Answer: The correct option is (D) 196608.
Step-by-step explanation: We are given to find the value of the 9th term in the following geometric sequence :
3, 12, 48, 192, . . .
We know that
the n-th term of a geometric sequence with first term a and common ratio r is given by
For the given sequence, we have
first term, a = 3 and the common ratio, r is given by
Therefore, the 9th term of the given sequence will be
Thus, the required 9th term of the given sequence is 196608.
Option (D) is CORRECT.
Answer:
Step-by-step explanation:
The standard equation of a parabola is
y² = 4ax
where, a is the focus,
The coordinates of the centre of parabola is (0,0)
coordinates of focus is (a, 0)
It is symmteric about the x axis
the equation of directrix is x = -a.
Answer:
1.5 mile an hour
Step-by-step explanation:
<u>400,00</u> Because
150,00 + 150,00 = <em>300,00</em>
300,00 + 150,00 = 400,00
150,00 x 3
Answer:
y = -5
Step-by-step explanation:
The coordinate point is in the format (x, y)
Therefore, the y-value of (4, -5) is -5
So the equation of the horizontal line is therefore y = -5
