112 Seats/ 7 Seats= 16 Total Rows
70Seats / 7Seats = 10 Full Rows
16-10=
6 Remaining Rows that tell us that there are a total of 42 empty seats.
The angle that defines the arc is 1.57 radians or 90°.
<h3 /><h3>How to get the angle of the arc?</h3>
For a circle of radius R, the length of an arc defined by an angle θ in radians is given by:
L = θ*R.
Here we know that the radius is R = 7cm, and the length of the arc is 10.99 cm. Replacing these in the above equation:
10.99 cm = θ*7cm
θ = (10.99 cm/7 cm) = 1.57
Then the angle is 1.57 radians. Remember that:
3.14 radians = 180°
Then:
θ = (1.57/3.14)*180° = 90°

Answer:
The last choice is the correct answer.
Step-by-step explanation:
I graphed the last equation on the graph below.
Answer is 0.89 sorry for bad drawing and putting 89 as the answer instead of 0.89
Answer: True
Solution:
Rearrange the equation to the LHS:
[x^2 + 8x + 16] · [x^2 – 8x + 16] - (x^2 – 16)^2 = 0
Factoring x^2+8x+16
x^2 - 4x - 4x - 16
= (x-4) • (x-4)
= = (x+4)2
So now we have an equation
(x + 4)^2 • (x - 4)^2 - (x^2 - 16)^2 = 0
Step 2: Evaluate the following:
(x+4)2 = x^2+8x+16
(x-4)2 = x^2-8x+16
(x^2-16)2 = x^4-32x^2+256
(x^2+8x+16) (x^2-8x+16 ) - (x^4-32x^2+256 )
0 = 0
Hence True
