A balloon has a circumference of 28 in. Use the circumference to approximate the surface area of the balloon to the nearest squa
Soloha48 [4]
C=2πr

r=C/(2π), now the surface area is:

A=4πr^2, using r found above we have:

A=4πC^2/(4π^2)

A=C^2/π, we are given that C=28 so:

A=28^2/π in^2

A=784/π in^2

A≈250 in^2 (to nearest square inch)

Find the coordinates of the midpoint M of ST. Then find the distance between points S and T. Round the distance to the nearest
ololo11 [35]

Answer:

Step-by-step explanation:

M is the midpoint

=>\left \{ {{x=\frac{6+7}{2} } \atop {y=\frac{-3-2}{2} }} \right

⇔\left \{ {x=\frac{13}{2} } \atop {y=\frac{-5}{2}}} \right.

⇒M(\frac{13}{2};\frac{-5}{2})

ST=\sqrt{(7-6) ^{2} +(-2+3)^{2}=\sqrt{2}=1.414

Which table does NOT represent a linear function
topjm [15]

TABLE D does NOT represent a linear function

<h2>Explanation:</h2>

The Table is shown below. Each table is a relationship between two variables, namely x and y. By plotting each table in a graphing tool we get:

TABLE A, FIRST FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{8-5}{-1-0} \\ \\ m=-3

TABLE C, SECOND FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{5-10}{-1-0} \\ \\ m=5

TABLE C, THIRD FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{1-2}{-1-0} \\ \\ m=2

TABLE D, FOURTH FIGURE:

It is not a linear function. It is likely this is a parabola that opens downward.
