Find all derivatives of y^n of the function y=√x+5

quester [9]

Hello,

As somebody has distroyed my question, (may be he have not understood ?)

i will reply to y=(√x)+5

$\displaystyle \boxed{\dfrac{d^n y}{dx^n} =(-1)^n*n!! *\dfrac{1}{2^n} *x^{-\frac{2n+1}{2} }\\}\\y'=\dfrac{1}{2} *x^{-\frac{1}{2}} \\\\y''=-\dfrac{1}{4} *x^{-\frac{3}{2}} \\...\\$

The basketball boosters are selling school t-shirts for $20 and warm up pants for $45. Last week they sold 100 items and collect

lesya [120]

They sold 76 t-shirts and 24 warm up pants.

Step-by-step explanation:

Cost of one t-shirt = $20

Cost of warm up pants = $45

Total sold = 100

Worth of sold items = $2600

Let,

x be the number of t-shirts.

y be the number of warm up pants.

According to statement;

x+y=100 Eqn 1

20x+45y=2600 Eqn 2

Multiplying Eqn 1 by 20

$20(x+y=100)\\20x+20y=2000\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(20x+45y)-(20x+20y)=2600-2000\\20x+45y-20x-20y=600\\25y=600\\$

Dividing both sides by 25

$\frac{25y}{25}=\frac{600}{25}\\y=24\\$

Putting y=24 in Eqn 1

$x+24=100\\x=100-24\\x=76$

They sold 76 t-shirts and 24 warm up pants.

You have 6 people working to set up for tonight's banquet, and each person can set up 13 tables per hour. You need to have 500 t

svlad2 [7]

6*13=78

they can set up 78 tables an hour

500/78=6.41025641026

rounded=6.4103

they would take 6-7 hours to set up 500 tables

they should start set up at 11:00 a.m

I need help with these questions.

Natasha_Volkova [10]

Answer:

25%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

Here, new number = 30, and old number = 24.

percent change = (30 - 24)/(24) * 100%

percent change = 6/24 * 100%

percent change = 0.25 * 100%

percent change = 25%
