Answer:
the simple interest is <em>36.</em>
Step-by-step explanation:
To find the answer we will first<em> divide 3 by 100</em> and we get <em>0.03.</em> Now <em>multiply 0.03 by $200</em>, which is<em> 6</em>. Then <em>multiply 6 by 6</em> <em>months</em> and we get 36. Therefore, <em>36 is our answer. </em>
E. 1/2
With trig functions, multiple x values correspond with the same y value.
Using an initial x value (the principle value), we can find other x values for the same y value, this is what we are are being asked to find in this question.
There are slightly different ways to find these x values (also known as solutions) for each of the basic trig functions.
The x values are in degrees for the basic trig functions.
For cosine, the rule is as follows:
360 - principle value;
this will give what I, personally, like to think of as a secondary principle value (this value is not actually recognised as a secondary principle value, I just like to think of it as such). Anyway, all other solutions can the be found by adding or substrating any integer multiple of 360 to/from the PV and 'secondary PV'.
For your question:
cos60 = 1/2
60 is the x value (PV)
so...
360 - 60 = 300 is the 'secondary PV'
Just to be clear, this means that if I were to find the cos300, I would get 1/2.
That is sufficient for explaining the answer to this particular question but if you wanted to find any other solution, you would just have to do either:
60 + or - n(360)
or...
300 + or - n(360),
where n = any integer
Answer:
D and F
Step-by-step explanation:
can be rewritten as 
.
From there you can use the quadratic formula 
(ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.
Then you get 
Then you get 
So 
Which means 
or 
which are choices D and F.
