Answer:
tan45 = x over 1100
Step-by-step explanation:
Because tan = opposite/ adjacent
x is the opposite of the 45 angle in the figure shown
1100 is the adjacent of the 45 degree angle
thus tan45 = x/1100
I have included a graph to help you see what the domain and range would be
There are no minus y values.
0<y< infinity y is included in the reals.
The domain is
- infinity < x < infinity.
I don't want to say that either x or y can equal - or + infinity. Some teachers allow it. You have to ask your instructor what they will accept.
The blue line is y = 4^x
The red line is y = 2^x
The answer would be “-876”
(4-3n-5n2)
+( -2+n-3n2)

-2-2n-8n2
so for A it is 16 times as large because the area is 3*3 which is 9 but since it is a triangle the area is halved and is 4.5 and divide 72 by 4.5 which gives us 16
then for b I believe that the scale factor is 4
and for C it is asking for the bottom side of the scaled copy not of triangle A and 4*3=12 so the bottom is 12
ok now its complete =)
