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.

Answer:
The selling price that will maximize profit is $56.
Step-by-step explanation:
Given : It costs 12 dollars to manufacture and distribute a backpack. If the backpacks sell at x dollars each, the number sold, n, is given by
To find : The selling price that will maximize profit ?
Solution :
The cost price is $12.
The selling price is $x
Profit = SP-CP
Profit = x-12
The profit of n number is given by,
Substitute the value of n,
Derivate w.r.t x,
Put it to zero for critical point,
Derivate again w.r.t x, to determine maxima and minima,
It is a maximum point.
Therefore, the selling price that will maximize profit is $56.
