Answer:

Well this is a function/ quadratic question.

So using this info we can make this into a standard form for quadratics which is

ax^2+bx+c=0

In this case c is 0 and we cna just make everything else equal to zero so.

-3x^2+6x=0

Now with this we can use the quadratic formula

-b±√(b²-4ac)/(2a)

So pluggin everything in

X=-6±√(6²-4(-3)0)/(2(-3))

Now we solve

36/-6

or -6

Now we just do

-6±-6

x= -12

x= 0

These are your answers

x=-12

x=0

What is the area of the sector shown in the picture
tatuchka [14]

Answer:

The area of the sector shown is 4.75 pi

Step-by-step explanation:

First we have to know what fraction of the total circle that part represents

for that we divide 45 ​​by 360

45/360 = 1/8

now we calculate the area of ​​the circle and divide it by 8

a = ( π * 6² ) / 8

a = ( π * 36 ) / 8

a = π * 4.75

a = 4.75 pi
