Answer:
i. <DCB = 
ii. Sin of <DCB = 0.8
Step-by-step explanation:
Let <DCB be represented by θ, so that;
Sin θ = 
Thus from the given diagram, we have;
Sin θ = 
= 0.8
This implies that,
θ =
0.8
= 53.1301
θ = 
Therefore, <DCB =
.
So that,
Sin of <DCB = Sin 
= 0.8
Sin of <DCB = 0.8
Answer:
The First One
Step-by-step explanation:
Key Answer: 7×4=28 .
Answer:


Step-by-step explanation:
You have the following exponential expression:

You need to divide both sides of the equation by 2:

Now apply the function Natural logarithm to both sides of the function:

Note that now the exponential function is transformed into a logarithmic function.
By definition:
Because the base of the Natural logarithm is the Euler's number "e".
Then you can solve for "x":
)
I think the answer would be A.) If I is already 150 and K is 7. Now k is doubled and so that would mean I would as well! Hope this helps
