Hmm, I got these for roots:
0.7937053103356799
0.026855090968934903 +i* 1.6611004538114105
0.026855090968934903 -i* 1.6611004538114105
-6.84741549227355
40% is equal to 0.4
10 / .4 = 25
40% of 25 is 10.
Hope this helps!
Answer:
0 or -5/768
Step-by-step explanation:
192x * 4 is 768x
Now you have 768x=-5
If you divide both sides by 768 you get -5/768
In decimal form that is -0.006510416
If you round the decimal to the nearest tenth you get 0
I hope this helps!
Please give brainliest if it did help
Step-by-step explanation:
We want to find two things-- the speed of the boat in still water and the speed of the current. Each of these things will be represented by a different variable:
B = speed of the boat in still water
C = speed of the current
Since we have two variables, we will need to find a system of two equations to solve.
How do we find the two equations we need?
Rate problems are based on the relationship Distance = (Rate)(Time).
Fill in the chart with your data (chart attached)
The resulting speed of the boat (traveling upstream) is B-C miles per hour. On the other hand, if the boat is traveling downstream, the current will be pushing the boat faster, and the boat's speed will increase by C miles per hour. The resulting speed of the boat (traveling downstream) is B+C miles per hour. Put this info in the second column in the chart. Now plug it into a formula! <u>Distance=(Rate)(Time) </u>Now solve using the systems of equations!
