Answer:
11.3 units
Step-by-step explanation:
The distance can be found using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((6 -(-2))² +(-4-4)²) = √(8² +(-8)²) = √(64·2)
d = 8√2 ≈ 11.3
The distance is approximately 11.3 units.
Answer:
6.3
Step-by-step explanation:
i had the same question for school
X = number of singles matches
y = number of doubles mnathes
so we have the equation x + y = 13.......(1)
also
2x + 4y = 38 ...........(2)
(1) and (2) are the required equations
b) Find how many maches are in progress by solivng the above equations:-
x + y = 13 multiply this by -2:-
-2x - 2y = -26
2x + 4y = 38 Adding to removes the terms in x:-
2y = 12
y = 6
so x = 13-6 = 7
So the answer is 6 double matches and 7 singles are in progress.
Answer:
Step-by-step explanation:
x = 1 - i sqrt(2) ^ y = 10 + i sqrt(2)
x = 1 + i sqrt(2) ^ y = 10 - i sqrt(2)
