Answer:
x^2 + y^2 = 12
Step-by-step explanation:
For a circle with the center at the origin [(h,k) is (0,0)]
use the formula:
x^2 + y^2 = r^2
In this case r is 2sqroot3.
(2sqroot3)^2 is 12.
2•2•sqrt3•sqrt3
= 4•3
= 12
So we get,
x^2 + y^2 = 12
 
        
             
        
        
        
It is said that 85% of the students liked reading mystery stories. This means the remaining 15% don't like to read these stories. If there are 30 students belonging to the second category, then the number of students who liked reading mystery stories is (30/0.15)*0.85 equal to 170 students out of 200 students.
        
             
        
        
        
Answer:
opiton b
Step-by-step explanation:
To find out which equation satisfies h(x) we need to check with each option
We plug in x  value
A) h(–1.25) = –0.5
Plug in -1.25 for x  in h(x) = 16^x
That is not true
B) h(–0.5) = 0.25
Plug in -0.5 for x  
That is true.
C)  h(0.75) = 12
Plug in 0.75 for x  
That is not true.
D)  h(1.25) = 20
Plug in 1.25 for x  
That is not true
