30 divided by 15 is 2.
Think of it as how many 15's can go into 30? Two 15's can go into 30, so your answer is 2.

The size of a computer monitor is usually given by the length of its diagonal. A monitor's aspect ratio is the ratio of its widt

densk [106]

The length and width of the computer monitor is 23.36 inches

and 13.14 inches.

According to the given statement

we have given that

The length of diagonal of rectangular monitor = 27 inches

The length to width ratio is 16:9

So , Let the Length of monitor = 16x

and The Width of monitor = 9x

And we have to find the length and width of the computer monitor.

So, For this purpose,

From Pythagoras theorem

(Diagonal)² = Length² + width²

Put the values in it and then

27² = (16x)² + (9x)²

729 = 256x² + 81x²

After solving we get

337x² = 729

So, x² = 2.16

∴ x = = 1.46 inches

So, The length = 16x = 23.36 inches

And The width = 9x = 13.14 inches.

Hence, The length and width of the computer monitor is 23.36 inches

and 13.14 inches.

What is the factorization??

V125BC [204]

here to find the factors firstly we need to find the zeros of the function , zeros are those points at which the graph crosses or touches the x axis

Now we can see the zeros are x=4 and x=6

And we can write the factors as (x-4) and (x-6)

So the factorization would be

(x-4)(x-6)

Solve y' + 2xy = 2x^3, y(0) = 1.

dalvyx [7]

This is an ODE of the form y' + P(x)y = Q(x)
IF = $e^{ \int\limits {P(x)} \, dx }=e^{ \int\limits {2x} \, dx }=e^{x^2}$
Multiply through by IF
$e^{x^2}y'+2xe^{x^2}y=2x^3e^{x^2} \\ (e^{x^2}y)'=2x^3e^{x^2} \\ \int {(e^{x^2}y)'} \, dx = \int {2x^3e^{x^2}} \, dx \\ e^{x^2}y=x^2e^{x^2}-e^{x^2} + c \\ y=c_1e^{-x^2}+x^2-1$
But y(0) = 1
$1=c_1e^{-(0)^2}+(0)^2-1 = c_1-1 \\ c_1=1+1=2$
Therefore, solution is
$y=2e^{-x^2}+x^2-1$

PLZ HELP 8TH GRADE MATH (05.02)

Ludmilka [50]

The equation that represents that line is
y=2/3x+5.

First, you have to find the slope (the change of y over the change of x which here is 2/3. Then, you put one of the points in and solve. I used (3,7) When you input them into the equation, you get 7=2/3 (3)+_ Which gives you 7=2+_ .
5+2 is seven, so the blank is 5. So, when you do that, you get Y=2/3x+5.
If you need more of an explanation, comment. The answer is the second one

Hopes this helps :)
