Using the Distance Formula, calculate the distance between the three points: (3 points)
AlladinOne [14]

The distance formula between two points is d∧2=(x2-x1)∧2 + (y2-y1)∧2

The distance between Vista and Oceanside is

d1∧2=(-1-(-6))∧2+(6-2)∧2=(-1+6)∧2+4∧2=5∧2+16=25+16=41 => d=√41= 6.4

The distance between Oceanside and Alpena is

d2∧2=(0-(-1))∧2+(-1-6)∧2=1+(-7)∧2=1+49=50 => d2=√50=7.07

The distance between Vista and Alpena is

d3∧2=(0-(-6))∧2+(-1-2)∧2=36+9=45 => d3=√45= 6.7

Answer a) is Oceanside and Alpena

Answer b) is Vista and Oceanside

Good luck!!!

Anika [276]
By definition we have to:
 V = I * R
 Where,
 V: Voltage.
 I: Current.
 R: Resistance.
 The current, I amps, produced by a battery is inversely proportional to the resistance, R ohms. Clearing I have:
 I = V / R
 rewriting:
 I = V * (1 / R)
 answer:
 The equation that models the statement is:
 I = V * (1 / R)
