Over which interval(s) is the function decreasing?
Let h represent height of mast.
We have been given that a from the top of a mast on a sailboat is attached to a point 19 feet from the mast. The rope is 28 feet long. We are asked to find the height of the mast.
The mast will form a right triangle with rope and sailboat as shown in the attachment.
Now we will use Pythagoras theorem to solve for h as:
Now we will take positive square root of both sides as:
Upon rounding to nearest tenth of a foot, we will get:
Therefore, the mast is approximately 20.6 feet tall.

Answer:
You would get $40.52 back.
Step-by-step explanation:
1.50+1.99+5.99
$9.48
50-9.48=40.52
You would get $40.52 back.
Answer:
8 cm
Step-by-step explanation:
The formula of circumference is c= πd------(1)
where C = circumference, π = 3.14 and d = diameter
as we know that diameter is equal to d= 2r
put the diameter formula in eq(1)
we get c= π2r-------(2)
from eq (2) separate r means radius
hence, r= c/(π2)------(3)
put the values in eq(3)
and radius is equal to 8 cm.
