Answer:  GCF = 5    LCM = 30

<u>Step-by-step explanation:</u>

GCF is the biggest factor they have in common.

LCM is the smallest multiple they have in common.  This can be found by multiplying the GCF by the leftover values.

                                10                    15

                                ∧                      ∧

                             <u>2</u> · 5                  <u>3</u> · 5

GCF: 5

LCM: 5 · <u>2</u> · <u>3</u> = 30

Can somebody please solve for x and y, if you get the answers correct I'll give you extra points ​
ohaa [14]

Answer:

1) x = 18 2) x = 7

Step-by-step explanation:

Edit: Decided to solve the second too! :)

1)

12/16 = x/(x+6)

12x + 72 = 16x

72 = 4x

x = 18

2)

(-4 + 4x)/64 = 27/72

-288 + 288x = 1,728

288x = 2,016

x = 7

Find the solution of the differential equation that satisfies the given initial condition.
Sliva [168]

Answer:

y=-sqrt(x^2+9)

Step-by-step explanation:

This problem can be solved with the help of separating the variables.

dy/dx=x/y

Multiply both sides by y

y dy/dx=x

Multiply both sides by dx

y dy=x dx

Integrate

y^2/2=x^2/2+c

Let's find c using the condition y(0)=-3.

(-3)^2/2=(0)^2/2+c

9/2=0+c

9/2=c.

The equation is y^2/2=x^2/2+9/2.

Let's make this a bit prettier multiplying both sides by 2:

y^2=x^2+9

Taking square root of both sides gives:

y=+/- sqrt(x^2+9)

Since we want y(0)=-3, then we will choose

y=-sqrt(x^2+9).

The number of visitors to a certain Web site triples every month. The number of visitors is modeled by the expression 8100 times
olasank [31]
Suppose we have had S visitors in n months since EIS (Entry Into Service) of the site, then : 
<span>S(n) = 8100 + 8100 * 3 + 8100 * 3^2 + 8100 * 3^3 + ... +8100 * 3^n </span>
<span>S(n) = 8100 * [ 1 + 3 + 3^2 + 3^3 + ... + 3^n ] </span>
<span>and we know that : </span>
<span>1 + 3 + 3^2 + 3^3 + ... + 3^n = (3^(n+1) - 1)/(3 - 1) </span>
<span>= (3^(n+1) - 1)/2 </span>
<span>therefore </span>
<span>S(n) = 8100 * (3^(n+1) - 1)/2 </span>
<span>finally : </span>
<span>S(n) = 4050 * (3^(n+1) - 1) </span>
<span>and this allows you to obtain the month n, if you know S(n) : </span>
<span>3^(n+1) = S(n) /4050 + 1 </span>
<span>therefore : </span>

<span>n = ln[S(n) /4050 + 1] /ln3 - 1 </span>

<span>hope it' ll help !!</span>
