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(h))?
a) bracelets over hour
b) hours over week
c) weeks over bracelet
d) bracelets over week

Option d) bracelets over week

Step-by-step explanation:

We are given the following in the question:

s(t): This function represents the number of bracelets made per hour.

W(h): This function represent the hours per week Margaret spends making bracelets.

We have to find the units of measurement for the composite function s(W(h))

s(W(h))

s(hours per week)

(bracelets per hour(hours per week))\

bracelets per week

Thus, the composite function s(W(h)) tells us about the number of bracelets made by Margaret over week.

Option d) bracelets over week

 d) bracelets over week

Step-by-step explanation:

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
