Answer:
8
Step-by-step explanation:
f(x) = (x+2)(x-2)
Substituting x=1 into f(x):
f(1) = 3*-1
= -3
Since -2 & 2 touch the x-axis, 1 has a negative y value, 2 has a y value of 0, and all values from 2, are positive.
Hence,
3, 4, 5, 6, 7, 8, 9, 10 are all positive. Therefore, the answer is 8
This can be confirmed with a graph, as attached below.

Answer:
$ 5200
Step-by-step explanation:
int = money . time . rate
int = 90000 . 4/12 . 14/100
int = 900 . 1/3 . 14
int = 300 . 14
int = 5200
Given :
Center of circle, C = ( 1 , 5 )
Point on circle, P = ( 5 , 1 )
To Find :
The radius of a circle.
Solution :
We know, radius of circle is the distance between center and point of circle.
Distance between two points A(p,q) and B(r,s) is given by :

So, distance between the points (1, 5) and (5, 1) is :

Therefore, radius of circle is 5.66 units.
Hence, this is the required solution.
