Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become
we can arrange this properly to form a quadratic equation by grouping like terms.
solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft
Answer:
Step-by-step explanation:
we know that
The measure of central angle ABC is radians
so
subtends the complete circle
The area of the shaded sector is the area of a quarter circle
so
The area of a quarter circle is equal to
we have
substitute
Answer:

Step-by-step explanation:
(a)
Consider the denominator
To obtain 5xy from x , multiply by 5y
Thus numerator is multiplied by 5y, that is
=
(b)
Consider the numerator
To obtain 5ab² from ab, multiply by 5b
Thus denominator is multiplied by 5b, that is
=
