Hello!
To find the price of one marker you divide the price paid by the amount of markers bought
6 / 20 = 0.30
A marker cost $0.30
The answer is $0.30
Hope this helps!
It would last 13.5 weeks because you would make a proportion:
12/16 = x/18 and then cross multiply. You would get 216=16x, then you have to divide both sides by 16 to get x = 13.5
600 * 0.85 (the way to work out 85% of something) = 510 flights on time
Answer:
Step-by-step explanation:
we would like to figure out the differential coefficient of
remember that,
the differential coefficient of a function y is what is now called its derivative y', therefore let,
to do so distribute:
take derivative in both sides which yields:
by sum derivation rule we acquire:
Part-A: differentiating $e^{2x}$
the rule of composite function derivation is given by:
so let g(x) [2x] be u and transform it:
differentiate:
substitute back:
Part-B: differentiating ln(x)•e^2x
Product rule of differentiating is given by:
let
substitute
differentiate:
Final part:
substitute what we got:
and we're done!
