the answer is C.
by the formula vertex (xv,yv) y=a(x-xv)²+yv
Sorry if this isn’t correct but I think its $11.9
Answer:
7740 degrees.
Step-by-step explanation:
The sum of the exterior angles of all polygons add up to 360 degrees.
So the number of sides and the number of interior angles in this polygon = 360 / 8 = 45.
Each internal angle = 180 - 8 = 172 degrees, so the sum of all interior angles
= 172 * 45
= 7740 degrees,
Answer:

Step-by-step explanation:
Independent events:
If two events, A and B are independent, the probability of both A and B happening is the same as the probability of A happening multiplied by the probability of B happenings, that is:

In this question:
The statement is 
3427 + 65.75s = 5000 + 35.5s
65.75s - 35.5s = 5000 - 3427
30.25s = 1573
s = 1573 / 30.25
s = 52 seconds <== they are the same at 52 seconds
3427 + 65.75(52) = 6846
5000 + 35.5(52) = 6846
and their altitude is 6846 <===
