Answer:

Step-by-step explanation:

For a number to be written in standard form, it must be in a format

A×10^n

Now, n can be positive or negative, i.e n is an integer

Also, A must be between 0 and 10. It must not be outside those number

i.e 0<A<10

Therefore, to answer the question

0.00000092

The point will start to move for the negative and it will stop after the first number

If it is moving rightward, n is negative.

if it is moving leftward, n is positive

So,

9.2×10^-7 is the answer.

Then the answer is B

n=7 it moves 7 time to get to 9.2

eff can paint 28 square feet every 30 minutes. Angela can paint 50 square feet every hour. Who can paint faster, and by how many

lisabon 2012 [21]

Guessing “eff” is Jeff ;)
28 sq feet/30 min = 56 sq feet/60 minutes

Angela
50 sq feet/60 min

So Jeff paints 6 square feet more per hour.

Obtain the general solution to the equation. (x^2+10) + xy = 4x=0 The general solution is y(x) = ignoring lost solutions, if any

alukav5142 [94]

Answer:

$y(x)=4+\frac{C}{\sqrt{x^2+10}}$

Step-by-step explanation:

We are given that a differential equation

$(x^2+10)y'+xy-4x=0$

We have to find the general solution of given differential equation

$y'+\frac{x}{x^2+10}y-\frac{4x}{x^2+10}=0$

$y'+\frac{x}{x^2+10}y=4\frac{x}{x^2+10}$

Compare with

$y'+P(x) y=Q(x)$

We get

$P(x)=\frac{x}{x^2+10}$

$Q(x)=\frac{4x}{x^2+10}$

I.F= $e^{\int\frac{x}{x^2+10} dx}=e^{\frac{1}{2}ln(x^2+10)}$

$e^{ln\sqrt(x^2+10)}=\sqrt{x^2+10}$

$y\cdot \sqrt{x^2+10}=\int \frac{4x}{x^2+10}\times \sqrt{x^2+10} dx+C$

$y\cdot \sqrt{x^2+10}=\int \frac{4x}{\sqrt{x^2+10}}+C$

$y\cdot \sqrt{x^2+10}=4\sqrt{x^2+10}+C$

$y(x)=4+\frac{C}{\sqrt{x^2+10}}$

How do you find the quadratic equation for the roots 3 and 17?

Naily [24]

The roots are 3 and 17 so the distributed equation is

(x-3)(x-17)

distribute

x²-3x-17x+51

x²-20x+51

I hope I've helped!
