Answer:
The linear model means that there is a uniform increase and in this case of US population from 92 million people in 1910 to 250 million people in 1990
.
This means an increase of 250
−
92
=
158 million in 1990
-1910
=
80 years or
158
80
=
1.975 million per year and in x years it will become 92
+
1.975
x million people. This can be graphed using the linear function 1.975
(
x
−
1910
)
+
92
,
graph{1.975(x-1910)+92 [1890, 2000, 85, 260]}
The exponential model means that there is a uniform proportional increase i.e. say p
% every year and in this case of US population from 92 million people in 1910 to 250 million people in 1990
.
This means an increase of 250
−
92
=
158 million in 1990
−
1910
=
80 years or
p
% given by 92
(
1
+
p
)
80
=
250 which gives us (
1
+p
)
80
=
250
92 which simplifies to p
=
(
250
92
)
0.0125
−
1
=
0.0125743 or 1.25743
%
.
This can be graphed as an exponential function 92
×
1.0125743
(
x
−
1910
)
, which gives population in a year y and this appears as
graph{92(1.0125743^(x-1910)) [1900, 2000, 85, 260]}

Answer:
n = d+30 since he has 30 more nickels than dimes, to make them equal you have to add 30 to the dimes.
:
n+d = 150 substitute for n:
d+30+d = 150
2d = 120
d = 60 he has 60 dimes and 150-60 = 90 nickels

Answer:
D
Step-by-step explanation:
The question:
10^4= 10000
4^10=1048576
1048576x10000= 10485760000
4^5= 1024
10485760000/1024= 10240000
A. 262144 (NO)
B. 2.62144e+14 (NO)
C. 10000x1073741824= 1.0737418e+13 (NO)
D. 10000x1024= 10240000 (YES)
Hope this helps ^^
