Simplify the expression. Enter the exact answer. Hint: You can write roots as Emotional exponents, for example 5 _32 as (623243)\"(15). However, the 243 answer to this question is a fraction without needing a root symbol. @ED Simplify the expression. M10833 + V2713 Enter the exact answer. Hints: 8 I You can write exponents with the A symbol, for example writing :13 as xAS - You can write square roots as sqrt, for example writing 1.! 103 x8 as sqrt x} @ED Use function composition to determine if f (:12) and g (1:) are inverse functions. f{:r:) 2 life: + 1 and 9(13} 2 1:3 + 1 0 Yes, they are inverse mctions. O No, they are not inverse functions. Show your work and explain, in your own words, how you arrived at your answers. There are sample student explanations in the feedback to questions 3, 5, 9, and 14 that show the level of detail that is expected in your explanations. The circumference C of a circle is a function of its radius given by C {r} = 21W. :1. Express the radius of a circle as a function of its circumference. Call this Jnction r (C). Enter the exact answer. Enclose numerators and denominators in parentheses. For example, {a b) ,7 (l | 11.). H0): @ED I]. Find 5'\" (28a) and interpret its meaning. 3" {2311-} = Number Q The radius of a circle with a circumference of 'r (2811') is 2311'. Q The radius of a circle with a circumference of 287T is 1" {28a}
