4. Sam owns a clothing manufacturing business. The function C(x) = 15x + 122 describes the amount it costs to employ a seamstress for x number of hours per week. What would a reasonable domain be for this function?
-40 SXS 40
b. 0 SXS 40
C. Osxs 1000
d. all real numbers
a.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

i'm not really sure how to answer that

step-by-step explanation:

he answer is x=1x3 because x=1 to x=3
