First, know which two sides are parallel. Then, go to the corners of the shorter side and draw a perpendicular line connecting to both sides
<h2>
Change of the distance between the observer and the airplane when X = 5 miles is 348.84 mph</h2>
Step-by-step explanation:
We have by Pythagoras theorem
Distance between the observer and the airplane² = Horizontal distance² + Altitude²
d² = h² + a²
Here we have
h = X = 5 miles
a = 7 miles
d² = 5² + 7² = 74
d =8.60 miles

Differentiating d² = h² + a² with respect to time

Change of the distance between the observer and the airplane when X = 5 miles is 348.84 mph
For the first question:
C.) $240
For the 4 year plan you take $332 a month and multiply by 12 to get the annual value of $3,984. Then multiply that by 4 to get $15,936.
For the 3 year plan take $436×12 to get $5,232, then multiply that by 3 years and you get $15,696.
Finally, to find the difference do $15,936-$15,696 and you get $240.
For the second question:
The new value is between 10 and 12.
Mean refers to the average between all the data paints, while the mean absolute deveiation is the average distance between the data point and the mean. So if the value was 11, for example, the mean, or average would increase from 10, while the MAD would only be 1, decreasing it.
Answer:
j=3+25, here's the equation
Step-by-step explanation:
J=28
Well, the angle looks like it is an obtuse angle, right? And we know that obtuse angles are greater than 90 degrees, so wouldn't the answer be A. 115 degree?
I think the answer is 115 degrees. Hope this helps!
