Find the length of the diagonal AD in the pentagon ABCDE shown in the coordinate plane.

Mathematics
1 answer:
Xelga [282]3 years ago
6 0

Answer:

\sqrt{73} units.

Therefore, Option C is correct.

Step-by-step explanation:

We have given a pentagon ABCDE

We need to calculate its length

That means we have to find the distance of AD

So, coordinates of A(1,6) and D(4,-2)

Using distance formula:

\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Here,x_1=1,y_1=6,x_2=4,y_2=-2

On substituting the values we will get:

\sqrt{(4-1)^2+(-2-6)^2}

On simplification:

\sqrt{3^2+(-8)^2}

\sqrt{9+64}

\sqrt{73}.

Hence, the length of AD is  \sqrt{73} units.

Therefore, Option C is correct.

Furkat [3]

Answer:

13,475

Step-by-step explanation:

First hour

350 people at $17.50 per ticket

350* $17.50 =$6125

Second hour

We add 20% more

350+350*.20 =350+70 =420

There were 420 people at $17.50

420*$17.50 =$7350

Add the total for the 2 hours

6125+7350=13,475
