Answer:
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
Answer:
a = 3
Step-by-step explanation:
Factorise both expressions\x² - x - 6 = (x - 3)(x + 2)
x² + 3x - 18 = (x - 3)(x + 6)
Thus both expressions have a common factor of (x - 3) , thus
a = 3
We can check the end terms first
for
(a+b)(c+d), the first term of the expanded is ac and the last term is bd
so
the expanded is x^3 and last is +7
jane will have a lst term of -7 so no
mariah wil have last term of -7 as well, so no
only rojer and nethan have last tem of +7
so we can do the rest of it by doing the OL part of FOIL
do either roger or nethan
let's do nethan
F=x^3
O=-7x
I=-x^2
L=7
yep
it is nethan
Find values that add to 5 and multiply to 6
so the answer would be (x+5)(x+1)
