Which function has a range of {yly < 5}?
•f(x) = (x-4)2 + 5
• f(x) = -(x-4)2 + 5
• f(x) = (x - 5)2 + 4
•f(x) = -(x - 5)2 + 4

Show algebraically that f and g are inverse functions f(x)=x^2/-6; g(x)=square root of 2x+12

Arley is building a model of a city map. in one part of the city, three roads form a right triangle, which harley draws as triangle abc, with the following measures: m∠b=90° and m∠a=30°. in his scale model, the hypotenuse of triangle abc, ac¯¯¯¯¯¯¯¯, has a length of 817−−√ cm. what is the value of a (the length of bc¯¯¯¯¯¯¯¯)?
