Let the interior angle be x.
x/(180-x) = 13/2
2x= 2340-13x
15x=2340
x=156
exterior angle= 180-156=24
Number of sides=360/24=15
15-sided polygon
Answer:
w ≤ 15
Step-by-step explanation:
A rectangle is shape with 4 sides where 2 pairs of sides are equal and form 4 perpendicular angles. 1 pair of sides is the width and is distance w. 1 pair of sides is the length and is 10 inches. The total distance around the shape is the perimeter. We know the perimeter is 50 inches or less. Add each side together and let it be less than or equal to 50. Then solve for w.
P ≥ l + l + w + w
50 ≥ 10 + 10 + w + w
50 ≥ 20 + 2w
30 ≥ 2w
15 ≥ w
Answer:
<h3>x1=-8;x2=8</h3>

Given:
Initial value of new car = $17,500
Depreciation rate = 4.6%
To find:
The value of car after 4 years.
Solution:
The exponential decay model is
where, a is initial value, r is decreasing rate and t is time in years.
Substitute a=17500, r=0.046 and t=4 in the above equation.
The value of car after 4 years is $14495.44.
Therefore, the correct option is D.
