Answer:
(sin x)^2*(sec x) is positive in QII
Step-by-step explanation:
(sin x)^2 is always 0 or positive. Here x lies in QII.
sec x is positive when the adjacent side is positive and negative when the adjacent side is negative. In QII the adjacent side is positive.
In summary, (sin x)^2*(sec x) is positive in QII
Answer:
d
Step-by-step explanation:
A segment joining the midpoints of a triangle is
• Parallel to the third side
• Half the length of the third side
The segment DF joins the midpoints of 2 sides of Δ ABC , then
BC = 2 × DF = 2 × 4 = 8
You just multiply each of the coordinates by the scale factor. No extra work since it’s from the origin.
Doing this gives:
J’ (2.5 , 10)
K’ (15 , 10)
L’ (15 , 2.5)
M’ (2.5 , 2.5)
Answer:
sorry dont know
Step-by-step explanation:
If a number in parenthesis is directly next to a number without, then the two numbers need multiplied.
-12(5/6)(-2/15) is an example of a double multiplication. But we'll multiply -12 and 5/6 first, then multiply the product by -2/15.
-12x5/6=14 2/5
14 2/5x-2/15=-1 23/25
