Answer:
1. $503.08
2. 5071
Step-by-step explanation:
1. Perimeter = (pi × r) + d
= (3.14 × 27/2) + 27
= 69.39
Cost: 69.39 × 7.25 = $503.0775
2. 17 × (pi × d)
17 × 3.14 × 95
5071.1 feet
Answer:
And then the rectangular coordinates for this case are :
Step-by-step explanation:
We have the following point given 
and we want to conver from polar to rectangular coordinates and we need to use the following formulas:
For this case we have that:
And:
Replacing we got:
And then the rectangular coordinates for this case are :
I think 1,000,000 or 800,000
Answer:
a) (3, -4), (2, 4), (-5, -6)
b) (4, 3), (-4, 2), (6, -5)
Step-by-step explanation:
a) Reflection in the x-axis negates the y-coordinate:
(x, y) ⇒ (x, -y)
(3, 4) ⇒ (3, -4)
(2, -4) ⇒ (2, 4)
(-5, 6) ⇒ (-5, -6)
__
b) Reflection in the line y=x swaps the x- and y-coordinates:
(x, y) ⇒ (y, x)
(3, 4) ⇒ (4, 3)
(2, -4) ⇒ (-4, 2)
(-5, 6) ⇒ (6, -5)
