Rational Exponents When an expression has a for a power, the exponent is called a rational exponent. Properties of Rational Exponents Property General Rule Example Product of Powers ⋅ = 113 52∙54=54 Power of a Power () = 2 (31)2 = 3 Power of a Product () = 111 (9)2 =92 ⋅2 ©Edmentum.

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
