Find (f•g) (-1)
Let f(x) =-2x-1 and g(x) =x^2 -1

-1

Step-by-step explanation:

let g(x) foil into f(x)   =>    (-2(x^2-1)-1)

                                      = -2x^2+1

then put (-1) into the formula => -2(1)+1

                                                 = -1

that is the answer^^

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

you have to put the graph on here with the question
