Answer:

c=__ and a=__

Step-by-step explanation:

767.50=1.25(c)+2.25(a).

366=c+a

normally from here, I would just guess the number of adults and children. It does take a while doing it that way, but maybe you know a quicker way. Hope this helps :)

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

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

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

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

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

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

I'll just have to do manual computation per throw.

1) 3
2) 2.4
3) 1.92
4) 1.92 * 0.80 = 1.536
5) 1.536 * 0.80 = 1.2288
6) 1.2288 * 0.80 = 0.9830
7) 0.9830 * 0.80 = 0.7864
8) 0.7864 * 0.80 = 0.6291
9) 0.6291 * 0.80 = 0.5033
10)0.5033 * 0.80 = 0.4026

sum of all tries is 13.3892 or A) 13.39 feet

In an axiomatic system, which category do points, lines, and planes belong to?

Grace [21]

I think the correct answer from the list of choices above is the third option. <span>In an axiomatic system, points, lines, and planes belong to the category of undefined terms. These systems do not have definite shape and sizes. Lines and planes can extend infinitely.</span>
