2*10^5) - (4.9*10^3)
Difference between the two diameters = 115100 km
