try to graph y=0.4 x

Answers

Answer 1

Answer: y = 0.4x in desmos

Step-by-step explanation:

Answer 2

Answer:

Not applicable.

Step-by-step explanation:

You could use Desmos as another person answered. However, if you are graphing by hand, simply choose two points and draw a straight line between them.

For example, you could pick x = 0 and x = 1. This gives you the two points (0, 0) and (1, 0.4)

Plot those two points and use a straight edge to draw a line between the two.

In case you are having trouble plotting (1, 0.4) since it is a decimal, try setting x = 5, you will get (5, 2) which should be much easier to graph.

3+(55-111)/25 equals what

Answers

Answer:

0.76

Step-by-step explanation:

3+(55-111)/25

=3+(-56)/25

=3+ (-2.24)

=0.76

Answer:

3+(55-111)/25= 0.76

Step-by-step explanation:

Using PEMDAS, you solve 55-111 which is -56

Then you divide -56 by 25 because it is the fourth step, you get -2.24

Add three to -2.24 to get 0.76

If you round UP to the nearest tenth, it will be 0.80

Evaluate the integral using integration by parts with the indicated choices of u and dv. (Use C for the constant of integration.) xe9x dx; u

Answers

Answer:

The answer is "[tex]\bold{\frac{ \ e^{9x}}{9} (x-1)+C}\\[/tex]"

Step-by-step explanation:

Taking the integral [tex]\int x^{2x} \ dx[/tex]

Evaluating the integral by using integration:

[tex]u=x\\\\dv=e^{9x} \ dx[/tex]

Let

[tex]u=x\\\\ dv=e^{9x} dx[/tex]

Then,

[tex]\to \frac{du}{dx}= 1 \ and\ v =\int e^{9X} \ dx \\\\\to du = 1 \ dx \\\\\to v = \frac{e^{9x}}{9}\\\\\text{integrate the above value}:\\\\\int\ u \ dv = uv - \int v du \\\\Now, \\\\\to \int x e^{9X} \ dx = x \frac{e^{9x}}{9} - \int \frac{e^{9x}}{9} dx[/tex]

[tex]= \frac{ x \ e^{9x}}{9} - \frac{e^{9x}}{9}\\\\= \frac{ \ e^{9x}}{9} (x-1)+C\\[/tex]

Answer:

[tex]\displaystyle \int {xe^{9x}} \, dx = e^{9x} \bigg( \frac{x}{9} - \frac{1}{81} \bigg) + C[/tex]

Step-by-step explanation:

We will let x= children

we know that

33x+42y=276

46x+40y=292

There are a lot of ways you can solve this but I think it's easiest if we use (what I think is called elimination)

we will start by mulitiplying the second equation by 1.05 to get

48.3x+42y= 306.6

We will subtract the first equation from the second to get

15.3x= 30.6

Solve for x and get 2

Now that we know what x equals we can plug that into any equation and solve for y

we have

33(2)+42y=276

y=5

So far, we know that:

∠D = ∠J.

And that:

So, to prove that ΔDEF ~ ΔJKL by SAS, DF must be similar to JL, as those are the sides between the angle.

So:

DF:JL = 2:1.

The angles of a triangle add up to 180 degrees.

The second angle is 20 degrees larger than the smallest angle.

The third angle is 3 times as big as the smallest angle.

Find the measure of the smallest angle (in degrees)

Answers

Answer: 32 degrees

Step-by-step explanation:

small angle : x

middle angle: x + 20

large angle: 3x

Form an equation: 5x + 20 = 180

5x = 180 - 20

5x = 160

x = 160/5

x = 32

Hey in this type of questions there's no formula, you need to use your logic.

#Note that the full degree or a triangle is 180°

#The L in triangle is 90°

I see that you want to try to do it by yourself, i will give you the tips. to get the <BAD

#since <DAC is 90°, The ADB is 90° (180°-90°)

<BAD = 180° - 90° - 25° = 65°
