False, y4 would equal 8 if y=2
A.
g'(x) = 6b(-5x + 1)^5 (-5)
g'(x) = -30b(-5x +1)^5
g''(x) = -30b(5)(-5x + 1)^4 (-5)
g''(x) = 750b (-5x +1)^4
b.
g(x) = <span>b(−5x + 1)6 − a
when
g(-x) = b(5x +1)6 - a
c.
</span>g'(x) = -30b(-5x +1)^5 = 0
-5x +1 = 0
x = 15
3 was gold 15 left bronze is twice of silver then bronze is 10 medals
I don't know for sure but I think it is either b or c
Answer:
SP of 8 articles =Rs 7360
Profit=15%
Now,
SP of each article =7360/8= Rs920
Wkt,
SP=CP+profit (let CP=x)
920=x+15%of CP
920=x+15÷100× x
920=x+15x÷100
920=(100x+15x)÷100
920=115x÷100
92000=115x
92000÷115=x
Therefore, x=Rs 800
CP=800(i.e Cost price of one article)
Again,
SP of 13 articles=Rs 11440
SP of 1 article=11440÷13=Rs 880
Since,SP>CP
Profit!
Profit=SP-CP
=880-800
=Rs 80
Profit%=profit÷CP×100%
=80÷800×100
=10%
