Answer:

Dy/Dx=x ( 2 ln ( x ) − 1 )/ ln ^2 ( x)

Step-by-step explanation:

We have this function and let's derive it in terms of x.

y =x^2/In x

Dy/Dx=(x^2/In x)'=2/lnx *(x^2)'-(x^2/In x)'=> 2 x *ln ( x ) − x *ln ^2 ( x ) =x ( 2 ln ( x ) − 1 )/ ln ^2 ( x)

A local food mart donates 20% of it's friday's sales to charity.
Digiron [165]

Answer:

$64

Step-by-step explanation:

We have been given that a local food mart donates 20% of it's Friday's sales to charity. This Friday the food mart had sales totaling 320.00 dollars.

To find the the amount donated to the charity, we will find 20% of $320.

\text{The amount donated to the charity}=\$320\times\frac{20}{100}

\text{The amount donated to the charity}=\$320\times0.20

\text{The amount donated to the charity}=\$64

Therefore, $64 were donated to the charity.

kumpel [21]

Answer:

a = 10.36m

B = 47.7º

C = 90º

Step-by-step explanation:

we know the angle of A so we do the sin of A; Spoiler: its 0.67

0.67 = a / 15.4

0.67 * 15.4 = a

a = 10.36

----------

B = 90 - 42.3 = 47.7º
