The exponent indicates how many time the base is used as a factor
An extension of the Pythagorean Theorem results in what is the so-called "distance formula".
d^2=(x2-x1)^2+(y2-y1)^2, in this case you have points (-2,4) and (2,0) so:
d^2=(2--2)^2+(0-4)^2
d^2=4^2+(-4)^2
d^2=16+16
d^2=2*16
d=√32 units
d=√(2*16)
d=4√2 units
d≈5.66 units (to nearest hundredth of a unit)
Answer:
b = 4, or -4
Step-by-step explanation:
b^2 - 4*4*1 = 0
b^2 = 16
b = 4, or -4

20.75 pounds is in the more than 20, and up to 30 ; <span>$10 range.
y = 10(20.75)
y = 207.50
open circle means less than or greater than. close circle means "less than or equal to" or "greater than or equal to"
