This conic section is an ellipse.
Here: 2a = 10 ( the major axis ) and 2 b = 6 ( the minor axis );
and the formula is:
x² / a² + y² / b² = 1
So: a = 10 : 2 = 5 and b = 6 : 2 = 3.
x² / 5² + y² / 3² = 1
Answer:
The equation is: x² / 25 + y² / 9 = 1.
Answer:
B
Step-by-step explanation:
The sum to n terms of a geometric series is
= 
where a is the first term and r the common ratio
Here a = 6144 and r =
=
=
, then
= 
= 
= 12288(1 -
) ← distribute
= 12288 - 12
= 12276 → B
Answer:
4p(p)
Step-by-step explanation:
at first we write each one as a sequence
and find its equation
the first table
-19, -11, -3, 5
8x-19
the third table
15,12,9,6
-3x+15
the second table
-1. 5,1.5,3,4.5
+3 +1.5 +1.5
so the third table is the nonlinear function
