Answer:
Option 2: y = ±sqrt(
)
Step-by-step explanation:
y = 7x^2 - 10
To find the inverse of a function, you must swap the y and x.
x = 7y^2 - 10
Now I will just simplify to have y by itself on the left hand side.
x + 10 = 7y^2
=y^2
sqrt(
)=±y
y = ±sqrt(
)

Given:
A circle with diameter 9 cm.
To find:
The area of the circle.
Solution:
The area of a circle is:
...(i)
Where r is the radius.
We know that, the diameter of a circle is twice than its radius.
The diameter of the given circle is 9 cm.


Substituting
in (i), we get




Therefore, the area of the given circle is 63.6.
