I will leave out the base, b since it's the same for all these logarithms.

$\frac{1}{4} Log(x)-2Log(5)-10Log(y) \\ \\ Power-Rule \\ \\ Log( x^{ \frac{1}{4} } )-Log( 5^{2} )-Log( y^{10} ) \\ \\ Quotient-Rule \\ \\ Log( x^{ \frac{1}{4} } ) -Log( \frac{25}{ y^{10} } ) \\ \\ Quotient-Rule \\ \\ Log( \frac{ x^{ \frac{1}{4} } y^{10} }{25} )$

Ying is a professional deep water free diver. His altitude (in meters relative to sea level), xxx seconds after diving, is model

Wewaii [24]

Answer:

60 seconds

Step-by-step explanation:

$D(x) = \dfrac{1}{36}(x-60)^2-100$

When Ying reaches his lowest altitude, his velocity is 0.

The velocity, v(x) is the tiome-derivative of D(x).

$v(x) = \dfrac{d}{dx}D(x)$

$v(x) = \dfrac{2}{36}(x-60)\times1 = \dfrac{x-60}{18}$ (This was done by using chain rule)

Equating v(x) to 0,

$\dfrac{x-60}{18} = 0$

$x - 60 = 0$

$x = 60$

The total cost of a jacket and a pair of shoes was $99.15. if the price of the jacket was $5.81 less than the pair of shoes, wha

faust18 [17]

Let x = price of shoes
Then price of jacket would be x - 5.81
Combining the two would give you
x + x - 5.81 = 99.15
combining like terms simplifies to 2x - 5.81 = 99.15;
now adding 5.81 to both sides of the equal sign leaves
2x = 104.96
and finally, dividing both sides by 2, gives x = $52.48; which is the cost of the shoes. Recall, the cost of the jacket is 5.81 less than the cost of the shoes.
so, COST OF THE JACKET is 52.48 - 5.81 = $46.67
