Answer:
36 movies.
Step-by-step explanation:
45
+
2.50
x
=
3.75
x
Here
x
=
NUMBER OF MOVIES
45
=
Annual rate
2.50
=
price of movie with annual fee
3.75
=
price of movie with no fee
Now we solve for
x
. Move
x
to one side by subtracting
2.50
x
on each side
45
=
1.25
x
We want
x
by itself, so divide
45
by each side.
45
1.25
=
x
x
=
36
Given:
The radius of the circle is 17 in.
Central angle of intercepted arc is 0.7 radians.
To find:
The length s of the intercepted arc.
Solution:
The formula for the length of intercepted arc is:
Where, r is the radius of the circle and 
is the central angle in radians.
Substituting 
in the above formula, we get
Therefore, the length of the intercepted arc is 11.9 inches.
X^2+4x+4=8
-8 -8
subtract 8 from both sides
x^2+4x-4=0
now factor using quadratic formula
ax^2+bx+c=0
x= -b +-[ (sqrt (b^2-4ac))/2a ]
x=-2(1+sqrt(2))
x= 2(sqrt(2) -1)
hope that helps, hopefully you know how to plug and chug into quadratic formula. if not you can ask for help
Answer:
Definitely Function B
Step-by-step explanation:
Because when you solve the equation it intercepts the X axis
Sum of square of two sides must be equal to the square of third side.
