Answer:
9.22
Step-by-step explanation:
The distance formula is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using the given coordinates, the distance between them is ...
d = √((8-(-1))^2 +(0 -(-2))^2) = √(9^2 +2^2) = √85 ≈ 9.22
The length of AB is about 9.22 units.
The number is written as

To evaluate the power of ten, just remember that 10 to the power of n is a one followed by n zeroes, so ten to the sixth power is a one followed by six zeroes:

So, the number is

When you multiply a number by a power of ten, you simply add the same number of zeroes after the number. So, in this case, you only need to add six zeroes after 93:

which is 93 millions.

The formula for the area of a triangle is A = 1/2 x b x height. But, we don't have the height here. To find the height, we can use the Pythagorean theorem.
With Pythagorean theorem, we'll be finding one of the legs. If we split the original triangle in 1/2 from the vertex to the base, we now have two right triangles. Both of these right triangles have a 30 cm hypotenuse and one 13 cm leg (remember we divided the entire original triangle in half).
30^2 = 13^2 + b^2
169 + b^2 = 900
b^2 = 731
b = 
Now that we know the height of the triangle, we can find the area.
A = 1/2 x 26 x 
A = 13 x 
A = 351.48
The final area, rounded to the nearest whole number is 351 centimeters squared.
Note: Please know that depending on if the answer rounded
before using it to find the area, the final answer may then be rounded to 352.
Hope this helps! :)
