Area of a circle = (pi)r^2
diameter is twice the radius, so radius = 8 ft
Area = (pi)(8)^2
= 64(pi)
= 201.06 ft

Find the slope of the line through each pair of points.<br> (2, -4), (5,-8)

slega [8]

Answer:

$m=-\frac{4}{3}$

Step-by-step explanation:

$Slope=m=\frac{y_2-y_1}{x_2-x_1}$

Here

$(x_1, y_1)=(2, -4) \ \ and \ \ (x_2, y_2)=(5, -8)$

$m=\frac{-8-(-4)}{5-2}$

$m=-\frac{4}{3}$

Describe in a complete sentence the solution set for 3x + 3 = 3+ 3x.

Answer:

<em>It has infinitely as many solutions</em>

Step-by-step explanation:

Equations and Identities

When dealing with equations, we must find values of the variable who mak the expression become an identity.

The expression is an identity regardless on what the value of x is, so we can say the equation has infinite as many solutions. For example x=0 will make the expression look like 3=3 which is an identity. If x=8, we'll obtain 27=27 and so on

Select a setting so that each given point will lie within the viewing window.

NemiM [27]

Answer:

The given points are

$(-13,3)\\(0,0)\\(-2,-7)$

The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.

The given maxium horizontal coordinate is 0.

The given minimum horizontal coordinate is -13.

The given maximum vertical coordinate is 3.

The given minimum vertical coordinate is -7.

Now, we extend each maximum and minimum value by 2 units to create the setting.

So, the setting is

$x_{min}=-15\\x_{max}=2\\ y_{min}=-9\\y_{max}=5$

With a scale of 2 units.
