Answer:
The question can be answered by using a Pythagoras' Theorem : to find the base of the pole to which each wire is attached to the ground.
Step-by-step explanation:
the base of the pole is represented by b.
the height of the pole is represented by a= 5 feet
the length of t he wire is represented by c=5 feet.
Thus, using the Phytagoras Theorem,
c^2=a^2+b^2,
or b=3.3.
Thus , each wire i attached by about 3.3 feet to the base of the pole.
Answer:
3.32ft
Step-by-step explanation:
The wire and the poles attached to the ground form a right triangle with the length of the wire being the hypotenuse.
Using Pythagoras Theorem:
Hypotenuse²=Adjacent²+Opposite²
6²=5²+x²
x²=36-25
x²=11
x=√11=3.32 ft.
The wires are attached 3.32 ft from the base of the pole on the ground

Your equation 
is in the form 
The vertex only relies on "a" and "b" though, so that +9 doesn't really matter in this case. The vertex of a parabola is located where
So your x-coordinate is -1. You need to find f(-1) to find your y-coordinate, and then you list it in the form (-1, y).

Answer:
$114,000
Step-by-step explanation:
Use formula
where
I = interst
P = principal
r = rate
t = time
First, find the interst for 25 years:
I = unknown
P = $190,000
r = 0.03 (3% as decimal)
t = 25
Now find the interest for 5 years:
I = unknown
P = $190,000
r = 0.03 (3% as decimal)
t = 5
The unpaid balance is
