From the figure, it is downward parabola of the form 
The parabola has its vertex at 
Distance between parabola vertex and its directrix is 1 unit.
So, the value of a is 1
Hence, the equation of parabola is 
Answer:13years 7months 17 days
Step-by-step explanation:
1hr--->60min
116520hrs--->6.99120*10^6
convert hrs to days by dividing by 24
so you have 4855 days
divide it by 30 to get months which will be =161.833333 divide it by 12 to get yrs so you will get 13.48611111 then go ahead and subtract it to get the 13 years 7 months and 17 days
The circumference of the circle is equal to the perimeter of the triangle, then the area of the circle is 12 square units. Option D is correct.
<h3>What is a circle?</h3>
It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A triangle has sides that measure 2 units, 5 units, and 5.39 units.
The circumference of the circle is equal to the perimeter of the triangle. Then the radius of the circle will be

Then the area of the circle will be

Answer:
12+n
Step-by-step explanation:
8+n-4 = n+4
n+4 = n+4 (Can not be simplified).
(8+n)-4 = n+4
12+n = 12+n (Can not be simplified).
(8-4)+n = n+4
So the answer would be 12+n because it does not equal n+4.
