Answer:
the answers are 12.5, 5, 2, 0.8 and 0.32
Step-by-step explanation:
2(0.4)^-2
=2(6.25)
= 12.5
2(0.4)^-1
= 2(2.5)
=5
2(0.4)^0
=2(1)
=2
2(0.4)^1
=2(0.4)
=0.8
2(0.4)^2
=2(0.16)
=0.32
Answer:
No.
Step-by-step explanation:
3/4 is not less than 2/10.
3/4 = 15/20
2/10 = 4/20
15/20 > 4/20
Answer:
C
Step-by-step explanation:
The domain of this function is ![[-4,2]](https://tex.z-dn.net/?f=%5B-4%2C2%5D)
, as it is shown in the graph that 
is only within this interval. The range of this function is ![[-4,4]](https://tex.z-dn.net/?f=%5B-4%2C4%5D)
, as the smallest value of 
is -4 and the largest value of is 4, and takes every possible values between them.
Set them equal to each other and solve
3x + 39 = 4x +34
-x=-5
X=5
Plug it in
3(5) + 39 = 54
4(5) +34 = 54
For the final angle ,
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72
