Charlie is at a small airfield watching for the approach of a small plane with engine trouble. He sees the plane at an angle of elevation of 32. At the same time, the pilot radios Charlie and reports the plane’s altitude is 1,700 feet. Charlie’s eyes are 5.2 feet from the ground.
Answers
Answer 1
Answer:
X would be the ground distance from Charlie to the plane tan 32° = (1700-5.2) / x which would give you x = 2712.25 ft

Answers
A discrete variable is a variable which may take only certain discrete values; for example the number of people in a household is a discrete variable which may have the value 1, 2, 3, etc. but cannot have intermediate values such as 1.473 or 3.732. Choice d) can be represented by a discrete probability distribution, the other choices cannot be so represented.

Answer:
-x-4=9 ( find the x )
Answers
X=-13 Because 9 plus 4 is 13 but x can't be negative so you divide my negative 1 and get x=-13
You need to make x the subject. This means only x needs to be on one side of the equals sign. -x-4=9 you need to keep x positive so +x on both sides (because it is the opposite of minus) -4=9+x minus the nine on both sides (because it is the opposite of adding) -11=x This is the answer. -11=x
