Solve the following system of equations. (Write your answers as a comma-separated list. If there are infinitely many solutions, write a parametric solution using t and or s. If there is no solution, write NONE.)

${x}_{1}+2{x}_{2}+6{x}_{3}=6$

${x}_{1}+{x}_{2}+3{x}_{3}=3$

$({x}_{1},{x}_{2},{x}_{3})=$ ?

You can still ask an expert for help

Step 1

Given to solve the system of equations.

The system of equations can be solved using elimination.

To eliminate

Step 2

Plugging the value of

It is seen that the equations after plugging the value of

A movie stuntman (mass 80.0kg) stands on a window ledge 5.0 mabove the floor. Grabbing a rope attached to a chandelier, heswings down to grapple with the movie's villian (mass 70.0 kg), whois standing directly under the chandelier.(assume that thestuntman's center of mass moves downward 5.0 m. He releasesthe rope just as he reaches the villian).

a) with what speed do the entwined foes start to slide acrossthe floor?

b) if the coefficient of kinetic friction of their bodies withthe floor is 0.250, how far do they slide?

Evaluate ${\mathrm{log}}_{5}{19}^{2}/({\mathrm{log}}_{3}15)$

I did this, but I get $1.484$, whereas it's $1.038$ in my book.

I used the method:

${\mathrm{log}}_{a}b=\frac{{\mathrm{log}}_{c}b}{{\mathrm{log}}_{c}a}$

Determine the algebraic modeling a.

One type of Iodine disintegrates continuously at a constant rate of$8.6\mathrm{\%}$ per day.

Suppose the original amount,$P}_{0$ , is 10 grams, and let t be measured in days.

Because the Iodine is decaying continuously at a constant rate, we use the model$P={P}_{0}{e}^{k}t$ for the decay equation, where k is the rate of continuous decay.

Using the given information, write the decay equation for this type of Iodine.

b.

Use your equation to determine the half-life ofthis type of Fodine, That is, find ‘out how many days it will take for half of the original amount to be left. Show an algebraic solution using logs.
