solve for:
sin (pi/4 -x) - sin (x + pi/4) for 0 < x < 2pi
Answer:
sin(pi/4 - x) - sin(x + pi/4) = 1
[tex] \frac{ \sqrt{2} }{2} ( \cos(x) - \sin(x) ) - \frac{ \sqrt{2} }{2} ( \sin(x) + \cos(x) ) = 1 \\ \\ < = > - 2 \times \frac{ \sqrt{2} }{2} \sin(x) = 1 \\ \\ < = > \sin(x) = \frac{ - 1}{ \sqrt{2} } \\ \\ < = > x = - \frac{\pi}{4} + k2\pi \: or \: x = \frac{5\pi}{4} + k2\pi[/tex]
but 0 < x< 2pi => x = { 5pi/4; 7pi/4 }

Answer:
[tex]\sqrt{29} ,6,2\pi ,3\sqrt{8}[/tex]
Step-by-step explanation:
Hello there!
First lets find the value of each irrational number
[tex]6 = 6\\\\\sqrt{29} =5.385164807\\\\2\pi =6.283185307\\\\3\sqrt{8} =8.485281374[/tex]
now we can easily put them in order from least to greatest
5.3, 6, 6.2, 8.4
then we change it to its irrational form
so the correct order would be
[tex]\sqrt{29} ,6,2\pi ,3\sqrt{8}[/tex]

Question 1Let number of adult tickets - x, student tickets - yRequired equations:
x + y = 87.25x + 5.50y = 52.75Solve by substitution x = 8 - y
7.25(8 - y) + 5.50y = 52.7558 - 7.25y + 5.50y = 52.751.75y = 5.25y = 5.25/1.75y = 3Find x:

Caden, Zoe, and Sophia shared a pizza. Caden ate 20 percent of the pizza. Zoe ate 50 percent more of the pizza than Caden ate. Noah ate 50 percent more of the pizza than Zoe ate, and Sophia ate the rest of the pizza. Find the percentage of the pizza that Sophia ate.
Answer:
Step-by-step explanation:
c=.2, z=1.5(.2), n=1.5(1.5).2
s+c+z+n=1
s+.2+1.5(.2)+1.5(1.5).2=1
s+.2+.3+.45=1
s+.95=1
s=.05
So Sophia ate 5% of the pizza
Answer:
Sophia ate 5%.
Step-by-step explanation:
Caden ate 20%. Zoe ate 50% more than him, so 150% of 20%. That is 20+half of 20, which is 30. So zoe ate 30%. Noah ate 50% more than her, so 150% of 30%, which is 45%. Add them together and get 95%. That leaves 5% for Sophia to eat.

Question isn't well formatted :
If I have 48 cards and and gave 10 to my friend and I have 38 left. what fraction of original number of card do I have left.
Answer:
0.7917
Step-by-step explanation:
If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards

Answer:
{-5/4, 8}
Step-by-step explanation:
We are given (4u + 5)(8 - u) = 0. Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:
4u + 5 = 0 leads to u = -5/4, and
8 - u = 0 leads to u = 8.
The solutions are {-5/4, 8}

Find the slope that passes through the two points. (9,3) and (6,7)
Answer:
m=4/-3
Step-by-step explanation:
the equation for slope (m) when given two points is (y2-y1)/(x2-x1)
we are given the points (9,3) and (6,7)
we can label the points:
x1=9
y1=3
x2=6
y2=7
now substitute into the equation
m=(7-3)/(6-9)
subtract
m=4/-3
the slope is 4/-3
