(k/3^k)(x-6)^k
enot [183]

\displaystyle\sum_{k\ge0}\frac k{3^k}(x-6)^k

converges by the ratio test for

\displaystyle\lim_{k\to\infty}\left|\frac{\frac{k+1}{3^{k+1}}(x-6)^{k+1}}{\frac k{3^k}(x-6)^k}\right|=\frac{|x-6|}3\lim_{k\to\infty}\frac{k+1}k

The limit is 1, so the series converges as long as

\dfrac{|x-6|}3

which indicates a radius of convergence of 3.

Fittoniya [83]

Answer: Luis started by adding 4.8b to both sides

Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the o
uranmaximum [27]

Let

x--------> the time in hours

y-------> the distance in miles

we know that

The speed is equal to

Speed=\frac{distance}{time}

in this problem

Speed=\frac{y}{x}

y=(Speed)*x

<u>Equation First Train</u>

y1=70x

<u>Equation Second Train</u>

y2=80x

y1+y2=600\ miles ---------> equation 1

Substitute the values of y1 and y2 in the equation 1

70x+80x=600

Solve for x

150x=600

x=4\ hours

therefore

<u>the answer is</u>

4\ hours

WILL MARK BRAINLIEST!!! HELP!​
Usimov [2.4K]

The sum of the squared legs must give the squared hypotenuse:

(\sqrt{6})^2+x^2=6^2 \iff x^2+6=36 \iff x^2=30\iff x=\pm\sqrt{30}

But of course we can only accept the positive solution, because x is a length and can't be negative.
