Answer:

[tex]y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]

Step-by-step explanation:

We begin with the differential equation [tex]\frac{dy}{dx} =(1-x)(1-y)[/tex]

Firstly, we need to get the [tex]y[/tex] and [tex]dy[/tex] as well as the [tex]x[/tex] and [tex]dx[/tex] on the same sides as each other

To do this, we can multiply each side by [tex]dx[/tex] and divide each side by [tex](1-y)[/tex]

Doing this will give us the following differential

[tex]\frac{1}{1-y} dy=(1-x)dx[/tex]

Now, we can integrate each side

[tex]\int\limits\frac{1}{1-y} \, dy =\int (1-x) \, dx\\\\-ln(1-y)=x-x^2+c_{1}[/tex]

Now, we need to solve for y

[tex]-ln(1-y)=x-x^2+c_{1}\\\\ln(1-y)=x^2-x+c_{2} \\\\1-y=e^{x^2-x+c_{2}} \\\\y=1-e^{x^2-x+c_{2}}\\\\y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]

Answer:

10 unit³

Step-by-step explanation:

Volume of the rectangular cube:

Area × lenght

Given ;

Area = 25/4 unit²

Length = 8/5 unit

Volume = Area × length

= 25/4 × 8/5

= (5 × 2) = 10 unit³

Answer:

your answer is D (6.72)

Step-by-step explanation:

substitute x by 4

Answer:

The amount of carbon in the trees and in the deer . . .

A) has increased.

Explanation:

Carbon is the basis for all living cells, it is responsible for the making and storing of energy. So if the number of energy storage molecules increases, the amount of carbon will increase because carbon is used to make those molecules.

Your question on carbon dioxide and photosynthesis having an effect is valid, but the loss of carbon wouldn't be much compared to the energy storage molecules, so we wouldn't consider that a factor in this case.

v=[tex]\pi[/tex]8(2)(6)

v=[tex]\pi[/tex]4(2)13

Answer:

||u|| = sqrt((0 + 3)^2 + (4 + 2)^2) = 6.71

||v|| = sqrt((3 + 0)^2 + (3 + 2)^2) = 5.83

slope of u = 4/2 = 2

slope of v = 5/3

Answer:

1  5/9

Step-by-step explanation:

9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is [tex]\frac{28}{3} * \frac{1}{6}[/tex]. This gets you 28/18, which is simplified to 14/9 or 1  5/9. Hope this helps!

C. [tex]f(x)=1/2x^{4}+x^{3}+x[/tex]

Step-by-step explanation:

I graphed the equation on the graph below and it looks very similar to the graph you gave.

If this answer is correct, please make me Brainliest!

The required function that are in the graph is  F(x)=1/2x^4+x^3+x.

Graph has been given, function to be determine.

Functions is the relationship between sets of values. e g y=f(x).

From the graph, function gives y = 0 twice when x =0 and x= -2.3
The only  function that gives y = 0 for x =0 and x= -2.3 is F(x)=1/2x^4+x^3+x.

Thus, The required function that are in the graph is  F(x)=1/2x^4+x^3+x.

Let [tex]x[/tex] be the smallest of the consecutive integers summing to 2020. Then the largest integer in the sum is [tex]x+4039,[/tex] so our answer is [tex]\boxed{4039}.[/tex]

For completeness, though, let's solve for the value of [tex]x[/tex] that satisfies the conditions of the problem. Recall that the sum of an arithmetic series with first term [tex]a_1,[/tex] last term [tex]a_n,[/tex] and [tex]n[/tex] terms, is [tex]\frac{n(a_1+a_n)}{2}.[/tex] Plugging in our known values gives us the equation [tex]\frac{4040(2x+4039)}{2}=2020,[/tex] which simplifies to [tex]2x+4039=1.[/tex] Thus, [tex]x=-2019,[/tex] so the 4040 consecutive integers are [tex]-2019,-2018,\dots,-1,0,1,\dots,2018,2019,2020.[/tex] Notice how everything except the [tex]2020[/tex] cancels out!

Answer:

The dot product is -2

The required dot product of (3,-1) and (1,5) is -2.

Evaluate the dot product of (3,-1) and (1,5).

It is a principle to combine two vectors. It tells about how much two vectors approaching in the same direction.

Now converts the coordinates to vector form.
a = 3i -1j
b = 1i + 5j
Dot product of two vectors a and b,
a.b = 3x1 - 1x5
a.b = 3-5
a.b = 2

Thus, the required dot product of (3,-1) and (1,5) is -2.

Answer:

LAST ONE IS angle JLK congruent to angle LNM, SAS

Step-by-step explanation:

The triangles JLK and LMN are similar by SAS congruence theorem, LJK≅ LNM.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

The triangles JLK and LMN are similar triangles.

Which means the sides are proportional and those angles are congruent.

We have to prove that JLK is similar to LMN.

By SAS rule we have "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".

So LJK≅ LNM.
