What is the general equation of a sine function with an amplitude of 6, a period of pi/4, and a horizontal shift of pi/2? a.) y=sin (8(x-pi/2)) b.) 8sin(4(x-pi/2)) c.) 6sin (8(x-pi/2) d,) 6sin(8x)+pi/2

All per-unit concepts rely on ratios,meaning,to provide a type of measurement

10 points? ? +++ me asap gabriella uses the current exchange rate to write the function, h(x), where x is the number of u.s. dollars and h(x) is the number of euros, the european union currency. she checks the rate and finds that h(100) = 7.5. which statement best describes what h(100) = 75 signifies? a) gabriella averages 7.5 u.s. dollars for every 100 euros. b) gabriella averages 100 u.s. dollars for every 25 euros. c) gabriella can exchange 75 u.s. dollars for 100 euros. d) gabriella can exchange 100 u.s. dollars for 75 euros.

In terms of x, find an expression that represents the area of the shaded region. the outer square has side lengths of (x+5) and the inner square has side lengths of (x-2), as shown. area: a1 x + a2 square units submit
