Answer:
55.734 mph
Step-by-step explanation:
Let's call the wind speed x and the time of flight t.
Then, we can write the following equation, knowing that the distance is equal speed times time of flight:
910 = (350+x) * t
660 = (350-x) * t
If we isolate t in both equations and compare its value, we have that:
910 / (350+x) = 660 / (350-x)
(350+x)/(350-x) = 910/660
350 + x = 1.3788 * (350-x)
350 + x = 482.58 - 1.3788x
2.3788x = 132.58
x = 55.734 mph
The rate of change per year is 3 million per year.
Answer:
B, C, E
Step-by-step explanation:
you need to find lines whose slope is the negative reciprocal of the slope from the line you are solving for. in this case, all lines with the slope -1/2 are Perpendicular to a line with the slope of 2
Interest due at the end of 120 days
= 8500(120/365)(.09) = 251.51
so of his $4000 payment, $3748.49 will go towards reducing the debt.
so balance owing = 8500 - 3748.49
= 4751.51
interest for the remaining 80 days
= 4751.51(.09)(80/365) =93.73
total owing at the end = 4751.51+93.73
= $4845.23
(4,1) can be taken out.
The input and output values cannot be the same.
Hope this helps!
