Margaret makes bracelets and sells them to tourists. the function s(t) approximates how many bracelets margaret makes per hour. the function w(h) represents how hours per week margaret spends making bracelets. what are the units of measurement for the composite function s(w(
a. bracelets over hour
b. hours over week
c. weeks over bracelet
d. bracelets over week

answer: option d

bracelets over week

step-by-step explanation:

we know that the function s(t) represents the number of bracelets that margaret makes per hour.

the w (h) function represents the number of hours per week that margaret spends making bracelets

then the function:

s(w(h)) is obtained by making t = w(h)

therefore now the range of w(h) will be the domain of s(w(

then the function s(w(h)) takes as input "the number of hours per week that margaret spends making bracelets" and returns as output "the number of bracelets that margaret makes per week".

then the answer is the option d bracelets over week

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
