First verify that y(x)y(x) satisfies the given differential equation. Then determine a value of the constant CC so that y(x)y(x) satisfies the given initial condition. Use a computer or graphing calculator (if desired) to sketch several typical solutions of the given differential equation, and highlight the one that satisfies the given initial condition.
x dy/dx+3y=2x5; y(x)=1/4 x5+Cx−3,y(2)=1

Answers

Answer:

at constant C = -56 satisfies the given condition of y(x)

Step-by-step explanation:

differentiate y(x) w.r.t.x

[tex]y' (x ) = \frac{d}{dx} (\frac{1}{4} x^5 +Cx^{-3} )[/tex]

= [tex]\frac{1}{4}\frac{d}{dx} (x^5) + C\frac{d}{dx} (x^{-3} )[/tex]

= [tex]\frac{5}{4} x^4 - 3Cx^{-4}[/tex]

attached is the remaining part of the detailed solution and the sketch of the several typical solutions

Step-by-step explanation:

Is F={56,777,1,2} a subset of G={2,78,64,333,1,7,56,77,900}?

Answers

Answer:

Step-by-step explanation:

F is not a subset of G because not every element in F lives in G. Even through 56, 1 and 2, all live in G, and are elements of F, 777 is an element of F but is not an element of G.

(If there is a typo, and every element in F is in fact an element in G, then the answer would be yes, F is a subset of G)

We can see that element 777 is not in set G. Hence the set F is not a subset of set G.

A set is a collection of elements not necessarily arranged in a particular pattern.

For a set A to be a subset of another set B, all elements of the set must be found in set B.

For the given set F={56,777,1,2}, we can see that the element 777 is not in the set G. Hence the set F is not a subset of set G.

Diana takes twice as long as her sister to swim across a pool. Diana swims across in 410 410 seconds. How many seconds does her sister take to swim across?

Answers

Answer:

205 sec

Step-by-step explanation:

x = sister

2x = Diana

2x = 410

x = 205

205 sec

hope this makes sense

Her sister swims across in half the time, so divide Diana’s time of 410 seconds in half...
410 / 2 = 205 seconds

Sam can ride his bike 4.2 kilometers in 6 minutes. Amanda can ride her bike 3.2 kilometers in 8 minutes. Jesse can ride his bike 3.0 kilometers in 5 minutes.

Which rider might go farther in 1 minute?

Answers

Answer:

jesse or sam i think its sam by a little bit.

Step-by-step explanation:

Answer:

Sam

Step-by-step explanation:

Find all of their speeds to find how far they will go in 1 minute, by dividing the number of kilometers by the number of minutes:

Sam

4.2/6

= 0.7 km/min

Amanda

3.2/8

= 0.4 km/min

Jesse

3/5

= 0.6 km/min

Since 0.7 is the greatest number, that means Sam is the rider that will go the farthest in one minute.

Four different mathematics books, six different physics books, and two different chemistry books are to be arranged on a shelf. How many different arrangements are possible if a) The books in each particular subject must all stand together b) Only the mathematics books must stand together

Answers

Answer:

a) 207,360 ways

b)8,709,120 ways

Step-by-step explanation:

Total number of subjects= 3

Number of mathematics books = 4

Number of physics books = 6

Number of chemistry books = 2

Part a:

Number of possible arrangement s= 3! 4! 6! 2!= 6*24*720*2= 207360 ways

In this we have included 3! because the books have to be placed in such a manner that the books in each particular subject must all stand together.

Part b:

Similarly the mathematics books must stand together so they are treated as

The total number of books will be

Physics books + Chemistry books+ Mathematics books= 6+2+1(treated as single) = 9

But there are 4 different mathematics books so these can be arranged in 4 ways.

Total number of ways in which these books can be arranged = 9! 4!= 8709120 ways.

1. (3x - 2) + (5x – 4) = 100
El valor de x

Answers

Answer:

x= 13.25

Step-by-step explanation:

If you simplify that it becomes 8x-6= 100

Then, if you rearrange it, its 8x= 100+6 or 8x=106

So that means x= 13.25

3x-2+5x-4=100
(3x+5x)+(-2+-4)=100
8x+-6=100
8x-6=100
8x-6+6=100+6
8x=106
8x/8=106/8
X=53/4
