Let: f(x) = {(3,5), (2,4), (1,7)} g(x) = √(x-3) h(x) = {(3,2), (4,3), (1,6)} k(x) = x^2+5
Determine each of the following:
a.) (f + h)(1) =
b.) (k - g)(5) =
c.) (f o g)(3) =
d.) (g o k)(7) =
e.) f^-1 (x) =
f.) k^-1 (x) =
g.) 1/f(x) =
h.) (kg)(x) =

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
