Answer:  530.66 units²

<u>Step-by-step explanation:</u>

Area_{(circle)}=\pi r^2\qquad and\qquad r=\dfrac{diameter}{2}\\\\\\\implies Area_{(circle)}=\pi \bigg(\dfrac{diameter}{2}\bigg)^2\\\\\\\text{It is given that the diameter = 26:}\\A=\pi\bigg(\dfrac{26}{2}\bigg)^2\\\\\\.\quad =\pi \cdot 13^2\\\\\\.\quad =169\pi\\\\\\.\quad =\large\boxed{530.66}

-2 + 3b = 5b - 2(2b + 3) How do you solve for b?
mina [271]
-2 + 3b = 5b - 2(2b + 3)  Distribute the -2 through the parentheses.
-2 + 3b = 5b - 4b - 6        Combine like terms
-2 + 3b = b - 6                 Bring all "b's" to one side of the equation
-2 + 3b - b = b - b - 6       Combine like terms
-2 + 2b = -6                      Bring the 2 to the right side of the equation
-2 + 2 + 2b = -6 + 2          Combine like terms
2b = -4                              Isolate b by dividing both sides by 2
b = -4/2 = -2

Answer b = -2

Which function is the inverse of f(x)= x^3-6x^2+12x-8
Anna71 [15]

We're not given the choices but we don't need them.


The only way this problem is tractable to a middle or high schooler is if the polynomial is perfect cube; a little thought yields


f(x) = (x-2)^3


To find the inverse let's call f(x) x and call x y and solve for y.


x = (y-2)^3


y-2 = \sqrt[3]{x}


y = 2 + \sqrt[3]{x}
