finlep [7]

Answer:

let alpha be x and beta be y

Step-by-step explanation:

x+y= -b/a

x+y=-1/6

and xy= c/a

xy= -1/3

1/x+1/y -xy =(x+y)/xy-xy

(-1/6)/(-1/3)-(-1/3)

1/2+1/3

How much will it cost to print a circular sign with a radius of 1.1 feet if the printing company charges $27 per square foot? us
Serga [27]

Answer: To find the cost to print a circular frame, we need to first find the area of circle.

Given: r=1.1

We know that:

Area of circle =\pi \times r^{2}

                       =3.14 \times 1.1^{2}

                       =3.7994

Also we are given cost per square foot is $27

Therefore, the cost to print a circular sign with a radius of 1.1 feet is:

3.7994 \times 27= 102.58  or $102.58
