Find the distance between the points (4,-6) and (7,-6)?

Having 2 points of coordinates A(x1,y1) and B(x2,y2), then the distance AB is:

d=sqrt((x2-x1)²+(y2-y1)²)

Thus:

d=sqrt((7-4)²+(-6-(-6))²)=sqrt(3²+0)=3

Note: both points have the same y coordinate: -6. So the distance is just (x2-x1)=7-4=3

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
