Question 3 (Essay Worth 4 points)
Find the exact value by using a half-angle identity.
tan (7π/8)
Answers
Answer:
[tex]\displaystyle \tan \left(\frac{7\pi}{8}\right) = -\left(2 + \sqrt{2}\right)[/tex].
Step-by-step explanation:
Assume that the following are known:
The tangent half-angle identity: [tex]\displaystyle \tan\left(\frac{\theta}{2}\right) = \frac{1 - \cos(\theta)}{\sin(\theta)}[/tex].The sine and cosine of [tex]\displaystyle \frac{\pi}{4}[/tex]: [tex]\displaystyle \sin\left(\displaystyle \frac{\pi}{4}\right) = \frac{\sqrt{2}}{2}[/tex], [tex]\displaystyle \cos\left(\displaystyle \frac{\pi}{4}\right) = \frac{\sqrt{2}}{2}[/tex].The trigonometric identities for the sine and cosine of supplementary angles: [tex]\sin(\theta) = -\sin(2\pi - \theta)[/tex] and [tex]\cos(\theta) = \cos(2\pi - \theta)[/tex].The angle in question [tex]\displaystyle \frac{7 \pi}{8}[/tex] isn't very well-known. However, note that:
[tex]\displaystyle \frac{7 \pi}{8}[/tex] is equal to one-half times the angle [tex]\displaystyle \frac{7\pi}{4}[/tex];[tex]\displaystyle \frac{7\pi}{4}[/tex] is equal to [tex]2\pi[/tex] minus [tex]\displaystyle \frac{\pi}{4}[/tex], which is an angle with known sine and cosine values.Since the angle [tex]\displaystyle \frac{7\pi}{4}[/tex] is equal to [tex]\displaystyle 2\pi - \frac{\pi}{4}[/tex], its sine and cosine can be found from the sine and cosine of [tex]\displaystyle \frac{\pi}{4}[/tex] using the trigonometric identities [tex]\sin(2\pi - \theta) = -\sin(\theta)[/tex] and [tex]\cos(2\pi - \theta) = \cos(\theta)[/tex]:
[tex]\displaystyle \sin\left(\frac{7\pi}{4}\right) = -\sin\left(2\pi - \frac{7\pi}{4}\right) = - \sin\left(\frac{\pi}{4}\right) = - \frac{\sqrt{2}}{2}[/tex].[tex]\displaystyle \cos\left(\frac{7\pi}{4}\right) = \cos\left(2\pi - \frac{7\pi}{4}\right) = \cos\left(\frac{\pi}{4}\right) = \frac{\sqrt{2}}{2}[/tex].Apply the tangent half-angle identity to find the tangent of [tex]\displaystyle \frac{7 \pi}{8}[/tex]:
[tex]\begin{aligned}\tan\left(\frac{7\pi}{8}\right) &= \tan\left(\frac{7\pi/4}{2}\right) = \frac{1 - \cos(7\pi/4)}{\sin(7\pi/4)} \\ &= \frac{1 - \left(\sqrt{2}/2\right)}{\sqrt{2} / 2} = \frac{2 - \sqrt{2}}{\sqrt{2}} = \frac{\left(\sqrt{2}\right)^2 - \sqrt{2}}{\sqrt{2}} = \sqrt{2} - 1 \end{aligned}[/tex].

a) y= 2x+3
b) y= 1/2x+3
c) y= 1/2x-3
d) y=-2x-3
Answers
Answer:
B
Step-by-step explanation:
Since the line in the picture rises 1 unit for every 2 units it moves to the right, it has a slope of 1/2. Also, since it intersects the y axis at (0,3), the y intercept is 3. Therefore, the equation of the line is y=1/2x+3, or answer choice B. Hope this helps!
The diagram shows 3 vertices of a parallelogram.
Plot the 3 possible points for the 4th vertex.
Answers
Answer:
(-1, -1), (-3,5), (5, -3)
Step-by-step explanation:
(-1, -1) is the 4th vertex.
Which is the required vertex ?Let, 4th vertex is (x, y)
Given vertices of parallelogram are (-2. 2), (1, 1), (2, -2)
Here, (-2. 2) & (2, -2) are opposite vertices.
So, Midpoint of diagonals = [tex][(\frac{-2+2}{2}) ,(\frac{2-2}{2})][/tex] = (0, 0)
This is also midpoint of diagonal with vertices (1, 1) & (x, y)
So, (1+x)/2=0 ⇒ x = -1
& (1+y)/2=0 ⇒ y = -1
∴ 4th vertex is (-1, -1)

What is the domain of the function Y= In(x+ 2)?
x <-2
XX-2
x <2
X> 2
Answers
Answer:
x > -2
Step-by-step explanation:
Domain is the range is of all possible value for x in y= f(x) .
Domain of logarithmic function log(x) is given by x > 0.
It means any value can greater than x can be plugged in place of x in function log(x).
In the given function Y= In(x+ 2). In place of x there x+2 .
Thus x+2> 0
subtracting -2 from both sides
=> x+2 -2> 0-2
=> x > -2
Thus, domain of the function Y= In(x+ 2) is x > -2

Answer:
r =5
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2
The legs are r and 12
The hypotenuse is (8+r)
r^2 + 12^2 = (8+r)^2
r^2 + 144 = 64 + r^2 +16r
Subtract r^2 from each side
144 = 64 +16r
Subtract 64 from each side
144-64 = 16r
80 = 16r
Divide each side by 16
80/16 = 16r/16

To get onto the Honor Roll, Max has to get an average in math of at least a 90.
For five exams, he has an average of 88. What must he score on the next exam
to bring his average up to exactly 90?
Answers
Answer:
He needs to score 100 in his next test.
Step-by-step explanation:
The average of the exams is given by the sum of each exam score divided by the number of exams he took, therefore his prior average is:
[tex]\text{prior average} = \frac{\text{prior sum of grades}}{\text{prior number of tests}}[/tex]
Since he took five exams and had an average of 88, then his prior sum of grades is:
[tex]\text{prior sum of grades} = 88*5 = 440[/tex]
He needs to score "x" in his next test in order to have an 90 average, therefore if we add "x" to the sum of his grades and add 1 to the prior number of tests then equal that to 90, we can solve for "x". We have:
[tex]\text{desired average} = \frac{\text{prior sum of grades} + x}{\text{prior number of texts}+1}\\90 = \frac{440 +x}{6}\\440 + x = 90*6\\x = 540 - 440\\x = 100\\[/tex]
He needs to score 100 in his next test.
