Answer:
This is a curve linear would show the turning points clearly.
With bar graph we can also show changes but not turnng points a sthe description shows.
Step-by-step explanation:
In the context of curve fitting, a linear curve is a curve that has a linear dependence on the curve parameters. Examples of linear curves are: lines, polynomials, so where they increase the points can also show a line of fit where least amounts would stand out below the line of fit.
This is a systems of equations.
s = stamp, e = envelope

Substitute e + 9 for s.
.1(e + 9) + .13e = 2.51
Simplify.
.1e + .9 + .13e = 2.51
Simplify.
.14e + .9 = 2.51
Subtract .9 from both sides.
.14e = 1.61
Divide both sides by .14.
e = 11.5
Now, you can input e into the other equation.
11.5 + 9 = s
Simplify.
20.5 = s
s = 20.5, e = 11.5
Answer:

Answer:
pi= 3.14159
r= half of diameter , it is 4
h= 20
v= pi (4) ^2 (20)
Step-by-step explanation:

Here we go ~
As we can see in the figure, lines m and n are parallel to each other. so we can apply Angle pair properties ~
So,

[ they form corresponding angle pair ]
and it's given that :

therefore, by using above information. we can conclude that :
