Answer:
23.6 (approximate value)
Step-by-step explanation:
- a*a+b*b=c*c Pythagorean thereom
- (21.5)^2 + b*b = (31.9)^2
- b*b= 1017.61 - 462.25
- √b*b= √555.36
- b=23.6(approximate value)

Answer: He cannot see a ship that is 4.5 miles away.
Step-by-step explanation:
Since we have given that

Here, h is the eye level above the water
d is the distance away.
If h = 12 feet
We will get :

Hence, it is 10.39 feet away when eye level is 12 feet above the water.
Therefore , he cannot see a ship that is 4.5 miles away.
It is given in the question that
Suppose the supply function for product x is given by

And we have to find how much of product x is produced when px = $600 and pz = $60.
And for that, we have to substitute 600 for px and 60 for pz, and on doing so, we will get

And that's the required answer .
Step-by-step explanation:
