1. Use the function f(x)=-(x-2)' +1 to complete (a) through (h). a. Determine whether the graph of the parabola opens upward or downward.
b. Identify the vertex.
c. Determine the r-intercepts.
d. Determine the y-intercept.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

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
