199 + 100 = 299 (original price)
100 / 299 = 0.334 = 33.4% off
Answer:
16П or approximately 50.3)
Step-by-step explanation:
The area of a circle is equal to П*r²
Since the circle is inside a rectangle with side that is equal to 8, we know that d = 8
2r = d
r = 8/2
r = 4
A = П*r²
A = П*16
А = 16П ( or 16*3.141592653589793238... = 50.26548... ≈ 50.3)
The length of the parametric curve (call it <em>C </em>) is given by

We have


Now,

so that the arc length integral reduces to

which has an approximate value of 53.4596.
Answer:
true
Step-by-step explanation:
Answer:
b)Add the equations to eliminate x.
Step-by-step explanation:
y= x+20
y= - x+2
Result of the addition: (-x cancels x)
2y = 22
y =11
11=x +20 -9 = x
11=9+2
11 = -9 +20
