If a(n) = (39n^4 -506n^3 + 2341n^2 - 4610n + 3416) / 8 then
<span>a(1) = 85 </span>
<span>a(2) = 17 </span>
<span>a(3) = 19 </span>
<span>a(4) = 4 </span>
<span>a(5) = 2</span>
<u>Given</u>:
Given that FGH is a right triangle. The sine of angle F is 0.53.
We need to determine the cosine of angle H.
<u>Cosine of angle H:</u>
Given that the sine of angle F is 0.53
This can be written as,
Applying the trigonometric ratio, we have;
----- (1)
Now, we shall determine the value of cosine of angle H.
Let us apply the trigonometric ratio , we get;
----- (2)
Substituting the value from equation (1) in equation (2), we get;
Thus, the cosine of angle H is 0.53
If you would like
to write the following in the math expression, you can do this using these
steps:<span>
<span>a number ... </span>n
eight less than four times a number ... 4 * n - 8</span>
<span>
is less than 56 ... < 56
4 * n - 8 < 56
4 * n < 56 + 8</span>
<span>4 * n < 64 /4</span>
<span>n < 64 / 4</span>
<span>n < 16</span>
The possible values of that number are less than 16.
