Answer:
a) see the attached file
b) Coordinates of vertex = (0, 4)
Step-by-step explanation:
Given:
Focus of parabola is and the directrix is
To sketch: the parabola
To find: coordinates of the vertex
Solution:
As the focus lies on the y-axis and y-coordinate of the focus is positive,
equation of parabola is
Here, denotes the vertex of parabola, focus is and the directrix is
According to question,
So,
On adding these equations,
Put in
So, equation of parabola is
For part a), see the attached file.
b)
Coordinates of vertex =
Answer:
No
Step-by-step explanation:
4 to the 7th power is 4x4x4x4x4x4x4 (4 multiplied by itself 7 times) And 7 to the 4th power is 7x7x7x7 (7 multiplied by itself 4 times)
Answer:
Take the starting point as the first natural number that is 1.
Step-by-step explanation:
To find: a starting point so that the first 5 numbers in the sequence are all positive
Solution:
Natural numbers are numbers that are used for counting.
Natural numbers are basically positive integers.
Take the starting point as the first natural number that is 1.
The next point as 2.
The next point as 3.
The next point as 4.
The next point as 5.
So, the sequence becomes so that the first 5 numbers in the sequence are positive.
