Find the vertices and foci of the hyperbola with equation (x-5)^2/81 -(y-1)^2/144 = 1

vesna_86 [32]

Given the equation of an hyperbola in the form:
$\frac{(x-a)^2}{b^2}- \frac{(y-c)^2}{d^2}=1$
Then the focus of the hyperbola is $(\pm\sqrt {b^2+d^2},0)$
Compute like this:
$\sqrt{81+144}=15$
So the two focus points are $(\pm15,0)$
The vertices are given by the formula: $(\pm a,0)$
We deduce the two vertices of the given hyperbola: $(\pm9,0)$
since $\sqrt{81}=9$

The nth term of a sequence is 3n+5 to the 6th terms sequence

Maslowich

Answer:

Hey!

The 6th term of your sequence is 23!

Step-by-step explanation:

<u>This is how you get it...</u>

1) T6=3n+5 (the 6th term and the equation...)

2. We now do T6=3(6)+5 (3 x 6 then add 5)

3. In other words... T6=18+5

4. We work it out 18 + 5 = 23

HOPE THIS HELPS!!
