Answer:
1 x 0.28 works, along with 5 x 0.056.
Answer:
B
Step-by-step explanation:
As the graph approaches positive infinity along y-axis, it goes both negative and positive directions along the x-axis.
Answer:
False
Step-by-step explanation:
It is false because the graph of 
does not passes through the point 
.
x = 16
y = 4
Substitute
Since 4 is not equal to 256, the answer is false.
By using The half-angle formula
cos X/2 = ±√[(1 + cos X)/ 2]
But we have cos x=2/3
= ±√[(1 + 2/3)/ 2]
= ±√[(5/3 )/ 2]
= ±√[(5/5]
=±√1
Therefore answer is ±1
cos A/2 = ±√[(1 + cos A )/ 2]
