Answer:
36.00 units
Step-by-step explanation:
Lengths of horizontal and vertical segments are easily determined by subtracting coordinates or counting grid squares:
ST = 6 -1 = 5
TR = 5 -(-1) = 6
IP = 1 -(-6) = 7
PE = 2 -(-3) = 5
The lengths of the diagonal segments are found using the Pythagorean theorem. Those lengths are the root of the sum of the squares of the rise and run. As before, you can determine those from counting squares or subtracting coordinates.
RI = √(2^2 +5^2) = √29 ≈ 5.385
ES = √(3^2 +7^2) = √58 ≈ 7.616
Then the perimeter is the sum of segment lengths:
Perimeter = ST +TR +RI +IP +PE +ES
= 5 + 6 + 5.385 +7 +5 +7.616 = 36.001
Rounded to hundredths, the perimeter is 36.00 units.
Centre of circle = (-2, -3)
Equation of the circle:
( x - ( -2) )² + ( y - (-3) )² = (√2/4)²
(x + 2)² + (y + 3)² = 1/8 (Answer D)
Step-by-step explanation:
to find mean
add all numbers, then divide by how many set they given
to find median
you need to arrange them ascending order
then what is the number in the middle
to find mode
find what most repeated number
Answer:
(x+8)(x+8)
Step-by-step explanation:
<em>Assuming x2 is x^2 </em>
(x+8)(x+8) = x^2 + 16x + 64
Continuation
