Coordinates of N are (-55, 6)
I got 8
because 16-8 equals 8
In standard form, -3(1-8x-2y) is:
DISTRIBUTIVE PROPERTY: 3+24x+6y
ANSWER: 24x+6y-3
64 divided by 4 is 16. The answer is 16 I believe!
Edit: I realized you were asking for the cost. That would be 48. 64 - 16 = 48.
To answer, determine first the length of the arc intercepted by the angle which measures 45°.
Calculate for the circumference of the circle with the equation,
C = 2πr
where C is circumference and r is radius. Substitute the known value for r,
C = 2π(7) = 43.98
Then, multiply the obtained value by the ratio of the angle intercepted and the whole revolution.
Arc = 43.98 x (45°/360°)
Arc = 5.5
The whole perimeter of the sector includes the arc and 2 radii. Hence, the equation for the whole perimeter is,
Perimeter = Arc + 2r
Substituting the values,
Perimeter = (5.5) + 2(7)
Perimeter = 19.50
<em>ANSWER: 19.50 units</em>
