Answer:

Step-by-step explanation:

d = c/pi

so d = 62.8/pi

    d = 62.8/pi or appr 19.99in

r = d/2

so r = 62.8/2pi or 31.4/pi appr 19.99/2

a = \pi  r^{2}

so

a = \pi *(31.4/\pi)^2

then

a = 985.96/pi

so

a = approximately 313.84

answer is rowan

Algebraically manipulating the formula FV = P +Prt, find the time period in years (to the nearest whole year) it would take to q
ICE Princess25 [194]

Answer:

55years

Explanation:

According to the given expression

FV = P +Prt

P is the initial deposit = $1000

FV is the future value = 4(1000) = $4000

r is the rate = 5.5% = 0.055

Required

Time t

Substitute the given values into the expression as shown;

FV = P +Prt

4000 = 1000 + 1000(0.055)t

4000 - 1000 = 55t

3000 = 55t

Swap

55t = 3000

t = 3000/55

t = 54.5years

t = 55years

This means it will take the deposit of $1000 55years to quadruple

What is the rule for the piecewise function shown in the graph?
andrey2020 [161]
The first choice.
The equation of this first line is -2, and since there is an open circle, it is not equal to -3.
The equation of the second line is -x-2, and there is a closed circle, so it includes -3

Which region represents the solution to the given system of inequalities?
Phoenix [80]

Answer: The intersection region shown in the graph attached is the solution of the system of inequalities.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

 Given the following system of inequalities:

\left \{ {{x+3y\leq-3 } \atop {x\geq3 }} \right.

We need to graph the lines.

We have the line:

x+3y=-3

Solving for "y", we get:

3y=-x-3\\\\y=\frac{1}{3}x-1

Knowing that m=-\frac{1}{3} and b=-1, we can graph it.

Since the symbol is \leq, the line must be solid.

The other line is:

x=3

Since "x" only takes one value, we can identify that it is a vertical line, so we can graph it.

Since the symbol is \geq, the line must be solid.

We need to substitute a point that is not on the line, into each inequalities. Let's choose the point (0,0).

Then:

0+3(0)\leq-3\\\\0\leq-3

This is false, therefore, we must shade the half that does not contain this point.

0\geq 3

This is false, so we must shade the half that does not contain this point.

The intersection region of the solutions (Observe the graph attached) of the given inequalities is the solution of the system of inequalities.
