Quadrant is III so, sign would be negative for Sec.
Now, we know, csc = H / P
So, H = 4, P = 3
Calculate for B,
B² = H² - P²
B² = 4² - 3²
B² = 16 - 9
B = √7
We know, sec Ф = H / B = 4 / √7
We can write it as: -4√7 / 7 [ -ve sign for 3rd quadrant ]
In short, Your Answer would be Option B
Hope this helps!
D is in the correct order
Rise over run
-3+5=2
2+5=7
7+5=12
___________
Then you go by to 2 on the y
2/5 is the slope
Answer:
x ≤ -
Step-by-step explanation:
Given
3x + 14 ≤ 13 ( subtract 14 from both sides )
3x ≤ - 1 ( divide both sides by 3 )
x ≤ -
First multiply 12 by 8 to get 96
that is the total amount of seats including the broken ones. then multiply 3 by 4 to get the section of broken seats. 3 being the amount of rows that have broken seats an 4 is the amount of broken seats per row. you wind up with 12 broken seats.
Now subtract 12 from 96 to get 84 functional seats
