Calculate the sum of the infinite series
Rina8888 [55]

Answer:

S_\infty=250.

Step-by-step explanation:

The given infinite series is  50+40+32+\frac{128}{5}+....


The first term of this series is a_1=50.


The common ratio is r=\frac{40}{50}.

\Rightarrow r=\frac{4}{5}.


The sum of this infinite series is given by the formula,


S_\infty=\frac{a_1}{1-r}


We now substitute all the above values in to this formula obtain,


S_\infty=\frac{50}{1-\frac{4}{5}}


This implies that,

S_\infty=\frac{50}{\frac{1}{5}}


This simplifies to,


S_\infty=50\times 5


S_\infty=250.


The correct answer is C.

Help me out the meaning
WITCHER [35]

slope intercept form:

y = mx + b

m = slope

b = y-intercept

the y-intercept is the place on the y-axis (vertical) where the line crosses. In this problem, the line crosses at (0,4), meaning the y-intercept is 4.

y = mx + 4

the slope is technically the rate of change (rise over run) bewteen points.

If you take the distance from point (-1,3) and (0,4) you get a slope of 1/1, or just 1

y = 1x +4

this could also be:

y = x + 4

(because the 1 is invisible but still there)
