Answer:

240

Step-by-step explanation:

240 + 60 = 300 you can tell this by realising that ratio to have 4x one over the other would be 20 per 100, using this rate 3x, 240 and 60

Answer:

x = 60

Step-by-step explanation:

Length of small piece = x

length of large piece = 4x

x+ 4x = 300

5x = 300

x = 60

(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.

equation form: y = mx + b

where m is the slope, and b is the y-intercept.

slope = (y2 - y1) / (x2 - x1) = (13 -8) / (11 - 5) = 5/6

y = 5/8 x + b (replace x and y by 5 and 8)

=> 8 = 5/6 * 5 + b

=> 8 = 25/6 + b

=> b = 8 - 25/6 = 23/6

==> equation: y = 5/6 * x + 23/6
