Answer:
d(A,B)=1
Step-by-step explanation:
To find distance between points A(xA,yA) and B(xB,yB), we use formula:
d(A,B)=(xB−xA)2+(yB−yA)2−−−−−−−−−−−−−−−−−−−√
In this example: xA=3 , yA=5 , xB=3 and yB=6 so:
d(A,B)d(A,B)d(A,B)=(3−3)2+(6−5)2−−−−−−−−−−−−−−−√=0+1−−−−√=1
Answer:
B) - $377
Step-by-step explanation:
Loss for the first month = -$500

Hint: if two numbers have different signs, then subtract and put the sign of bigger number.
Answer:
The sum of all integers is 774.
Step-by-step explanation:
Since √11 = 3.3166, and 3.3166 is not an integer, so the first integer is 4.
From 1 to 39, there are 39 integers. But we started with 4, so we take out 3 numbers (1, 2, 3). Therefore, there are 39 - 3 = 36 numbers left.
The total number between 4 and 39 is 36 = n.
Sn = n/2 x (a1 + an)
S36 = 36/2 x (4 + 39) = 18 x 43 = 774
