Answer:

12.496

Step-by-step explanation:

\text{Sum}=\frac{a*(1-r^n)}{1-r}\\\text{Here a=10, r=1/5, plugging them in the above formula we get}\\\text{Sum}=\frac{10*(1-(1/5)^5)}{1-(1/5)}\\\text{Sum}=\frac{1562}{125}=12.496

If you start at vertex A and use the "shortest route" algorithm, what would be the second path to
MAVERICK [17]

Answer:

Shortest distance=|AC|/\sqrt[2]{2}.

Kindly find the attached for the figure

Step-by-step explanation:

This problem can be addressed using right-angled,

Let have right angle triangle with the shortest distance=hypotenuse;

hypotenuse=|AC|

using pythagoras theorem, we have

|AC|^2=|AB|^2+|BC|^2

Let |AB|=|BC|

|AC|^2=2|AB|^2

|AB|=|AC|/\sqrt[2]{2}

Shortest distance=|AC|/\sqrt[2]{2}

Stolb23 [73]

1. analyze data presented

It is not d because it is not greater than 80 degrees

it is not a because it is clearly not 10 degrees

making system of equations

8x+(4x+60)=180

addition

12x+60=180

move sixty to the other side

12x=120

division

x=10

Angle BEC=*x, so 8x=80

Answer: 80 degrees
