I'm assuming you're talking about the area of a square, which is \pi r².
Plug in the radius, 26 cm, for r.
\pi 26²  <<equation

If you want the answer, \pi 26² = 2,123.7 cm²

If g(x)=4x2-16 were shifter 5 units to the right and 2 down, what would the new equation be?
Tatiana [17]
G(x)=4x^2-16

To shift to the right we have to subtract from the value of x, in this case by 5 units...

h(x)=4(x-5)^2-16

h(x)=4(x^2-10x+25)-16

h(x)=4x^2-40x+100-16

h(x)=4x^2-40x+84

Now to shift the function downwards by 2 units we must subtract the constant 2 from h(x)

h(x)=4x^2-40x+84-2

h(x)=4x^2-40x+82

Joan and her brother Justin left a hotel at the same time, driving in opposite directions at constant rates. After traveling for
inessss [21]

Answer:

Joan drive with a speed of 55 miles per hour.

Step-by-step explanation:

Given:- Travelling time (t) = 4 hours.

Travelled distance (d) = 480 miles.

Speed of Justin is 10 miles per hour faster than Joan.

To find:- Speed of Joan = ?

Solution:-

Let speed of Joan be x,

therefore speed of Justin = x+10          ---------------(from given)

Now, Total speed of Joan and Justin = x+x+10

Total speed of Joan and Justin = 2x+10 ------------(1)

Now formula for speed is,

Speed = \frac{distance}{time}

2x+10=\frac{480}{4}                        -------------(from 1 and given)

2x+10=120

2x=120-10

2x=110

\therefore x=\frac{110}{2}

\therefore x= 55

as x is the speed of Joan,

Therefore Joan drive with a speed of 55 miles per hour.
