Given b = 12, c = 15 and a = 60° in triangle abc, use the law of cosines to solve for a. fill in the blank(s) to complete each step. round your answer to the nearest hundredth. a2 = a0 + 152 - 2a1(15) cos a2° a2 = 144 + 225 - 360(a3) a2 = a4 a = a5

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
