Answer:
1/19
Step-by-step explanation:
3(7) -2 = 19, this would be g(7) but they want g^-1 (7) so you need the inverse of your answer:
1/19.
HOPE THIS HELPS & MAKES SENSE!!!
Answer:
Question 13. I believe is C.
Step-by-step explanation:
take your area of the face you are given aka your 7 5/6 and multiply it by six since there are six faces.
You can convert the mixed number to an improper fraction
= denominator times the whole number ( 6x7)= then add the numerator (42+5)=
Then multiply by six to get your answer
I'm not completely sure about question number fourteen so I am not answering it.
The answer is y= — 1/2x + 3
Answer:
,
Explanation:2√2 sin(q) + 2 = 0
2√2 sin(q) = -2
sin(q) =

sin(q) =

Now, we know that:
sin (45) =

From the ASTC rule, we know that the sine function is negative in the third and fourth quadrant.
This means that:
either q = 90 + 45 = 135° which is equivalent to

or q = 270 + 45 = 315° which is equivalent to

Hope this helps :)
Check the picture below
the triangles are similar, the angles are congruents then
so... just add them up, and divide by 2, or set them as rational
