Answer:
0.592
Step-by-step explanation:
Total Number of Students =125
Out of these, 74 reported that they have completed their required English 101 course.
To find the best point estimate for the proportion of students at the college who have completed their required English 101 course, we divide the number of students who said "yes" by the total number of students.
The exact value of sin (π/3 + π) is: sin (4π/3) = -√3/2.
Here, we have,
To find the exact value of sin (π/3 + π), we can use the properties of trigonometric functions.
First, let's simplify the angle π/3 + π:
π/3 + π = (π + 3π)/3 = 4π/3
Now, we need to determine the reference angle within the unit circle for 4π/3.
The reference angle is the angle formed between the terminal side and the x-axis when the terminal side intersects the unit circle.
To find the reference angle for 4π/3, we subtract the nearest multiple of 2π from 4π/3:
4π/3 - 2π = (12π/3 - 6π)/3 = 6π/3 = 2π
Therefore, the reference angle for 4π/3 is 2π.
Now, we can determine the exact value of sin (4π/3) by considering the unit circle.
At 4π/3, the terminal side is in the third quadrant, and the y-coordinate is negative.
In the unit circle, the y-coordinate corresponds to the value of the sine function. Since the y-coordinate is negative, the exact value of sin (4π/3) is -√3/2.
Hence, sin (π/3 + π) = sin (4π/3) = -√3/2.

=2secA
Step-by-step explanation:
\begin{lgathered}LHS = \frac{cosA}{1+sinA}+\frac{1+sinA}{cosA}\\=\frac{cos^{2}A+(1+sinA)^{2}}{(1+sinA)cosA}\\=\frac{cos^{2}A+1^{2}+sin^{2}A+2sinA}{(1+sinA)cosA}\\=\frac{(cos^{2}A+sin^{2}A)+1+2sinA}{(1+sinA)cosA}\\=\frac{1+1+2sinA}{(1+sinA)cosA}\end{lgathered}
LHS=

1+1+2sinA
/* By Trigonometric identity:
cos² A+ sin² A = 1 */
\begin{lgathered}=\frac{2+2sinA}{(1+sinA)cosA}\\=\frac{2(1+sinA)}{(1+sinA)cosA}\\\end{lgathered}
=
(1+sinA)cosA
2+2sinA
=
(1+sinA)cosA
2(1+sinA)
After cancellation,we get
\begin{lgathered}= \frac{2}{cosA}\\=2secA\\=RHS\end{lgathered}
=

Therefore,
\begin{lgathered}\frac{cosA}{1+sinA}+\frac{1+sinA}{cosA}\\=2secA\end{lgathered}
