3. There is only one at 360 degrees
4. there are 6 rotational symmetries and the number of reflectional symmetries would be 6 as you can see:
Answer:
<h2>X greater-than 0</h2>
Step-by-step explanation:
The given function is

Which is a logarithm function. An important characteristic of logarithms is that their domain cannot be negatice, because the logarithm of a negative number is undefined, the same happens for x=0.
Therefore, the domain of this function is all real numbers more than zero.
The image attached shows the graph of this function, there you can notice its domain restriction.
So, the right answer is the first choice: x greater than 0.
Answer:
( 1/3, 5 2/3) Or (0.33, 5.66)
Step-by-step explanation:
If you graph the 2 equations and see where they intersect, they will land on the answer.
Answer:
the answer is 2
Step-by-step explanation:
Answer:
Point Q = (3.6, 1.4)
Step-by-step explanation:
The 4:1 ratio should first be changed to 4/5.
y2-y1= 2+1 = 3 which as a fraction is 3/1, now multiply that which the earlier fraction 4/5 to get 12/5 = 2.4
x2-x1= 4-2= 2 which as a fraction is 2/1, do the same as earlier, multiply by 4/5 to get 8/5 = 1.6
now add these to A to get point Q
2+1.6= 3.6
-1+2.4=1.4
Point Q = (3.6, 1.4)
