Answer:
4
Step-by-step explanation:
The length of WY = 24 - (-1) = 24 + 1 = 25. 1/5th of that is 5 so X must be -1 + 5 = 4.
As far as I can tell, that isn't a function at all.
x = 0 produces y = -2 and y = 4, which can't happen.
Please don't use all caps, that's really, really irritating.
Answer:x=12 and x=2
Step-by-step explanation:
2.2x-10=0.2x+14
2.2x-10-(0.2x+14)=0
2.2x-0.2x-14-10=0
2x-24=0
2x=24
x=24/2
x=12
-4x+5=x-5
-4x+5-(x-5)=0
-4x-x+5+5=0
-5x+10=0
-5x=-10
x=-10/-5
x=2
Answer: The top of the Crane is 31 feet above the ground.
Step-by-step explanation:
When it is fully extended, the crane arm forms a 30 degree angle with a line parallel to the ground. This means that a right angle triangle is formed. The length of the Crane's arm represents the hypotenuse. The horizontal distance represents the adjacent side of the right angle triangle. The distance, h of the top of the Crane from the ground represents the opposite side of the right angle triangle.
To determine h, we would apply
the Sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 30 = h/62
h = 62Sin30
h = 62 × 0.5
h = 31 feet
