Identify the equation that represents a proportional relationship.
1 answer:
Answer:
c.
Step-by-step explanation:
I'd generally say this would depend on what your definition of proportional is, but there's still one clear answer in this case regardless.
Here, a direct proportional relationship will pass through (0, 0), meaning it will not have a y-intercept and y will be 0 when x is 0.
Because b is the y-intercept, C is the answer as it is the only answer that does not have one.

Answer:
Therefore the height of the tower is 116.75 m.
Step-by-step explanation:
Given that a pole that is 2.6 m tall casts a shadow that is 1.03 m long.
Here the height of a object directly proportional to the shadow. It means
Height of the object ∝ shadow
Height of the object= k.shadow
[k is the proportional constant.]
[Height of object is denoted by h and shadow is denoted by s]
Then,
[h₁ is the height of the pole and s₁is the length of the shadow]
Again for the tower
[h₂ is the height of the tower and s₂ is the length of the shadow]
Therefore,
............(1)
Given ,
and
Putting the value of and
equation (1)
[cross multiplication]
Therefore the height of the tower is 116.75 m.
