A construction site needs a security guard on site 56 hours each week. If there are 4 security guards that equally share the hours, write an equation and then solve for the number of hours each guard will need to work each week.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

it is 10.6 according to my calculations

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
