i really wish i could help but i have no idea );
Step-by-step explanation:
Multiplying both of them equals <span>−101</span>+<span>37<span>i</span></span>
PART 1.
Going westward:
Distance: 2400 miles
Rate (this is speed): (450-wind_speed) mph
Time: distance / speed = 2400 / (450-wind speed)
Going eastward:
Distance: 2400 miles
Rate (this is speed): (450+wind_speed) mph
Time: distance / speed = 2400 / (450+wind speed)
PART 2
Formula for speed:
speed = distance / time
Now we solve this for time:
time = distance / speed
11h = 2400 / (450+-wind_speed)
+- sign is put because in one case wind increases speed of plane and in other case it decreases speed.
PART 3
To solve for wind_speed we start by rearranging formula so that we have wind_speed on left side:
(450+-wind_speed) = 2400 / 11
(450+-wind_speed) = 218mph
To fly this distance in 11h speed of plane must be 218mph.
The only way to get this solution is if we substract wind speed:
450-wind_speed = 218
wind_speed = 450-218 = 232mph
<span>Lines are parallel if they are always the same distance apart (called "equidistant"), and will never meet. Therefore, from the figure, we can say that the lines are not parallel as these lines meet or intersects. Hope this answers the question. Have a nice day.</span>
Answer:
y = ⅔(x²)
Step-by-step explanation:
After vertical stretch of f(x), it becomes a×f(x) where a is the factor
Therefore,
New parabola: y = ⅔(x²)
