Lol Sam that isn't a math question but if you must know simply look at a modern hiragana chart. The characters you will need are for the "su" "mi" "ma" "se" and the n is a separate character by it self. One of the only ones without a syllable group and the "n" looks like an h. Sumimasen means thanks in Japanese. Hope this helps and I would appreciate a rate, thanks, or a brainliest :)
Answer:
Step-by-step explanation:
C(x)=2x^(2)-24x+720
Slope = 
Differentiating to get the slope;
= 4x - 24
Lowest cost is when the slope is zero, therfore ;
⇒ 4x-24 = 0
⇒ x = 6
substituting for x
c(6) = 
-24(6)+720 = 648
Lowest cost is $648
Answer:
f(9)=-22-9(9)+20=-83
Step-by-step explanation:
f(9) means x = 9, Just substitute 9 into the function.
-9(9) = -81
-22-81+20 = -83
Answer:
It is 21
Step-by-step explanation:
It is not hard all you got to do is 25+6=21 hope it helps plz Mark me brainlest :)
Step-by-step explanation:
a)
well, it is kind of written already :
228 miles and 6 gallons.
so, miles/gallon = 228/6 = 38 miles/gallon.
b)
it is not mentioned, but I guess we have to assume that he got the same miles/gallon ratio on this trip as well.
so, again
38 miles/gallon
and he used 9 gallons.
so, he drove 38×9 = 342 miles
