Step-by-step explanation:
y = log2 x
Convert to exponential form
x = 2^y
when x = 8 , 8 = 2^y so y = 3
x = 4 , 4 = 2^y so y = 2
the other values are found in the same fashion.
x = 2 , y = 1
x = 1 y = 0
x = 1/2, y = -1
Answer:128
Step-by-step explanation:
y+yx
When x=15, y=8
8+(15×8)
=8+120=128
Answer:
8
Step-by-step explanation:
Fourmla:
a^2+b^2=c^2
7^2=49
3^2=9
49+9=58
square root of 58 is about 8.
I believe the answer is C) 0
