Let
x---------> the thickness of the frame in feet
At-------> Area of the mirror and the frame in square feet
we know that
------> equation 
--------> equation 
equate equation
and equation 

therefore
the answer is the option

ITS B OR 92 DEGREES enjoy!!!
We have that
<span>y = -x</span>²<span>+8x
we know that
when the ball hint the ground is the x-intercepts of the graph
the x-intercepts is for y=0
so
0=-x</span>²+8x--------> x²-8x=0----> x*(x-8)=0
the solution is
x=0
x=8
the x intercepts are the points (0,0) and (8,0)
the distance between the x intercepts points =[8-0]-----> 8 ft
the answer is
8 ft
see the attached figure
Answer:
Jack's linear speed is 126ft/min
Bob's linear speed is 176ft/min
Step-by-step explanation:
First of all, find the circumference of both circles given the radius; Jack, 2<em>pi</em>r (10)=63ft. Bob 2<em>pi</em>r(14)=88ft. Now, realize that the merry go round revolves 2 times per min; 2rpm, so multiply each result by 2 and there you go.
