Mathematics
1 answer:
Natalka [10]3 years ago
5 0

Answer:  B. ( -∞ , 0)   and   C. (1, 2)

<u>Step-by-step explanation:</u>

The y-value is increasing between x = -∞ and x = 0.

The y-value is decreasing between x = 0 and x = 1.

The y-value is increasing between x = 1 and x = 2.

The y-value is decreasing between x = 2 and x = +∞


So, the y-value is increasing at ( -∞ , 0) ∪ (1, 2)

18) If the straight line y=m X touches the circle (x - 2)^2 + (y - 6)^2 = 4, then m= ......
fenix001 [56]

Answer:

(8) d. 4/3    (9) a. (X - 4)^2 + (y-4)^2= 25

Step-by-step explanation:

8. CENTER OF CIRCLE: O (2,6)

     radius of circle : r = √4 = 2

if m = 4/3 line: y = 4/3 x

perpendicular distance (d) from center of circle to line y = 4/3 x is

d = |((4/3 x 2) + (-1) x 6)| / √((4/3)² + (-1)²) = |(-10/3)| / √(25/9) = (10/3) / (5/3) = 2

d = r means line touch with circle

9. center of circle is the intersection of the diagonals of rectangle (4,4) and its radius is 5 (illustrated)

the equation of circle: (X - 4)^2 + (y-4)^2= 25
