Answer:
Step-by-step explanation:
The inverse of
y
=
2
x
is
y
=
log
2
x
Explanation:
This is how to do it.
From the given
y
=
2
x
interchange the variables so that
x
=
2
y
then solve for y:
x
=
2
y
take the logarithm of both sides with base
=
2
log
2
x
=
log
2
2
y
log
2
x
=
y
and
y
=
log
2
x
The graph of
y
=
2
x
and its inverse
y
=
log
2
x
. They are symmetric with the line
y
=
x
graph{(y-2^x)(y-log x/log 2)(y-x)=0[-20,20,-10,10]}
God bless....I hope the explanation is useful.
Answer:
0,3,8,15
Step-by-step explanation:
f(n)=n^2-1
The first term is
f(1) = 1^2 -1 = 1-1 =0
The second terms is
f(2) = 2^2 -1 = 4-1 = 3
The third term is
f(3) = 3^2 -1 = 9-1 =8
The fourth term is
f(4) = 4^2 -1 = 16-1 =15
Answer:
0.12 g/cm³
Step-by-step explanation:
Density is the ratio of mass to volume. The volume of the brownie is the cube of its side dimension:
V = s³ = (5 cm)³ = 125 cm³
Then the density is ...
ρ = M/V = (15 g)/(125 cm³) = 0.12 g/cm³
The density of the brownie is 0.12 g/cm³.
