3 What is the approximate
distance between points
(-7, 2) and (11,-5)?
a) 18.36 units
b) 19.31 units
c) 18.25 units
d) 10.31 units
e) 8.06 units

9514 1404 393

  b)  19.31 units

Step-by-step explanation:

The distance formula is useful for this.

  d = √((x2 -x1)² +(y2-y1)²)

  d = √((11 -(-7))² +(-5-2)²) = √(18² +(-7)²) = √373

  d ≈ 19.31 . . . units

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
